Some aspects to consider for improving reproduction of blu
Blue fox (Alopex lagopus) is the most important species for fur farming in Finland. At present selective breeding is focused to large and heavy animals. Ten years ago average weight of blue fox female varied from 7 to 10 kg. Today individuals over 20 kg can be found. Results of this study indicate t...

The first year's litter size/female is important when breeding animals are selected. In addition the blue fox breed should be taken into consideration when improvement of litter size is sought. The season when breeding animals are chosen is as well important. The average body size of blue fox female at the time of artificial insemination has an effect to the litter size.
