Abstract

High moisture corn or sorghum silage on the performance, carcass and meat quality of steers receiving two protein levels were evaluated. Sixty-four steers were used with 293.5 kg as average weight. Experimental design was randomized blocks with 2x2 factorial arrangement: two protein levels (14% or 17%) and two grains (corn or sorghum), adding 4 treatments. Diets contained high moisture corn or sorghum silage, soybean, cracked corn, urea, oat hay (Avena sativa), mineral supplement and monensin. At the end of 162 days, the animals were slaughtered and then carcass and meat quality were evaluated. There was higher dressing for the animals receiving sorghum silage (p < 0.05). Animals receiving 17% protein and high moisture sorghum resulted in higher ether-extract in the meat (p=0.05). High moisture sorghum improved the carcass characteristics and meat quality.
