摘要
本试验通过对不同时期牧草进行常规营养成分分析,探讨了载畜率与植物营养成分的关系。研究结果表明:粗蛋白含量随载畜率的增大而降低,中性洗涤纤维和酸性洗涤纤维含量随着载畜率的增大而增加,随着季节的变化先降低后增加,且在8月份最低,显著低于其他月份。
The relationship between stocking rate and plant nutrients in different seasons was discussed in this paper.The results showed as follows：plant crude protein declined and NDF and ADF increased with the increase of stocking rate,and NDF and ADF declined first,then increased late with season.NDF and ADF contents were lowest in August.
