| 摘 要： | 目的]对青海高寒草地放牧藏羊妊娠期和哺乳期进行补饲试验。方法]通过转变草地畜牧业生产经营方式,对青海高寒草地放牧母羊在妊娠期和哺乳期进行补饲效果研究。结果]与传统游牧养殖方式组相比,母羊关键繁育期补饲组产羔率显著提高,为98%;母羊关键繁育期补饲组4月龄羔羊成活率高于传统游牧养殖方式组。母羊关键繁育期补饲组初生重和2月龄日增重与传统游牧养殖方式组差异极显著(P<0.01)。母羊关键繁育期补饲组母羊分娩后体重和断奶体重比对照组大,而断奶失重比对照组小,差异均极显著(P<0.01)。结论]对高寒放牧藏母羊在关键繁殖期进行补饲,能有效促进高原畜牧业的高效发展。

| Abstract: | Objective] The research aimed to make the supplemental feeding test on Qinghai alpine grazing Tibetan ewes in pregnancy and lactation stages.Method] Through changing the production and management manners of pasture stockbreeding,the supplemental feeding effect of Qinghai alpine grazing Tibetan ewes in pregnancy and lactation stages were studied.Result] Compared with conditional grazing breeding group,the lamb rate in the supplemental feeding in the key breeding season group was significantly enhanced,being 98%.The survival rate of 4-month-old lamb in the key breeding season in the supplemental feeding in the key breeding season group was higher than that of control group.The birth weight,2-month-old weight and the 2-month daily gain in the supplemental feeding in the key breeding season group had extremely significant difference with conditional grazing breeding group(P<0.01).The weight after parturition and weaning weight of ewes in supplemental feeding in the key breeding season group were higher than that of control group,and the weaning weight loss was lower than that of control group,with extremely significant differences(P<0.01).Conclusion] Supplemental feeding on the alpine grazing Tibetan ewes in the key breeding season could promote the efficient development of plateau animal husbandry. |
