Are Some Equine Breeds On The Edge Of Extinction?

Genetic erosion is a concerning topic for all facets of the livestock industry, including horses. Selective breeding for high-yielding food and fiber results in economic values for some livestock; in horses, selective breeding is not done for these reasons, but for competitive advantage or specifics like color, temperament or size, says Cliff Williamson of the […]

The Benefits Of Genetic Testing for Horses in Training

Without a doubt, the successful training of Thoroughbred racehorses is a complicated process, which includes the formidable task of selecting a suitable race for each horse. While the conventional methods of doing so  are well understood augmenting them with the support of genetic testing can ensure that each horse is given the best opportunity to […]

Are Horses That Crib Cognitively Impaired?

Cribbing is a familiar stereotype in horses that is commonly seen as a type of stress relief. The term ‘cribbing’ refers to a horse horse placing his top teeth on a fixed structure and contracting the lower neck muscles. The activity has no obvious function. Cribbing appears to become more frantic at times of stress, and […]

Genetic Differences Determine If Standardbreds Trot Or Pace

Scientists have recently identified genetic variants that are responsible for determining whether a horse trots or paces. An algorithm has been created that is 99.4 percent accurate at determining which way a horse will move. Prior to this discovery, it was known that a “gait-keeper gene” existed; mutations on the DMTR3 gene resulted in a […]

New Research Generates A Ten-Fold Increase In Data About Equine Genetic Code

Research led by scientists at the University of Louisville and the University of Kentucky has produced a more complete picture of the domestic horse reference genome, a map researchers will use to determine the role inherited genes and other regions of DNA play in many horse diseases and traits important in equine science and management. […]

Genetics Behind Horse Height Helps Breeding Programs

Horse owners often try to predict the adult height of young horses. According to Welsh researchers*, knowing which genes play a role in regulating body size, including height, could provide important information regarding growth and development mechanisms, and contribute to mare and stallion selection in breeding programs. “A horse’s size influences both performance and maintenance decisions,” […]

Cloning Controversy: The Highlights

Cloning has allowed horse lovers the option of keeping a (genetic) piece of their beloved equines around for longer much than the average horse’s life expectancy. First accomplished on a sheep in July of 1996, cloning has come a long way, but core issues remain: Cloning is expensive. Producing a cloned horse can cost more […]

What Does It Mean When A Horse Is ‘Foot-Sore’?

Most horse owners have heard the phrase “tender-footed,” meaning foot soreness, and the same number have probably dealt with the problem in one way or another, but what causes the problem and what can you do to avoid it? “Foot soreness is characterized by sensitivity when pressure is applied to the foot,” said Laura Petroski-Rose, […]

How Genes Play A Role In Stallions’ Attraction To Mares

Research shows that the amount of effort a stallion invests in his ejaculates, referred to as ejaculate economics, can vary based on his attraction to the mare he is intended to breed and the teaser mare. Surprisingly, that attraction can be affected by the genetics of both the mare and stallion. What makes a mare attractive […]
