The Elite Program, Inc. through it’s Groom Elite™ programming will present two important classes in April to be taught by National lead instructor and Executive Director, C. Reid McLellan, PhD.  McLellan  will conduct his popular Trainers’ Exam Prep Class at Lone Star Park for a 17th time from April 5-7. Two weeks later, April 17-21, “Dr. Mac” will be lead instructor for an inaugural Basic Grooming 099, a workforce preparation class at Magdalena Farms in Lexington, Ky.

 

Lone Star Park Trainers Exam Prep Class

The Lone Star Park Trainers Exam Prep Class will be held in the Chaplain’s classroom in the Lone Star Park racing office for three days immediately following the Texas Thoroughbred Associations two-year old in training sale on April 4. Tuition is $350 and participants that register early and pay tuition before March 24th pay a discounted rate of $299.

This will be the 17th class McLellan has taught at Lone Star Park. Over 120 have participated in this class including Texas based trainer Janine Winslow, a member of the fist Lone Star Park class in 1998. Winslow saddled winners at Delta Downs and Sam Houston in February 2017. McLellan, has instructed trainers since he established an award winning equine program at Louisiana Tech University in the 1980’s. Dr. Mac is an engaging speaker who spices up otherwise dull material with personal experiences and discussion of rule changes that effect those desiring to become trainers. Information and registration online at www.groomelite.com or www.purplepowerracing.com.

 

Basic Grooming 099

Basic Grooming 099 is a 16-hour hands on class designed for people with limited (or no) horse experience who would like to take advantage of the many job openings in the Equine Industry. Class will  be held at Kenny McPeek’s Magdalena Farms on Russell Cave Road in Lexington. McPeek and others will participate as their schedules allow. “I’ll be there every  day”, McPeek tweeted (@Kenny McPeek.}

Class is being held during the Keeneland meeting  and participants will have an opportunity to attend the races and see grooms and hotwalkers in action Wednesday or Thursday.

Participants will learn how to work safely with horses, starting with approaching safely, haltering and leading. The four day (4 hours per day) class will include daily hands on practice. Participants will demonstrate on Friday what they have learned. Each person completing the course that is interested in applying for a job in the equine industry, will be evaluated and counseled as to their readiness to work with horses. In addition, contact information of trainers and farms with job openings will be provided. Elite Program staff will assist participants in finding jobs compatible with their skill level and confidence. In addition to McPeek’s Magdalena Farm, Basic Grooming 099 is sponsored in part by The Jockey Club, TOBA (though its Thoroughbred Charities of America), NTRA and the Race for Education. As a result, tuition for this class will be only $99. Class size is limited to the first 20 signing up and paying a $25 deposit to hold a spot. The remaining $74 is due April 14th . Anyone out of work and in need of a job can register and request assistance with tuition. “If a person wants to work in our equine industry we want to provide them the training necessary for them to be qualified to apply for those jobs”, McLellan stated.

A waiting list will be established if class is over subscribed. Those interested are encouraged to go to  www.groomelite.com and sign up.  Anyone without internet access is invited to call 859-252-8648 (Race for Education) or Dr. McLellan at 859-321-4377 and sign up over the phone.

The Elite Program, Inc. is a 501(C)3 non-profit that provides equine education classes through it’s Groom Elite™ curriculum.  With its initial primary mission (in 2001) to provide education to grooms and hotwalkers or Thoroughbred and Quarter Horse Racehorses, Groom Elite continually adapts and updates it’s programming that now includes courses for grooms and owners of OTTB show horses and welcomes owners and grooms of any breed. One of it’s more noteable programs is its Second Chances Groom Elite curriculum taught in five adult correctional facilities in partnership with the Thoroughbred Retirement Foundation and it’s local affiliates in which participants learn life lessons while developing an employable skill working with retired racehorses.

How to Perform CPR on a Newborn Foal

It’s bad news when a foal enters the world without taking a breath. But there’s some good news: Many foals born with beating heart and pulse, but who fail to breathe, can be revived via cardiopulmonary resuscitation (more commonly known as CPR). And there’s more good news: Both owners and veterinarians can perform CPR on a foal in need. The key is to be prepared in advance and not to wait until it’s too late to learn this potentially life-saving skill.

To that end, SallyAnne Ness, DVM, Dipl. ACVIM, reviewed how to perform CPR on newborn foals at the 2015 American Association of Equine Practitioners’ Convention, held Dec. 5-9 in Las Vegas, Nevada. Ness is an internal medicine specialist at Cornell University’s College of Veterinary Medicine, in Ithaca, New York.

Be Prepared

Ness said many veterinary clinics keep portable neonatal crash kits prepared and handy. These kits should contain the products needed to deliver life-saving oxygen to foals that fail to breath upon delivery.

She also recommended that veterinarians have on hand the injectable medications that can aid resuscitation when a foal’s heart rate gets too low or stops beating—epinephrine (adrenaline) and vasopressin (a hormone that raises blood pressure and helps maintain blood flow to the heart and brain). She also suggested printing a dosing chart ahead of time to prevent errors if medications are drawn up and administered in a hurry.

When the Foal Arrives

Ness said veterinarians and foaling attendants should rapidly assess any foal that fails to move and/or breathe upon delivery. She recommended:

  • Placing him in a sternal position (on his abdomen with tucked-under legs) and clearing the airways;
  • Identifying any rib fractures and/or congenital deficits;
  • Auscultating (listening with a stethoscope) the lungs and heart; a healthy foal’s respiration rate should be 20 to 40 breaths per minute and pulse should be 60 to 80 beats per minute, she said;
  • Palpating for pulses; and
  • Clamping the umbilicus.

