The influence of feeding high milk on performance, health, and absorption capability of the small intestine was studied in Holstein calves (eight males and eight females). Animals were kept in outdoor hutches bedded with straw. Treatments consisted of two quantities of milk: 1) 4.1 kg of whole milk from 3 to 48 days of age when calves were weaned and 2) gradually increasing milk from 4.1 to 7.0 kg during the first 2 wk of treatment and feeding 7.6 kg per day thereafter until day 42. Milk was reduced gradually during the 7th wk. Intake of milk averaged 4.1 and 6.7 kg per animal per day. Commercial starter, alfalfa hay, and water were offered ad libitum to all calves. Higher milk resulted in larger weight gains (615 versus 538 g/day) and less starter intake. Total dry matter intake, feed efficiency, and scour scores were not different between treatments, but rectal temperatures were greater on high milk. Female calves fed high milk showed less xylose absorption and more days medicated than females fed less milk.
在荷斯坦犊牛（8头雄性和8头雌性）中研究了饲喂高量牛奶对其生长性能、健康状况和小肠吸收能力的影响。动物饲养在铺有稻草的室外畜栏中。处理包括两种牛奶量：1）从3日龄到48日龄断奶期间，每头犊牛每天饲喂4.1千克全脂牛奶；2）在处理的前2周，牛奶量从4.1千克逐渐增加到7.0千克，此后每天饲喂7.6千克，直至第42天。在第7周期间，牛奶量逐渐减少。每头动物每天的牛奶摄入量平均为4.1千克和6.7千克。向所有犊牛自由提供商业开食料、苜蓿干草和水。较高的牛奶量导致体重增加更大（分别为615克/天和538克/天），且开食料摄入量减少。处理之间的总干物质摄入量、饲料效率和腹泻评分没有差异，但高牛奶量组的直肠温度更高。饲喂高量牛奶的雌性犊牛比饲喂低量牛奶的雌性犊牛木糖吸收更少，用药天数更多。
