MARTINEZ, Rodrigo Alfredo. Contribution of animal genetic improvement to livestock systems resilience. Cuban J. Agric. Sci. [online]. 2019, vol.53, n.2, pp.103-108.  Epub Apr 01, 2019. ISSN 0864-0408.

The objective of this study was to show a review of the studies carried out in Creole breeds in aspects of conservation, characterization and selection using genomic information, for the traditional characteristics, but it also includes variables related to disease tolerance and adaptation such as the heat tolerance index and the adaptation coefficient, which allow having populations with higher productivity but conserving their adaptive capacities to tropical conditions, therefore they will be more resilient to climate variability. Additionally, the study exposes the selection strategies for newly introduced breeds such as the Cebu Brahman breed and Simmental breed, carried out with the participation of farmer associations and focused on the multiplication of genetically superior animals, using cutting-edge reproductive tools, responding effectively to the needs of adaptation or resilience imposed by the change in environmental conditions that occur in tropical regions.

Keywords : genetics; resilience; creole breeds; Cebu Brahman; Simmental.
