芦荟多糖对黄羽肉鸡血液生化指标的影响

摘要

为了观察芦荟多糖(Aloe polysaccharide,AP)在改善和增强肉鸡的免疫促作用时对肉鸡血液生化指标的影响,在接种新城疫(Newcastle disease,ND)疫苗的同时颈部皮下注射AP溶液(AP实际注射剂量分别为每次3.75,7.50,11.25,15.00,0 mg·只-1),就AP不同质量浓度及其注射次数对肉鸡血液生化指标的影响进行了研究.结果表明,除个别处理和个别指标外,一定质量浓度的AP溶液1次或2次处理肉鸡的血液生化指标与对照相比差异不显著(P＞0.05),同时在一定程度上可降低肉鸡血清甘油三酯和总胆固醇的含量,且除个别处理外与对照相比差异显著(P＜0.05).由此表明,一定质量浓度的AP溶液对ND疫苗免疫肉鸡的血液生化指标无任何不良影响,可以作为免疫促进剂与ND灭活疫苗配伍使用,或在接种ND活疫苗时使用.%To observe the effect of aloe polysaccharide ( AP) on blood bio-chemical parameters of yellow-feathered broilers (broilers) in improving and enhancing the immune efficacy, AP solution was injected subcutaneously in amount of 3. 75 ,7. 50 ,11. 25 ,15. 00 ,0 mg each time per bird, respectively, while Newcastle disease ( ND) vaccines were inoculated, and effects of AP of different concentrations and injecting times on blood bio-chemical parameters of broilers were studied. The results showed that the blood bio-chemical parameters of broilers injected once or twice with AP of certain concentration were not significantly different compared with the control (P >0.05). AP solution of certain amount could reduce the content of triglyceride and total cholesterol in blood of broilers to some extent, and was significantly differenct compared with the control(P <0.05) ,except individual treatment and parameters. It was proved that certain amount of AP had no unfavorable effects on the blood bio-chemical parameters of broilers, and could be used as an immunopotentiator to use safely with ND vaccine simultaneously.
