摘　　要：研究全舍饲精料补充料对2~4月龄驴驹生长的影响,探究其是否可以代替半哺乳式饲喂。试验采用随机分组设计,将12只2月龄驴驹随机分为2组,试验组6只,对照组6只。试验组驴驹2月龄断奶,进行了60 d饲养试验,对照组半哺乳饲喂。结果表明,试验组的日增重(0.46 kg/d)大于对照组的日增重(0.33 kg/d),试验组的增重系数显著高于对照组的增重系数(P<0.05);试验组与对照组体尺指数变化不显著(P>0.05);全舍饲补充精料饲喂和半哺乳对血液生化指标的影响较小。全舍饲精料补充料不会阻碍驴驹的生长发育,增重效果更佳;全舍饲精料补充料可以代替半哺乳式饲喂方式,驴驹可在2个月断奶。In order to study the effects of feeding concentrate supplements on the growth of 2 to 4-month-old donkey foals,and to explore whether the concentrate supplements can replace semi-lactation feeding.Twelve 2-month-old donkeys[2]were randomly divided into 2 groups,6 in the test group and 6 in the control group.Donkeys in the experimental group were weaned at the age of 2 months,and a 60-day feeding experiment was conducted,while the control group was fed with semi lactation.The results showed that the daily weight gain of donkeys in the test group(0.46 kg/d)was greater than that in the control group(0.33 kg/d),[3]and the weight gain coefficient of the test group was significantly higher than that of the control group(P<0.05);the difference of body size index between the test group and control group was not significant(P>0.05);the effect of the two feeding methods on blood biochemical indexes was small.As a conclusion,feeding concentrate supplement would not hinder the growth and development of the donkey foals,instead,the effect of weight gain was better.Therefore,the concentrate supplements could replace the semi-lactation feeding mode,and the donkey could be weaned at the age of 2 months.
