Increasing the productivity is one of the main objectives in livestock breeding programs. Traits such as milk production, milk fat content, and number of offspring are economically important for both North American farmers and farmers in developing countries . In tropical areas, increasing feed efficiency, milk production, heat tolerance, disease resistance and meat quality are critical to move from a small farmer from subsistence to profitability. Traditional breeding methods have led to better production but this is slow and not easily attainable for quantitative traits controlled by multiple genes with low heritability. Selecting critical alleles at these loci using new genomic approaches will help farmers with their breeding programs . Genetic information linked to information obtained from automated feed and milk equipment, together with temperature monitoring systems, will further help farmers make important decisions on improving feeding strategies and increase profitability.
