North American Piedmontese cattle are a breed of domestic beef cattle^[3]^: 128 originating from an imported herd of select Italian purebred Piedmontese cattle (Piemontese or razza bovina Piemontese). The foundation line of breeding stock was first imported from Italy into Canada in 1979, and into the United States in the early 1980s. Piedmontese cattle are distinguished by a unique,^[4] naturally occurring gene identified as the myostatin allele mutation, or inactive myostatin gene.^[3] Myostatin prohibits muscle growth whereas an inactive gene has the opposite effect. Purebred Piedmontese are homozygous, (2 copy), which means they have two identical alleles present for this unique gene. Research indicates the presence of the myostatin allele mutation produces morphological characteristics unique to the breed, such as double-muscling,^[A] beef tenderness, reduced fat content and high yield. According to the North American Piedmontese Association (NAPA), they are the first breed registry to base animal registration requirements on the presence of this specific gene which can be easily verified by DNA testing.
