Inbreeding depression and durability in the North American Thoroughbred horse.

Animal genetics - 1 Jun 2023

Hill Emmeline W, McGivney Beatrice A, MacHugh David E

Abstract excerpt

The proportion of the genome containing runs of homozygosity (ROH) affects production traits in livestock populations. In European and Australasian Thoroughbreds inbreeding, quantified using ROH (FROH ), is associated with the probability of ever racing. Here, we measured FROH using 333 K SNP genotypes from 768 Thoroughbred horses born in North America to evaluate the effect of inbreeding on racing traits in that...
