Abstract：The experiment aimed to investigate the effects of fermented corn gluten meal on growth and development,immune function,and intestinal flora of chicks.A total of 360 Hyline brown chicks were randomly divided into six groups with six replicates with 10 chicks per replicate:Control group(CON group),cyclophosphamide injection group(CY group),corn gluten meal group(CGM group),fermented corn gluten meal group(FCGM group),corn gluten meal+cyclophosphamide group(CGM+CY group),and fermented corn gluten meal+cyclophosphamide group(FCGM+CY group).The CY group received intraperitoneal injections of cyclophosphamide at 32 mg/(kg·bird)for two weeks,while the other groups were fed diets with with corn gluten meal or fermented corn gluten meal to replace 10％basic diet.The test period was 21 days.The results showed that compared with the control group,fermented corn gluten meal group increased the average daily gain,average daily feed intake,tibia length,and liver weight of chicks(P＜0.05),increased the weights of the thymus,spleen,and bursa of Fabricius(P＜0.05).The expression levels of polymeric immunoglobulin receptor(PIGR)in the spleen and bursa of Fabricius were elevated(P＜0.05),while the expression levels of tumor necrosis factor receptor-associated factor 6(TRAF6)and TRAF-interacting forkhead-associated protein(TIFA)were reduced(P＜0.05).The abundance of Lactobacillus,Coprococcus,Weissella,and Dorea increased,whereas the abundance of Enterococcus and Corynebacterium decreased.The study indicates that replacing 10％of the basic diet with fermented corn gluten meal can enhance growth performance,improve immune function,and positively modulate the intestinal flora of chicks.