This assessment should take less than a minute. She suggested giving several people specific jobs—one team leader, one to listen to the heart and lungs, etc. She also said attendants should be prepared well in advance for high-risk pregnancies or foalings.

The foaling team’s job is easy if the neonate’s heart is beating and he’s breathing properly. If he’s not breathing, however, it’s time for them to begin attempting resuscitation.

First, rub and dry the foal, she said. Sometimes tactile stimulation helps prompt the foal to breathe. Poking the muzzle and nostrils with straw can also incite a reflex that prompts the foal to take a breath. If he isn’t breathing after 10 to 15 seconds, he’ll need ventilation.

Ness said intubation is the easiest option and can be approached either through the foal’s nasal passages or his mouth. In this instance, the veterinarian will extend the foal’s neck and pass an endotracheal tube into the trachea. Then, he or she will inflate a cuff to seal the tube within the trachea and connect an Ambu Bag, which allows the veterinarian to administer breaths to the foal.

Alternatively, veterinarians and foaling attendants can use a non-intubated approach. Ness said in this case, the attendant can use a mouth-to-nose approach. To do this, Ness instructed, “You block the lower nostril (the one closest to the ground as the foal lies) with your hand and blow into the upper nostril.” Another non-intubated option is a mask with a self-inflating air pump made specifically for foals. This last option is probably the easiest and safest choice for foaling attendants and nonveterinarians, she added.

Regardless of which option the veterinarian or attendant uses, Ness said the goal is to apply 10 breaths per minute, holding the first inspiration for three to five seconds and then using quick, short breaths after that. She recommended reassessing the foal after 30 to 60 seconds.

Handling Foals Without a Heartbeat

“A foal born not breathing and without a heartbeat for any length of time is unlikely to respond to CPR,” Ness said. “But you have nothing to lose doing CPR on a dead foal. It’s doing something instead of nothing. Some can come back if the arrest began right at birth.”

She recommended beginning chest compressions immediately. The veterinarian should maintain a straight back and locked elbows and place one hand on the other on the widest part of the foal’s chest wall. Then, using his back and core muscles, begin applying 100 to 120 compressions per minute, aiming to compress the chest by one-third with each compressions. Ness noted that an easy way to get an appropriate compression rhythm is by mentally singing Stayin’ Alive by the Bee Gees and compressing along with the beat. Ironically, she laughed, Another One Bites The Dust by Queen has a similar beat and could also be used to achieve an appropriate compression rhythm. She recommended having the foaling team take turns performing compressions in two-minute cycles to prevent fatigue.

Ness said the foal should receive 30 compressions for every two breaths. If the animal is intubated, she said the compressor doesn’t need to stop. If he’s not intubated, the compressor should stop every 30 seconds so breaths can be administered. Additionally, veterinarians can administer epinephrine every four minutes to aid in revival, she said.

When to Stop

Ness recommended continuing CPR until the foal is breathing on his own and has a heart rate over 60 beats per minute. She recommended that foals that do respond positively should still be monitored closely for relapse.

She noted that if a foal fails to respond after 15 minutes, success is unlikely.

Take-Home Message

Knowing CPR and being prepared in advance to administer it to foals in need is essential for both veterinarians and foaling attendants.

“CPR is a rewarding and life-saving procedure that can result in a positive outcome when delivered quickly and with proper technique,” Ness relayed.

Myth: A Shiny Horse is a Healthy Horse

louisianathoroughbred

By Juliet M. Getty, Ph.D.

 

Fat from any source will make your horse shiny. A fatty substance called sebum, secreted from the sebaceous glands in your horse’s skin, increases when the diet is higher in fat. It coats the hair, making it reflect the sun’s rays. Any fat will do; the type of dietary fat doesn’t matter when it comes to making the hair coat shine. But it sure does matter when it comes to your horse’s health.

 

The converse is true – A healthy horse is a shiny horse…

As long as he’s shiny for the right reason – because you are feeding the right type of fat! With so many feeds and supplements available, where do you start?

 

Start with what comes naturally

Fresh grass contains 2-3% unsaturated fat consisting of a variety of fatty acids that vary in their chemical profile. There are two specific essential fatty acids that the horse’s body cannot produce and therefore must be in his diet: The omega 3 known as alpha linolenic acid (ALA), and the omega 6 known as linoleic acid. Grasses contain both of these in a 4:1 ratio of ALA to linoleic acid.

Most commercially prepared horse diets, however, have an inverted ratio of these two fatty acids because high linoleic acid fat sources such as soybean and corn oils are added to boost the fat concentration. When the omega 6 content exceeds the omega 3 content, you are asking for trouble.

 

Linoleic acid leads to inflammation

While some linoleic acid is important, too much can exacerbate your horse’s inflammatory response. Horses who are in training, working, or performing produce inflammation in their joints and muscles that can worsen when high amounts of linoleic acid are present. The aging joints of older horses are more painful when this omega 6 fatty acid is fed in large amounts. And inflammation leads to oxidative stress, which can damage all tissues throughout the body.[i]

 

ALA reduces inflammation

 Omega 3s block the formation of inflammatory molecules that are readily formed from omega 6s. Take a close look at the fat sources you are feeding to confirm that enough omega 3s are in the diet.  Read the ingredients and note the concentrations. Manufacturers of products that are high in soybean oil, for example, will often tout that the product contains omega 3s. This is true, but misleading. Soybean oil does contain about 7% omega 3s. But what they don’t tell you is that 50% of the fatty acids in soybean oil are from linoleic acid (omega 6).

