Body development and production capacity in dairy production are in relation. However, body development, i.e. exterior of cows does not define its functionality which is manifested in production of milk. Therefore, the capacity of cow to produce milk can only be determined more precisely by direct measuring of the production. Visual evaluation of body development and way to recognize the characteristics of dairy cows are initial parameters of milk traits, partially also longevity, as well as reproductive traits of the head of cattle, which is important from many aspects of the economical efficiency in dairy production. Exterior measures taken when cows were selected to be included in herd of bull dams, and which are also subject of this research, are following: height of withers, carcass length, breast depth, breast girth, body weight. For all investigated traits basic variation-statistical parameters were calculated. Average values of exterior measures obtained in this research were following: height of withers 136.29 cm, carcass length 165.50 cm, breast depth 72.97 cm, breast girth 200.07 cm, body weight 686.27 kg. Based on the presented data it can be concluded that traits of body development of Simmental bull dams are above the average values determined for controlled population, which further justifies our conclusion that bull dams are top heads of cattle of the main herd.
