Two-hundred and forty pigs (61.73 lb) were used in a 16-week study conducted to evaluate the feeding value of diets with varying concentrations of distillers dried grains with solubles (DDGS) for growing-finishing pigs. Pigs were assigned to one of four dietary treatments. Treatments consisted of a standard diet formulated on a standardized ileal digestible lysine (SID lys) basis in which a portion of dietary corn and soybean meal were replaced to include 0,5, 10 or 15% of DDGS in a 4-phase feeding regime. Treatment did not affect average daily gain (ADG), average daily feed intake (ADFI) or gain/feed (G:F) during the Grower 1, Grower 2, Finisher 1, and Finisher 2 feeding periods ( P > 0.10). Overall, no linear or quadratic effects in ADG and ADFI were recorded as dietary DDGS increased (P > 0.10). At day 21 and 42 backfat JBF) linearly decreased as dietary DDGS concentration increased (P = 0.008 and 0.018, respectively). A linear reduction in longissimus muscle area was recorded on day 42 JP = 0.025). Overall, growth performance was not affected by dietary DDGS inclusion increasing from 0 to 15%. The results of this study suggest that DDGS inclusion up to 15% in diets for growing-finishing pigs formulated on a SID lys basis does not affect optimum growth performance.
