饲粮不同能量、蛋白质水平对生茸期梅花鹿的影响

Effects of Different Levels of Dietary Energy on the Yearling Sika Deer During the Antler Growth Period

本研究采用 2 (CP:2 4和 2 2 % )× 2 (GE:4.1 5和 1 6.74MJ/kg)二因子交叉设计 ,选用1岁 (毛桃 )梅花公鹿 69头 ,分为四个试验组 ,进行了饲养试验和消化试验。试验结果表明 ,饲粮能量、蛋白质水平对鹿体增重的互作效应显著 (P<0 .0 5) ,饲粮粗蛋白质水平对蛋白质消化率有极显著的影响 (P<0 .0 1 )。 1岁梅花鹿生茸期饲粮中能量、蛋白质适宜水平分别为1 7.37MJ/kg GE、2 2 .44% CP。平均每头鹿每天对能量和蛋白质的需要量分别为 36.84MJGE和 478g

The 69male deers were randomly assigned to 4 groups.The re- sults showed that the deer liveweight gains were significantly influenced by the interaction between dietary energy and protein( P<0 .0 5) .The apparent di- gestibility of crude protein increased with increasing dietary protein level.The optimal dietary energy concentration and crude protein level were1 7.37MJ/ kg GE and2 2 .4 4 % CP respectively.The daily requirements of energy and crude protein per deer were37.0 0 MJGE and4 78g CP respectively during the antler growth period for yearling sika deer.
