日粮钙水平对生茸期梅花鹿营养消化代谢的影响

采用 4个钙水平 ,研究生茸旺期 6岁雄性梅花鹿对营养物质消化代谢的影响。试验结果表明 ,4个日粮钙水平处理对能量、蛋白质、干物质、脂肪的消化率及能量、蛋白质的代谢率等指标的影响 ,各组间差异不显著 (P >0 0 5) ,日粮钙水平超过 0 74%时 ,不利于梅花鹿对营养物质的消化代谢 ,因此 ,在生产中不宜添加过多的钙饲料

Effects of Dietary Ca Levels on Digestion and Nutrients Metabolism in 6 year old Sika Deer of Antler growing stage

The results showed that the effect of the four diet disposals of Ca levels on the digestibility of energy,protein,dry matter,fat and the metabolic rate of energy,protein.There are not significant in each groups (P>0 05),the Ca levels of diet beyond 0 74%,it was unfavorable to the digestive metabolism of nutrients of sika deer.Therefore,it was inadvisable to add excessive Ca in production.
