ABSTRACT
The aim of this study was to investigate the effects of dietary distillers dried grains with solubles (DDGS) on growth performance, meat quality and fatty acid composition of pork belly. A total of 50 gilts and 50 barrows (initial BW 26±6.3 kg) were randomly allotted to 2 diets including a corn-based control diet and control plus 9% DDGS. After 105 d administration of experimental diets, growth performance, pork quality traits, and fatty acid composition in loin were analyzed. No significant difference in growth performance and quality traits of pork loin between control and DDGS was observed. Fatty acid composition in pork belly, however, was significantly affected by DDGS treatment. Levels of palmitoleic acid (C16:1) and oleic acid (C18:1) which are positively associated with meat flavor, were greater (p<0.05) in DDGS compared to control group. Supplementation of DDGS increased (p<0.05) the level of conjugated linoleic acid, which has been reported to reduce body fat accumulation, when compared with control group. Taken together, these data indicate that DDGS can be utilized as a feed additive and has beneficial effects on unsaturated fatty acid formation in pork without deleterious effect on growth performance.
