On the basis of the faecal egg counts (epg), the effect of intestinal nematode infection on the productive traits of gilts fattened at Pig Testing Stations (PTS) during 1994-1995 was evaluated. Presumably due to a full-constituent pelleted feed mixture given ad libitum, only in some cases the infection significantly lowered the daily gain, feed convertion or meat content in carcass of gilts, and in some - the phenomenon of resilience was observed. The highest influence on the productivity had station factors.
