Sažetak
Research on growth capacity of different genotypes of gilts was carried out at the station for performance test of gilts. Two groups of gilts, German Landrace and Swedish Landrace, 15 each were included in the experiment, while 3rd group contained 14 crossed gilts (Swedish Landrace x Large White). Using asymmetric S-function, differences were observed in growth characteristics between genotypes of gilts. Growth curves for gilts were depicted by following models:
German Landrace f(t)
Swedish Landrace f(t)
Crosses (SL x LW) f(t)
Pigs with higher average daily gain reach maximal growth rates (inflexion point) in earlier age, and stage of progressive growth lasts shorter time than in animals with lower average daily gain. Inflexion point was reach in 166.59 days in German Landrace gilts, 171.14 days in Swedish Landrace and 168.53 days in crossed gilts (SL x LW).
