摘　　要：将低蛋白、低铜、低锌生态饲料添加到杜梅商品猪日粮中,探索符合杜梅猪品种特点和营养需要的绿色无抗专用饲料。选取平均体重在20 kg左右的杜梅商品仔猪120头,随机分为试验组和对照组,研究低蛋白、低铜、低锌饲料对杜梅商品猪生长性能的影响。结果表明,试验组和对照组中都有猪发病与死亡。与对照组相比,试验组全程平均日增重和全程平均饲料转化率均较好,但2组间所有生长性能均无显著差异(P>0.05)。与对照组相比,试验组2个生长阶段猪粪便中氮、锌的含量均显著下降(P<0.05)。In this experiment,the ecological feed with low protein,low copper and low zinc was applied in the diet of Duroc×Meishan commercial pigs,the green,non-resistant and special feed in line with the characteristics and nutritional needs of Duroc×Meishan pigs were explored.A total of 120 Duroc×Meishan piglets(average body weight of about 20 kg)were randomly divided into experimental group and control group.The effects of the diet with low protein,low copper,low zinc on the growth performance of Duroc×Meishan commercial pigs were studied.The results showed that there were morbidity and death of pigs in experimental group and control group.Compared with the control group,the average daily gain and feed conversion ratio in the whole process of experimental group were slightly better,but there was no significant difference in all growth performance indices between the two groups(P>0.05).Compared with the control group,the contents of nitrogen and zinc in pig feces in experimental group in two growth stages significantly decreased(P<0.05).
