Abstract

This experiment was conducted study the effects of feeding ammoniated cottonseed hull on ruminal environment indexes and serum urea nitrogen content of Tarim red deer, and hope to provide a theoretical basis for ammoniated feed rational use of Tarim red deer. A paired experimental design (feeding ammoniated cottonseed hull before and after feeding ammoniated cottonseed hull) was used, and three Tarim red deer fitted with permanent rumen fistula were chosen as experimental animals. The experiment divided into 2 periods, and each period had a 7-day pretrial period plus a 15-day trial period. The Tarim red deer in prophase were fed a diet with 1 kg un-ammoniated cottonseed hull, and those in anaphase were fed a diet using ammoniated cottonseed hull to replace un-ammoniated cottonseed hull. The results showed as follows:after feeding ammoniated cottonseed hull, ruminal fluid pH, ammonia nitrogen concentration, microbial protein content and serum urea nitrogen content of Tarim red deer were significantly or extremely significantly increased compared with feeding ammoniated cottonseed hull before (P < 0.05 or P < 0.01), while the concentrations of ruminal fluid acetate, butyrate and total volatile fatty acids (VFA) were significantly decreased compared with feeding ammoniated cottonseed hull before (P < 0.05 or P < 0.01). The feed cost of Tarim red deer before and after feeding ammoniated cottonseed hull were 5.55 and 5.04 RMB/(head·d), respectively, and the cost was reduced 0.51 RMB/(head·d). Thus, Tarim red deer on ammoniated cottonseed shell has a strong ability to adapt, the application of ammoniated cottonseed shell in the diet of Tarim red deer can effectively save protein feed, improve the utilization efficiency of forage and increase economic efficiency.

Key words： Tarim red deer; ammoniated cottonseed hull; ruminal environment; microbial protein; serum urea nitrogen
