Effect of cage dimensions on welfare and production of farmed blue fox
Korhonen, Hannu T.; Orjala, Hanna
Annals of animal science : 3 (2010)Comprehensive scientific interest has been to improve the housing environment of farmed foxes by both enriching the traditional cage and increasing its size (Mononen, 1996; Hovland and Bakken, 2000; Ahola, 2002; Koistinen ... -
Effect of enlarged cage on production in foxes
Hannu. T. Korhonen; Orjala, Hanna
NJF Report : 8 (Nordic Association of Agricultural Scientists, 2009)The aim was to find out the effect of higher and wider cage on production in farmed blue fox. Three different cage setups formed the three experimental groups: 1) control group in standard cage; 2) high cage, walls ... -
How blue foxes value an earth floor
Orjala, Hanna; Koistinen, Tarja; Mononen, Jaakko; Korhonen, Hannu T. (2007)Farmed blue foxes are willing to work for access to an earth floor. However, when the foxes have free access to earth and wire mesh floors they prefer the wire mesh floor, in particular while resting. Consequently, it ... -

Preliminary results of using behavioural latencies to assess the use of sand floor in blue foxes
Orjala, Hanna; Koistinen, Tarja; Korhonen, Hannu T.
Scientifur : 4 (2010)The aim of this study was to study why blue foxes change floor material between a mesh floor and sand floor. We measured latencies of various behaviours after the fox entered the sand and mesh floor. Our Blue foxes could ... -
Use of behavioural latencies to assess the value of sand floor in blue fox (Vulpes Lagopus)
Orjala, Hanna; Koistinen, Tarja; Korhonen, Hannu T. (Finnish Society for Applied Ethology, 2010)Farmed blue foxes utilise a sand floor when it is available. They perform various activities on the sand, e.g. exploration, sniffing, digging and object play. It is unclear, which of the possible activities the foxes use ...
