Absztrakt

Authors jointly analyzed dataset measuring the reproductive performance of Hungarian Large White (LW, n=37806), Hungarian Landrace (LR, n=13620) and their cross (F1, n=40652). Number of records was 283528 collected for 92082 dams born between 1999−2004. Using the Weibull model (survival analysis) lifetime performances of the different genotypes were evaluated. The herd effects were significant for both lifetime performance traits (age at culling, total number of piglets born alive). The effect of age was only significant for total number of piglets born alive although the differences were small. Inbreeding on the other hand unfavourably affected lifetime performance for both traits.
