Abstract

Two experiments were conducted to determine the effects of processing whole-plant grain sorghum silage on stocker calf performance and in vivo digestibilities and to evaluate different lasalocid sodium levels on calf performance and rumen fermentation. Two silage treatments and 3 levels of lasalocid were compared in a growth trial. Dry matter intake and animal weight gains were greater for the whole-plant grain sorghum silage with whole grain than for grain sorghum silage with pre-ensiled rolled grain. No significant differences in rumen fermentation were found between silage treatments. Lasalocid sodium significantly depressed feed intake and improved feed efficiency at 33 ppm. Lasalocid at 49 ppm did not improve feed conversion over that of control steers but depressed (P < 0.05) daily gains. Lasalocid produced a shift in ruminal volatile fatty acid levels, reducing the acetate:propionate ratio. The apparent starch digestion of the post-ensiled rolled silage was greater (P < 0.05) than for the 2 other silage treatments. Apparent digestibility of dry matter, organic matter, crude protein and acid detergent fiber were similar for all treatments
