Quantitative analysis of birth, weaning, and yearling weights and calving difficulty in piedmontese crossbreds segregating an inactive myostatin allele

The Piedmontese breed has a high frequency of double-muscling. Animals tested in this breed are homozygous for a guanine to adenine transition in exon 3 (C313Y) of the myostatin (MSTN) gene. This transition seems to be responsible for the double-muscling phenotype. The objective of this study was to...
