Application of Estrus Identification,Breeding and Artificial Insemination Techniques for Sows in Large-scale Pig Farms
摘要
Abstract
In the breeding and management of large-scale pig farms,the estrus identification of sows,breeding work and artificial insemination are its core technologies.According to the actual situation of production and field work experience,the reproductive physiological characteristics of sows(initial estrus,sexual maturity,age-appropriate mating period,estrus cycle and estrus signs),Methods of identifying estrus of sows(external observation,static reflex test,boars test,vaginal mucous test),appropriate mating time,and application of artificial insemination technology were summarized in order to explore appropriate mating opportunities for sows with established estrus and improve their reproductive performance.The maximum increase of sow conception rate,birth rate,less empty loss rate,saving production costs,thereby increasing the large-scale pig farm breeding,economic benefits,production efficiency,to provide theoretical basis and technical support for its development.关键词
