| 摘 要： | 用三头安装瘤胃瘘管的成年牛，采用半体内法(in．situ)研究奶牛日粮中常用的饲料在瘤胃不同时间点的降解率和动态降解率，试验得出32种饲料粗蛋白质2h、6h、12h、24h、36h、48h、72h瘤胃降解率和相关参数，为奶牛日粮配制提供依据。

| Abstract: | Three rumen-fistulated steers were used to investigate in situ degrada tion characteristics of crude protein in feedstuffs for dairy cow. The results w ere as follows: plant protein feedstuffs: peanut meal>soy bean meal>sunflower me al>rape seed meal>cottonseed meal>flax meal; cereal feeds: barley>wheat>sorghum> corn>millet; grasses: alfalfa>autumnal grass>chinese wildrye; crop straws: corn silage>corn straw>soystraw>wheat straw>cotton straw>rice straw. |