 

The table below provides a better understanding of oils and oily feeds:

 

 

Approximate Fatty Acid Percentage in Oils and Oily Feeds

 
Oils and oily portion of feeds Saturated  Monounsaturated (Omega 9)[ii] Linoleic Acid (Omega 6) Alpha Linolenic Acid (Omega 3)[iii]

 
Camelina oil 13 19 16 38
Canola oil 7 54 30 7
Chia Seeds 10 7 19 55
Coconut oil[iv] 91             6 3 0
Corn oil 17 24 59 0
Flaxseeds  9 19 14 58
Hempseed oil[v] 10 12 55 18
Olive oil 16 75 8 1
Rice bran 17 48 35 1
Sunflower seeds 12 16 71 1
Soybean oil 15 26 50 7
Wheat germ 18 25 50 5

 

Hay has virtually no fatty acid content

Once fresh grass is cut, dried and stored, the naturally occurring unsaturated fatty acids are destroyed by oxygen. If hay is the predominant forage source for your horse, it is critical that you add a fat source that offers more omega 3s than omega 6s. Ground flaxseed or chia seeds are best for omega 3s. When supplementing, limit the amount fed to no more than ½ cup ground flaxseed or ¼ cup chia per 400 lbs of body weight (120 ml per 180 kg of body weight). The dosage for flaxseed oil should be 1.5 tablespoons per 400 lbs of body weight (22.5 ml per 180 kg body weight).

 

Not all equines are the same

Equines such as ponies, minis, donkeys, and mules cannot tolerate as much fat as horses. They require some fat, but generally 1/3 to 1/2 the amount given to horses, proportionate to their weight.

 

Bottom line

Read the ingredient label on any feed or supplement designed to add more fat to your horse’s diet. The ingredients may be imbalanced. While it will make your horse shine, it may do nothing to contribute to overall health and worse, it may actually increase inflammation.

[i] There is another omega 6 that is not as prevalent in the horse’s diet, known as gamma linolenic acid (GLA). GLA is receiving attention for horses’ diets because unlike linoleic acid, GLA actually reduces inflammation. GLA is found in significant quantities in hempseed oil (see note v below), and is also found in evening primrose oil and spirulina.

[ii] Omega 9s are another classification of fatty acids that do not promote inflammation and may protect the heart and blood vessels.

[iii] Fish oils are also high in omega 3s. However, ALA from plants is converted to the longer chain omega 3s found in fish oils.

[iv] Coconut oil is popular, but it has no omega 3s. Therefore, if you feed this as your only source of fat, your horse will become deficient in this essential fatty acid. He’ll be very shiny, but he will be unhealthy. Coconut oil is more than 90% saturated, with a smidgen of linoleic acid. The saturated fatty acids exist mostly as medium chain triglycerides (MCT), which is controversial because these types of fatty acids do not exist in grasses. However, MCT are metabolized differently from saturated fats and may be beneficial for metabolically challenged horses.

[v] Hempseed oil also contain approximately 2-4% Gamma Linolenic Acid, a beneficial omega 6 fatty acid known to reduce inflammation.

Study Aims to Improve Safety of Horse Farm Workers,

Results in Free Bilingual Safety Materials

Using direct input from horse farm employees, managers, and owners, a group of researchers based at the University of Maryland, Baltimore and the University of Kentucky College of Public Health has put together a set of bilingual safety training materials* designed to equip horse farm managers and workers with information needed to stay safe on the job.

The Thoroughbred Worker Health and Safety Study was a five-year research project aimed to improve the occupational safety and health of thoroughbred farm workers. The study was co-led by Jennifer Swanberg, PhD, professor, University of Maryland School of Social Work, and Jess Miller Clouser, MPH, research associate, the University of Kentucky College of Public Health. The project was funded by the National Institute of Occupational Safety and Health/Centers for Disease Control and Prevention as part of the University of Kentucky Southeast Center for Agricultural Health and Injury Prevention.

The research consisted of three phases, all of which were informed and guided by industry and community advisory councils:

  • 32 surveys and 26 in-depth interviews were conducted with farm owners, managers, and human resource personnel about the work environment and context of injuries and illnesses experienced by workers;
  • community-based surveys were conducted with 225 Latino thoroughbred farm workers about their experiences of the work environment and occupational injury and illness; and
  • an industry and community-engaged process was utilized to create educational materials based on study data to provide to farms and workers.

The research team is now releasing the three main educational materials resulting from this research. These materials are available on the project’s website at http://www.workersafetyandhealth.com/information-for-managers/

The series of 12 bilingual, graphic safety illustrations may be used as a training booklet or safety posters and aims to help educate both English and Spanish-speaking workers about safety procedures on thoroughbred farms and provide a shared language of safety. To create the content of the illustrations, the research team convened a working group of eight industry representatives including farm managers from small, medium, and large thoroughbred farms; workers’ compensation and insurance representatives; human resource personnel; and communications associates. Iterative feedback was then obtained from more than 80 farm managers, safety professionals and Latino thoroughbred workers.

safety-poster

Randy Gilbert, the farm manager at Shawnee Farm in Harrodsburg, Ky., former president of the Kentucky Thoroughbred Farm Managers’ Club, and a member of the project’s Industry Advisory Council, was a participant in the working group that drafted the safety illustrations.

