银杏叶提取物对肉仔鸡免疫器官指数及消化道局部体液免疫球蛋白含量的影响
Effects of Ginkgo biloba extract on immune organ index and content of immunoglobulins in local humor of digestive tract in broilers
摘要
Abstract
An experiment was conducted to investigate the modulatory effect of Ginkgo biloba extract (EGB) on immune organ index and the content of immunoglobulins in local humor of digestive tract in broilers. Three hundred and sixty one-day-old healthy Arbor Acres female broilers were divided into five groups, each with six replicates, and fed corn-soybean meal basal diet supplemented with 0, 0.15%, 0.20%, 0.25% EGB or 0.009% aureomycin for 42 days. The results showed that adding 0.20% EGB or 0.25% EGB to diet significantly improved spleen index, thymus index and bursa of Fabriocius index (P<0.05), increased the content of immunoglobulin IgA, IgG and IgM in bile and intestinal fluid of 42-day-old broilers (P<0.05) compared with the control and the aureo mycin. The study suggested that adding 0.20% EGB or 0.25% EGB to diets of broilers could promote immune organs development and improve local humoral immune response of digestive tract.关键词
