The aim of the paper was to define the impact of the value of daily gains of body weight standardized on 180th day, i.e. low or high on meat content of pigs (young boars and gilts) of following breeds: Polish Landrace, Belgian Landrace, Hampshire, Duroc, Pietrain and Synthetic Line 990 (which was treated as a breed) performance tested in the year 2000 in the region activity of Regional Animal Breeding Station (OSHZ) in Bydgoszcz. In young boars of Polish Landrace, Belgian Landrace, Hampshire and Pietrain were not stated significant impact of value of daily gains of body weight on body meat content. Similar trends were in case of gilts mentioned breeds, except Polish Landrace animals. The pigs of 990 Line (both young boars and gilts) and gilts of Polish Landrace and Duroc breed characterized by lower growth rate had higher meat content compared with animals with high daily gains of body weight. Only in case of young boars of Duroc breed were stated significant impact of high growth rate on higher body meat content
