Abstract

This experiment was conducted to study the effects of dietary levels of corn distillers dried grains with solubles (DDGS) on growth performance and meat quality in geese. One hundred and sixty Yangzhou geese aged 3 weeks were randomly divided into 4 groups, each of which was replicated 4 times with 10 geese per replicate. The control group was fed a corn-soybean meal based diet, and experimental groups Ⅰ,Ⅱ and Ⅲ were fed the basal diets containing 10%, 20% and 30% corn DDGS, respectively. Body weight and feed intake were measured weekly. At the end of the experiment, 32 geese were slaughtered and the samples of the breast and leg muscle were taken and measured for the meat quality. An adaptation period lasted for 1 week and was followed by an experiment period for 6 weeks (4 to 10 weeks of age). Results showed that no differences were found in average daily feed intake and feed/gain by adding corn DDGS to the diets (P>0.05). There was no significant difference in average daily gain among all groups during the experiment period (P>0.05) even though body weight of geese in experimental group Ⅱ was significantly higher than that of geese in the control group at 8 and 9 weeks of age (P<0.05). Also no significant difference occurred in pH, meat color, shear force, and water loss rate of breast muscle between experimental groups and control group (P>0.05). However, leg muscle TBARS content of geese in experimental groups Ⅰ and Ⅱ was significantly higher than that of geese in the control group on the first day of the determination period (P<0.05), and much higher TBARS content was found on the fourth and fifth day between each experimental group and control group (P<0.05). From the measured results on each day during the 5-day determination period, there was a trend in TBARS content to increase firstly and then decrease with the dietary levels of corn DDGS increased. In conclusion, there are no effects on growth performance and conventional meat quality when diets containing 0 to 30% corn DDGS, but feeding diets containing corn DDGS to geese results in an acceleration of lipid oxidation in muscle, which will cause the rancidity.
