舍饲因素对妊娠后期繁殖母羊生产性能影响研究

本项研究的目标是通过试验分析,找出舍饲条件中对繁殖母羊生产性能起主导作用的影响因素,并探索应对措施以指导生产。为此,笔者于2009年末开始在洮南市向阳乡开展了舍饲对母羊生产性能影响要素研究试验。结合我省西部的气候和饲料资源条件,总结试验结果,我们推荐在生产中使用代谢能8.50MJ/kg、粗蛋白9.50%、环境温度＋4℃、饲养密度0.8只/m2、环境湿度60%的参数,对妊娠后期繁殖母羊有较好的增产效果。

Raise Livestock in Late Pregnancy Reproductive Factors on the Production performance of ewes

This study's goal is to test analysis to identify breeding shed raising sheep on the production performance in a leading role in the influencing factors and to explore responses to guide the production.To this end,the author began in late 2009,Xiangyang Township in Taonan yard feeding on sheep conducted influential factors of production performance test.West of Hubei province and feed resources,climate conditions,summarize results,we recommend the use of metabolic energy in production 8.50 MJ/kg,crude prote...
