现代化的羊产业应该利用优质种公羊,杂交改良本地的繁殖母羊,要想实现这一操作,繁殖母羊的发情鉴定的准确性及难易程度就尤为重要.繁殖母羊的发情鉴定最常用的方法是外部观察法和公羊试情布试情法,这种方式需要耗费大量人力和时间,不能随时随地发现母羊发情,往往错过最佳配种时间,给羊群的繁殖改良配种工作带来很多困难.根据多年工作经验,为解决繁殖母羊试情问题,现将繁殖母羊试情方式、方法进行总结,并对输精管结扎和阴茎移位术技术进行了技术创新.
For modern sheep industry,high-quality breeding rams should be utilized to crossbreed and improve local breeding ewes.To finish this idea,it is important for the accuracy and difficulty of estrus identification of breeding ewes.The most commonly methods for estrus identification in breeding ewes are external observation and male sheep estrus testing.These methods require much manpower and time,and cannot detect ewe estrus anytime and anywhere,which cause to often miss the optimal breeding time.These methods will bring many difficulties to the breeding and improvement of sheep flock.To solve the problem of reproductive ewe estrus testing,we summarized the ways and methods of reproductive ewe estrus testing,and innovated the techniques of via deferens ligation and penis transfer according to many years of work experience.
