Abstract

This experiment was conducted to study the effects of dietary corn distillers dried grains with solubles (DDGS) and vitamin E (VE) on growth performance, carcass characteristics and meat quality of finishing pigs. The experiment was designed in a 3×2 factorial arrangement with three corn DDGS levels (0, 15% and 30%) and two VE levels (10 and 210 mg/kg). A total of forty-eight crossbred pigs (Duroc×Landrace×Large) with an average body weight of (60±2) kg were randomly allotted into 6 groups with 8 replicates per group and one pig in each pen. The results showed as follows: 1) different levels of dietary corn DDGS had no significant effects on average daily gain and feed/gain (P>0.05). With the increasing of dietary corn DDGS level, average daily feed intake was decreased significantly (P=0.006). Diets containing VE and the interaction between DDGS and VE level had no significant effects on growth performance (P>0.05). 2) There were no significant effects of dietary DDGS, VE, and DDGS×VE on carcass characteristics, including carcass weight, dressing percentage, carcass length, back fat thickness, leaf lard percentage and longissimus muscle area (P>0.05). Iodine value was increased significantly with the increasing of dietary DDGS level (P=0.001). 3) Diets containing different levels of corn DDGS had no significant effects on meat quality, such as pH, meat color, shear force, drip loss and marbling score (P>0.05), and high level (210 mg/kg) of VE decreased shear force and drip loss significantly (P<0.05). In conclusion, diets containing 15%~30% corn DDGS and 210 mg/kg VE have no significant negative influence on growth performance, carcass characteristics and meat quality of finishing pigs.
