Study: Inbreeding, Specific Genetic Marker May Decrease A Thoroughbred’s Likelihood To Race

Scientists at the University College Dublin, the University of Edinburgh, and the Irish equine genetic testing company Plusvital conducted a study to determine the relationship between inbreeding and the likelihood of a Thoroughbred to make it to the races. The study, titled “Inbreeding depression and the probability of racing in the Thoroughbred horse,” was published June 29, 2022 in the peer-reviewed scientific journal “Proceedings of the Royal Society B.”

The study looked at the genomes of 6,000 Thoroughbreds across Europe and Australia, and demonstrated that for every 10 percent increase in inbreeding, there was a 44 percent lower chance that the horse would make it to the races. In addition, the study pointed to a specific genetic marker which was related to a significant decrease in the likelihood that that horse would make it to the races.

According to the study, that genetic marker (EFNA5) is responsible for encoding the ephrin ligand, which is broadly expressed during tissue development and repair. Among its roles are: neonatal muscle development and regeneration, regulation of cardiomyocytes, skeletal development, fracture repair, and cartilage repair.

Ask Your Veterinarian: Putting Broodmares Under Lights

louisianathoroughbred

by Paulick Report Staff

 

Veterinarians at Rood and Riddle Equine Hospital answer your questions about sales and healthcare of Thoroughbred auction yearlings, weanlings, 2-year-olds and breeding stock.

Question: When it comes to putting broodmares under lights for cycling are overhead lights or mask lights better? And why does it work?

Dr. Peter Sheerin, Rood and Riddle Equine Hospital: In many breeds, Jan. 1 is considered the birthdate for all horses in the breed, no matter when they are born. This can put late-born foals at a disadvantage when competing or at yearling sales. Because of this, many breeders want their mares to foal as early as possible.

The horse is considered a long day breeder, meaning they are cycling when the days are longer. Mares left at natural conditions in the Northern Hemisphere will typically start cycling late March to early April. Mares further north will start cycling later than mares closer to the equator. Researchers determined that by artificially increasing the day length and the amount of light that mares were exposed to, one could get mares to cycle earlier. Mares did not begin to cycle for 60 to 75 days after the beginning of exposure to longer days. So, for a breeding season that starts Feb. 15, one would start lights Dec. 1 at the latest.

Louisiana Breeding Program attracting Quality Mares

louisianathoroughbred

Dam of New Track Record setting Hollis brings class to Louisiana breds

On Friday, December 10th six-year-old gelding Hollis (Street Sense-Miss Inclined, by Pulpit) set a new track record at Oaklawn Park sprinting 5 ½ furlongs in 1:02.17, defeating favorite Nashville in the process. 

His dam, Miss Inclined, is indicative of the type of mares that Louisiana is attracting into its state bred program. The multiple stakes placed Pulpit mare is the dam of five winners from five starters out of seven foals, including stakes winner and new track record setter, Hollis as well as G1 placed Lady Lily. 

Miss Inclined now has two Accredited Louisiana bred fillies, a yearling by Liam’s Map and a weanling by Clearly Now. She is bred back to McKinzie.

The influx of monies coming into Louisiana thanks to legislation allowing sports betting and historical racing are expected to make the Louisiana Breeding Program even more attractive. More information about the Accredited Louisiana Thoroughbred Breeding Program can be found on the Louisiana Thoroughbred Breeders Association website at www.Louisianabred.com or by calling 504-947-4676

louisianathoroughbred
The Jockey Club has released Report of Mares Bred (RMB) statistics for the 2021 breeding season. Based on RMBs received through October 18, 2021, The Jockey Club reports that 1,016 stallions covered 27,829 mares in North America during 2021.

The Jockey Club estimates an additional 2,500 to 3,500 mares will be reported as bred during the 2021 breeding season.

RMB statistics for all reported stallions in 2021 are available through the Fact Book section of The Jockey Club’s website at jockeyclub.com.

Kentucky traditionally leads North America in Thoroughbred breeding activity. During 2021, Kentucky’s 200 reported stallions covered 16,727 mares, or 60.1% of all of the mares reported bred in North America. The number of mares bred to Kentucky stallions increased 2.0% percent compared with the 16,391 reported at this time last year.

Of the top 10 states and provinces by number of mares reported bred in 2021, stallions in Kentucky, California, Ontario, and Indiana covered more mares in 2021 than in 2020, as reported at this time last year.

North American Foal Crop Trends and Market Share

MarketWatch: North American foal crop trends

 

Even as the North American Thoroughbred foal crop continues to contract, down 6.9% over the last three years and down 45.4% since 2000, the top five producing states have remained a constant.

Kentucky, California, and Florida have been the steady top three joined by New York and Louisiana that flip-flop their rank from year to year. The recently released figures on the 2020 North American foal crop show New York slightly ahead this year with 652 reported foals to Louisiana’s 647, but both at even with 3.3% of the overall foal crop for the United States, Canada, and Puerto Rico.

louisianathoroughbred

The Jockey Club today reported that 1,552 stallions covered 31,198 mares in North America during 2019, according to statistics compiled through Sept. 29, 2020. These breedings have resulted in 19,677 live foals of 2020 being reported to The Jockey Club on Live Foal Reports.

The Jockey Club estimates that the number of live foals reported so far is approximately 85-90 percent complete. The reporting of live foals of 2020 is down 3.4 percent from last year at this time when The Jockey Club had received reports for 20,363 live foals of 2019.

In addition to the 19,677 live foals of 2020 reported through Sept. 29, The Jockey Club also received 2,476 No Foal Reports for the 2020 foaling season. Ultimately, the 2020 registered foal crop is projected to reach 20,500.

The number of stallions declined 4.8 percent from the 1,630 reported for 2018 at this time last year, while the number of mares bred declined 4.0 percent from the 32,508 reported for 2018.

The 2019 breeding statistics are available alphabetically by stallion name through the Resources – Fact Book link on The Jockey Club homepage at jockeyclub.com.

Kentucky annually leads all states and provinces in terms of Thoroughbred breeding activity. Kentucky-based stallions accounted for 55.3 percent of the mares reported bred in North America in 2019 and 60.2 percent of the live foals reported for 2020.

The 17,240 mares reported bred to 228 Kentucky stallions in 2019 have produced 11,851 live foals, a 2.9 percent decrease on the 12,200 Kentucky-sired live foals of 2019 reported at this time last year. The number of mares reported bred to Kentucky stallions in 2019 decreased 1.2 percent compared to the 17,446 reported for 2018 at this time last year.
