Selection strategies for thermotolerance in dairy cattle

Climate change is driving the increase in frequency of hot days and heat waves. In turn, this increases the risk of heat stress in livestock with dairy cattle the most susceptible due to their high metabolic heat load. In a recent study, researchers highlight the pros and cons of the various selection strategies for thermotolerance in dairy cattle. Reports show that heat stress, which is a serious issue for dairy cattle, will continue to persist as long as climate change continues. Heat stres
