鹌鹑肌肉肌苷酸含量和鹑肉保鲜时间的研究 总被引：3，自引：1，他引：2
用纸层析法测定鹌鹑肌肉提取液中的肌苷酸含量,实验结果表明:1.鹌鹑性别不同的肌苷酸含量(平均值):雌鹑为5.557μM/g(肉);雄鹑为5.274μM/g(肉),差异不显著(p>0.05)。2.两组不同日龄鹌鹑胸肌肌苷酸含量(平均值):35日龄为5.739μM/g,70日龄为4.941μM/g,差异极显著(p<0.01)。3.鹌鹑不同部位肌苷酸含量,胸肌明显高于腿肌,腿肌的肌苷酸含量平均值仅为胸肌的60.51％,差异极显著(p<0.01)。4.不同条件保存鹑肉时,随着时间的延长,肌肉中的肌苷酸均降解,降解速度,低温(0℃)较室温缓慢。5.测定肌肉中肌苷酸的含量可作为衡量鹌鹑肌肉鲜度的一项有用的指标。 相似文献

为了从分子水平上揭示朝鲜鹌鹑、中国黄羽鹌鹑、中国黑羽鹌鹑3个鹌鹑群体的遗传结构和亲缘关系,为鹌鹑的遗传资源研究提供科学依据,本研究采用PCR扩增、聚丙烯酰胺凝胶电泳、聚类分析等方法对3个鹌鹑群体进行了微卫星标记的多态性分析。结果表明,12个微卫星标记在3个鹌鹑群体中检测到的观测等位基因数在4~7个之间,中国黄羽鹌鹑、中国黑羽鹌鹑、朝鲜鹌鹑的平均多态信息含量分别为0.6853、0.6401和0.6565;平均期望杂合度分别为0.7333、0.6957和0.7111,以中国黄羽鹌鹑群体遗传多态样性最为丰富。聚类分析结果表明,中国黑羽鹌鹑和朝鲜鹌鹑的遗传距离最小为0.0628,因此中国黑羽鹌鹑和朝鲜鹌鹑先聚为一类,而后与中国黄羽鹌鹑聚合在一起。这也更进一步证明了中国黑羽鹌鹑和朝鲜鹌鹑有更近的亲缘关系,而中国黑羽鹌鹑,朝鲜鹌鹑与中国黄羽鹌鹑的亲缘关系要远一些。 相似文献

In order to reveal the genetic structure and genetic relationship of Korean quail, Chinese Yellow quail, Chinese Black quail, the 3 quail populations from the molecular level, to provide for the study of genetic resources of quail.This study used PCR amplification, polyacrylamide gel electrophoresis, cluster analysis and other methods of 3 quail populations were polymorphic analysis of microsatellite markers.The results showed that 12 microsatellite markers in 3 quails was detected in the observed number of alleles was between 4 and 7, the average polymorphism information content of Chinese Yellow quail, Chinese Black quail, Korean quail were 0.6853, 0.6401 and 0.6565, respectively;The average heterozygosity were 0.7333, 0.6957 and 0.7111, respectively, which Chinese Yellow quail population genetic diversity was the most abundant polymorphism.The cluster analysis showed that the Chinese Black quail and Korean quail smallest genetic distance was 0.0628, so the Chinese Black quail and Korean quail were clustered into one category, and then was Chinese Yellow quail together.This was further evidence of Chinese Black quail and Korean quail had a closer genetic relationship, and the genetic relationship of Chinese Black quail and Korean quail was more distant with Chinese Yellow quail. 相似文献

