| 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: | The effect of different nutritional level of supplementation on reproductive performances in adult female shanbei white cashmere goat on the basis of native graze was investigated in present study. 120 goats were divided into four groups, each group include 30 females. 0.2 kg corn was supplied to control group, 0.2kg, 0.3 kg and 0.4 kg concentratemixture were supplied to the other groups every day, respectively. Conception rate, lambing percentage, birth weight, weaning weight, survival rate were recorded, ... |
