摘要
本次调研与2014年7~8月在辽宁省东部山区的7个县开展,采用实地调研和电话问卷调研相结合的方式,共获得调研问卷38份。调研内容围绕母羊繁殖及羔羊生产情况,开展了辽宁绒山羊养殖规模、羊群结构、母羊繁殖效率情况、产羔及羔羊生长情况、羔羊哺乳及采食情况等方面的调查研究,掌握了第一手数据。调研分析获得结论为：1引起妊娠母羊流产的主要原因是外力顶撞;2在被调研38家羊场中,2014年春季平均产羔率为115.39%,产多羔（两羔及以上）率为21.36%;3羔羊死亡主要原因为腹泻,发生在出生后第一个月内;4产羔母羊无奶或缺奶比例较高,主要原因是母羊体况差和产多羔。因此建议：1加强妊娠母羊管理,防止顶撞;2为增加产羔数,需注意选择产双羔的亲本作为种用;3加强羔羊在出生后的第一个月的关林,要特别防控腹泻;4改善繁殖母羊体况,采取代乳或集中哺喂代乳粉的方式解决羔羊缺奶问题。
