Zinc oxidena-akpali proliferation nke eriri afọ epithelial cell, budata enwekwu ruru nke eriri afọ villus ịdị elu ka crypt omimi, mma n'elu ebe maka nutrient absorption, na n'out oge upregulates okwu nke uko njikọ protein (Occludin, ZO-1), ebelata eriri afọ mucosal permeability, na-egbochi mbuso agha nke pathogens. Ọ na-echebe ọrụ mgbochi mucosal intestinal, na-eme ka ikike antibacterial nke piglets dịkwuo mma, ma na-ebelata afọ ọsịsa.
