Effects of group size and early handling on some behavioural and physiological welfare parameters in farmed blue foxes

Abstract

The present study included two procedures, both aimed at improving animal welfare: early handling and changing the social conditions of the animals. Production and welfare related parameters as well as behaviour were assessed in blue fox (Alopex lagopus) cubs who were either handled or not before weaning, and housed after weaning either in pairs or in six-animal groups. The effect of the larger group size was observed in the larger number of bite scars in the female cubs housed in six-animal groups. Furthermore, the group size seemed to affect the performance of foxes most clearly in the late autumn when intra-litter aggression was observed during the feeding test. On the other hand, early handling had only short-term positive effects on the performance of the foxes but later transpired to have a negative impact on the stress profile of these animals.
