Abstract

Feeding studies with steers were conducted to evaluate two samples (A and B) of sugarcane condensed molasses solubles (CMS) as a feedstuff for ruminants. The CMS contained 53.3 and 52.6% dry matter (DM) and, on a DM basis, 23.8 and 32.6% ash and 10.2 and 8.7% crude protein for samples A and B, respectively. In Exp. 1 (CMS A) and 2 (CMS B), 40 yearling steers were fed 0, 5, 10 or 15% of CMS (DM basis) substituted for corn and(or) soybean meal irk a concentrate diet for 56 d. Steers from Exp. 2 were fed an additional 28 d except that steers consuming 15% CMS were changed to the basal diet due to poor performance. Reduced daily gains and less efficient feed conversion (P<.05) occurred when steers were fed CMS in excess of 5% of diet DM. Carcass characteristics were unaffected by treatment. Ruminal propionic acid concentration was decreased (P<.05) for diets containing 10 or 15% CMS. Butyric acid was increased (P<.05) for all levels of CMS. Liver Zn decreased (P<.05) and kidney Mn increased (P<.05) as dietary CMS increased. Muscle Fe was also elevated (P<.05) by CMS. The CMS had less value than corn as an ingredient in diets for finishing cattle. The studies suggest that sugarcane CMS should not be used in diets intended to promote maximum gains.
