Effects of different feeding methods on meat quality traits,fatty acids,amino acids and volatile flavor compounds of Wenchang chicken
摘要
Abstract
The experiment was to study the effects of different feeding methods on meat quality traits,fatty acids,amino acids and volatile flavor compounds of Wenchang chicken.A total of thirty 21-day-old Wenchang chickens were selected randomly divided into two groups with 15 replicates per group and one chicken per replicate.The caged group was fed a corn-soybean meal diet,while the free-range group was fed under rubber forest with morning and evening supplemental diet.The test period was 90 days.The results showed that breast muscle weight in free-range group was extremely higher than that in caged group(P<0.01).The color yellowness of in free-range group was extremely lower than that in caged group(P<0.01),the chest muscle shear force was extremely higher than that in caged group(P<0.01),the chest muscle fiber diameter was extremely higher than that in caged group(P<0.01),and the muscle fiber density was extremely lower than that in caged group(P<0.01).The crude protein content in breast muscle of in caged group was extremely higher than that in free-range group(P<0.01).The contents of lysine,asparagine and glutamine in breast muscle of in free-range group were significantly higher than those in caged group(P<0.05),and the content of histidine was extremely higher than that in caged group(P<0.01).The alanine content of in caged group was extremely higher than that in free-range group(P<0.01).The contents of arachidonic acid and heptadecanoic acid in chest muscle of free-range rearing group were significantly higher than those of cage rearing group(P<0.05 or P<0.01),and the content of palmitoleic acid in breast muscle in caged group was significantly higher than that in free range group(P<0.05).The composition of volatile flavoring substances in breast muscle in free-range group was better than that in caged group.The study indicates that the breast muscle color is better in free-range group,and the content and composition of functional amino acids,fatty acids and flavor substances in breast muscle are better than those in cage-raised Wenchang chicken,indicating that the quality of free-range Wenchang chicken is better.关键词
