2008 Univ of NE Swine Report- The Effect of Corn Distillers Dried Grain
Two-hundred forty growing-finishing pigs were used to evaluate the feeding value of distillers dried grains with solubles (DDGS). Treatments consisted of 0, 5, 10 and 15% dietary DDGS inclusion. Treatments did not affect average daily gain (ADG), aver-age daily feed intake (ADFI) or gain: feed (G: F) during the grower 1 period(P > 0.05). During the grower 2 period, ADG and ADFI linearly decreased as DDGS increased (P < 0.05). No differences among treatments were detected throughout the feeding phase finisher 1 for ADG, ADFI, and G:F (P > 0.05). During the finisher 2 feeding phase, there was a linear reduction in ADG and ADFI in response to dietary DDGS inclusion (P = 0.01). Overall, linear reductions in ADG, ADFI, and G:F were recorded as dietary DDGS increased(P < 0.05). Backfat and loingissimus muscle area decreased as dietary DDGS concentration increased (P < 0.05). Overall, growth performance was reduced as dietary DDGS inclusion increased from 0 to 15%. The reduction in performance may have been partially explained or exacerbated by the elevated fiber concentration detected in the source of DDGS used in this study.
