Means within a row, with no common superscript (a, b, c), differed significantly (P < 0.05). 1CON, the control group, cecal content and feed. 2MGH, the magnesium hydride group, cecal content, feed and 200 mg/l of MgH2. 3CMG, the coated-magnesium hydride group, cecal content, feed and 400 mg/l of coated MgH2. 4SEM, standard error of the mean.
