condensed corn distillers solubles, finishing diets, steers
A trial was conducted as a randomized block design to assess the effects of condensed corn distillers solubles (CCDS) on performance and carcass merit of yearling steers (n = 21 6) fed 90% concentrate finishing diets. CCDS was included at 0 (MSBM), 5 (5CCDS1, 10 (IOCCDS), or 20% (20CCDS) of diet DM, replacing soybean meal, molasses, and corn. Average daily gain increased (PC .051 for steers fed CCDS but, along with a numerical trend (P= .14) of increasing DMI, resulted in no improvement in FIG (P>.20). Steers were harvested on day 108. Carcass weight and dressing percent for steers fed CCDS were greater than control steers (P< .01). Other carcass characteristics did not differ by treatment (P > .20). Ruminal fluid was collected by stomach tube from steers (n = 72) at -.5, + 1, +4, and + 7 hours from feeding. Values reported are means across sampling times. Ruminal fluid pH was higher for CCDS fed cattle than MSBM (P<.05). Butyrate increased with increasing CCDS level (PC .05). Differences in acetate, propionate, and NH3N were not significant (P> .20). The CCDS was an effective protein and energy source in 90% concentrate corn-based finishing diets. Based on performance, maximum inclusion rate is at least 20% of diet DM.
