Twelve Brahman (Bos indicus) and 36 Holstein (Bos taurus) calves in Trinidad were fed on an amount of milk substitute equivalent to either 10 or 20% of their body weight each day. The diets contained either 10, 20 or 30% added fat. Nutrient balances were studied for 21 days. The liveweight gains of the calves depended on the quantity of milk fed and the breed of calf (Holstein greater than Brahman) but were independent of fat level. The Brahman calves were reluctant to accept milk substitute from a bucket. The digestibility of dry matter, nitrogen and fat was slightly higher for the Holstein than for the Brahman calves but there was little difference between the ME requirements for the 2 breeds.
在特立尼达，给12头婆罗门牛（印度瘤牛）和36头荷斯坦牛（普通牛）犊牛每天饲喂相当于其体重10%或20%的代乳品。日粮中添加了10%、20%或30%的脂肪。对营养平衡进行了21天的研究。犊牛的体重增加取决于所喂牛奶的量和犊牛的品种（荷斯坦牛大于婆罗门牛），但与脂肪水平无关。婆罗门犊牛不愿意从桶中接受代乳品。荷斯坦犊牛的干物质、氮和脂肪消化率略高于婆罗门犊牛，但两个品种的代谢能需求差异不大。
