Wpływ zarażenia nicieniami jelitowymi na produkcyjność loszek uzyskiwaną w stacjach kontroli SKURTCH

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.
