Tecnologías moleculares ómicas aplicadas al estudio del estrés por calor en ganado

The ability to tolerate extreme heat has been proposed as an important selection criterion to promote the breeding of thermo-tolerant animals, especially in climates characterized by environmental heat stress during most of the year. Novel genomic technologies are available to study genetic bases supporting the thermo-tolerance in cattle, among which are: Genome-wide association studies, validation of markers and candidate genes, RNA sequencing and transcriptome analysis. These technologies currently allow faster progress in the identification of thermotolerant cattle, which is highly relevant from the perspective of the current problems as global warming and food security. So, the objective of this review is to analyze the current status of the use of omics technologies in animal production studies under heat stress.
