Technical Abstract: Double muscling is a condition recognized in cattle for over a century, characterized by a visible muscular hypertrophy (mh) caused by muscle fiber hyperplasia. Some cattle breeds have been selected for this trait to the point where nearly every animal displays the double muscled syndrome, which includes effects on limb bone length, fat content, retail product yield, and fertility. Carcasses of double muscled animals are nearly ideal from a meat standpoint, delivering increased yield of the highest value cuts that are leaner than normal animals. This review discusses the positive and negative aspects of the double muscled syndrome, describes the process by which the gene responsible was discovered, and gives perspectives on how this information can be used in production systems to increase efficiency of lean meat production.
