Which cow genes contribute to better heat tolerance?

Scientists around the world are hard at work trying to determine which genes contribute to better heat tolerance in dairy cattle, and how to increase the number of cows with these genes or with increased expression of these genes – here we take a look at the latest. One major project involves a gene-editing technique​ that allows the ‘slick gene’ to be introduced into newly-fertilized eggs from cows without the gene. This is being achieved by scientists at the Centre for Tropical Live
