Abstract

Supplementation with corn silage (CS) or grain sorghum silage (SS) on average daily gain (ADG), rate of subcutaneous fat deposition (RFD) and ruminal fermentation characteristics were evaluated in 42 Angus×Hereford steers (187±26 kg) grazing high quality pastures. Steers were assigned to one of three treatments in a randomized design being; TP, fresh pasture (700 g/kg grass and 300 g/kg legumes) fed ad libitum; TCS or TSS, with restricted pasture plus CS or SS, both finely chopped and rolled at dough grain stage, representing 400 g/kg of the total diet on DM basis, respectively. Two paddocks per treatment and 7 steers per paddock were used. Average daily gain was not affected by treatments (mean = 0.939 kg/day), but RFD was lower (P<0.03) for TSS versus TP steers.
