Summary:An abstract of a study by Genther-Schroeder and Hansen evaluating the effect of dietary grain inclusion and supplemental Zn on rumen epithelial structure and Zn transporter expression in ruminants is presented. In situ RNA expression of zip4 and zip5 were not affected by treatments (P ≥ 0.24) but there was an interaction in RNA expression of znt1, a Zn exporter (P = 0.04), where HG+CON was greater than other treatments. These data suggest dietary Zn has minimal effect on rumen histology, but may influence tight junction protein and znt1 expression in ruminants fed a high grain diet.
