选择"杜×长×大"三元杂交生长猪54头,研究了大肠杆菌、黑曲霉来源植酸酶替代日粮中部分磷酸氢钙对生长育肥猪生长性能、养分消化率、血液生化指标及粪磷、氮排泄的影响。试验猪随机分成对照组、试验Ⅰ组、试验Ⅱ组,每组3个重复。对照组饲喂常规日粮,试验Ⅰ组饲喂低磷+植酸酶Ⅰ的日粮,试验Ⅱ组饲喂低磷+植酸酶Ⅱ的日粮。试验结果表明,在生长育肥猪日粮中添加植酸酶替代部分磷酸氢钙,改善了生长育肥猪生长性能,其中添加大肠杆菌植酸酶显著改善生长育肥猪的生长性能;显著改善了干物质、粗蛋白质、钙、磷、总能的表观消化率,并显著降低了粪中氮、磷的排泄;显著提高了血清中总蛋白、球蛋白、血清磷的...

In this experiment fifty-four growing pigs were conducted to study the effects of Escherichia coli phytase and Aspergillus niger phytase substitute Calcium phosphate in diet on the growth performance,nutrient utilization,serum biochemical parameters and excretion of feces P and N for growing-finishing pigs.There were 3 treatments with control group,experiment groupⅠ,experiment groupⅡ,and normal diet was fed to control group,low-P diet adding phytaseⅠwas fed to experiment groupⅠ,low-P with adding phytaseⅡwas fed to experiment groupⅡ.Each t...
