高山草原绵羊放牧生态及消化代谢系列研究Ⅲ。放牧绵羊食入牧草消化率动态及其限制性因素分析
A serial study of grazing ecology and digestibility and metabolism of sheep on alpine pasture Ⅲ The analysis of seasonal dynamics and the restrictive factors of the diet digestibility by grazing sheep
摘要
Abstract
The seasonal dynamics of in vitro dry matter digestibility of esophageal fistula Samples by grazing sheep on alpine pasture were studied. The results showed that the digestibility were 61.00±1.96%, 58. 84±1.93%, 51.40±0.84% and 40. 58+1.13% in July, August, October and January, respectively. The relative humility, crude protein and nitrogen-free extract were the main restrictive factors to affect the digestibility by using grey system analysis method.关键词
