BRIONES MARTIN DEL CAMPO, Daniela Elizabeth et al. Preliminary genetic evaluation of Angus cattle in Mexico using genomic breeding values. Ecosistemas y recur. agropecuarios [online]. 2014, vol.1, n.2, pp.181-187. ISSN 2007-901X.

In order to genetically evaluate Angus cattle imported into Mexico as embryos, in comparison with an international reference population and cattle conceived locally, 143 Angus and Red Angus animals were genotyped with the IlluminaBovineSNP50BeadChip^® platform, and their genomic breeding values (MVP) were predicted. On average, they were superior to the mean of the reference population regarding traits like direct and maternal calving ease, milking ability, growth from weaning to yearling, carcass weight, muscle development, marbling and the feed lot economic index. The animals bred from imported germplasm were superior to those conceived locally regarding the traits of growth from weaning to yearling, muscle development, marbling, meat tenderness and the economic index. The Angus population that was evaluated proved to have genetic potential from which it is possible to select and use improved breeders.
