Analysis of association between polymorphism of TFB2M gene and meat quality,growth and slaughter traits in Guizhou white goat,a well-known Chinese indigenous goat breed

The present study aims to determine the useful snps in tfb2m gene and explore their effects on the meat quality in guizhou white goat. in this study,the technologies of dna pool,direct sequencing and pcrsscp were -adopted to screen the snps of tfb2m gene in 29 experimental guizhou white goats. we analyzed the association between the polymorphism of tfb2m gene and the growth traits,meat quality traits and slaughter traits in experimental goats. it is shown from the results that a17110c locus was detected in exon 8,and three genotypes (aa,ac and cc) were discovered by sscp. the association analysis showed that there was no significant difference in growth traits (p>0.05),meanwhile snps (a17110c) made a certain influence on bone weight in guizhou white goat,and the individuals of genotype aa were superior than genotype ac in bone weight (p<0.05). according to the results in this study,it is suggested that tfb2m gene might be regarded as a candidate gene affecting bone weight in goats. copyright 2015 zoological society of pakistan.
