不同饲养方式对拜城油鸡生长、屠宰性能及肉品质的影响
Effects of Different Feeding Patterns on Growth and Slaughter Performances and Meat Quality of Baicheng- you Chickens
摘要
Abstract
[Objective] The effect of different feeding patterns on growth and slaughter performances and meat quality of Baicheng - you chickens were studied. [ Method ] Three hundreds 1 - day - old Baicheng -you chickens with similar body weight were randomly distributed to 3 groups with 4 pens per group and 25 chicks per pen. Three groups were fed with three feeding patterns; free range, floor - rearing and net -rearing. All chickens were fed the same diet for 12 weeks. [Result] Final body weight and feed intake decreased in the free range group compared with floor - rearing group and net - rearing group ( P < 0.05 ) , the semi - eviscerated weights (P < 0. 05) and the percentage of abdominal fat (P < 0. 05 or P < 0. 01) was significantly decreased in the free range group compared with the other two groups. 24h and 48h drip loss of free range group was significantly decreased compared with the floor - rearing group and the net - rearing group (P < 0. 05 or P < 0. 01) in the breast and leg muscle. Shear force in muscle of free range group wassignificantly higher than that in other two groups (P <0.05) , respectively, breast meat color (OD value) of free range group was significantly higher than other groups ( P < 0.05). Ash contents of leg muscle of the free range were significantly improved compared with the floor - rearing and net - rearing (P < 0. 01 ), respectively. The contents of the breast and leg muscle intramuscular fat and inosinic acid in the free range group were higher than those in the other two groups (P <0.05), respectively. The diameters of muscle fiber of leg and breast muscle in the net - rearing group were significantly reduced compared with the other two groups ( P < 0.05), muscle fiber density is less than floor - rearing group and free - range group ( P < 0.05), respectively. [ Conclusion]Three feeding manners have their own advantages and appropriate feeding manners choices should be based on the conditions of breeders and different market requirements of the different chicken products.关键词
