摘　　要：通过对沿河山羊进行舍饲养殖试验研究,结果表明:沿河山羊在舍饲环境条件下其发情规律、怀孕期均与放牧山羊基本一致。舍饲母羊胎均产羔率为187.88%,略高于放牧母羊产羔率(184.85%)。舍饲羔羊断奶成活率为88.71%,比放牧羔羊断奶成活率(81.97%)提高8.22%。舍饲山羊发病死亡率为12.50%,比放牧山羊低76.54%。舍饲羔羊公母平均初生重为1.71±0.57 kg,2月龄体重为8.88±1.64 kg,6月龄体重为17.85±2.69 kg,9月龄体重为27.37±3.32kg,比放牧羔羊分别提高1.79%、27.95%、26.78%和26.16%,除羔羊初生重相接近外,其余各月龄阶段的体重差异均极显著(P<0.01)。舍饲羔羊各月龄阶段的体高变化不大,体斜长、胸围均有明显提高,增长幅度在10%以上,差异显著(P<0.05)。可见,沿河山羊在舍饲环境条件下具有良好的适应能力,而且舍饲还有利于疫病的防治,促进生长发育,值得在全县范围内推广。The experiment on the confined farming of Yanhe Goat shows that the estrus laws and preganant period of Yanhe goat in coufined farming are basically in accord with those of the grazing. The lambing rate of confined ewes were 187.88% which was somewhat higher than the grazing ewes（ 184.85% ）. The live rate of 88.71% for iambs in confined farming after weanling increased 8.22% than that in grazing （81.97%）. The death rate due to sickness for confined goat was 12.50% which was 76.54% lower than that of grazing goat. The average body weight at birth was 1.71 ±0. 57kg,and the body weight at 2months was 8.88 ± 1.64 kg,17.85 ±2.69 kg at 6 months and 27.37 ±3.32kg at 9 months,which improved respectively 1.79% ,27.95% ,26.78% and 26.16% than that of grazing. Except for the close body weight at birth, the others were extremely different（ P〈 0.01 ） ;The body height of confined lambs at different months changed a little, but the body oblique length and chest girth obviously increased over 10% ,with a significant difference（P〈0.05）. So it proves that the Yanhe goat can adapt the confined environment. In addition, the confined farming is advantageous to prevent diseases and can promote the goats growing and developing which is worth popularzing in the county.