“At Shawnee Farm every year we have guys that come on visas to work with the horses and maintenance and communication is key for safety. These safety posters will definitely help with communication,” said Gilbert.

Laurette Durick, human resources manager at Godolphin, a global thoroughbred breeding and horse racing team in the United Arab Emirates, also served on both the project’s industry advisory council and working group for the safety illustrations.

“These safety posters and booklets are fantastic. This is a first of its kind, as I have never seen anything like this for horse handling and the equine industry,” said Durick.

Tom Evans, owner and manager of Trackside Farm, in Versailles, Ky., and a member of the safety illustration working group added, “I would wager that my employees are 100 times more likely to study an illustration versus read text.  I think the illustrations provoke thought and show our employees that somebody cares about their safety.”

In the in-depth interviews conducted with thoroughbred farm representatives, participants described promising practices they employed to help improve employee safety and well-being, especially among non-English speaking workers. The From the Field report details those practices as a vehicle for farms to learn from one another.

Participating farms often stated that they wanted to learn what the study’s findings were. Main findings have been summarized in a series of 10 research briefs that are organized by topic area (e.g., injuries, respiratory symptoms, communication, musculoskeletal discomfort) and are available at http://www.workersafetyandhealth.com/issue-briefs/.

 

All materials are accessible for free on the project website at www.workersafetyandhealth.com. As funding permits, printed copies of the materials may also become available.  For additional information or to be added to a wait list for printed materials, please contact Jennifer Swanberg, jswanberg@ssw.umaryland.edu.

 

*While these materials were created with and for the thoroughbred industry, they may be relevant to other occupational or recreational groups. The researchers provide permission for use of the materials in other disciplines, but do not imply that the procedures depicted are universally applicable to all industries or contexts.

 

How to Predict When a Mare Will Foal

louisianathoroughbred
How to Predict When a Mare Will Foal Most deliveries transpire smoothly with no ill effects. But when a problem does occur—even a simple issue such as an easily correctable dystocia (difficult birth)—things can go south rapidly.

For some breeders, the waiting game starts as soon as the mare is inseminated. For others, it starts when she’s confirmed in foal. Still for others, it starts when she her belly grows large. Whenever that waiting game starts, all breeders want to know: When will my mare foal?

Igor Canisso, DVM, MSc, PhD, Dipl. ACT, Dipl. ECAR, previously of the University of Kentucky Gluck Equine Research Center and now an assistant professor of equine theriogenology at the University of Illinois College of Veterinary Medicine, offered some tips on how to predict when a mare will foal.

Most deliveries transpire smoothly with no ill effects. But when a problem does occur—even a simple issue such as an easily correctable dystocia (difficult birth)—things can go south rapidly, Canisso said. Additionally, “in certain situations, we don’t want let the foal suckle on its dam due to risk of developing a condition such as neonatal isoerythrolysis,” or acute hemolytic anemia caused by ingesting antibodies in the mare’s colostrum and milk that are directed against the neonate’s red blood cells, he said.

“That’s why each foaling should be attended,” he explained. “If there is a simple problem, it can easily be corrected by an experienced foaling attendant. Or, if there is a more serious condition, the mare can be referred to a clinic, or a veterinarian can be called to check the mare.

“Usually, it is best not to wait (to call the veterinarian), as after 30 minutes from ‘water break,’ every 10-minute delay in foaling decreases the foal’s survival rate by 10%,” Canisso said.

And because the vast majority of foalings take place between 6 p.m. and 6 a.m., he said, it’s important to know when you might want to start brewing coffee for overnight foal watches.

Here are some of the options owners and veterinarians can use to predict when a mare will foal.

Estimated Foaling Date—The average equine gestation length is between 335 and 345 days. So you should be able to easily calculate your mare’s estimated foaling date if you know when she was bred. For example, if your mare was bred on Feb. 10 and has an average gestation, you can tentatively expect a foal between Jan. 12 and Jan. 22 of the following year. Canisso cautioned, however, that gestation length varies substantially between breeds, time of the year (it’s usually longer when the mare is due to foal in the late winter and early spring), and individual mares, so use this method only as a guide.

If you’re unsure of when your mare was bred, your veterinarian can perform an ultrasound exam to estimate the mare’s stage of pregnancy and calculate an estimated foaling date.

Physical Signs—As the mare’s due date approaches, start watching for physical signs indicating she’s preparing to foal, including:

  • Tailhead relaxation—Canisso noted this is harder to identify in overweight, heavily muscled, or maiden mares;
  • Vulva relaxation and elongation—Canisso cautioned that some older mares might have very pronounced vulvar relaxation well before foaling while others mares will show minimal or no appreciable changes, so don’t rely solely on this factor to predict foaling; and
  • Mammary gland enlargement—Canisso said most mares’ mammary glands will begin getting larger about a month before their due date, with the most notable changes in the last two weeks prior to foaling. Maiden mares might not show substantial udder enlargement until close to parturition, he said.

Canisso cautioned that maiden mares might not display the same physical signs as seasoned broodmares.

