ResumenTwo trials were conducted to evaluate the influence of virginiamycin (26 mg/kg) and monensin (34 mg/kg) supplementation of a steam-flaked corn-based finishing diet containing 15\% distiller dried grains plus solubles (DDGS) on growth performance and digestive function. In Trial 1, 135 steers (257 +/- 21 kg) were used to evaluate treatment effects on 145-d growth performance. There were no treatment effects (P > 0.20) on dry matter intake (DMI). Antibiotic supplementation tended to increase average daily gain (ADG; 7\%, P = 0.07); increased gain efficiency (11\%, P < 0.01) and estimated dietary net energy (NE; 10\%, P < 0.01). Carcass marbling score was greater (12\%, P = 0.04) for virginiamycin vs. monensin. In Trial 2, three Holstein steers (300 +/- 7 kg) were used in a 3 x 3 Latin square to evaluate treatment effects on digestion. Both monensin and virginiamycin depressed ruminal digestion of organic matter (OM; 6\%, P < 0.01) and feed nitrogen (N, 15\%, P = 0.03) and microbial protein synthesis (15\%, P = 0.03). There were no treatment effects of total tract OM and N digestion. Antibiotic supplementation increased (2.3\%, P = 0.02) ruminal pH, associated with decreased (7\%, P = 0.04) ruminal volatile fatty acids (VFA) concentrations. It is concluded that monensin and virginiamycin supplementation of growing-finishing diets for feedlot cattle may enhance daily weight gain, gain efficiency and dietary energetics. These effects are associated with a shift towards great intestinal OM digestion and decreased ruminal degradation of feed N and microbial protein synthesis.es_ES
