Sažetak
The aim of this study was to assess the reproductive rates among different breeds, mostly used in commodity farm conditions. The studies were obtained at fertility level from 6.27 animals in the Californian breed to 8.49 animals in Popielno White. High rate of failures during rearing was observed in the Californian breed. Litter weight was dependent on the number of births and young rearing, lactation and care of female. Kitten weight at 35 day of age ranged from 603.21g (Alaskan) to 736.10g (Giant Chinchilla). The results indicate the usefulness of a Popielno White breed for the livestock production.
