Optimising gut health to overcome performance losses

Global climate change is influencing animal production even in temperate climates. As the number of days when the temperature humidity index exceeds animals’ comfort threshold rises, heat stress has become one of the most important ambient stressors in animal production worldwide. Heat stress occurs as an animal’s heat gain exceeds the heat it can dissipate. Modern production animals, selected for rapid growth, are more susceptible to heat stress, and adverse effects include decreased p
