Evaluation of corn germ and DDGS in diets fed to pigs
type: CreativeWork
description: Two experiments were conducted to determine effects of inclusion of distillers dried grains with solubles (DDGS) and corn germ to diets fed to growing-finishing pigs on pig growth performance, carcass composition, and pork fat quality. The first experiment was conducted to investigate if negative impacts of DDGS on carcass fat quality may be ameliorated by addition of corn germ, tallow, palm kernel oil, or glycerol to growing-finishing pig diets. The second experiment was conducted to determine the optimal inclusion rate of corn germ in growing-finishing pig diets that contained 0 or 30% DDGS. In Exp 1, a total of 36 gilts and 36 barrows (initial BW: 43.7 ± 2.0 kg) were randomly allotted to 1 of 6 dietary treatments and housed individually. A corn-soybean meal control diet and a corn-soybean meal diet containing 30% DDGS were formulated. Four additional DDGS based diets containing 15% corn germ, 3% tallow, 3% palm kernel oil, or 5% glycerol were also formulated. There were no differences among diets in ADG, ADFI, or G:F of the pigs. However, gilts had less (P < 0.05) ADG and ADFI and greater (P < 0.05) G:F than barrows. Most carcass characteristics were not affected by dietary treatments, but pigs fed diets containing the control diet had greater (P < 0.05) loin eye area compared with pigs fed the DDGS diet. It was observed that BW, HCW, and back fat thickness were greater (P < 0.05) for barrows than for gilts, but fat free lean percentage was greater (P < 0.05) for gilts than for barrows. There were no dietary effects on loin muscle quality, but barrows had greater (P < 0.05) marbling and 24-h loin pH than gilts. Belly quality was not influenced by dietary treatments, but gilts had lighter (P < 0.05) bellies than barrows. Belly flop distance was greater (P < 0.05) for pigs fed the control diet than for pigs fed the 5 DDGS-containing diets. However, there were no differences among pigs fed the DDGS diets. Belly flop distance was greater (P < 0.05) for barrows than f…
