Holstein Calves

In two experiments Ayrshire and Holstein bull calves were weaned off whole milk onto dry feed at various ages, ranging from 14 to 35 days, to determine the earliest age at which calves may be weaned successfully. Ayrshire calves were weaned at 14, 21 and 35 days with no significant differences in weight gains or feed intake to 15 wk of age. Holstein calves were weaned off whole milk or fermented colostrum at 17, 21, 24, 28 and 35 days of age with no significant differences in weight gains and feed intake to 12 wk of age. Also, the feeding of either fresh whole milk or fermented colostrum did not sigificantly affect animal performance. Several calves weaned at less than 21 days, in each experiment, refused to eat dry feed. Post-weaning deaths of several calves weaned at 21 days were attributed to prolonged pre-weaning scours or illness at time of weaning. It was concluded that healthy male calves may be weaned successfully at 21 days of age but weaning should be delayed for calves afflicted with scours or other illness. Agressive eaters may be weaned as early as 14 days of age but some calves weaned at less than 21 days of age may encounter problems in adapting to dry feed.

Dietary Treatments

Fish silage, preserved with 3.5% formic acid, was fed to Holstein bull calves weaned onto dry feed at 3 wk of age. Dietary treatments were: (1) soybean meal-supplemented calf starter, (2) a low protein grain mix combined with fish silage in a 2:1 ratio (wt/wt), and (3) the same grain mix combined with fish silage in a 4:3 ratio (wt/wt). Initial acceptance of the fish silage diets equalled that of the soybean meal diet. Over the 10-wk period, feed consumption, weight gains, and feed:gain ratio tended to be slightly poorer as the proportion of fish silage in the diet increased. Only during the final 6 wk of the trial were weight gains significantly reduced by calves on the fish silage diets. It was concluded that fish silage can be used as a protein source for young calves.

Daily Gain

During three consecutive seasons 129 bull calves, consisting of 45 Holstein, 45 Shorthorn × Holstein (Crossbred) and 39 Shorthorn, were pail fed whole milk, plus a limited quantify of meal ration after the first 3 weeks until marketed at approximately 95 kg liveweight. Holsteins reached market weight at an average of 57 days, a shorter period than for either Crossbreds or Shorthorns. This was due to a combination of Holsteins’ higher initial weight and average daily gain.Carcass grade favored Shorthorns over Holsteins, with Crossbreds intermediate. There was little difference in dressing percentage among breeds. Shorthorns produced more boned loin, rib, shoulder round, sirloin, and fat trim and had a larger eye of lean area than Holsteins but less cutlets, leg bottom, rump and bones. Results from the higher grade of carcasses produced by Shorthorns must be weighed against Holsteins’ greater daily gain, shorter time on feed and less total milk required to reach market. In nearly all aspects, Crossbreds were intermediate.
