Two studies, the first in the USA and the second in Australia were undertaken to investigate respiration rate (RR) responses of growing grain fed cattle exposed to hot climatic conditions. In the first study (Exp 1) eight Hereford x Angus x Simmental steers were exposed to 24 h cyclic hot conditions (24 degrees C to 39 degrees C). In the second study (Exp 2) six Murray Grey x Hereford steers were used. In this study ambient temperature (T-a) ranged from approximately 24 degrees C to 45 degrees… CONTINUE READING
