摘　　要：研究旨在探讨日粮中以酶解豆粕部分或完全替代鱼粉对断奶仔猪的诱食差异以及在教槽、保育不同阶段对仔猪生长性能的影响。试验一选取体重为(6.00±0.50)kg的三元断奶仔猪144头,按体重随机分为3组,即0鱼粉+20%酶解豆粕组、2%鱼粉+10%酶解豆粕组和4%鱼粉+0酶解豆粕组,分别与1%鱼粉+15%酶解豆粕日粮组(对照组)比较诱食性。试验二(大群试验,仅验证教槽阶段酶解豆粕替代鱼粉饲喂效果)选取平均体重(5.74±0.40)kg的三元断奶仔猪500头,按体重随机分为添加酶解豆粕的试验组和基础日粮对照组,进行为期10 d的饲养试验。试验三选取体重在(9.88±0.58)kg三元保育仔猪60头,随机分为添加酶解豆粕的试验组和基础日粮对照组,进行为期35 d的饲养试验。结果表明:利用酶解豆粕部分替代鱼粉可以改善教槽料适口性,极显著提高采食偏向性(P<0.01),仔猪生长性能指标(平均日增重、平均日采食量、料重比、腹泻率)及外貌性状(毛发评分,皮肤亮度、红度、黄度)方面均无显著差异(P>0.05),但添加酶解豆粕的试验组较对照组指标略有提升趋势:对体重在(5.74±0.40)kg教槽阶段仔猪,试验组平均日采食量为207.00 g,较对照组提高23.95%;试验组平均日增重为170.00 g,较对照组增加18.06%;(9.88±0.58)kg保育阶段仔猪,试验组平均日增重386.51 g,较对照组提高9.95 g;试验组平均日采食量646.31 g,较对照组提高9.84 g;试验组料重比1.67,较对照组降低0.02。综上所述,利用酶解豆粕部分或完全替代鱼粉不会对断奶仔猪的生长性能产生负面影响。The objective of this study was to evalute the effects of fishmeal(FM)replacement with en⁃zymatic soybean meal(ESBM)on palatability and growth performance of weaned piglets.A total of 144 weaned piglets with an average body weight of(6.00±0.50)kg were selected in exp.1.Pigs were ran⁃domly divided into three treatments,which were the 15%ESBM with no FM group,2%FM with 10%ESBM group and 4%FM with no ESBM group.Each treatment group was compared with the diets of 1%FM with 15%ESBM respectively.In exp.2,in order to verify the effect of enzymatic soybean meal replacing fish meal in the teaching trough stage,500 weaned piglets with an average body weight of(5.74±0.40)kg were randomly divided into two groups,which were ESBM group and FM group,for 10 days feeding experiment.In exp.3,a to⁃tal of 60 weaned piglets with an average body weight of(9.88±0.58)kg were randomly allocated to two treatments,which were ESBM group and FM group for 35 days feeding experiment.The results showed that partial substitution of fish meal with ESBM could significantly improve the feeding palatability(P<0.01),while there were no significant differences in growth performance,such as average daily gain(ADG),average daily feed intake(ADFI),feed conversion rate(F/G),diarrhea rate,and physical traits(coat quality score,skin color)of piglets(P>0.05).However,compared with FM group,the indexes of ESBM group showed a slightly improved trend:for(5.74±0.40)kg piglets,the ADFI of ESBM group was 207.00 g,23.95%higher than that of FM group,and the ADG of ESBM group was 170.00 g,18.06%higher than that of FM group.For(9.88±0.58)kg piglets,the ADG of the experimental group was 386.51 g,which was 9.95 g higher than that of the control group.The ADFI of experimental group was 646.31 g,which was 9.84 g higher than that of the control group.The F/G of the experimental group was 1.67,0.02 lower than that of control group.In conclusion,partial or complete substitution of fish meal with soybean meal do not play a negative effect on the growth performance o
