摘　　要：选用纯种野公猪与杜洛克母猪的杂交后代含50%野猪血缘的42日龄杂交野猪36头,随机分成9组,试验为双因子3水平(3×3)析因安排分组,完全随机区组设计,每个因子3个水平,共9个处理。结果显示,不同磷水平与钙磷比例对各处理组的平均日耗料量、平均日增重、料重比差异均不显著(P>0.05)。不同钙磷比例水平下对血清钙的影响差异极显著(P<0.01),日粮磷和钙磷比例互作效应对血清钙影响差异极显著(P<0.01)。不同日粮钙磷比例对血清磷水平差异显著(P<0.05),日粮磷和钙磷比例互作效应对血清磷影响显著(P<0.05);0.4%的日粮磷水平与0.6%的磷水平对血清AKP活性影响差异极显著(P<0.01)。The wild boars of 42days old which contain 50% consanguinity and crossbred by duroc were selected and a 2 × 3 factorial design was used in the current experiment. Thirty-six wild boars were assigned randomly into 9 groups. The results showed that the level of phosphorus and calcium to phosphorus ratio did not affect the ADFI, ADG and FCE significantly （ P 〉 0. 05）. Dietary calcium to phosphorus ratio affected serum calcium levels significantly （ P 〈 0.01 ）. There was obvious interaction of phosphorus levels and calcium to phosphorus ratio on serum calcium level （P 〈0. 01 ）. Different dietary calcium to phosphorus ratio affected the serum phosphorus level significantly （P 〈 0. 05 ）. There was obvious interaction of phosphorus levels and calcium to phosphorus ratio in serum phosphorus levels （ P 〈 0. 05 ）. Significant difference was also found in the activity of serum AKP between the two groups （0. 4% phosphorus level and 0. 6% phosphorus level） （P〈0.01）.
