【摘要】 选用135头平均体重7.58±0.03kg的杜×长×大三元杂交断奶仔猪,采用3×3两因子试验设计,研究了饲料中添加3个复合菌制剂水平(0、0.1%、0.15%)和3个抗生素(金霉素+抗敌素)水平(0、0.1%+0.04%、0.15%+0.06%)对断奶仔猪粪中菌群和免疫功能的影响。试验共设9个处理,每个处理3个重复,每个重复5头。试验期28d。结果表明,单独或联合添加复合菌制剂和抗生素能显著提高断奶仔猪粪中乳酸杆菌和芽孢杆菌数量,显著降低粪中大肠杆菌数量。其中添加0.1%复合菌制剂和0.1%金霉素、0.04%抗敌素能显著提高断奶仔猪IgA、IgG、补体3和补体4水平。这表明,复合菌制剂和抗生素可不同程度上改善断奶仔猪的肠道菌群和提高断奶仔猪免疫功能,且两者存在互作效应。更多还原

【Abstract】 One hundred thirty five 28-day-old cross-bred（Duroc×Landrace×Yorkshire） weanled pigs with average weight（7.58±0.03） kg in a 3×3 crossing design trial were randomLy allotted into 9 groups.The experiment was conducted to investigate the effects of the preparation of Probiotics and antibiotics on growth performance of weaned piglets.The feeding trial lasted 28d.The results showed that suitable dietary probiotics and antibiotics level significantly improve feces in the number of Lactobacillus and Bacillus,significantly decrease the number of Escherichia coli.Feed added 0.1%the preparation of Probiotics and 0.1%) aureomycin and 0.04%colislin that had significant well than other groups（P<0.05） particularly on raise piglets IgA、IgG、C₃and C₄.The results indicated that the preparation of Probiotics and antibiotics can improving the intestine flora and improve the immune function of weaned piglets.Their interaction was appeared in the present study.更多还原
