Abstract: 【Objective】 This experiment was conducted to study the effects of chicory on growth performance,slaughter traits and meat quality of Mahuang broilers with different sex.【Method】 Five hundred and seventy-six Mahuang broilers at 42-day-old were randomly divided into 8 groups with 6 replicates in each group and 12 broilers per replicate (half male and half female).A 2×4 (sex×chicory) two-factor design was used,the chicory addition levels were 0,3%,6% and 9%,respectively.The experiment lasted for 42 days.At the end of the test,the growth performance indexes were statisticed,and one broiler in each replicate was slaughtered for the measurement of relevant indexes of slaughter and immune organs,and samples of breast and leg muscles were taken for meat quality analysis.【Result】 ①Compared with no chicory,adding 6% and 9% chicory could significantly increase the F/G of Mahuang broilers (P<0.05).The growth performance of male was significantly better than that of female (P<0.05).②The Bursa of Fabricius index of female was significantly higher than that of male (P<0.05).③The eviscerated rate of male was significantly higher than that of female (P<0.05),while the abdominal fat rate was significantly lower than that of female (P<0.05).④Compared with no chicory,adding 6% and 9% chicory could significantly improve the breast muscle b24h* of Mahuang broilers (P<0.05).The breast muscle L24h* of female was significantly higher than that of the male (P<0.05).⑤Sex and chicory level had significant interaction on the leg muscle shear force of Mahuang broilers (P<0.05),and adding 6% and 9% chicory could significantly decrease the leg muscle shear force of male compared with no chicory (P<0.05).Compared with the female,the a45min*,a24h* and b45min* of male leg muscle were significantly higher,while the L45min* and L24h* were significantly lower (P<0.05).Sex and chicory level had no significant interaction on growth performance,immune organ index,slaughter performance and breast muscle quality of Mahuang broilers (P>0.05).【Conclusion】 The growth performance,slaughter performance and muscle quality of male were better than those of female. Adding 6% and 9% chicory both could improve the meat quality of Mahuang broilers while have adverse effects on the F/G.According to the evaluation of various indicators,the optimum addition amount of chicory was 3%.
