Growth of the Ardennes draught horse is not well known as compared to other draught breed horses. Biometry is the science which allows a mathematical approach of measured parameters. The technic provides tools for assessments of growth, aids to diagnosis of skeletal pathologies and assessments of sports aptitudes. According to Martin-Rosset (1990), live weight correlates to the thoracic perimeter. The aim of this study is to use other morphology traits to assess growth rates in Ardennes males foals.