Mammary Gland Secretions—For the last three decades many veterinarians and breeders have used mares’ mammary gland secretion electrolyte levels to predict foaling. In the normal mare, the mammary gland secretion’s calcium and potassium levels rise while sodium decreases closer to foaling. However, measuring these electrolytes to predict foaling requires a machine to analyze the levels and serial measurements. Canisso said that, commonly, breeders and veterinarians have submitted these electrolyte samples to a laboratory, which can be expensive and prohibit the practice’s use for mares not located close to a laboratory–essentially, most mares in most regions.

Because calcium is the most reliable and commonly used electrolyte, commercial kits are now available for breeders to use to estimate the mammary secretions’ calcium carbonate content and, thus, help predict when the mare will or will not foal. The commercial calcium carbonate test’s limitations include the costs and required dilutions to obtain an accurate reading, said Canisso.

Recently, Canisso and colleagues tested another method by which to predict foaling using mammary gland secretions. This time, however, they measured the secretions’ pH levels. Using commercially available pH test strips, owners can test the mammary gland secretions once daily; when the normally slightly basic secretions (pH> 8) drop to below 7 on the pH scale, the mare will likely foal within 24 hours, Canisso said. In his recent study, 11 of 14 mares foaled within 24 hours when their mammary gland secretion pH levels were 7 or lower; the remaining three study mares foaled without significant pH changes, he said.

In the same study, Canisso and colleagues compared the secretions’ pH levels with their calcium, sodium, and potassium concentrations. They found that the pH measurements were equally as effective as electrolyte measurements at predicting foaling, suggesting that pH can replace electrolyte measurements, he said. Canisso also noted that measuring pH is advantageous over electrolytes because the tests cost less; are more practical, as no dilutions are needed to determine pH; and require only a small drop of secretion to complete—this is especially beneficial for maiden mares, he said, as many maiden mares have a very small amount of pre-foaling mammary gland secretions, making electrolyte measurement very difficult.

Electronic Devices—Next, Canisso described some electronic devices breeders can use to alert them to impending foaling:

  • The Foal-Alert is a magnetic device that a veterinarian sews into the mare’s vulva. When the magnets are separated as the vulva expands during foaling, an alert is sent to a pager or cell phone, or an alarm sounds in the barn. Canisso said while this device can be used successfully, it can also cause many false alarms. Additionally, the alarm might not sound if the foal is malpositioned in the uterus or if its feet don’t penetrate the mare’s vulva.
  • The Breeders’ Alert is a position-monitoring device shaped like a small box that attaches to the mare’s halter and sounds an alarm when it detects that the mare is in lateral recumbency (the position in which they deliver a foal) for more than 15 seconds. Like the Foal-Alert, Canisso said, this device causes a lot of false alarms.
  • The last device Canisso described is the Birth Alarm. Like the Breeders’ Alert, the Birth Alarm monitors a mare’s position; however this device is located on a surcingle. When the mare lies down for more than about 8 seconds, an alert is sent to the individual monitoring the mare. As with the other two devices, Canisso said this can throw false positives, and it might be cost-prohibitive for some breeders.

Video Monitoring Systems—Finally, Canisso noted that many breeders and veterinarians employ video monitoring systems that allow them to keep an eye on the mare for signs of foaling from afar.

So which method should breeders select? Canisso said many breeders opt for a combination of the available options to give themselves the best chance to accurately predict when a mare will foal.

“Since there isn’t a single and perfect way to predict foaling in all mares, the best approach is to combine different strategies to maximize the results,” he said.

Think Before You Reach for an NSAID for Your Horse

louisianathoroughbred
Why You Should Consider Reaching Out to Your Veterinarian Before Reaching for an NSAID.
Equine lameness seems to happen at the most inopportune times, and it’s one of the main reasons for removing a horse from athletic activity. When lameness appears, horse owners are often quick to reach for a non-steroidal anti-inflammatory drug (NSAID). In fact, a survey found 82 percent of horse owners use NSAIDs without consulting their veterinarian.1 But that may not be the smart move.

“It’s important for horse owners to consult their veterinarian before giving an NSAID,” says Hoyt Cheramie, DVM, MS, Senior Manager, Merial Large Animal Veterinary Services. “The best option – and the shortest path back to soundness – may be a medication, treatment or protocol the horse owner hasn’t considered.”

“In addition, no medication is without risks,” says Cheramie. “Your veterinarian is the best person to help you monitor your horse’s health for potential side effects or lack of efficacy. Keeping your veterinarian involved, even if it’s just informing them of your treatment decision, will provide them with important information in the future if the issue comes up again.”

Your equine veterinarian considers many factors before prescribing any treatment, including an NSAID:

  • What is the horse’s history?
  • Is the diagnosis a simple lameness or could it be something else?
  • What treatment options are available?
  • What is the horse owner’s budget and resources?

If your veterinarian does recommend an NSAID, they’ll take into consideration:

  • Has this horse been given this medication before?
  • What dosage should the horse receive, and what is the best route of administration?
  • What are the potential side effects of the treatment or medication?

The decision-making process can be complex, which is why most equine NSAIDs are available only with a prescription. If for some reason your horse does have a reaction or fails to improve, ensuring your veterinarian is fully aware of the situation will be a benefit.

Regardless of discipline, when your horse is lame, it can impact not only your short-term competitive goals but also your horse’s long-term health. So, before you reach for that old tube or bottle, talk to your veterinarian about all of your options to help effectively manage lameness, pain and inflammation in your horse.

