摘　　要：分30-60kgBW、60～100kgBW和30～100kgBW三个阶段研究了降低饲料中磷酸氢钙水平及降低磷酸氲钙的同时添加植酸酶对猪生长性能的影响。结果表明：磷酸氢钙添加水平在生长猪（30～60kgBW）饲料中由对照组的0．920％降低到0．552％、肥育猪（60-100kgBW）饲料中由对照组的0．760％降低到0．380％时都没有显著降低猪的生长性能（P〉0．05），降低磷酸氢钙的同时添加植酸酶虽没有显著提高猪的生长速度（P〉0．05），但能降低料肉比，其中在全阶段（30～100kgBW）的作用显著（P〈0．05）。This study was conducted by investigated the effects of decreasing the dicalcium phosphate level in feed and adding phytase to feed when the concentration of dicalcium phosphate were reduced on the performance of pigs which were 30-60kg BW, 60-100kg BW and 30-100kg BW respectively. The results showed that , when the levels of dicalcium phosphate were decreased from 0. 920% of control group to 0. 552% in growing pig （30-60kg） feed and from 0. 760% of control group to 0. 380% in finishing pig （60 --100kg） feed, pigs＇ performance were not significantly reduced （P〉0.05）. Addtion of phytase didn＇t improve the growth rate of pigs significantly （P〉0.05） but reduced the the ratio of feed to gain, and the effects were significant during the phase of 30-100keg BW （P〈0.05）.
