摘要: 试验选择90头初始体重20~30 kg的长×大二元杂交猪,随机分为5个处理(4个试验组和1个对照组),每个处理3个重复,每个重复6头猪,公母各占一半,研究低磷加植酸酶日粮不同钙磷比对生长猪生长性能和血液指标的影响。结果表明:钙总磷比值在1.4~1.0:1时,生长猪的生产性能效果最好,日增重、日采食量分别比对照组提高8.4%,10.8%,统计分析差异显著(P<0.05);钙总磷比为1.4:1时血清学指标最佳。

Abstract: 90 pigs (Large white×Landrace) weighed 20-30.0 kg (barrow:gilt=1:1) were allotted randomly into 5 treatments with 3 replicates per treatment and 6 pigs per replicate to study the effects of different calcium-phosphorus ratio in diets with low phosphorus level and added phytase on the growth performance and serum biochemical indices of growing swines. The results showed that the performances of growing swine were the best when calcium is 1.4-1.0:1, the ADG and ADFI increased by 8.4% and 10.8%, respectively, compared with control group (P<0.05). The serum biochemical indices indicated that the best calcium-phosphorus ratio was 1.4:1.

Key words: Corn-soybean meal-fish meal diet, Growing swine, Phytase, Calcium to phosphorus ratio, Performance, serum index
