Effect of Fagopyrum dibotrys (D.Don) Hara on Growth Performance, Immune Function and Intestinal Structure of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of Fagopyrum dibotrys (D.Don) Hara on growth performance,immune function and intestinal structure of broilers.A total of 270 one-day-old healthy Tiejiaoma broilers were chosen and randomly divided into 3 groups with 6 replicates per group and 15 broilers per replicate.Control group was fed with the basal diet,group Ⅱ was fed with basal diet adding 8％ flavomycin 60 mg/kg + 15％ aureomycin 270 mg/kg and group Ⅲ was fed with basal diet adding 1％ Fagopyrum dibotrys (D.Don) Hara.The trial period lasted for 21 days.The results showed as follow:① At 21 days of age,the average daily feed intake of group Ⅲ was significantly lower than that of groups Ⅰ and Ⅱ (P＜0.05).However,there was no significant difference in the average daily gain and F/G among the three groups (P＞0.05).②At 21 days of age,the thymus and bursa of Fabricius indexes of groups Ⅱ and Ⅲ were significantly higher than that of group Ⅰ (P＜0.05);But the spleen index were not significantly different among the three groups (P＞0.05).③ At 21 days of age,the content of IgA and IgM in serum of groups Ⅲ were significantly higher than that of group Ⅰ (P＜0.05),and the content of IgG in serum of groups Ⅱ and Ⅲ were significantly higher than that of group Ⅰ (P＜0.05).④At 21 days of age,the content of IL-2,TNF-α and sIgA in intestinal mu cosa of groups Ⅱ and Ⅲ were significantly higher than that of group Ⅰ (P＜0.05),and the content of IL-6 in intestinal mucosa of group m were significantly higher than that of groups Ⅰ and Ⅱ (P＜0.05).⑤At 21 days of age,the villus height of jejunum in groups Ⅱ and lⅢ were significantly higher than that of group Ⅰ (P＜0.05),the villus height/crypt depth of jejunum in group Ⅱ was significantly higher than that of groups Ⅰ and Ⅲ (P＜0.05).However,the crypt depth was not significantly different among the three groups (P＞0.05).In conclusion,that Fagopyrum dibotrys (D.Don) Hara could not affect the growth performance of broilers,but it could improve the development of immune organs,increase the secretion of serum immunoglobulin,promote the immune function of intestinal mucosa and intestinal morphology of jejunum.关键词
