饲粮精粗比对反刍动物生产和经济效益的影响

Effect of concentrate to roughage ratio on ruminant production and economic benefit

适宜的饲粮精粗比可以提高反刍动物的生产性能,改善瘤胃发酵,调节肠道菌群平衡,提高免疫功能,改善屠宰性能和肉品质,提高养殖经济效益。为合理配制日粮,提高反刍动物养殖经济效益。文章综述饲粮精粗比对反刍动物生产性能、消化代谢、瘤胃发酵及菌群、屠宰性能、肉品质和产奶性能的作用,为提高反刍动.物养殖的效益提供参考。

The appropriate ratio of concentrate to roughage can improve the production performance of ruminants,improve rumen fermentation,regulate intestinal flora balance,improve immune function,improve slaughter performance and meat quality,and improve the economic benefits of breeding.In order to rationally prepare diets and improve the economic benefits of ruminant breeding,the paper reviewed the effect of concentrate to roughage ratio on ruminant production performance,digestion and metabolism,rumen fermentation and flora,slaughter performance,meat quality and milk production,so as to lay a reference for the improvement of ruminant breeding benefits.
