ResumenThe effect of two forage neutral detergent fiber (NDF) levels (6 vs. 9\%) and two forage sources (sorghum stover vs. alfalfa hay) on growth performance was evaluated in 20 feedlot lambs (17.45 +/- 2.75kg) for a 60-d feeding-period. Final longissimus area and subcutaneous fat were measured by ultrasound. There were no treatment interactions. Lambs receiving sorghum stover had greater gain efficiency (p=.04), estimated dietary net energy (NE; p=.04), longissimus area (p=.02) and tended to greater average daily gain (ADG; p=.06) than lambs fed alfalfa hay. Lambs receiving 6\% forage NDF had greater ADG (p=.03), gain efficiency (p=.03) and tendency toward for dietary NE (p=.06) than those fed 9\% forage NDF. Treatments did not influence subcutaneous fat. In conclusion, at equivalent forage NDF level, sorghum stover may be superior to alfalfa hay for feedlot lambs which may depress growth performance at 9\% forage NDF in isocaloric diets including a 50:50 blend of whole and ground sorghum grain.es_ES
