目的是比较和分析增长之间的关系,嘌呤含量,尿酸,纯种和杂交泰国土鸡的超氧化物歧化酶(SOD)。总共300只泰国土鸡被分为3组。第1组是纯种泰国土鸡(100%TN),第2组是50%泰国本地鸡(50%TN),第3组是25%泰国本地鸡(25%TN)。数据包括体重(BW),平均日增益(ADG),和胸围(BrC)。在6、8和10周龄时,每组10只鸡随机安乐死收集胸肉,肝脏,和血液样本来分析由总嘌呤组成的嘌呤含量,腺嘌呤,鸟嘌呤,黄嘌呤,和次黄嘌呤,和尿酸,在胸肉和肝脏和血液中的SOD。一般的线性模型,采用Pearson相关和主成分分析对变量间的显著性差异和相关性进行分析。结果表明,25%TN组各年龄段生长性状最高,而100%TN组最低(p<0.05)。与嘌呤值的分析结果一致,随着年龄的增长,胸肉和肝脏中的嘌呤含量和尿酸以及血液中的SOD含量降低(p<0.05)。嘌呤含量(总嘌呤,腺嘌呤,鸟嘌呤,黄嘌呤,和次黄嘌呤)和生长性状(BW,ADG,和BrC)范围从中度阴性到中度阳性(-0.542至0.253)(p<0.05)。尿酸与生长性状(0.348~0.760)、SOD与生长性状(0.132~0.516)呈低-中度正相关,差异显著(p<0.05)。主成分图,其中强调了三个主要成分(PC1、PC2和PC3),解释了胸肉和肝脏中总信息的86.44%和86.53%,用于选择动物以实现生长性状变异的最佳平衡,嘌呤含量,尿酸,和SOD。尽管纯种泰国土鸡表现出最低的生长性状,嘌呤含量,尿酸,与杂交泰国本地鸡相比,SOD也最低。因此,在泰国土鸡中发展遗传学以生产健康食品是可能的。
The objective was to compare and analyze the relationship between growth, purine content, uric acid, and superoxide dismutase (SOD) in purebred and crossbred Thai native chickens. A total of 300 Thai native chickens were divided into 3 groups. Group 1 was purebred Thai native chickens (100%TN), Group 2 was 50% Thai native chickens (50%TN), and Group 3 was 25% Thai native chickens (25%TN). Data included the body weight (BW), average daily gain (ADG), and breast circumference (BrC). At 6, 8, and 10 weeks of age, 10 chickens from each group were randomly euthanized to collect breast meat, liver, and blood samples to analyze the purine content consisting of total purine, adenine, guanine, xanthine, and hypoxanthine, and uric acid, in breast meat and liver and SOD in blood. A general linear model, Pearson correlation and principal component analysis were used to analyze the significant differences and relationship between variables. The results showed the 25%TN group had the highest growth traits at every age, while the 100%TN group had the lowest (p < 0.05). Consistent with the analysis results of purine values, purine content and uric acid in breast meat and liver and SOD in blood decreased with age (p < 0.05). The correlations between purine content (total purine, adenine, guanine, xanthine, and hypoxanthine) and growth traits (BW, ADG, and BrC) ranged from moderate negative to moderate positive (-0.542 to 0.253)(p < 0.05). The correlations between uric acid and growth traits (0.348-0.760) and SOD and growth traits (0.132-0.516) were low to moderate positive with significant differences (p < 0.05). The principal component plot, which highlighted three principal components (PC 1, PC 2, and PC 3), explained 86.44 and 86.53% of the total information in breast meat and liver for selecting animals for optimal balance of the variation in the growth traits, purine content, uric acid, and SOD. Although purebred Thai native chickens showed the lowest growth traits, purine content, uric acid, and SOD were also lowest compared to crossbred Thai native chickens. Therefore, the development of genetics in Thai native chickens to produce healthy food could be possible.
