Belgian Blue The Belgian Blue (French: Blanc-Bleu Belge , Dutch: Belgisch Witblauw ) is a breed of beef cattle from Belgium. It may also be known as the Race de la Moyenne et Haute Belgique . Alternative names for this breed include Belgian Blue-White; Belgian White and Blue Pied; Belgian White Blue; Blue; and Blue Belgian. The Belgian Blue's extremely lean, hyper-sculpted, ultra-muscular physique is termed "double-muscling". The double-muscling phenotype is a heritable condition resulting in an increased number of muscle fibers (hyperplasia), instead of the (normal) enlargement of "individual" muscle fibers (hypertrophy).
