Abstract

Abstract: The effective utilization of forage and control of methane emission from grazing sheep could be influenced by the changes of grassland community structure and nutrient composition of forages.The aims of this experiment,conducted in the Xilingol grassland,were to study the effect of ingredient and quality of forages on rumen fermentation,nutritional degradability and CH₄ emission.

Key words: Sheep, Digestion and metabolism, Seasonal influence, CH₄ emission, Additive, Inner Mongolia Steppe

摘要： 随着草原群落组成及其营养特性的变化,放牧家畜对牧草的利用率和甲烷气体排放量也随之发生变化。本研究对锡林郭勒草原的牧草种类组成和品质的变化及其对绵羊瘤胃的消化代谢以及甲烷气体排放的影响进行研究。