The purpose of this study was to accelerate the application of molecular markers in genetic breeding and other aspects of Black quail to develop EST-SSR markers for Black quail.100 Black quail were randomly chosen and blood samples were collected to develop EST-SSR new markers and determined the genetic polymorphism using bioinformatics.The results showed that there were 6 EST-SSR markers in the Black quail, the number of observed alleles in EST-SSR was 2 to 6.The average PIC of 6 EST-SSR markers in the Back quail was 0.4962 and the average He was 0.5759.Markers P1 and P2 were highly polymorphic markers among 6 EST-SSR and the rest EST-SSR markers were moderately polymorphic markers.These developed markers could be used for genetic diversity analysis of Black quail and the EST-SSR markers had some relationship with the carbohydrate metabolism, synthesis of melanin in Black quail, but the mechanism needed the further analysis. 相似文献

The poultry feather color inheritance has been a hot research topic, because the feather color is a kind of important quality character.In this study, we used polyacrylamide gel electrophoresis to detect the polymorphisms of four quail populations of different feather color (China Yellow quail, Black quail, Korean quail, Beijing White quail) of agouti-related protein gene (Agrp) exon Ⅰ, so as to investigate the relationship of Agrp exon I with quail plumage color, and to provide reference for the breeding and production of quail.The results showed that two alleles were detected in the Agrp exon Ⅰ of China Yellow quail, Black quail, Korean quail, Beijing White quail populations,and expressed by A and B, respectively. Frequency of allele A in Beijing White quail was up to 0.9500. The frequency of B allele in Korean quail was the highest, reaching 0.3392, in Beijing White quail genes in the lowest frequency is only 0.0500. The genotype frequency of AA genotype in Beijing White quail was the highest (0.9500), the lowest in Korean quail and Black quail (0.4286). BB genotype was not observed in Beijing White quail. We speculated that it may have a certain relationship between Agrp exon Ⅰ B allele and feather color of quail. 相似文献

This study aimed to evaluate the differences between the growth patterns of large- and normal-sized Japanese quail strains and their F1 progeny, by fitting their growth parameter values to five nonlinear regression growth models (Weibull, Logistic, Gompertz, Richards, and Brody). The Richards model presented the best fit for both sexes of the large-sized quail strain, whereas the Gompertz model presented the best fit for both sexes of the normal-sized quail strain, based on goodness-of-fit criteria (higher adjusted R2 and lower Akaike and Bayesian information criteria). Both sexes of F1 birds derived from the cross between normal-sized females and large-sized males were best fitted by the Richards model. In contrast, growth parameters of the F1 birds derived from the cross between large-sized females and normal-sized males were best fitted to the Gompertz model. The data could be fitted nearly as well to the Weibull and Logistic models as to the Richards and Gompertz models. The Brody model presented the poorest fit for the growth parameter values. The results indicated that the Richards and Gompertz models could best describe the growth characteristics of both large- and normal-sized quails. Moreover, the observed growth pattern of the F1 birds was likely inherited from the male parental strain. To the best of our knowledge, this is the first study comparing the growth curves of the reciprocal F1 generations with their parental strains in quails. 相似文献

MC1R基因与朝鲜鹌鹑羽色关系的研究 总被引：1，自引：0，他引：1
黑素皮质素受体1(MC1R)又称促黑素细胞激素受体(MSH-R),由毛色扩展位点编码而成,对动物体色的形成起重要作用,本研究分析了MC1R基因突变与朝鲜鹌鹑羽色之间的关系。通过混合样品DNA测序方法寻找MC1R基因的突变位点,采用PCR-SSCP的方法对突变位点在4种羽色鹌鹑(栗羽、黄羽、白羽、黑羽)群体中的分布情况进行了研究,以揭示MC1R基因与鹌鹑羽色性状之间的关系。结果表明,在鹌鹑MC1R基因上存在一个A/G突变位点,导致编码蛋白发生Ile58Val突变,通过PCR-SSCP分析发现,该突变位点在4种羽色鹌鹑群体间没有显著差异(P>0.05)。本研究没有发现与日本鹌鹑报道相同的Glu92Lys突变位点,表明朝鲜鹌鹑的黑羽突变与报道的日本鹌鹑黑羽突变的机制不同,而且朝鲜鹌鹑的黑羽突变可能还与其它基因突变有关。 相似文献
