摘要：

通过对陕北白绒山羊在自然放牧基础上进行不同营养水平的补饲，以研究对其繁殖性能的影响。选取繁殖母羊120只，分为四组，每组30只。对照组，每天补饲0.2 kg玉米，其余三组为试验组，分别每天补饲混合精饲料0.2 kg，0.3 kg，0.4 kg。试验主要测定繁殖母羊的受胎数，产羔数，羔羊初生重，羔羊断奶重，计算受胎率，产羔率，羔羊成活率。结果表明对照组与试验组对繁殖母羊繁殖性能的各项指标影响不显著(P>0.05)。补饲0.2 kg玉米基本就满足了繁殖母羊的营养需要。

Abstract:

This test was to study the affect of feeding different nturient levels on the reproductive performance of Shanbei White Cashmere Goat.Selected 120 breeding ewe which in the same age from Di Qing Plateau,divided into four groups,each group for 30.Control group,feeding 0.2 kg corn everyday,the other three groups for the experimental group,feeding mixed concentrate for 0.2 kg,0.3 kg,0.4 kg respectively everyday.Test were measured the conception number,the number of new-born lambs,the lamb birth weight,the weaning weight,the calculate of conception rate,the lambing rate,the lamb survival rate of breeding ewes.The results showed that the control group and experimental group on the reproductive performance of breeding ewes is unsignifican.affect of the index （P> 0.05）.Feeding 0.2 kg of corn to meet basic nutritional needs of breeding ewes.
