| 摘 要： | 选择30头24.4kg左右的健康杜×长×大杂交猪,将其随机分成2组,每组3个重复,每个重复5头猪,分别饲喂两种日粮：对照组日粮（18.4%CP＋0.37%有效磷,高蛋白高磷组日粮）和试验组日粮（16.0%CP＋0.28%有效磷＋100g/t植酸酶,低蛋白低磷加酶组日粮）,研究低蛋白低磷加酶日粮对生长猪生产性能及减排效果的影响。结果表明,低蛋白低磷加酶日粮对生长猪生产性能没有显著影响,但是可显著提高氮、磷的利用率,从而减少氮、磷排放。

| Abstract: | Thirty DLY pigs with an initial body weight of about 24.4 kg were randomly divided into two groups, three replicates for each treatment, five pigs for each replicates, which were fed two different diets （Control group with 18.4% CP and 0.37% available phosphorus, treatment group with 16.0% CP, 0.28% available phosphorus and 100g/t phytase）. The purpose of the experiment was to study the effect of treatment group＇s diet on the performance and emission reduction of DLY growing pigs. The results suggested that the treatment feed had on significant effect on the production performance of growing pigs, but it could significantly reduce nitrogen and phosphorus from feces and urine bv increasing the utilization rata_ |
