AB - Abstract A total of 1,890 growing-finishing pigs (PIC; 359 × 1050; initially 27.1 kg) were used in a 124-d growth trial to compare the effects of pigs fed diets with high-protein dried distillers grains (HPDDG) or conventional dried distillers grains with solubles (DDGS) on growth performance and carcass characteristics. Conventional DDGS contained 29.0% CP, 0.48% standardized ileal digestible (SID) Lys and 9.2% oil, whereas HPDDG contained 39.3% CP, 0.68% SID Lys and 11.1% oil. All diets were formulated on an equal SID Lys-basis with diets containing HPDDG having less soybean meal than diets with conventional DDGS. There were 27 pigs per pen and 14 pens per treatment. Treatments were arranged in a 2×2 + 1 factorial with main effects of DDG source (conventional DDGS or HPDDG) and level (15 or 30%). A corn-soybean meal-based diet served as the control and allowed linear and quadratic level effects to be determined within each DDG source. Pens were assigned to treatments in a randomized complete block design with initial weight as the blocking factor. Data were analyzed using lme4 package in R (version 3.5.2) with pen as experimental unit. Overall, there were no differences observed in ADG between pigs fed either DDG source. Pigs fed HPDDG had decreased (P< 0.001) ADFI and increased (P< 0.001) G:F compared with those fed conventional DDGS. Increasing either conventional DDGS or HPDDG decreased carcass yield and HCW (linear, P< 0.02); however, there were no differences between pigs fed HPDDG or conventional DDGS. Iodine value (IV) was greater (P< 0.001) in pigs fed HPDDG than conventional DDGS, and IV increased (linear, P< 0.02) with increasing DDG. These data suggest that pigs fed HPDDG had greater G:F and IV compared with pigs fed conventional DDGS, probably due to the difference in oil content.
