饲料级蛋白酶对肉用仔猪生产性能的影响

摘要

ln this study, feed-grade proteinase was added into conventional diets of three-line crossbred (Duroc × Landrace × Large White) piglets, to investigate the effects of feed-grade proteinase on anti-diarrhea capacity, daily weight gain, feed in-take and feed conversion ratio of piglets. The results showed that adding feed-grade proteinase in diets enhanced anti-diarrhea capacity of piglets and improved signifi-cantly production performance and breeding efficiency of piglets. This study provided the reference for rational utilization of feed-grade proteinase in actual production.%该研究以杜长白三元杂交仔猪为供试材料，在常规日粮基础上添加饲料级蛋白酶，旨在探讨饲料中添加饲料级蛋白酶对仔猪抗腹泻能力、日增重、采食量和料肉比的影响。结果表明，日粮中添加饲料级蛋白酶能提高仔猪的抗腹泻能力，显著改善仔猪的生产性能及养殖效益。该研究为饲料级蛋白酶在实际生产中的合理利用提供参考依据。
