Abstract:
This experiment was conducted to study the effects of replacing feed protein by Herme-tia illucens larvae meal on immune function,intestinal morphology and microflora of Sichuan white geese.A total of 64 healthy 1-day-old Sichuan white geese were randomly allocated into 4 groups with 4 replicates in each group and 4 geese in each replicate,namely the control group,the 2％HILM,4％HILM and 8％HILM groups fed diets contained 0％,2％,4％and 8％of HILM,re-spectively.The experimental period was 40 days.The results showed that compared with the con-trol group,8％HILM increased the levels of serum IgG1,IgG2a and complement C3,and the difference was statistically significant(P＜0.01).4％HILM significantly increased the expression level of CD4(P＜0.05),and 8％HILM significantly increased the expression level of IL-10(P＜0.05).The ratio of villus length to crypt depth(VH/CD)in the jejunum and ileum in 4％HILM group was significantly increased(P＜0.05).The SIgA level of jejunum was significantly increased in all HILM replacement groups(P＞0.05).The abundance of Bacteroides in 4％HILM group were extremely significantly increased(P＜0.01),and the abundance of Bilophila and Bilophila wadsworthia were significantly decreased in all HILM replacement groups(P＜0.05).In conclu-sion,HILM can enhance the immune function of Sichuan white geese,improve the intestinal mor-phology of jejunum and ileum,enhance the local mucosal immunity of jejunum,increase the abun-dance of beneficial bacteria in cecum and decrease the abundance of harmful bacteria in cecum,and protect intestinal health.
