稀土添加技术在绵羊舍饲养殖中的应用研究

Application of Rare Earth Supplementation Technology in Barn Feeding in Sheep

在绵羊的舍饲过程中,不同的饲料添加剂会影响其生产性能。近年来的研究表明,稀土元素添加到饲料中,可以使舍饲绵羊在产肉率、产羔率、饲料转化率、肉品质、毛长度和抗病性能方面有不同程度地提高。就稀土饲料添加剂对舍饲绵羊体重增加影响的研究进展进行了综述。

In the barn feeding process of sheep,different feed additives will affect their performance.Recent studies show that the rare earth elements added to the feed can increase meat production rate,lambing rate,feed conversion ratio,meat quality,wool length and disease-resistance at varying degrees in sheep reared in barn.The paper reviews the research progress in the effects of rare earth element used as feed additive on daily gain in sheep reared in barn.
