Blue foxes' ( Vulpes lagopus) motivation to gain access and interact with various resources
Contributor(s):: Koistinen, T., Korhonen, H. T., Hamalainen, E., Mononen, J.
We analysed the willingness of blue foxes ( Vulpes lagopus) to work for and utilise five resources: a platform, wooden block, sand floor, nest box and empty space. Ten juvenile blue fox males were housed singly in apparatus consisting of three cages connected with one-way doors through the walls...
Workaholic ferrets: does a two-chamber consumer demand study give insight in the preferences of laboratory ferrets ( Mustela putorius furo)?
Contributor(s):: Reijgwart, M. L., Vinke, C. M., Hendriksen, C. F. M., Meer, M. van der, Schoemaker, N. J., Zeeland, Y. R. A. van
Although provision of environmental enrichment is an effective tool to refine laboratory animal experiments, it is currently unknown which enrichments ferrets prefer. This study aimed to assess the suitability of a closed economy, two-chamber consumer demand set-up to determine ferrets'...
Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink
Contributor(s):: Malmkvist, J., Palme, R.
Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...
The reliability of welfare assessment according to the WelFur-protocol in the nursing period of mink (Neovison vison) is challenged by increasing welfare problems prior to weaning
Contributor(s):: Henriksen, B. I. F., Moller, S. H.
The objective of this study was to test the hypothesis that the body condition of the mink dam, the frequency of dirty nests, frequency of injuries and diarrhoea change significantly with the day of assessment, post-partum, within the data collection period from parturition to weaning,...
Potential welfare impacts of kill-trapping European moles ( Talpa europaea) using scissor traps and duffus traps: a post mortem examination study
Contributor(s):: Baker, S. E., Shaw, R. F., Atkinson, R. P. D., West, P., Macdonald, D. W.
Moles are widely trapped as pests on farms and amenity land in Britain. Spring traps for killing mammals generally require welfare approval in the UK, but mole traps are exempt. Previous research demonstrated wide variation in the mechanical performance of mole traps. In this context, we aimed to...
Non-human animal abuse and wildlife trade: harm in the fur and falcon trades
Contributor(s):: Wyatt, T.
Until recently, the field of criminology has largely ignored the suffering and abuse of non-human animals in the variety of forms in which it occurs. In order to address one aspect of this suffering, this article explores the non-human animal abuse inherent in the trade of wildlife. To...

Behavioural and physiological effects of post-weaning handling and access to shelters in farmed blue foxes ( Alopex lagopus )
Contributor(s):: Pedersen, V., Moeller, N. H., Jeppesen, L. L.
Ninety-four female blue fox Alopex lagopus cubs were distributed into two groups with either handling or no handling. Handling was performed once a day for 2.5 min between 7 and 10 weeks of age, while the control group received no extra human contact. As handling completed at 10 weeks of age,...
Choices of farm foxes for raised wire mesh cage and ground pen
Contributor(s):: Korhonen, H., Niemela, P.
Eight adult male silver foxes (Vulpes vulpes) and 10 adult and 10 juvenile blue foxes (Alopex lagopus) were housed in a combined cage-pen housing. A raised wire mesh cage (110 x 107 x 60 cm) was connected via tunnel with a ground level pen with solid floor (200 x 400 x 150 cm). Animal behaviour...
Long-term effects of tryptophan on behavioural response and growing-furring performance in silver fox ( Vulpes vulpes )
Contributor(s):: Rouvinen, K., Archbold, S., Laffin, S., Harri, M.
The effects of dietary tryptophan (TRP) supplementation on behavioural response, body weight, feed intake and winter fur development were assessed in silver fox pups from 28 July until 5 December 1997. Ten males and 10 females received a commercial fox ration (control) and 10 males and 10 females...
Relative value of a nest box, sand floor and extra space during the breeding season in adult blue fox males
Contributor(s):: Koistinen, T., Jauhiainen, L., Korhonen, H. T.
We measured how much adult blue fox males value access to a nest box and sand floor enrichments while a platform and activity object are available simultaneously. Ten blue fox males were solitary housed in test apparatuses with permanent access to a platform and wooden block (activity object)...
Selection for more confident foxes in Finland and Norway: heritability and selection response for confident behaviour in blue foxes ( Alopex lagopus )
Contributor(s):: Kenttamies, H., Nordrum, N. V., Brenoe, U. T., Smeds, K., Johannessen, K. R., Bakken, M.
As a part of a Nordic project, 'Selection for more confident foxes', selection experiments with blue foxes lasting 4 years (1995-98) were arranged in Finland and Norway. In Finland, the study was carried out on a private farm with closed selection and production lines. In Norway, the experiment...
The effects of surgical and chemical castration on intermale aggression, sexual behaviour and play behaviour in the male ferret ( Mustela putorius furo )
Contributor(s):: Vinke, C. M., Deijk, R. van, Houx, B. B., Schoemaker, N. J.
The ferret (Mustela putorius furo) has become an increasingly popular pet animal, yet little is known about their behaviour and welfare. Inter- and intra-specific aggression and the intense musky scent are the two main reasons why male ferrets are normally surgically castrated. However, it is...
Effects of early weaning and housing conditions on the development of stereotypies in farmed mink
Contributor(s):: Jeppesen, L. L., Heller, K. E., Dalsgaard, T.
141 female mink pups were weaned at 6, 8 or 10 weeks of age and subjected to two different housing conditions. They were either kept together with a single male sibling in traditional mink cages (30 x 45 x 90 cm) or housed socially with all litter-mates in an alternative system consisting of...
Group housing of adult silver fox ( Vulpes vulpes ) vixens during autumn and its consequences for body weight, injuries and later reproduction: a field study
Contributor(s):: Hovland, A. L., Bakken, M.
Usually, farmed silver foxes are housed singly throughout adulthood. Due to the flexible social nature of wild foxes social grouping may act as an alternative housing procedure for adult vixens. However, sociality may involve increased levels of aggression during competition for e.g. dominance...
Increasing costs of access to resources cause re-scheduling of behaviour in American mink ( Mustela vison ): implications for the assessment of behavioural priorities
Contributor(s):: Cooper, J. J., Mason, G. J.
Consumer demand studies of animal preference commonly involve the imposition of costs on access to resource compartments rather than direct costs on resource consumption. The aim of this study was to analyse how such increasing access costs alter the scheduling of behaviour, in order to...
