摘要
为提高肉羊养殖效益并优化畜牧业管理,进行肉羊同期发情人工授精技术的应用效果评估。通过设计3组对照试验,探究营养补给、环境温度、孕酮栓种类(海绵栓与硅胶栓)等因素对母羊吊栓情况、生殖道异常情况、妊娠情况的影响。结果表明,试验组别1和2对比发现,补充亚硒酸钠维生素ADE粉母羊受胎率提高2.5%,但对吊栓率和生殖道异常率的影响较小;试验组别3和4对比发现,较低的环境温度会降低受胎率;试验组别2和3对比发现,相比海绵栓,硅胶栓能够显著提高受胎率,并减少吊栓率和生殖道异常率。该研究成果可为同期发情人工授精技术在肉羊品种改良的高效推广应用提供技术支撑。
In order to improve the efficiency of sheep breeding and optimize animal husbandry management,the application effect of synchronous estrus artificial insemination technology for sheep was evaluated.By designing three sets of controlled experiments,the effects of factors such as nutritional supplementation,environmental temperature,and types of progesterone suppositories(sponge suppositories and silicone suppositories)on the suspension status,reproductive tract abnormalities,and pregnancy status of ewes were explored.The results showed that the comparison between experimental groups 1 and 2 showed that supplementing with sodium selenite vitamin ADE powder increased the conception rate of ewes by 2.5%,but had little effect on the rate of suspension and reproductive tract abnormalities;Comparing experimental groups 3 and 4,lower environmental temperatures can reduce the conception rate;Comparing experimental groups 2 and 3,compared with sponge suppositories,silicone suppositories can significantly improve conception rates and reduce the rates of hanging suppositories and reproductive tract abnormalities.The research results of this article can provide technical support for the efficient promotion and application of synchronous estrus artificial insemination technology in the improvement of sheep breeds.
