Ltd，Jiangyan, Jiangsu 225538 Abstract: The feeding test was conducted to evaluate the effect of Cactus PE on slaughter performance and meat quality of Guangxi partridge chicken .1600 Guangxi partridge chickens were randomly assigned to 2 groups , each group had 2 repeats. Control group was provided with basic diet, while test group was fed with basic diets added Cactus PE for 120 days. The results showed that test group was significant difference in comparing body weight, slaughter weight, percentage of half-eviscerated yield, percentage of eviscerated yield, dressed percentage ,percentage of leg muscle, percentage of breast muscle with control group(P 0.05). Index of the meat quality in this test was improved a little for the test group(P＞0.05). The conclusion of the study was Cactus PE can improve slaughter performance and meat quality of Guangxi partridge chicken.
