摘　　要：试验旨在研究开食料中添加糖蜜对犊牛生长性能及腹泻率的影响。选用24头3日龄健康荷斯坦奶牛犊牛作为试验动物,按体重相近原则随机分为4组,每组6头,对照组和试验1、2、3组分别饲喂不同方式处理的犊牛颗粒料。结果表明,在30日龄时,试验2组犊牛体重显著高于对照组(P<0.05);60日龄时,试验2、3组犊牛体重显著高于对照组(P<0.05),试验2组犊牛体高和胸围显著高于对照组(P<0.05);在整个试验期,试验2、3组犊牛采食量显著高于试验1组和对照组(P<0.05);在腹泻率方面,对照组最低,试验1组最高。因此,从对生长性能及体尺指标来看,颗粒料、玉米压片和小麦压片按7∶2∶1比例且再加5%糖蜜进行喷涂处理的犊牛开食料要优于其他各组,且饲料利用率最高。The experiment was aimed at the effects of different structural starters on growth performance and diarrhea rate in calf. Three days of health Holstein cows were choosed as a test sample, then divided into four groups according to the prin- ciple of similar weight randomly, and each group contained 6 calves. The four groups were fed different grain material respec- tively. The results showed that compared with the control group, at the age of 30 days, calves weight in 2 group were signifi- cantly higher （P〈0.05）; at the age of 60 days, calves weight in 2 and 3 groups were significantly higher （P〈0.05）, the body height and chest circumference in 2 group were significantly higher （P〈O. 05）. During the whole trial period, the feed intake of calf in 2 and 3 groups were significantly higher than the test group and control group （P〈0.05）. In the rate of diarrhea, the control group was minimum, but 1 group was the highest. From the growth performance and body measurements, the results showed that the calf starters with ratio of calf feed pellets, steam flaking corn to steam flaking wheat being 7 ： 2 ： 1, and adding 5 % molasses spray were better than other groups, and had the highest feed utilization rate.
