Myf5 and MyoG gene SNPs associated with Bian chicken growth trait

Y. Wei, Zhang, G. X., Zhang, T., Wang, J. Y., Fan, Q. C., Tang, Y., Ding, F. X., Zhang, L., Wei, Y., Zhang, G. X., Zhang, T., Wang, J. Y., Fan, Q. C., Tang, Y., Ding, F. X., and Zhang, L., Myf5 and MyoG gene SNPs associated with Bian chicken growth trait, vol. 15, p. -, 2016.

The growth trait is important in poultry production. We analyzed the association between single nucleotide polymorphisms (SNPs) in the Myf5 and MyoG gene and Bian chicken growth traits. SNPs in candidate genes of the Bian chickens were detected by the polymerase chain reaction-single strand conformation polymorphism method. Two mutation loci and six genotypes were identified in each candidate gene.

Identification of SNPs in growth-related genes in Colombian creole cattle

R. Martínez, Rocha, J. F., Bejarano, D., Gómez, Y., Abuabara, Y., Gallego, J., Martínez, R., Rocha, J. F., Bejarano, D., Gómez, Y., Abuabara, Y., and Gallego, J., Identification of SNPs in growth-related genes in Colombian creole cattle, vol. 15, p. -, 2016.

Colombian creole cattle have important adaptation traits related to heat tolerance and reproductive and productive efficiency. Romosinuano (ROMO) and Blanco Orejinegro (BON) are the most common breeds used by Colombian cattle breeders. Growth traits are of prime importance in these animals, which are mainly raised for beef production. Genes encoding growth hormone, growth hormone receptor, homeobox protein, insulin growth factor binding protein 3, leptin, and myostatin have been associated with physiological growth pathways in cattle and other species.

Identification of SNPs located on BTA 6 and BTA 20 significantly associated with bovine respiratory disease in crossbred cattle

S. L. Miller, Mizell, S., Walker, R., Page, T., Garcia, M. D., Miller, S. L., Mizell, S., Walker, R., Page, T., and Garcia, M. D., Identification of SNPs located on BTA 6 and BTA 20 significantly associated with bovine respiratory disease in crossbred cattle, vol. 15, p. -, 2016.

The objective of the present study was to evaluate single nucleotide polymorphisms (SNPs) located in two quantitative trait locus (QTL) regions (BTA 6 and BTA 20) that are associated with bovine respiratory disease (BRD). A population of 323 crossbred steers sired by five purebred sire breeds during 2010-2013 (Angus, Braford, Braunvieh, Charolais, and Simmental) were evaluated for BRD susceptibility during the finishing process at a commercial feedlot.

APOA5 polymorphisms associated with lipid metabolism in Brazilian children and adolescents

E. De França, Silva, D. S. B. S., Silva, T. F. C., Dornelles, C. L., Alves, J. G., Alho, C. S., De França, E., Silva, D. S. B. S., Silva, T. F. C., Dornelles, C. L., Alves, J. G., Alho, C. S., De França, E., Silva, D. S. B. S., Silva, T. F. C., Dornelles, C. L., Alves, J. G., and Alho, C. S., APOA5 polymorphisms associated with lipid metabolism in Brazilian children and adolescents, vol. 15, p. -, 2016.

Single nucleotide polymorphisms in the APOA5 gene have been studied for their association with metabolic syndrome. Thus, elucidating the effect of the mechanism involved in APOA5 gene polymorphisms on lipid metabolism is of great importance. In this study we aimed to determine the allelic and genotypic frequencies of -1131T>C, Ser19Trp, and intergenic APOA4/A5 and to evaluate the association between these variants with plasma lipid levels in children and adolescents from Brazil.

Molecular markers located on the DGAT1, CAST, and LEPR genes and their associations with milk production and fertility traits in Holstein cattle

R. Hill, Canal, A., Bondioli, K., Morell, R., Garcia, M. D., Hill, R., Canal, A., Bondioli, K., Morell, R., Garcia, M. D., Hill, R., Canal, A., Bondioli, K., Morell, R., and Garcia, M. D., Molecular markers located on the DGAT1, CAST, and LEPR genes and their associations with milk production and fertility traits in Holstein cattle, vol. 15, p. -, 2016.

The objective of the present study was to investigate single nucleotide polymorphisms (SNPs) located in three candidate genes previously reported to have effects on fertility and milk production traits in a population of 123 Holstein cows. The milk production traits evaluated included lifetime averages of milk yield, protein concentration, and fat concentration. Fertility traits evaluated included lifetime averages of services per conception and days-open.
