酵母蛋白替代进口鱼粉对断奶仔猪 生产性能的影响

试验将60头28日龄断奶的健康、体重相近（7.63μ0.52kg）的长大二元杂交商品仔猪按体重、性别，随机分为5组，即对照组和4个试验组，对照组即原用进口鱼粉配方组，第1、2、3、4试验组为分别用山东济宁圣齐生物生物工程生产的活性酵母蛋白粉替代25%、50%、75%和100%的进口鱼粉组，共试验4w。研究添加不同水平酵母蛋白粉对断奶仔猪生产性能的影响。结果表明：断奶仔猪日粮中添加酵母蛋白替代进口鱼粉后均没有显著改变原添加进口鱼粉仔猪断奶后0~4w的平均日采食量和平均日增重，饲喂效果较好。综合各项试验指标，酵母蛋白粉以50%~75%的比例替代进口鱼粉，添加到断奶仔猪日粮中对仔猪生产性能有明显的促进作用，且饲料成本下降。

Yeast Protein to Replace Imported Fish Meal Weaned Piglets Performance of the Test Report

This test will be weaned 60 of the 28-day-old health and weight similar (7.63μ0.52kg) of goods grew up dual hybrid piglets by weight, sex, were divided into five groups. That is, the control group and four test group, which controls imports of fish meal with the original formula group, 1, 2, 3, 4 were used for the test group’s Shandong Jining-production of bio-engineering activity of yeast protein flour substitute 25%, 50 %, 75% and 100% of the imports of fish meal, of a total test four weeks. Add yeast on different levels of protein powder on weaning performance of piglets. The results showed that: Weaned piglets effect of yeast protein replace imported fish meal after no significant changes in the original add fish meal imports after the piglets weaned from 0 to four weeks, the average intake and average daily gain, feeding effective. The comprehensive test indicators, yeast protein powder to 50~75 percent of imported fish meal replacement, added to the diet of piglets weaned piglets performance marked role in promoting and feed costs decline.
