杂交野猪适宜日粮磷水平与钙磷比例的研究

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)。

Proper requirement of dietary phosphorus levels and ratios of calcium to phosphorus in the crossbred wild boar

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).
