| 摘 要： | 本研究旨在探讨不同趾型北京油鸡产品品质的差异，通过对其生产性能、蛋品质和肉品特征的比较分析，获知北京油鸡多趾特征与其产品品质之间的相关性，为北京油鸡特色养殖及产品品质开发利用提供参考。试验选取肉蛋兼用型北京油鸡，分为3组（双四趾、单五趾和双五趾），每组4个重复，每个重复60只鸡，共720只，分别对其生产性能（体重、产蛋率和蛋重）、蛋品质（哈氏单位）及肌肉品质（保水性、剪切力、TPA、核苷酸代谢产物）进行测定。结果显示，双五趾北京油鸡在120和240日龄的体重均略高于双四趾和单五趾北京油鸡，但差异不显著（P>0.05）；双五趾北京油鸡160日龄的蛋重显著高于其他趾型北京油鸡（P<0.05）。双五趾油鸡腿肌保水性显著好于其他趾型（P<0.05），腿肌硬度、胶着性和咀嚼性显著低于双四趾和单五趾油鸡（P<0.05），而内聚性和弹性则显著高于其他趾型（P<0.05），双五趾油鸡腿肌的剪切力显著高于其他趾型腿肌（P<0.05），不同趾型间北京油鸡风味物质无显著差异（P>0.05）。双五趾北京油鸡在前期体重与蛋重方面表现优于双四趾北京油鸡，但差异不显著（P>0.05）。此外，不同趾型北京油鸡肌肉品质各有优势。总体来看，北京油鸡腿肌品质与趾型相关性大于胸肌。 |

| Abstract: | The purpose of this study was to explore differences of the Beijing-You chicken product quality between different dactyly.Through the production performance,egg quality and meat characteristics comparative analysis research,we could get the correlation between the Beijing-You chicken polydactyly characteristic and its product quality.So this research could provide the reference to characteristic breeding and the development of the product quality of Beijing-You chicken.In this test,we selected Beijing-You chicken (for meat and eggs),and divided into 3 groups (four-toed (4F),single five toes (SF) and double five toes (DF)) with 4 replicates per guoup and 60 hens per replicate, 720 hens totally.Then,the production performance (weight,laying rate and egg weight),egg quality (haugh unit) and muscle quality (pH,waterholding capacity,shear force,TPA,andnucleotide metabolites) were determined,respectively.The results showed that the weight of DF Beijing-You chicken in 120 days and 240 days of age were slightly higher than that of 4F and SF Beijing-You chicken,but no significant difference (P>0.05);The egg weight of DF Beijing-You chicken in 160 days of age was significantly higher than other Beijing-You chicken (P<0.05).As for DF Beijing-You chicken,the waterholding capacity in leg muscles was better than the other types (P<0.05),hardness,conglutination and chewing of leg muscle were significantly lower than other types (P<0.05),while the cohesiveness and elasticity were significantly higher than other toe types (P<0.05).The shear force in leg muscles of DF and SF Beijing-You chickens were significantly higher than other types (P<0.05),the flavor substance shared no difference between different dactyly Beijing-You chicken (P>0.05).The performance of body weight and egg weigh of DF Beijing-You chicken were superior than 4F and SF Beijing-You chicken in the early stage,but had no significant difference.In addition,the muscle quality of different dactyly Beijing-You chicken had their own advantages,overall,the correlation between leg muscle quality and different dactyly was greater than the brisket. |
