Abstract

Sixty Santa Ines ram lambs (16.4 kg BW and 67 days old) were used to evaluate the replacement of sugar cane bagasse (SB) by soybean hulls (SH) as NDF source on performance and carcass characteristics. The trial was conduced on a factorial arrangement 2 x 2 + 1 (two NDF sources: SB and SH, two NDF level: 14% and 18% and a control treatment containing 100% of concentrate), in a complete randomized block design, with five treatments and six replications. Animals on SH diets had higher ave-rage daily gain (P=0.07) than animals on SB. Diets con-taining fiber sources (SB or SH) had higher dry matter intake (PV 0.75) (P=0.09) compared to 100% concentrate diet. There was no difference (P>0.10) on feed conver-sion, carcass chilling losses, ribeye area and fat thickness. An interaction (P≤0.07) among NDF source and level was observed for the hot and cold carcasses yields. Soybean hulls improved performance when compared to sugar cane bagasse and can be used as the only fiber source in high concentrate diets for feedlot lambs.
