Functional genomics in the field of animal science: state-of-the-art and perspectives

The last twenty years have been characterized by some remarkable technological advances in the field of genomics which were essential to unveil the genome of varies species. Furthermore, these genomic advances contributed to pinpoint particularities in genome sequences which might be associated with phenotypic variations, therefore, it became possible to study functions associated with specific sequences in a more holistic context within biological systems. More importantly, the blossoming in genomics contributed to a better understanding on the mechanisms that control the interactions between genotype and environmental factors which are responsible for phenotypic variability. Genomic advances also promoted innovative and multi-dimensional scientific perspectives in research fields of biology, such as in animal science. Having in mind the remarkable impacts of genomics on the understanding of biological phenomena, it becomes clear that an assessment of the potential applications of functional genomics in the field ruminant nutrition should be performed. For this reason, this paper reviews several important genomic tools, and discusses the feasibility of using these tools towards an enhancement of animal production.
