复方中草药对三黄鸡生长性能、抗氧化能力、 屠宰性能及经济效益的影响.

This experiment was to study the effects of compound Chinese herbal additives on growth performance, antioxidant capacity, slaughter performance and economic benefit of Sanhuang chickens. A total of 288 1-day-old Sanhuang chickens were randomly divided into 4 groups with 6 replicates per group and 12 chickens per replicate. Group A was the control group, and groups B, C and D were fed 0.5%, 1.0% and 2.0% compound Chinese herbs, respectively, for 56 days. The results showed as follows: from day 1 to day 56, compared with group A, FBW, ADG and ADFI in groups B and C were significantly increased (P<0.05); there were no significant differences in T-SOD, T-AOC and GSH-Px activities in experimental groups (P>0.05), but MDA content in group C was significantly decreased (P<0.05). There were no significant differences in slaughter rate, half evisceration rate, full evisceration rate, chest muscle rate and abdominal fat rate in experimental groups (P>0.05), while leg muscle rate in group C was significantly increased (P<0.05). The total gross profit and average gross profit of the experimental group were improved. In conclusion, the compound Chinese herbs used in this experiment can improve the growth performance and slaughter performance of Sanhuang chickens, enhance the antioxidant capacity, and make Sanhuang chickens obtain higher economic benefits, the optimal additive dosage is 1.0%.
