Cattlemen's Day, 1986; Kansas Agricultural Experiment Station contribution; no. 86-320-S; Report of progress (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service); 494; Beef; Sodium bicarbonate; Sodium bentonite; Digestion; Ruminal fermentation; Sorghum silage


One percent sodium bicarbonate increased intake of a 50% silage-50% grain ration, but had no effect on intake of an 84% sorghum silage ration. Adding concentrate (rolled sorghum grain) lowered rumen pH slightly and decreased acid detergent fiber and starch digestion. The bicarbonate had no effect on digestibility, but 2% bentonite lowered digestibility of neutral and acid detergent fiber. Neither compound affected ruminal fermentation characteristics.
