| 摘 要： | 牛对饲料中粗蛋白质的消化率，既受饲料的精粗比的影响，又受饲料质量的影响。牛粪尿对饲料中N的回收率与粗蛋白质的消化率呈极显著的负相关。建立草-牛-沼生态系统，有利于N素及其它营养元素的循环利用和再生能源的综合利用。

| Abstract: | Beef cattle's digestive rate of C.P. (crude protein) of the feed intake, was not only related to the ratio of concentrate to forage, but also to the qualities of the feed intake. The Nitrogen content in the excrement and urine was significantly negatively correlated with the digestible rate of the C.P. Establishment of a forage-beef cattle-biogas ecosystem would benefit the comprehensive utilization of the energy and the recycling utilization of many nutrients such as Nitrogen. |

| Keywords: | ecosystem cycling of Nitrogen digestible rate of C P biogas fermentation |
