Abstract: Twenty-seven Inner Mongolia white cashmere goats with permanent rumen fistula and duodenal cannulas were randomly divided into three groups in each on the basis of body weight. The three groups as follows: low nitrogen group(CP:10.5%),low nitrogen +NCG group(CP:10.5%) and medium nitrogen group(CP:13.5%). The effects of different protein levels on the degradation parameters of rumen and quantities of rumen starch were studied. The results showed that: With decreasing addition of protein, the intake of dietary starch were increased, and the total tract starch digestibility of low nitrogen and low nitrogen + NCG group were significantly higher than medium nitrogen group. According the results of Wang Ling, Ren Ying and Han Fei, the glucose content infused in duodenum of goats were determined by 0, 20 and 40 g/d. The effects of dietary protein levels and glucose levels with addition of NCG on the digestive and metabolism of the cashmere goats were assessed. Further results showed that: The apparent digestibility of total digestive tract increased with the decrease of protein level in diet protein.. At the same protein level,increasing the rumen glucose and the addition of NCG had no significant effect on the digestibility of DMD, NDFD and SD.
