Recent research shows that increasing parental age at conception has a detrimental effect on race speed. When a split-second can separate the horses at the end of the race, the slightest advantage can give the winner the edge. Research from the University of Exeter found that the speed of Thoroughbred horses declines as the age of their parents when they were conceived increases.

A poll on HORSEJournals.com asked the question: Should equines be cloned? Some 83 percent of respondents said no, not until more research has been done; 15 percent said maybe, in special situations with strict parameters; just two percent said yes, and that registration of clones should be allowed.

Male horses are usually castrated to moderate unwanted male behaviour and limit unintended reproduction. Vasectomy, interrupting the vas deferens to prevent sperm being released, is an option to prevent breeding while still maintaining male behavioural characteristics. It is performed less frequently in horses than in other species.
