能繁母羊二年三产高繁技术体系集成示范与结果分析

Demonstration and Analysis of the Results of the Integrated Technology System for Two-year Three-high-production Breeding In Fertile Ewes

为验证能繁母羊二年三产饲养体系和母羊同期发情、人工授精、早孕检测、妊娠期饲养、围产期护理及羔羊早期断奶等技术集成的可行性和可操作性,在上海某规模山羊养殖场开展了二轮母羊二年三产高繁技术体系的集成示范试验。能繁母羊通过系列先进饲养技术的集成应用,可实现7~8个月一个胎次的连续循环生产,形成流水线式的二年三产饲养体系。

To verify the feasibility and operability of the two-year,three-high-production feeding system for fertile ewes and the integration of the technologies of simultaneous oestrus,artificial insemination,early pregnancy detection,gestation feeding,perinatal care and early weaning of lambs,etc.The authors carried out an integrated demonstration trial of two-year,three-highproduction breeding technological system for fertile ewes in two rounds in a large-scale goat breeding farm in Shanghai.Through the integrated application of a series of advanced feeding technologies,the fertile ewes can realise a continuous cycle of production of one foetus in 7~8 months,forming a two-year and three-high-production feeding system in an assembly line.