The end of one year and the beginning of another is an exciting time for many breeders, as it likely marks the last trimester of their mares’ pregnancies. Due to the rapid changes that occur in the last few months of gestation, it is imperative that owners monitor mares closely. Udder development, abdominal distension, and presence of vaginal secretions are some of the most important changes to monitor. 

Average gestational length is around 11 months and a week, or 335 to 342 days. However, sometimes the duration is shorter or longer (330 to 360 days or more) with no detrimental effects on the fetus or mare.  

Remove mares from endophyte-contaminated tall fescue pastures no later than 10 months of gestation to prevent abnormal prolonged pregnancy, decreased milk production, and even abortion, and work with your veterinarian to determine whether a mare needs to be medicated with a prolactin stimulation product to negate the endophyte’s effects. 

Lack of udder development four to six weeks before foaling in a mare that is not grazing tall fescue or is not on pergolide medication for equine Cushing’s disease should not be a cause for alarm. Normal udder development starts in the month prior to delivery. Typically, the udder becomes engorged within the last few days before foaling (parturition). Waxy accumulation at the nipples from early colostrum (the mare’s antibody-rich first milk) production occurs one to four days before foaling but sometimes earlier. Occasionally, milk leaks from teats for several days to weeks before foaling, resulting in colostrum loss. If this occurs, work with your veterinarian to find an alternative source of colostrum for the neonate before foaling.

Take premature lactation (a clinical sign of placentitis) seriously and have your veterinarian examine the mare’s uteroplacental thickness (abnormal thickness can indicate issues such as placentitis). At the same time he or she should perform a vaginal exam and make sure no vaginal discharge is visible until a few days before delivery. Although abdominal distention is normal and more noticeable in the last trimester, have sudden and excessive distention evaluated to rule out hydrops conditions (excess placental fluids) or excessive edema (fluid swelling) that can weaken the ventral abdominal musculature. 

By the tenth month of gestation, the fetus will no longer be able to turn around. At this time mares can be examined using rectal ultrasound to determine fetal presentation. Although we can’t predict complications such as dystocia (a difficult birth), we can determine if the foal’s head is facing the cervix properly (anterior presentation). If the veterinarian can’t visualize the foal’s eyeball through the rectal wall on an ultrasound exam, this could indicate a possible breech (posterior presentation). Additionally, the veterinarian can evaluate uteroplacental thickness, examine the vulva for signs of discharge, and open the vulva if the mare had ever undergone a Caslick’s operation (sutures to prevent reproductive tract contamination). The veterinarian should also boost the mare’s immune system by administering her 10-month vaccinations; this will help her produce antibodies that will ultimately pass through the colostrum to the newborn in the first few hours after birth. The vaccines given will depend on the mare’s geographic location and her risk of disease exposure. Owners should move mares to a foaling facility, if necessary, at this time. 

During the final two weeks before her due date, the veterinarian should examine the mare frequently for physical changes such as vulvar laxity and edema, mucoid (resembling mucus) vulvar discharge, broad ligament (which suspends the uterus in the abdomen) relaxation, and udder size and secretion. Predicting the exact time of parturition is challenging, particularly in first-time foaling mares. The vet can, however, measure calcium and magnesium levels in udder secretions, which will increase in the last two to four days before parturition, to predict the time of foaling.

The actual foaling process is short and explosive, with delivery usually occurring in 20 to 30 minutes. If labor progression is slow, or if delivery lasts longer, the veterinarian should assess the mare immediately and correct any foal positioning abnormalities if necessary.

Gas Colic – Common, but Preventable!

louisianathoroughbred

By Juliet M. Getty, Ph.D.

 Gas colic is the least serious form of colic. That’s the good news. The bad news is that it’s very common. So common, in fact, that it is often overlooked as “just gas,” like you might get when you eat too much pizza. However, never be complacent about gas colic because it can lead to complications such as displacement or twisting of the large colon.[i] Truth is, if you’re feeding correctly, gas colic should not happen. And if it does, then you’re more than likely doing something wrong.

Where does the gas come from?

The fibrous portion of plants doesn’t get digested until it reaches the hindgut (cecum and large colon) where it is broken down by the resident microbial population. This process, known as fermentation, produces volatile fatty acids (to be used for energy) as well as gas. Gas production is normal. In fact, a horse who has sufficient forage will often develop a “hay belly.” This is not fat, but rather, evidence of healthy gas production.

Horses produce tremendous amounts of gas, which is why they flatulate a lot! But, if the gas doesn’t adequately pass through the large colon, with all its twists and turns, it can build up.  And there you have it – gas colic.

Here’s what we know so far

The exact reason for gas colic is difficult to assess, especially since most forms of colic involve some gas accumulation. But in general, gas colic can be caused by:

  • Inadequate forage consumption
  • Stall confinement
  • Stress
  • Ulcers
  • Intestinal inflammation
  • Inadequate exercise
  • Dehydration
  • Changing forage sources too quickly
  • Introducing new feeds too quickly

 

Gas colic is common because of two widespread practices

1) Limiting forage disrupts proper digestion. Horses require forage to be available 24 hours a day, all day and all night. Not that they actually eat during the entire 24 hours, but rather to simulate a natural environment where they can graze on forages as they wish. When they know that forage is always available, they slow down their eating, take time for a nap or socializing, and come back for more when they are ready. If this basic, foundational instinct is not met, the horse releases hormones which can create muscular spasms and interfere with the normal functioning of the digestive tract.

