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. 相似文献

In this study, the single nucleotide polymorphism(SNP) of MSTN gene and its correlation with the production performance was tested, and explored the molecular genetic marker of breeding in Baicheng fatty chicken. 96 Baicheng fatty chicken roosters were selected randomly and divided into 3 groups, there were 32 chicken in each group. The indexes of production performance were measured in 12, 18 and 24 weeks old and the SNP of MSTN gene was detected by PCR-RFLP method, and analyzed the relationship between gene polymorphism and production performance indexes.The results showed that 3 genotypes of AA,GA and GG were found in Baicheng fatty chicken, GA was the dominant genotype, and allele A was the dominant allele, the allele frequency was not in the Hardy-Weinberg equilibrium (P<0.05). At 12 weeks old,AA genotype was significantly higher than GA genotype in body weight, carcass weight,semi-eviscerated weight, eviscerated weight, breast muscle weight and leg muscle weight (P<0.05). At 18 weeks old,GA genotype was significantly higher than GG genotype in body weight, breast muscle weight and leg muscle weight (P<0.05). At 24 weeks old,AA genotype was extremely significantly higher in body weight, carcass weight and semi-eviscerated weight than GG genotype (P<0.01),and AA genotype was significantly higher in eviscerated weight and leg muscle weight than GG genotype (P<0.05). GA genotype was significantly higher in body weight, carcass weight,semi-eviscerated weight and leg muscle weight than GG genotype (P<0.05), there were no significant difference in the other indexes among different genotypes at different ages (P>0.05). MSTN gene polymorphism was closely related to the production performance indexes of Baicheng fatty chicken, it was speculated this gene could be used as one of the molecular genetic markers for the breeding of Baicheng fatty chicken. 相似文献
