Dynamic changes of antibody-forming cells in local immune tissues of chicks administrated with probiotics

1-day-old chicks were fed with commodity probiotics or home-made probiotics for 3 days, the experimental chicks were taken to collect cecal tonsils, glands of Harder and Peyer' s patch to defect the dynamic changes of IgA-forming cells、IgG-forming cells、IgM-forming cells by application of immunohistochemistry staining after administration probiotics 1、4、7、10、18 days. The results were as follows; the IgA-forming cells、IgG-forming cells、IgM-forming cells in local immune tissues of chicks after administration probiotics 4 ～ 7 days were enhanced compared with those of without probiotics. Results showed that orally fed probiotics enhanced the IgA-forming cells、IgG-forming cells and IgM-forming cells in local immune tissues of chicks and the effect was pronounced in the commodity probiotics treatment. The difference between commodity probiotics group and home-made probiotics group was closely related with becterium and technology of proceeds.