On top of that, hormones become out of balance, leading to inflammation of the hypothalamus, insulin resistance, and obesity. This is not the focus of this article, but I encourage you to read more about it.[ii]

When there is insufficient forage, the stomach accumulates acid, creating pain and mental discomfort. When the hay finally arrives, the horse will gorge himself, eating quickly and every bit in sight. He won’t chew as well, resulting in large amounts of undigested feed reaching the microbial population, resulting in excessive gas production.

Forage restriction also leads to ulcers anywhere along the gastrointestinal tract. Consequently, gas production increases because ulcers can interfere with digestion, allowing more undigested feed to reach the hindgut. Since ulcers can also bleed, blood flow to the large colon is diminished, inhibiting normal hindgut motility.

2) Confining your horse to a stall or small run/paddock reduces hindgut motility. When motility slows, gas cannot be expelled. The large colon is made of muscles which contract and relax in a peristaltic motion, moving digested material and waste products (including gas) along its length. When these muscles become “flabby,” movement becomes sluggish, leading to intestinal distress (colic). Gas accumulates, the intestine distends and pain-sensitive receptors in the large colon are stimulated, causing your horse to experience intense pain.

Blood circulation to the digestive tract is improved by moving around – simply grazing in the pasture, looking for the next tasty morsel, will add up of over the course of the day to more exercise than giving a horse an hour working in the arena. Standing for hours in a small space is very damaging to your horse’s digestive health.

And then there’s stress

There are literally thousands of studies showing the negative impact of stress on people’s health. Everything from irritable bowel syndrome, to heart disease, to autoimmune diseases, to obesity is impacted by constantly barraging our tissues with stress hormones, leading to a cascade of events that results in poor health. At the cellular level, the exact same thing is true for horses.

Stress exacerbates inflammation, which can damage any part of the body, but when the digestive tract is affected, the risk of colic goes up. Inflammation leads to ulcers, malabsorption, water imbalance, visceral fat accumulation surrounding the intestines, and microbial flora changes, all creating a scenario for colic.

Pasture turnout is the best way to reduce stress. Even a few hours each day will have a positive impact. If there isn’t pasture available, turn-out in an outdoor exercise area such as an arena (making sure there’s hay and water available) will reduce gas colic risk.

 Feed changes need to be slow, with a little help

The hindgut microbial population must have time to adjust to any new food, so make sure give your horse’s digestive tract time to make the transition.

If you have to change hay every few weeks, an abrupt change of feed will put your horse at risk. Instead, do a little advanced planning and set aside a few bales of old hay, while slowly switching over to the new hay. You may find yourself regularly blending old and new hays since it is best to take approximately one week to make the adjustment. While doing this, offer your horse a prebiotic containing bacterial fermentation products to help adjust to a new forage source.[iii]

If you’re adding a commercially fortified feed to your horse’s diet to meet additional energy demands, make sure he already has some hay in his belly before feeding a concentrated meal. If you need to introduce a new product, take 2 to 3 weeks to safely change to a new feed.

Beware of weekly bran mashes. A bran mash, or any new feed for that matter, if unfamiliar to the hindgut microbial population, can trigger a dangerous colic attack. If you want to feed a warm bran mash, consistency is key – it must be fed every day, not once a week. Be sure to introduce it gradually and since bran is very high in phosphorus, choose a commercially fortified version that has added calcium.

Helpful supplements

In addition to a forage foundation, there are several supplements worth considering:

  • B vitamins offer support for the digestive tract lining, as well as reducing stress. I recommend adding them to your horse’s diet prior to traveling or performing.[iv]
  • Yeast – both live yeast and yeast culture, protect the immune system by keeping the hindgut bacteria in good health.[v]
  • Colostrum has the ability to heal ulcers, protect against the damaging impact of NSAIDs, and increase healthy cell proliferation. It also heals leaky gut, caused by cecal acidosis and excess fermentation of carbohydrates.[vi]

Consider clean feeding

You are likely familiar with the movement to change your diet to “clean eating.” This simply means reducing the amount of “junk food” in your life and replacing it with whole, natural foods, clear of pesticides, preservatives, and inflammatory ingredients. In the horse world, there are two ingredients that we typically feed that are highly inflammatory: sugar and soy products. Most commercially fortified feeds contain both of these. Since these feeds often contain preservatives as well, fed over time, they can have a major impact on your horse’s overall health.

 Slow feeders may be the answer

Slow feeder nets and containers are designed to simulate grazing.[vii] They must be kept full, or you’ll defeat your purpose. But when your horse knows that he will always have access to forage, he becomes calm and relaxed, rests more often, and walks away from the hay, knowing that it will still be there when he returns. In other words, slow feeders help your horse to “self-regulate” and eat only what he needs to maintain a healthy body condition. [viii]

Change what you can – every little improvement has an impact

Colic is rare among horses who graze on large pastures, simply because of their easy lifestyle and consumption of fresh, nutritious grasses. My goal in writing this article is to set a high standard, for all of us to strive toward. Still, I am vividly aware that many, if not most of you rely on boarding facilities and are not able to offer your horse acres of pasture. But once we know where we want to go, we are better able to get there.

Look into possible ways to increase outdoor grazing time. You may need to consider changing barns. Or perhaps your facility offers limited pasture turnout. Also consider using slow feeder systems in a stall at night so there is hay left over in the morning. In other words, the most significant change you should strive toward is how to make hay available 24 hours a day.[ix]

Every little improvement makes a difference, for your horse and for other horse owners boarding at the same location. You might just become a trailblazer!

