Zusammenfassung:Pathological conditions and harmful drugs cause many gastrointestinal diseases in broiler chicken. The current study was conducted to investigate the effect of trace elements zinc (Zn) and selenium (Se) supplementation on histomorphology, immunological role, and functional activity of goblet cells (GCs) of the small intestine. The Alcian blue-periodic acid-Schiff (AB-PAS) was performed to assess the histomorphological changes in GCs, which revealed the regular dispersion with high electron density of GCs throughout the mucosal surface in the supplemented group. However, irregular dispersion with low electron density of GCs was present in the control group. The immunological functional role of GCs within the small intestine was examined by mucicarmine staining, immunohistochemistry, and immunofluorescence. The results showed a high mucin glycol protein secretion in the supplemented group, whereas limited mucin glycol protein secretion in the control group. Furthermore, the biological significance showed a high and low immunoreactivity of Muc2 and Muc13 in the supplemented and control groups, respectively. Immunofluorescence was used to confirm the immunosignaling of Muc2. Results revealed high immunosignaling of Muc2 at the apical part of the small intestine in the supplementation group, while low immunosignaling of Muc2 in the control group. Results suggest that trace element supplementation had significant effect on morphology and immunological role of GCs, which might be essential for immune function and health status of broiler chicken.
