Differential count of the goblet cells (GCs) in the intestine of Nile tilapia fed on SeNPs0.75 mg/Kg, or SeNPs1.5 mg/Kg feed or basal diets for 8 weeks. A. AB & PAS double staining showing color differentiation of four types of the GCs, including mucin-free (negative stain), acid mucin-producing (blue, A), neutral mucin-producing (pink, N), and mixed mucin-producing cells (purple, M). B Bars demonstrate the statistical analysis of the intestinal goblet cells count of non-supplemented Nile tilapia or fed with SeNPs0.75 mg/Kg, or SeNPs1.5 mg/Kg supplemented diets. Data were expressed as Mean ± SEM. Values with a different letter superscript are significantly different between groups
