The Growing Problem of Heat Stress and the Possible Role for Genetic Strategies to Mitigate Its Effects

Scientists believe that, through genetic selection, genes can be used to improve heat tolerance in Hoslteins, although what still remains is the discovery into what impact heat tolerant genes will have on the economic performance of cattle, writes P J Hansen, Department of Animal Sciences, University of Florida.
Heat stress is a big problem for the lactating cow, write Mr Hansen. Cows exposed to
