摘要
该试验旨在研究采用非常规饲料原料替代豆粕制成的低蛋白、低豆粕日粮对生长猪生产性能及经济效益的影响。试验选用36 kg左右的健康杜长大三元杂生长猪360头,随机分成4组,每组6个重复,每个重复15头猪,对照组A饲喂正常蛋白水平的高豆粕日粮(CP17.0),试验组B饲喂低蛋白水平的高豆粕日粮(CP15.0),试验组C饲喂低蛋白水平的低豆粕日粮(CP15.0),试验组D饲喂低蛋白水平的低豆粕+复合酶制剂日粮(CP15.0),试验期为30天。试验结果表明:低蛋白低豆粕日粮,不影响生长猪的平均日增重、平均日采食量、料重比(P>0.05)。每千克体重增重成本以低蛋白低豆粕+复合酶的试验D组最佳,比正常日粮对照组A低0.49元/千克。
The aim of this experiment is to investigate the effects of low protein and low soybean meal diets on the production performance and economic benefits of growing pigs.360 healthy Duroc growing pigs weighing around 36 kilograms were selected for the experiment and randomly divided into 4 groups,with 6 replicates in each group and 15 pigs in each replicate.Control group A was fed normal diet with high soybean meal(CP 17.0%).Group B was fed low protein diet with high soybean meal(CP 15.0%).Group C was fed low protein diet with low soybean meal(CP 15.0%),and group D was fed low protein diet adding compound enzymes with low soybean meal(CP 15.0%).The experimental period was 30 days.The experimental results indicate that:A low protein and low soybean meal diet had no significant effect on the average daily weight gain,average daily feed intake,and feed to weight ratio of growing pigs(P>0.05).The cost of weight gain per kilogram of body weight is best in the group D with low protein and low soybean meal and compound enzymes,which is 0.49 yuan/kg lower than the normal diet control group A.