Bottom line

Take control of your horse’s environment and feeding, by focusing on Nature’s rulesto avoid gas colic. Remember, your horse is a grazing animal, requiring a steady flow of forage at all times. Feed him, simply, like a horse!

Warm Winter Could Affect Tall Fescue Toxicosis in Broodmares

louisianathoroughbred

By Krista Lea

 

LEXINGTON, Ky., (Feb. 8, 2017) — Mild weather this winter is likely the cause of higher than average concentrations of a toxic substance in tall fescue called ergovaline that has been observed in Fayette and Bourbon pastures in Central Kentucky, according to University of Kentucky College of Agriculture, Food and Environment experts. Tall fescue toxicosis in broodmares, which is caused by ingesting ergovaline, is rare in the early months of the year due to typically cold winter temperatures.

Naturally occurring tall fescue is often infected with an endophytic fungus that can produce ergovaline, a known vasoconstrictor – something that causes the narrowing of blood vessels. This has been blamed for prolonged gestation and low milk production in late term pregnant mares. The UK Horse Pasture Evaluation Program sampled three farms in Fayette and Bourbon counties this year and found a handful pastures with higher than average ergovaline concentrations for the time of year.

“These levels would not be alarmingly high in May, because pastures would have other forages such as bluegrass and orchardgrass actively growing, providing sufficient dilution in the total diet. However, other grasses are not active in February, therefore horses are likely to consume more tall fescue, especially in pastures that were overgrazed last fall,” said Krista Lea, UK Horse Pasture Evaluation Program coordinator.

According to Ray Smith, UK forage extension specialist, dilution is the key to minimizing the effects of ergovaline.

“Farms should move mares to pastures where more desirable forages are available and tall fescue is less prevalent,” he said. “Keeping good quality hay in front of mares on pasture will also dilute any ergovaline the horses may consume.”

He urged farm managers whose mares experience foaling complications to work closely with their veterinarian to evaluate all possible causes.

“There are so many ways and reasons foaling can go wrong,” said Cynthia Gaskill, veterinary toxicologist at the UK Veterinary Diagnostic Laboratory. “Any time foaling complications are observed, all appropriate tissues and samples should be sent to us to evaluate possible causes immediately.”

According to Gaskill, no direct test is available for ergovaline levels in animal tissues, so diagnosing suspected cases of tall fescue toxicosis includes ruling out other possible causes and determining ergovaline concentrations in forages or bedding. In certain situations, domperidone can be administered to alleviate the symptoms of tall fescue toxicosis, but this can have other side effects and is costly, making prevention the ideal treatment.

Pasture, hay and bedding can all be evaluated for ergovaline concentrations at the UK Veterinary Diagnostic Laboratory for $52 per sample. Pasture samples of tall fescue should be frozen and transported on ice to the lab immediately. Hay and bedding samples should come from several bales and can be transported at ambient temperature out of direct sunlight. Detailed instructions on sampling can be found at http://www.uky.edu/Ag/Forage/Tall%20fescue%20sampling.doc

Local county extension agents can assist farms in sampling pastures, hay or bedding. More information can be found on the UK Forage Extension website, http://www.uky.edu/ag/forage, or by emailing UK’s forage group at UKForageExtension@uky.edu

Use Your Stethoscope Before You Need It!

Use Your Stethoscope Before You Need It!

By Dr. Juliet M. Getty

 

Your emergency kit likely includes a stethoscope – a highly valuable piece of equipment during any urgent health situation. Knowing your horse’s normal heart rate and gut sounds beforehand will allow you to better assess the seriousness of the situation — so use your stethoscope now.

A resting pulse is typically between 32 and 40 beats per minute (ponies’ are slightly higher). Place the stethoscope in front of the girth area, just behind the elbow. Using the sweep second hand on your watch or a stop watch (usually a feature on your cell phone), count the number of beats for 30 seconds and double it to get beats per minute. Measure at various times of day, before and after eating, and at any change in circumstances or activity level; this will give you a clear idea of how your horse generally responds to his environment. Marked deviation from normal (without obvious explanation such as exercise) can indicate the presence of infection, pain, or illness.

Your stethoscope is especially useful for listening to gut sounds. It is normal and healthy for sounds to come from the digestive tract due to the movement of feed, gas, and fluid. Intestines are made of muscles; processing forage continuously provides the necessary exercise to keep these muscles in good condition. Normally, the sounds will be low in pitch with some growling. Colic occurs when there is a change within the intestines, ordinarily due to obstruction, gas[i], or torsion, and sounds change or stop altogether. If you don’t hear any noise, or if the sounds have become higher pitched, significantly slowed, or sound hollow, it likely indicates colic and you should contact your vet immediately.

Practice listening to four areas of the gut: along the upper barrel and the lower flank area on both sides. Generally speaking, sounds from the upper left come from the small colon and tend to be high pitched and of short duration. The lower left has sounds from the large colon. On the upper right, the sounds come from the large colon and cecum whereas the lower right has the large colon. However, the point of origin for gut sounds is not completely predictable; the important thing is to identify a variation from your horse’s normal sounds.

Deviations from normal in pulse or gut sounds may have many possible explanations, so unless you have extensive experience, you should never put yourself in the position of diagnosing colic or other disorders. But you can be a valuable resource to your veterinarian if you know what is normal for your horse and can identify a change, before illness happens.
