Heat stress occurs when animals are exposed to environmental temperatures in excess of 25°C (the upper critical temperature), particularly in combination with high relative humidity or sunshine. High humidity makes the sweating mechanism relatively ineffective, thereby making cattle unable to maintain their core body temperature. Affected cows attempt to reduce heat load by reducing exercise, feed intake and lactation. They actively seek shade and wet areas. As their body temperature rises… CONTINUE READING
