Abstract: The genetic trends for certain body weight traits in cows and calves on the basis of data base comprising information for over 100 years, gathered for the analysed farm was evaluated. The trend was increasing for the following traits: body weight at birth, body weight at 12 and 15 months and cow body weight after 1st, 2nd and 3rd calving. For dairy cattle both birth body weight and cow body weight, together with exterior traits should be considered as additional selection criteria for improvement.
