摘要
随着国民经济的发展和居民消费观念的升级,消费者对高蛋白质、低胆固醇的羊肉需求量日益增加。饲养模式会影响绵羊瘤胃发酵特征及微生物组成,进而影响绵羊的生长性能和肉品质。本文围绕全舍饲、自然放牧、放牧加补饲3种饲养模式对绵羊生长性能、屠宰性能、瘤胃发酵参数与微生物菌群的影响展开论述,阐释限时放牧加补饲提高肉羊生产水平和改善瘤胃发育的影响效应,以期为我国肉羊饲养技术改变与升级、生产性能与肉品质提升等提供有益参考。
With the development of the national economy and the upgrading of consumer attitudes,the demand for high protein and low cholesterol lamb by consumers is increasing day by day.The feeding mode will affect the rumen fermentation characteristics and microbial composition of sheep,thereby affecting their growth performance and meat quality.This article discusses the effects of three feeding modes,namely full house feeding,natural grazing,and grazing plus supplementary feeding,on the growth performance,slaughter performance,rumen fermentation parameters,and microbial community of sheep.It explains the effects of limited time grazing plus supplementary feeding on improving the production level and rumen development of meat sheep,in order to provide useful references for the transformation and upgrading of meat sheep breeding technology,production performance,and meat quality improvement in China.
