摘　　要：试验旨在研究日粮不同表观可消化磷(ATTD P,可消化磷)水平对生长育肥猪生长性能的影响。选用平均体重(40.13±2.34)kg的生长育肥猪784头,按体重随机分为4个处理组,每个处理组7个重复,每个重复28头猪。4个处理组分别饲喂可消化磷水平为0.25%、0.30%、0.35%、0.40%的日粮。结果表明:①在试验第1阶段和整个试验期,0.25%组和0.30%组生长育肥猪平均日增重显著高于0.35%组(P<0.05);②在试验结束时,0.35%组和0.40%组3分毛况的生长育肥猪占比显著高于0.25%组(P<0.05);③0.25%组整个阶段(40~105 kg BW)的造肉成本比其他各组低0.05~0.12元/kg(0.9%~2.0%)(P>0.05)。因此,从生长性能方面考虑,0.25%和0.30%可消化磷水平的日粮饲喂效果较好;仅看造肉成本,0.25%可消化磷水平的日粮最低;但饲喂0.35%和0.40%可消化磷水平日粮的猪只毛况要好于饲喂0.25%可消化磷水平日粮的猪只。This study investigated the effects of different apparent total tract digestible(ATTD)phosphorus levels on the growth performance and health status of growing-finishing pigs.A total of 784 growing pigs with the average body weight of(40.13±2.34)kg were randomly allocated to four treatments with sev⁃en replicates per treatment and 28 pigs per replicate.Four treatments were fed with 0.25%,0.30%,0.35%and 0.40%ATTD phosphorus level diet,respectively.The results showed that:①During the first period and the whole,the pigs of 0.25%and 0.30%ATTD phosphorus groups had higher average daily gain weight compared with that of 0.35%group(P<0.05);②At the end of the study,pigs of 0.35%and 0.40%ATTD phosphorus groups had better fur score compared with that of 0.25%group;③Also,0.25%ATTD phosphorus group cost the least per kilogram of pork production.In conclusion,0.25%and 0.30%ATTD phosphorus groups had better growth performance,and 0.25%group was comparatively cost-optimal.However,0.35%and 0.4%ATTD phosphorus groups had better fur score.
