Effect of Using Ensilaged Corn Wet Distillers’ Grains Plus Solubles (WDGS) as a Partial Replacement for Concentrated Feed for Wet Lot Fed Fatteners during Fattening on Growth Performance, Carcass Characteristics and Pork Quality

2023

The purpose of this study was to determine the nutritional suitability of WDGS in pigs’ feeding and production. Pigs were liquid fed and divided into 3 groups. Pigs in the control group were fed diets based on cereal grains, while the experimental groups were also given 10% or 15% WDGS, which partially replaced their cereal grains. During this study, the average daily gains (ADG), feed intake, chemical composition of meat, fatty acid profile of meat, and quality parameters of the carcass and meat were examined. The highest statistical weight gains were detected for the group WDGS 10% during the first stage of the fattening period. No statistical differences were detected for the final body weight, carcass traits, chemical composition of the meat or the composition of fatty acids such as SFAs, PUFAs, and MUFAs, with the exception of eicosenoic acid (C20:1n9). Pigs fed on 10% WDGS exhibited lower peroxidation of lipids (TBARS) than the control group or WDGS 15%. Similarly, water holding capacity (WHC) was the lowest for the group WDGS 10%. Of the meat coloration, redness (a*), yellowness (b*), and chroma (C*) were affected by the WDGS’ inclusion, where the highest values were observed for the group WDGS 10%. In conclusion, WDGS can be utilized in the liquid feeding of pigs for up to 15% of their DM.
