甘露寡糖和有机硒联合应用对肉鸡生产性能与免疫性能的影响

Effect of Mannano Ligosaccharide and Organic Selenium on Production Performance and Immune Function of Broilers

为了分析甘露寡糖和有机硒联合添加对肉鸡生产性能、屠宰性能及免疫性能的影响,试验通过肉鸡日粮中单独或联合添加金霉素、甘露寡糖、有机硒进行试验。结果显示:金霉素添加组42日龄肉鸡的活体重显著高于基础日粮组(P<0.05),但屠宰率显著降低(P<0.05);甘露寡糖和有机硒联合添加能够提高肉鸡生产性能与屠宰性能的各项指标(P>0.05),甘露寡糖和有机硒联合添加可提高免疫器官指数(P>0.05)。与基础日粮组和金霉素添加组相比,甘露寡糖和有机硒联合添加肉鸡血液Ig A和IL-2的含量显著升高(P<0.05)。表明甘露寡糖和有机硒联合添加能够提高肉鸡生产性能及免疫性能,可以应用于无抗饲料的研发。

In order to analyze the effect of oligosaccharide combined with organic selenium on production performance and immune function of broilers, the test was conducted by feeding chlortetracycline, mannooligosaccharides, organic selenium alone or in combination to the broiler diets. The results showed that the live weight of 42-day-age broilers fed chlortetracycline group was significantly higher than that of the basal diet group（P〈0.05）, but the slaughter rate was significantly lower（P〉0.05）. The combination of mannose-oligosaccharide and organic selenium could improve production performance and slaughter performance of broilers（P〈0.05）. The combination of mannose-oligosaccharide and organic selenium could increase the immune organ index. Compared with the basal diet group and the chlortetracycline group, the contents of Ig A and IL-2 in the blood of were significantly increased after mannose-oligosaccharide and organic selenium supplementation（P〈0.05）. In conclusion, the combination of mannose-oligosaccharide and organic selenium could improve production performance and immune function, and could be applied to the research and development of non-resistant feed of broilers.
