To meet the demands of increased global meat consumption, animal production systems will have to become
more efficient, or at least maintain the current efficiency utilizing feed ingredients that are not also used for
human consumption. Use of growth promoters is a potential option for increasing production animal feed efficiency
and increased muscle growth. The objective of this manuscript is to describe the mechanisms by which
the growth promoters, beta-adrenergic agonists and growth hormone,mediate their effects,with specific consideration
of the aspects which have implications for meat quality.
