新型仔猪无抗饲料的初步开发研究

The research on new antimicrobial-free feed products of swine

选取经由微生物发酵的淀粉类能量饲料及发酵的豆粕原料,添加复合微生态制剂和灵芝免疫多糖,配制成无抗断奶仔猪饲料。以健康状况良好的25日龄断奶杜×长×大三元杂交仔猪作为试验仔猪,试验结果表明:试验组仔猪平均日增重318.8g,比对照组提高了3.44%;平均日采食量0.592kg,比对照组提高了5.83%;料重比方面,试验组的1.8569比对照组的1.8149略高;腹泻率方面,试验组的1.9097%比对照组的1.6493%高出15.79%;试验期间未出现仔猪死亡现象。试验所用无抗饲料产品经济效益比市场商品仔猪饲料略高,具备一定的技术可行性和经济可行性。

The free anti-weaning suckling pig feed is composed of soybean meal feed selected by the microbial fermentation of starch energy fermented,raw materials probiotics and immune Ganodemla lu- cidum polysaccharides. The test piglets,DurocxLandracexYordshire piglets weaned on day 25. The results show that： the experimental group of piglets gained 318.8 g daily average,which increased 3.44%, compared to the control group; while the average feed intake of 0.592 kg in the experimental group, which increased 5.83%, compared to the control group. About the material weight ratio,the test group gained slightly higher than the control group, l.856 9 to 1.814 9 and about the diarrhea rate,the result （1.909 7%）of the experimental group is higher（15.79%）than that（1.6493%） of control group, During these trial periods,there was no piglet death situation arising. In this study,we confirm that the cost-effective of antimicrobial-free feed products is slightly higher than merchandise suckling pig feed on the market and it possesses the technical and economic feasibility.
