【摘要】 本试验在AA肉鸡中将鸡沙门氏菌弱毒苗分别与两种不同的微生态制剂配合使用.结果表明.弱毒苗单独应用组、联合应用1组和2组的免疫保护效率分别为75%、90%和90%,均与攻毒对照组(40%)存在显著差异(P<0.05);攻毒20天后所有存活鸡细菌分离结果显示。上述3个试验组细菌分离分别为53.5%、55%和5.5%.也均与攻毒对照组(75%)存在显著性差异(P<0.05)。试验结果表明,该弱毒苗与某些微生态制剂联合应用的效果明显.具有较好的应用前景。更多还原

【Abstract】 AA broiler chickens were inoculated orally with attenuated S. gallinarum vaccin combined with two types of microecological agents respectively and challenged with virulent S. gallinarum and S. pullorum at?15 -day of age. The results showed that the protecitive efficacy of single vaccine using group, combined group 1, combined group 2 was 75%, 90% and 90% respectively and were significant different from the control group. After 35 - day of age the challenge strains were isolated from all of living chickens. The rates of isolation of three tested groups was 53. 5%, 55% , 5. 5% respectively and were significant different from the control group. It suggested that there was potential to develop a new bioproduct from the attenuated vaccine.更多还原
