摘　　要：选用48头体重相近,体质健康的三元杂交(杜×长×大)仔猪为试验动物,随机分为2组,每组3个重复,每个重复8头,对照组为正常磷酸氢钙水平日粮,实验组日粮中添加5000 U/g植酸酶100 g/t替代50%磷酸氢钙。试验结果表明:在饲料中添加5000 U/g的植酸酶,能够使猪的日增重较对照组提高8．85%(P＜0．05),日采食量较对照组提高3．42%,饲料转化效率提高5．08%;钙、磷的表观消化率分别提高了14．29%(P＜0．05)、18．83%(P＜0．05),对粗蛋白质的表观消化率影响不大;添加植酸酶后粪中钙的排出减少21．05%(P＜0．01),粪中磷的排出减少17．91%(P＜0．01);骨中的钙、磷变化不大,全血中的钙提高了9．30%,磷提高了17．91%(P＜0．01);血清中钙提高12．62%,磷提高了7．08%。Forty-eight near avoirdupois and healty swine （Duroc × Landrace × Da） were randomly divided into two groups as experiment which were supplemented phytase100 g/t（5 000 U/g） and control which were supplemented 50 % CaHPO4. the result showed that by added Phytase daily gain, daily feed intake, feed transition rate, Calcium and Phosphorus of Apparent Digesibility, Calcium and Phosphorus of Blood, Calcium and Phosphorus of serum increased 8.85%（P〈0.05）, 3.42%,5.08%,14.29% （P〈0.05）,lS. 83%（P〈0.05）, 9.30%,17.91%（P〈0.01）, 12.62%, 7.08% respectively; and Calcium and Phosphorus of faces discharged 21.05% （P〈0.01）, 17.91% （P〈0.01）respectively, but without influence for crude protein and Calcium and Phosphorus of bone.
