The objective of this research was to determine the effect of group size on pig performance. A field study was carried out during 15 months. The building had 52 pens in total, which housed grower pigs to 35-38 kg body weight. During the first 8 months the average number of animals was 726. During the time of most significant decrease of performance in months 9 and 10 the average number went up to 751 animals. A reduction in total feed intake was observed during months 9, 10 and 11 and the average consumption of compound feed per animal and day dropped to 1.68, 1.32 and 1.09 kg. Consequently the weight gain decreased to 615, 535 and 505 g, respectively. The example showed the negative influence of overstocking of grower pigs on the essential performance indicators, such as weight gain, compound feed consumption per feeding day and feed conversion. The number of animals in pens should be decided on the basis of stocking density which influence positively performance. The size of the lying area for this particular age group and this particular building should be between 0.48 and 0.51 sq m per animal.

Celem badań było określenie wpływu efektu obsady zwierząt w budynku na wyniki użytkowości trzody chlewnej. Badania terenowe trwały 15 miesięcy. Obserwowany budynek posiadał ogółem 52 kojce do utrzymywania warchlaków do masy ciała 35-38 kg. W pierwszych 8 miesiącach średnia obsada budynku wynosiła 726 szt. W okresie istotnego pogorszenia się wyników użytkowości warchlaków, w 9 i 10 miesiącu, średnia obsada zwiększyła się do 751 zwierząt. Zaobserwowano zmniejszone zużycie paszy w miesiącach 9, 10 i 11 i korespondowało to ze zmniejszonym średnim dobowym pobraniem paszy przez warchlaka, które obniżyło się odpowiednio do 1,68; 1,32 i 1,09 kg. Odpowiednio obniżeniu uległy średnie przyrosty dobowe do 615, 535 i 505 g. Na przykładzie tym wykazano negatywny wpływ przegęszczenia obsady warchlaków na podstawowe wskaźniki użytkowości tucznej, takie jak przyrost masy ciała, pobranie paszy na dobę i konwersję paszy na przyrost masy ciała. O zagęszczeniu zwierząt w kojcach powinno się decydować w oparciu o obsadę, która wpływa korzystnie na wyniki użytkowości. Dla grupy wiekowej warchlaków w badanym budynku określono optymalną wielkość powierzchni legowiskowej dla 1 sztuki na 0,48 -0,51 m2.
