The effect of Leu on ruminal papillae morphology in beef cattle (n = 6). Representative rumen epithelial visual graph (A and C) and micrograph (B and D) of the beef cattle between CON and Leu. Visual images of the rumen tissues were taken with a camera. Images are obtained through a light micrograph of rumen tissue at a magnification of 10 × and 30 × objective lens.
