Abstract: For the analysed farm researchers studied database covering over 100 years and researchers estimated genetic trends for chosen functional and conformation traits. Generally, for the traits like, e.g., longevity, length of production period or the age of the first calving the trend has been slowly decreasing. For conformation traits concerning animal size the trend has been increasing. Both functional and conformation traits should be treated as additional selection criteria in the process of trait improvement.
