RESPONSES OF YOUNG CALVES, ON TWO LEVELS OF FEEDING, TO TRANSPORTATION

摘要

The effect of transportation on energy metabolism in young calves was assessed at two feeding levels by indirect calorimetry during 5.5-day experimental period. Twenty-six Holstein-Friesian male calves were assigned in a 2 X 2 factorial arrangement of treatments. Calves were fed below or near the maintenance requirements (270 or 420 kJ metabolizable energy per kg M(0.75) per day). At 5 days of age, 13 calves were transported. The applied transportation procedure was aimed to mimic common transport of young calves. The other 13 calves were controls.
