Abstract: The present study was conducted to determine the effect of different housing systems on meat flavor compound of Beijing-You chicken.A total of three hundred 49-day-old healthy Beijing-You chicken were randomly assigned to two groups (housing systems of cage-rearing and floor-rearing with outdoor access).Each group had five replicates with thirty broilers per replicate.The experiment ended at 91 days of age.The results showed that compared with the cage-rearing group,meat fatty acid of the chicken in floor-rearing with outdoor access including C16:0,C16:1,C18:1n9c,C18:2n9c,C22:0,SFA and UFA contents were significantly improved (P<0.05),C15:1,C18:0,C18:2n9t and C20:4n6 contents had a tendency to increase,but no significant difference was found between this two groups (P>0.05).The IMP content of the chicken in floor-rearing with outdoor access was significantly higher than that in the cage-rearing group (P<0.05).Volatile flavor compounds in both housing systems present different percentage rate.The percentage of ketones and alcohols of the chicken in floor-rearing with outdoor access was higher,relative to the cage-rearing group,the aldehydes content was reduced.This was the reason of odor rendering differences.The results suggested that different housing system affected the composition and relative contents of flavor compounds,the chicken in floor-rearing with outdoor access could improve meat quality and flavor of Beijing-You chicken.
