Several studies have highlighted the benefits of different additives on heat stress in dairy cows, but few have focused on the economic benefits of such additives. Researchers from the University of Melbourne carried out an economic analysis of supplementing either betaine or fat, or a combination, as heat-relieving strategies in lactating Holstein Friesian cows. The frequency and severity of heat stress events impacting most dairies during the summer periods are expected to increase with inc
