反刍动物饲粮精粗比应用研究进展

Research progress on application of concentrate to roughage ratio in ruminant diet

饲粮精粗比是科学饲喂反刍动物的基础,直接影响反刍动物的营养摄入、消化吸收和健康状况。合理的饲粮精粗比能够稳定反刍动物瘤胃内环境,改善瘤胃发酵,预防酸中毒,提高屠宰性能和泌乳性能,增加养殖经济效益。文章综述了不同精粗比饲粮对反刍动物的生长、血液等各项指标的影响,为选择适宜的反刍动物饲粮精粗比提供参考。

The concentrate to roughage ratio is the basis for scientific feeding practices of ruminants,which directly affects the nutritional intake,digestion and absorption,and health status of ruminants.A proper ratio of concentrate to roughage in the feed can stabilize the rumen environment,improve rumen fermentation,prevent acidosis,enhance meat and milk production,and increase the economic benefits of breeding.The article reviews the effects of different feed ratios on the growth,blood and other indicators of ruminant animals,to provide guidance on selecting appropriate feed ratios for ruminants.
