Abstract excerpt
Previous studies have examined the effects of heat stress on dairy cattle and have estimated genetic parameters of heat tolerance for milk production traits. To further investigate heat stress in Canadian dairy cattle and to identify potential mitigation strategies through genetic selection, this study evaluated the relationship between somatic cell score (SCS) and the temperature-humidity index (THI) in...
