Abstract: In order to study the effects of feeding methods and feeding time on the quality of hybrid high-quality meat chicken,two cross combinations of DZ and QX of Chongqing local chicken were selected to analyze the differences of slaughter performance and meat quality traits under different feeding methods(cage and free range)and different feeding time(120,150 days old),and the composition of free amino acids and flavor nucleotides was determined TAV and EUC were used to evaluate the taste characters.The results showed that feeding methods,feeding days and cross combinations could affect the growth performance,slaughter performance and meat quality of high-quality broilers.The results showed that the meat performance of DZ and QX hybrids in cage was higher than that in free range(P<0.01),and that at 150 days was higher than that at 120 days(P<0.05);the meat color in free range was better than that in cage,and that in 150 days was better than that in 120 days;there was no difference in muscle shear force between different feeding methods and feeding ages(P>0.05);the content of total delicious amino acids in free range was higher than that in cage(P<0.05),and that in 150 days old was higher than that in 20 days old(P<0.01).The content of IMP in free range was higher than that in cage culture(P<0.05),the contents of IMP,GMP and AMP in 150 day old were higher than 120 day old(P<0.01,P<0.05). The results showed that 150 days old was better than 120 days old,free range rearing was better than cage rearing,DZ combination was better than QX combination,and the highest EUC was 135.52 mg/g at 150 days of age.Feeding time was more significant for improving meat quality and taste of DZ and QX cross combinations,which provided scientific basis for the development and utilization of local chicken resources and the establishment of related chicken quality evaluation methods.
