摘要/Abstract

摘要： 试验选用147头体重约35 kg的健康大白猪随机分为3组，分别饲喂3种日粮，生长期（35～60 kg）和育肥期（60～100 kg）对照组分别饲喂粗蛋白质水平为16.4%和13.9%的玉米－豆粕型日粮；低蛋白质Ⅰ组分别饲喂粗蛋白质水平为15.4% 和13.0%日粮；低蛋白质Ⅱ组分别饲喂粗蛋白质水平为14.3%和11.6%日粮。试验猪舍平均温度16 ℃。试验结果表明，在低于临界温度的猪舍温度环境下，日粮蛋白质水平降低6%，对生长育肥猪的生长性能、饲料转化效率、背膘厚及每千克增重的饲料成本均无差异显著性影响（P>0.05）。因而，在冬季没有供暖的猪舍，考虑到降低日粮蛋白质带来的减少蛋白质饲料消耗、减少有害气体的排放和对环境的有利影响，日粮蛋白质水平降低6%是完全可行的。

Abstract: In this trial,a total of 147 large white pigs of average body weight 35 kg were randomly divided into three groups. The control group fed corn-soybean basal diet with crude protein level of 16.4%(35 to 60 kg) and 13.9%(60 to 100 kg),low protein I group were supplemented crude protein level of 15.4%(35 to 60 kg) and 13.0%(60 to 100 kg), and low protein Ⅱ group were supplemented crude protein level of 14.3%(35 to 60 kg) and 11.6%(60 to 100 kg).The average temperature of the pigpen was 16 ℃. The results showed that reducing 6% of dietary protein had no significant effects on daily gain,feed conversion,backfat and feed cost of gain at the present pigpen temperature（P>0.05）. So, considering the other beneficial effects of reducing protein feed consumption and harmful gas emissions, and the beneficial effect on environment in pigpen without heating in winter，reducing 6% of dietary protein is feasible in growing-finishing pigs raising.
