Preweaning Intake and Postweaning Dietary Energy Effects on Intake and Metabolism of Calves Weaned at 26 Days of Age

Meat and Animal Science Department, and Department of Dairy Science, University of Wisconsin, Madison 53706

Holstein calves (n = 48) were used to evaluate whether preweaning feeding and metabolism after abrupt weaning at 26 d of age. Calves were fed only whole milk until d 19 of age. From d 19 to 26. management affects postweaning DMI calves were provided one of three isocaloric and isonitrogenous diets: milk at 15% of d-1 BW, milk at 12% of d-1 BW plus a grain-based supplement added to the pail, or milk at 12% of d-1 BW and drenched (force-fed) with the supplement. After weaning, calves were offered a low or high energy (1.7 or 5.8% ether extract) starter. From d 26 to 36, starter intake was similar between calves fed the supplement in the pail and those fed only milk but lower than for calves drenched with supplement. Plasma NEFA increased threefold from d 26 to 27, and calves fed only milk had higher NEFA than drenched calves. From d 26 to 42, plasma VFA of drenched calves were higher than those fed only milk. Except for an increase in plasma NEFA at d 36 and 42, high energy starter did not affect any variable. Preweaning drenching of calves stimulated postweaning adaptation to dry diets. Intake post-weaning appears to depend more on physiological adaptation to dry diets than to preweaning feeding management.
