贵州黑山羊羔羊早期断奶育肥试验

Fattening Test on Early Weaning Lamb of Guizhou Black Goat

选择体重接近的贵州黑山羊1月龄羔羊20只,随机分为2组,对照组正常断奶,试验组实施30天断奶及直线强度育肥,在断奶期与育肥期设计不同的日粮进行饲喂。结果表明:早期断奶羔羊对断奶日粮适应期过渡正常,试验组与对照组体重差异不显著(P>0.05)。早期断奶补饲可以明显增加贵州黑山羊的体重及日增重(P<0.01)。试验组体尺在105日龄显著高于对照组(P<0.05),在120日龄试验组羔羊的体长、体高和胸围都极显著高于对照组(P<0.01)。结论:在毕节对贵州黑山羊实施早期断奶直线育肥是可行的。

The experiment select 1 month old Guizhou black goat 20 and randomly divided into 2 groups,the control group of normal weaning,experimental group received 30-day weaning and fattening line strength,in the weaning and fattening period were fed diets with different design.The results showed that： early-weaned lambs weaning transition to the normal diet adaptation period,experimental group and control group body weight was not significant（P0.05）,supplementation can significantly increase the early weaning of Guizhou black goat＇s body weight and daily gain（P0.01）.The experimental group＇s body size was significantly higher than the control group on105 days of age（P0.05）,120 day-old experimental group lambs body length,body height and chest circumference were significantly higher than the control group（P0.01）.Describes the implementation of Guizhou black goat fattening line early weaning is feasible in Bijie Area.
