Effect of Tricin on Immunological Indicators of AA Broiler
摘要
Abstract
In order to investigate the effect of tricin on immunological indicators of AA broiler, a total of 120 AA broilers were selected and randomly divided into four groups. The control group was fed with basal diet. The basal diet of experimental groupⅠ,ⅡandⅢwere supplemented with 150, 300 and 450 mg/kg tricin, respectively. Ten broilers were chosen from each group in 28th, 35th and 42th d to determine their serum globulin content. Meanwhile, the bursa of Fabricius and spleen of the selected broilers were collected and weighed to calculate their immune organs index, and the proliferation ability of T and B lymphocyte were determined by using MTT colorimetry. The results showed that the index of bursa of Fabricius of AA broilers were significantly increased when they were fed with the basal diet supplemented with 300 mg/kg of tricin for 28 d (P<0.05). The serum globulin level and immune organs index of AA broilers were significantly increased when they were fed with the basal diet supplemented with 450 mg/kg of tricin for 28 d (P<0.05). The serum globulin level, immune organs index and the proliferation ability of B lymphocyte of AA broilers were significantly increased when they were fed with the basal diet supplemented with 300 mg/kg of tricin for 35 d (P<0.05). The serum globulin level, spleen index and the proliferation ability of T and B lymphocyte of AA broilers were significantly increased when they were fed with the basal diet supplemented with 450 mg/kg of tricin for 35 d (P<0.05 or P<0.01). The index of bursa of Fabricius of AA broilers were significantly increased when they were fed with the basal diet supplemented with 300 and 450 mg/kg of tricin for 42 d (P<0.01), respectively. The proliferation ability of B lymphocyte of AA broilers were significantly increased when they were fed with the basal diet supplemented with 450 mg/kg of tricin for 42 d (P<0.05). It was indicated that a series of immunological indicators of AA broiler were increased when they were fed with the basal diet supplemented with tricin, and the optimum adding quantity was 450 mg/kg.关键词
