摘　　要：试验旨在探讨相同日粮条件下添加多生态复合益生素对仔猪生长及其育肥性能的影响。选取体质、年龄、健康程度相似的断奶仔猪杜洛克、约克夏和长白共1 1 0头和1 36头生长育肥猪,随机分为试验组和对照组;两组基础日粮一致,仔猪的试验组在基础日粮中添加0.35%多生态复合益生素,育肥试验组添加0.32%多生态复合益生素。断奶仔猪试验结果表明:试验组与对照组在试验中期体重、体长差异极显著(P<0.01),平均日增重增长了52.1 7%;末期时体重、体长差异极显著(P<0.01),平均日增重提高了20.93%。育肥猪试验结果表明:试验组与对照组在试验中期时体重、体长差异极显著(P<0.01);末期时体重、体长差异极显著(P<0.01),平均日增重提高了1 4.7%。表明,多生态复合益生素能减少仔猪死亡率、提高生长速度,并且提高育肥猪日增重、降低料重比、较大幅度减少异臭和苍蝇数量。Test is to explore the same diet, add more under the condition of ecological compound probiotics on piglets growth and its influence on the performance of the fattening. Select medical, age, health degree of weaning piglets similar distinctively, Yorkshire and 110 white head and 136 head growth fatten pigs, randomly divided into trial group and control group; Two groups of basal diet consistent, the group of piglets in basal diet added more than 0.35% ecological compound probiotics, add more than 0.32% group fattening ecological compound probiotics. Weaning piglets test results show that： in the test group and control group in the medium term weight, length difference is very significant（P〈0.01）, average daily gain increased 52.17%; In the end, the length difference weight very significant（P〈0.01）, average daily gain increased by 20.93%. Fatten pigs test results show that： in the test group and control group in the medium term weight, length difference is very significant（P〈0.01）; In the end, the length difference weight very significant（P〈0.01）, average daily gain increased by 14.7%. More than that ecological compound probiotics can reduce mortality piglets, improve the growth rate; And improve fatten pigs daily gain, reduce feed heavy than, a substantially reduced yixiu and flies quantity.
