Effect of RPlys on digestive metabolism of nitrogen in sheep.

[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.
