摘要
该文旨在评估肉用多羔快长新品系对普通湖羊在生长性状上的改造成果,通过对3、5、7月龄的本土缙云羊,庞大湖羊×缙云羊的杂交一代的体重、体长、胸围、管围进行测量,得出杂交对提高湖羊后代的生长性状的影响;杂交后代相较于本土羊在各方面都有所提升,各指数之间呈正相关.优质湖羊种羊进行杂交可以有效提高传统湖羊生长性能,为羊场带来更高的经济收益.
Abstract
The aim of this article is to evaluate the improvement of growth traits in ordinary Hu sheep by a new breed of meat based multi lamb fast growing sheep.By measuring the weight,body length,chest circumference,and tube circumference of the hybrid generation of local Jinyun sheep at three months old,five months old,and seven months old,as well as the large Hu sheep×Jinyun sheep,the impact of hybridization on improving the growth traits of Hu sheep offspring was obtained;Compared with local sheep,hybrid offspring have improved in various aspects,and there is a positive correlation between various indices.Hybridization of high-quality Hu sheep breeds can effectively improve the growth performance of traditional Hu sheep and bring higher economic benefits to the sheep farm.
