Effects of Increasing Soybean Meal in Diets Based on Corn and Dried Distillers Grains with Solubles on Growth Performance and Carcass Characteristics of Late Finishing Pigs

A total of 1,827 pigs (L337 × 1050, PIC; initially 215.8 ± 2.5 lb) were used to evaluate the effects increasing soybean meal (SBM) in corn-DDGS-based diets on growth performance late finishing pigs. Pens blocked by BW and randomly assigned 1 5 dietary treatments with 14 replications per treatment. Experimental corn-based 25% DDGS. Soybean levels increased from 0 16% 4% increments replacing added feed grade AA. weighed ADG, ADFI, F/G. Data analyzed GLIMMIX procedure SAS pen was considered as experimental unit. The statistical model fixed treatment, linear quadratic contrasts, random group block. Overall, final marginally (quadratic; P < 0.10) SBM increased, greatest improvement observed when contained 8% SBM. However, there no differences among overall or Furthermore, influence carcass characteristics. These results suggest that concentrations contain DDGS did not
