| 摘 要： | [目的]研究包被赖氨酸对绵羊氮消化代谢的影响。[方法]采用单因子试验设计,设3个处理组：A组（对照组,只饲喂基础饲粮）;B组（赖氨酸组,在基础饲粮的基础上,每天每只羊通过瘤胃投饲4 g赖氨酸盐酸盐）;C组[包被赖氨酸组,在基础饲粮的基础上,每天每只羊通过瘤胃投饲7.4 g包被赖氨酸（赖氨酸含量为4 g）],采用全收粪法和全收尿法进行消化代谢试验。定时采集饲料样、粪样、尿样和瘤胃液,研究包被赖氨酸（RPlys）对绵羊体内氮存留的贡献。[结果]向试羊日粮中添加RPlys后,干物质进食量、干物质消化率、进食氮、粪氮排出量各组间差异均不显著,RPlys的添加降低了绵羊尿氮排出（P〈0.05）,对粪氮排出无显著影响（P〉0.05）,提高了氮沉积率（P〈0.05）。[结论]RPlys的添加有利于氮在绵羊体内的沉积。

| Abstract: | [Objective] The aim was to study the effect of RPlys on digestive metabolism of nitrogen in sheep.[Method] The contribution of RPlys for nitrogen residual in sheep was researched by digestive metabolism test.[Result] The results showed that adding RPlys decreased excretion of urine nitrogen （P0.05） and had no significant effect on excretion of fecal nitrogen （P0.05）,and precipitation coefficient of nitrogen was increased （P0.05）.[Conclusion] RPlys is propitious to the aggradations of nitrogen in sheep. |
