摘要: 挑选体重相近,健康的40只1岁自繁猕猴。按日粮钙和磷水平,将试验猴随机分为A、B两个组,再根据钙磷比1.2:1、1.4:1、1.6:1、1.8:1和2.0:1,将A、B各分为5个处理组,即A1、A2、A3、A4、A5和B1、B2、B3、B4、B5,每个处理组4只试验猴,雌雄搭配,单笼饲养。各处理组日粮的钙、磷水平和钙磷比用饲料级CaCO3、CaHPO4和分析纯NaH2PO4调配。试验结果表明,A组在1.6%钙水平下钙磷比对生长期实验猕猴钙、磷利用率的影响不显著(P>0.05);B组在0.98%磷水平下,B1处理组钙、磷利用率显著高于其余4个处理组(P<0.01。实验结果表明,生长期猕猴日粮在0.89%磷水平下,最适钙磷比是1.2:1,并且日粮钙、磷水平和钙磷比对钙、磷利用率具有互作效应。

Abstract: Forty healthy growing laboratory rhesus monkeys were randomly divided into A and B group. According to calcium to phosphorus ratio (1.2:1,1.4:1,1.6:1,1.8:1 and 2.0:1) each group was divided into five groups (A1,A2,A3,A4,A5 and B1,B2,B3,B4,B5 respectively),including 2 male and 2 female in each. The level of dietary calcium or phosphorus and calcium to phosphorus ratio were adjusted by CaCO3, CaHP03 and NaH2PO4. The result showed, that no effect of calcium to phosphorus ratio on its utilization in growing laboratory rhesus monkeys were observed in A groups (P>0.05). Calcium and phosphorus utilization of B1 group were the highest in B groups (P<0.01). The results suggested that the calcium to phosphorus ratio 1.2:1 with phosphorus level 0.89% in dietary was the best choice for calcium and phosphorus utilization in growing laboratory rhesus monkeys.
