The Effect Of Supplement Of Lysine On The Intake Digestion And Metabolism In Lambs

16 male lambs choosed and divided them to four groups(P>0.05) which ware 60 days old,during the days from 60th to 85th,feed them food containing Lys 8 g/kg,10 g/kg,12 g/kg和14 g/kg,and then observe their metabolism in different cases.The result showed that the lambs eat most when they were 60~85 days old and given the food containing 12g/kg Lys.The food they ate was 6% higher than those who eat food without Lys,and the weight increasing rate was 34% higher. It has an obvious influence to the effect of the feed stuff(P<0.05),and it also raised the digestion rate of dry material,energy,protein,fiber and half-fiber: 3.6%(P<0.05),3.3%(P<0.05),4.1%(P<0.05),7.5%(P<0.05),2.9%(P<0.05);But the effect to the digestion of Ca and P is not obvious. The forage was highest when the lambs are 120~145 days old and given the daily food containing Lys of 7 g/kg.
