北京油鸡多趾性状与产品品质相关性研究
Correlation Research of Beijing-You Chicken between Polydactyly Characteristic and Product Quality
摘要
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 gu-oup 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 1 60 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.关键词
