There is interest to increase growth rates in beef cattle through various means such as hormone implants (Bagley et al., 1989) or by selective breeding based on EPDs (Kress et al., 1977). Improved growth rates are typically associated with higher economic returns to beef producers. High marker density genomic maps have greatly facilitated the detection of quantitative trait loci (QTLs). Chromosomal regions identified as harbouring QTLs can be screened for candidate genes with physiological roles influencing the trait with the goal of isolating the actual QTL for the trait under investigation.
