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...
Conditioned taste aversion in the grey fox ( Pseudalopex griseus), in Southern Argentine Patagonia
Contributor(s):: Nielsen, S., Travaini, A., Vassallo, A. I., Procopio, D., Zapata, S. C.
Attempts to control cougar ( Puma concolor) and culpeo fox ( Pseudalopex culpaeus) populations in Patagonia through poisoning, negatively affects grey foxes ( Pseudalopex griseus) and many other non-target species. It is therefore advisable to develop selective predator control methods. Among a...

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,...
Bones as enrichment for farmed blue foxes ( Vulpes lagopus ): interaction with the bones and preference for a cage with the bones
| Contributor(s):: Koistinen, T., Turunen, A., Kiviniemi, V., Ahola, L., Mononen, J.
Animal welfare regulations (e.g. Recommendations of European Convention) state that farmed foxes need to be provided with an activity object, though the material or shape of the object is not specified. We aimed to evaluate the properties of bones as an activity object for farmed blue foxes...
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...
Feeding enrichment in an opportunistic carnivore: the red fox
| Contributor(s):: Kistler, C., Hegglin, D., Wurbel, H., Konig, B.
In captive carnivores, species-specific behaviour is often restricted by inadequate feeding regimens. Feeding live prey is not feasible in most places and food delivery is often highly predictable in space and time which is considerably different from the situation in the wild. As a result,...
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...
Position of operant cost affects blue foxes' time budget between sand floor and mesh floor
| Contributor(s):: Koistinen, T., Orjala, H., Mononen, J., Korhonen, H. T.
The aim of the study was to assess whether positioning of the operant cost would affect blue foxes' (Vulpes lagopus) behaviour and time budget between a mesh floor and sand floor. We built fourteen test apparatuses, six consisting of two fox cages with a mesh floor in both cages and eight with a...
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...
Effects of environmental stressors on deep body temperature and activity levels in silver fox vixens ( Vulpes vulpes )
| Contributor(s):: Bakken, M., Moe, R. O., Smith, A. J., Selle, G. M. E.
The present study was performed to investigate the effects of 14 different environmental stimuli on stress-induced hyperthermia (SIH) and levels of locomotor activity in 6 (3 infanticidal (killed their offspring during the previous year), 3 non-infanticidal) 2.5-year-old silver fox vixens. The...
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...
Preference for various nest box designs in farmed silver foxes ( Vulpes vulpes ) and blue foxes ( Alopex lagopus )
| Contributor(s):: Jeppesen, L. L., Pedersen, V., Heller, K. E.
Nest box choice experiments were carried out outside the breeding season on adult silver (n=50) and blue fox (n=50) vixens with no previous permanent nest box experience. Nest boxes were varied in height of placement, number of rooms, presence of entrance room or platform and light conditions....
Social preferences in farmed silver fox females ( Vulpes vulpes ): does it change with age?
| Contributor(s):: Akre, A. K., Bakken, M., Hovland, A. L.
Determining foxes' social preference, and how this influences their social behaviour towards different conspecifics at different ages may give us a better understanding of how to prevent foxes from exposure of possible social stressors when housed in groups. Here, we investigated the effect of...

| Contributor(s):: Waiblinger, S., Boivin, X., Pedersen, V., Tosi, M. V., Janczak, A. M., Visser, E. K., Jones, R. B.
The present paper focuses on six main issues. First, we briefly explain why an increased understanding of the human-animal relationship (HAR) is an essential component of any strategy intended to improve the welfare of farmed animals and their stockpersons. Second, we list the main internal and...
A comparison of the use of resting platforms and nest boxes in growing farmed silver foxes ( Vulpes vulpes )
| Contributor(s):: Mononen, J., Korhonen, H., Harri, M., Kasanen, S.
The use of the interior and roof of a nest box and the use of various types of resting platform were studied in 50 juvenile silver foxes of both sexes housed singly in traditional fox cages (length, 115 cm; width, 105 cm; height, 70 cm). The experiment was carried out from early July to the end...
