Clustering of different types in a Charolais herd

Measurements were made in a nucleus herd of Charolais cows on pasture in early summer 1998. The average age and body weight of the cows were 6.8 years and 600 kg, repectively. Simultaneously to weighing, the following body parameters were measured with traditional measuring equipment (measuring rod and tape measure): height at withers, rump width II (distance between the femoral necks), slanting body length and chest girth.
