摘　　要：本文就牧草细胞壁结构和组分,细胞壁降解过程和影响细胞壁瘤胃内降解的因素作一综述。影响细胞壁瘤胃内降解的因素主要有动物的饲喂方式、微生物、底物、瘤胃环境(pH、温度、离子种类和浓度)等。明确了瘤胃微生物对牧草的降解机制对合理利用牧草至关重要。The cell wall structure and composition, degradation progress and influencing factors on fiber degradation in rumen were reviewed in this paper. Factors affecting cell wall degradation are described including the feeding method, microorganism, substrates and ruminal environment （pH, temperature and presence of cations）. Identification of forage degradation mechanisms by rumen bacteria are most critical for efficient utilization of herbage.
