摘　　要：为了研究羊高效双羔疫苗对藏绵羊繁殖率和羔羊成活率的影响,在同一栋羊舍内,将300只经产母羊随机分为对照组和试验组,每组150只。对照组和试验组母羊饲养水平为:燕麦青干草自由采食,每天补饲由拉萨新希望实业股份有限公司提供的怀孕母羊补饲颗粒料0.6 kg。试验母羊与公羊分开饲养后第3日颈部皮下注射羊高效双羔疫苗1 mL。3周后,每日上午8:30-9:00公羊拴系试情布进入母羊群进行诱导发情,寻找发情母羊。给发情母羊颈部皮下注射羊高效双羔疫苗1 mL后再进行人工输精。3周后,对返情母羊颈部皮下注射羊高效双羔疫苗1 mL后再进行人工输精。5个月后记录产羔情况和羔羊成活情况。结果表明,对照组母羊产羔138只、繁殖率为92%,试验组经产母羊产羔222只、繁殖率为148%,两组对比差异极有统计学意义(p<0.01);对照组羔羊成活130只、繁活率为94.20%,试验组羔羊成活217只、繁活率为97.75%,两组对比羔羊繁活率差异有统计学意义(p<0.05)。故羊高效双羔疫苗可有效提高藏绵羊经产母羊的繁殖率,在全舍饲不影响羔羊的繁活率。In order to study the effects of highly effective double lambs vaccine on reproductive rate and lamb survival rate of Tibetan sheep,300 multiparous ewes in the same sheep house were randomly divided into control group and experimental group,with 150 lambs per group. The feeding level of the control group and the experimental group was as follows:oat hay was taken freely,and the pregnant ewes were fed with 0.6 kg pellet provided by Lhasa New Hope Industrial Co.,Ltd. every day. The ewes were raised separately from the rams on September 1 st,and subcutaneously injected with 1 mL of double lambs vaccine on the 3 rd day after feeding. Three weeks later,the rams tied estrus test cloth went into the ewes group to induce estrus and look for estrus ewes at 8:30-9:00 every morning. After subcutaneous injection of 1 mL double lambs vaccine into the neck of estrous ewes,artificial insemination was carried out. After 3 weeks,the ewes were injected subcutaneously with 1 mL of double lambs vaccine in the neck before artificial insemination. The lambing and survival were recorded after 5 months. There were 138 lambs in the control group,with 92% reproductive rate and 222 lambs in the experimental group with 148% reproductive rate. There was a significant difference between the two groups(p<0.01). 30 lambs survived in the control group with 94.20% survival rate,while 217 lambs survived in the experimental group with 97.75% survival rate. There was significant difference in the survival rate between the two groups(p < 0.05). High efficiency double lambs vaccine can effectively improve the reproductive rate of Tibetan ewes,but it does not affect the survival rate of lambs in the whole house.
