摘　　要：为了解决呼伦贝尔草原牧区长期舍饲方式下,家畜产羔后营养不足导致母畜体况恢复慢和仔畜生长缓慢问题,本试验通过适时补饲的方法,研究补饲对呼伦贝尔短尾羊生长状况改善的影响。结果表明:补饲可以显著提高不同年龄阶段母畜的日增重(P<0.05),最大日增重为12~18月龄母畜可达到33.50±4.87g/d,增重程度随着年龄的增大而减小。补饲可以显著提高羔羊的生长速度(P<0.05),其中公羔的日增重显著高于母羔(P<0.05)。公羔最大日增重可以达到233.53±1.84g/d。试验户和对照户的仔畜生长速率与羔羊出生重呈现规律显著的二次函数关系,由此可知,产羔后补饲对羔羊的后期生长具有积极的影响。In order to solve the problems slow recovery and growth of the livestocks after breedingin the way of long - term drylot feeding, in Hulun Buri Grassland, the effects of supplementary feeding on the growth status of Hulun Buff short tailed sheep was studied in this paper. Eight similar pastures were selected in Evenki Hulun Buir grassland pastoral area , including 3 pastures which were not supplementary feeding and 5 pastures were supplementary feeding. The results showed that supplementary feeding improve ewe daily weight gain in different age signally （P 〈0. 05）, the biggest daily weight gain was happened in the age of 12 - 18 month which ranched to 33.50 ±4. 87g/ sheep/d. The weight gain decreased with the age increased. Supplementary feeding improve the lamb growing rate significantly （ P 〈 0.05 ） , and the daily weight gain of male higher than the female （ P 〈 0. 05 ）. The biggest weight gain of male is 233.53 ± 1.84g/sheep/d. There was a significant quadratic equation relationship between daily weight gain and birth weight at experiment and control. In a word, supplementary feeding after breeding is good for lamb growth later.
