Trotter or Pacer Stallion? Genetic test can predict

Prof. McCue at the University of Minnesota has developed a method to accurately predict gait profiles (pacer vs. trotter) in Standardbred horses using genetic testing. This test examines a specific set of single nucleotide polymorphisms (SNPs), and uses a conditional inference tree algorithm to predict the gait profile of a horse with over 99% accuracy.

The results of this test will help owners, trainers and breeders to:

  • identify preferred natural gait of their horses: pacer or trotter
  • plan and train their horses for suitable races
  • fine-tune breeding programs with designed matings

While mutation in DMRT3 gene can be used as a necessary indicator for “gaitedness”, it is fixed in Standardbreds and is not useful to predict the preferred gait profile. It is worth noting that nearly 20% of the offspring of Standardbred trotter stallions go on to race as pacers (Cothran et al., Anim Genet. 1987).

Phase of Development

Pilot scale demonstration in an independent population (99.4% accuracy)

Features & Benefits

  • Early prediction of preferred gait profile helps owners/trainers choose and plan for suitable races
  • Accurate prediction (over 99%) using a set of genetic indicators
  • No need to rely on ancestry, or physiological proxies such as back lengths/loin strength to predict the gait of the horse
  • Reliable, early determination saves time, money, and other resources
  • Breeders can develop effective breeding programs

Applications

  • Horse training
  • Horse racing
  • Diagnostic tool for equine traits
  • Diagnostic tool for selective horse breeding
