Abstract

To evaluate the main environmental factors in the productivity of Carmagnola Grey rabbits, an endangered breed indigenous to northern Italy, data collected over 8 years were analysed.   Production data on the pure closed nucleus herd of the University of Turin were used.  Effects of parity, season and age of weaning on the number of rabbits born alive and weaned, litter weight and individual average weight at weaning were studied.  The following average performance rates over the 8 years period were determined: 8.1 live born and 7.2 weaned kits per litter and a litter weight at weaning of 7287 g or 1024 g individual weaning weight.  Year and season both had a significant effect (P £ 0.001) on all the traits studied as well as weaning age (P £ 0.001).


Keywords
