A 12-week course on equine genetics is being offered by Equine Guelph, the horse division of the University of Guelph in Ontario, Canada.
The course will provide students the opportunity to understand the importance of genetics and how it can influence a horse’s ability to perform or render it susceptible to certain diseases, unsoundness or even a genetic disorder.
Since the mapping of the equine genome was completed in 2007, genetic research has now provided the horse industry with the proper tools to better understand how to care for horses, how to utilize their genetic potential, and how to breed a better horse.
“A horse can be no more than its genetics allow,” says equine genetics course instructor Dr Diane Winkleman-Sim, an equine science lecturer at the University of Saskatchewan.
“This means that the upper limit of a horse’s ability is determined by its genetic makeup, and understanding this provides us with an invaluable tool for selecting horses for their potential.
“By the same token, understanding the horse’s genetic potential and limitations allows us to develop training and management programmes based on the horse’s own biology.”
Within this course, Winkleman-Sim says students will look at the biological basis of genetics, including what it is and how it is passed from parents to offspring; Mendelian genetics and how traits controlled by only one or two genes are inherited; as well as single gene genetic disorders that have been identified in horses, including widespread disorders such as HYPP (Hyperkalemic periodic paralysis) and HERDA (Hereditary equine regional dermal asthenia) in quarter horses and SCID (Severe Combined Immunodeficiency) in Arabians.
Multigenic determination of coat colour and examination of gene action pertaining to performance traits and nature (genetic) vs. nurture (environment) aspects of performance traits, as well as how to select animals when breeding for performance, will also be covered.
“As owners, trainers, caregivers and service providers in the equine industry, it behooves us to address the biology of the horse in developing programmes to maximize the quality of the horse’s life and to match horses with the careers for which they are best suited, thereby enabling us to make the most of our equine companions,” says Winkleman-Sim.
Equine Genetics is part of the Equine Science Certificate continuing education program and will be included in Equine Guelph’s Fall 2013 online lineup.
Other course offerings include Management of the Equine Environment, Equine Nutrition, Equine Functional Anatomy, Equine Growth and Development, Stewardship of the Equine Environment, Equine Business Management, and Equine Journalism. Registration is now open, with courses running from September 9 to December 1, 2013.
