EFFECT OF ENVIRONMENTAL TEMPERATURE ON HEAT PRODUCTION AND ITS ENERGY COST FOR THERMOREGULATION IN DAIRY HEIFERS

A study was conducted using four dairy heifers to determine the effect of 10, 20 and $30^{\circ}C$ environmental temperatures on the physiological responses and heat production, at a fixed level of TDN intake ($60.5\;g/kg^{0.75}\;d$). The analysis showed significant affects of environmental temperat...
