摘　　要：本试验在中国北方典型草原地区冬春季节 ,用33只乌珠穆沁育成公羊测定不同环境温度下营养限制(能量、蛋白质限制)对于饲草料成分消化率的影响规律。通过对试验羊连续156次消化代谢试验的研究结果表明 :环境温度是独立于营养物质供给量而显著影响饲草料成分消化率的因素。粗纤维、中性洗涤纤维、酸性洗涤纤维、酸性洗涤木质素消化率随着营养限制持续时间而下降 ,当恢复到自由采食时消化率出现上升的趋势。This paper studied the digestibility of CF、NDF、ADF and ADL of Ujimqingrowing rams under different restriction condition in typical grassland of north China in cold season.Modeling of digestibility of CF、NDF、ADF and ADL in different nutrition restriction period was established on 156 metabolism trials.It shows that digestibility of CF、NDF、ADF、ADL were decreased during restriction period and the digestibility increased during compensation period.
