  1. Behavioural diversity as a measure of welfare: a study in pigs

    Contributor(s):: Hirt, H., Wechsler, B.

  2. Choices of laboratory rabbits for individual or group-housing

    Contributor(s):: Held, S. D. E., Turner, R. J., Wootton, R. J.

    Groups of adult rabbits in which stable dominance hierarchies had been developed were used in the experiments. In experiment one, 9 low-ranking and 9 high-ranking rabbits were given the choice between a group-pen and a solitary pen; the solitary pen was the same size (2.8 msuperscript 2) and had...

  3. Comparison of daytime use between platform types, materials, ceilings and experiences in juvenile blue foxes ( Alopex lagopus )

    Contributor(s):: Korhonen, H., Ketoja, E., Niemela, P.

    264 juvenile blue foxes were housed in cages with side-U platforms or corner flat platforms made from wood or net with ceilings 23 or 30 cm above. The foxes were the offspring of females housed in cages without or with platforms. Platform type significantly affected the amount of time the foxes...

  4. Discrimination by hens in favour of litter rather than wire floors?

    Contributor(s):: Hughes, B. O., Duncan, I. J. H.

    In discussing a previous paper (Lagadic, H. and Faure, J.M. (1987) Applied Animal Behaviour Science 19, 147-155), the authors suggest a different conclusion in relation to the preferences of hens for more space and access to litter.

  5. Diurnal behavior patterns of cage-reared Brown Tsaiya ducks ( Anas platyrhynchos var. domestica )

    Contributor(s):: Lee, S. R., Lee, Y. P., Chen, B. J.

    Two batches of Brown Tsaiya ducks, 184 female ducks in each, were studied for diurnal behaviour patterns and acclimatization to cage environment. Ducks were housed in individual cages at 14 weeks old. Video recordings were taken for 6 consecutive days at 25, 35, 45 and 55 weeks of age, and every...

  6. Effect of rearing density on pecking behaviour and plumage condition of laying hens in two types of aviary

    Contributor(s):: Hansen, I., Braastad, B. O.

    Chicks were reared on sand at high (H; 13/msuperscript 2) or low (L; 6.5/msuperscript 2) density, in 4 rearing pens of 390 chicks and 8 pens of 195 chicks, respectively, each pen measuring 30 msuperscript 2. Proportions of chicks per pen performing various types of pecking behaviour were recorded...

  7. Effects of confinement on social interaction patterns in dry sows

    Contributor(s):: Jensen, P.

    Studies were carried out in 3 different herds, representing 3 different housing systems. In the first system (de-confinement), the animals were housed in groups of 5, with individual feeding stalls, a common dunging area and a common lying box (net floor area, 3.04 msuperscript 2/sow), in the...

  8. Effects of group house rearing on the behaviour and performance of fattening pigs

    Contributor(s):: Geismar, J.

  9. Effects of regular handling and exposure to an outside area on subsequent fearfulness and dispersal in domestic hens

    Contributor(s):: Grigor, P. N., Hughes, B. O., Appleby, M. C.

    The effects of regular handling and/or exposure to the outside environment on immature laying hens' fear levels and subsequent readiness to disperse in an outdoor area were investigated. 56 birds, 12 to 20 weeks old, were subjected to (1) no handling plus no outdoor experience (control); (2)...

  10. Effects of social environment on welfare status and sexual behaviour of female pigs. II. Effects of space allowance

    Contributor(s):: Hemsworth, P. H., Barnett, J. L., Hansen, C., Winfield, C. G.

    This study examined the effects of housing groups of adult female pigs (6 pigs per group) with a space allowance of 1, 2 or 3 msuperscript 2 per pig on sexual behaviour and welfare status, determined by plasma free-corticosteroid concentrations. A lower percentage of gilts was detected in oestrus...

  11. Emergence and dispersal behaviour in domestic hens: effects of social rank and novelty of an outdoor area

    Contributor(s):: Grigor, P. N., Hughes, B. O., Appleby, M. C.

    Groups of laying hens, were placed in covered boxes with a feeder inside the box, 1 m outside the box, or 2 feeders, 1 inside and 1 out. The time taken for hens to emerge from the box was recorded. Hens emerged earlier when the feeder was outside rather than inside the box. Social rank within the...

  12. Factors affecting the choice of farrowing site in sows

    Contributor(s):: Haskell, M. J., Hutson, G. D.

    Three experiments were carried out in a 6.5 m x 7 m test arena with a 2 m x 2 m pen in one corner. Sows were observed individually for 8 h/day from 4 days before farrowing was due, until farrowing actually occurred. Sows were fed 2.2 kg/day of a standard sows diet. In experiment 1, 6 multiparous...

  13. Fearfulness of caged laying hens: the effects of cage level and type of roofing

    Contributor(s):: Jones, R. B.

    The responses of individually caged, adult laying fowls to 2 fear-eliciting test situations were assessed as a function of housing in (a) the top or middle tiers of a 3-tier battery system, and (b) cages roofed with wire-mesh or sheet metal. Previous reports of higher fearfulness among top-tier...

  14. Feeder design and available feeding space influence the feeding behaviour of hens

    Contributor(s):: Huon, F., Menuier-Salaun, M. C., Faure, J. M.

    The effects of 8 feeder designs and available feeding space were examined in 15 groups of 3 laying hens in deep litter pens. Feeding rates and the number of feeding bouts were higher, feed consumption lower and duration of feeding shorter in partitioned than unpartitioned feeders. Feeding times...

  15. Incidence of oestrus and oestrous trends in lactating sows housed in different social and physical environments

    Contributor(s):: Henderson, R., Stolba, A.

    Lactating sows were kept in conventional farrowing crates, larger pens with outside yards, or family pens for sows and progeny up to 60 kg body weight. Additional treatments, allowing contact with other sows and/or boars and restricted piglet contact, were applied to some sows. Various...

  16. Influence of environmental stimuli on maternal behaviour related to bonding, reactivity and crushing of piglets in domestic sows

    Contributor(s):: Herskin, M. S., Jensen, K. H., Thodberg, K.

    Effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined in a 2 x 2 factorial experiment with 9 replicates of 4 multiparous sows. From one week prepartum until 13-15 days postpartum, sows were kept individually in 'get-away pens' with a 7.6...

  17. Inter-individual distances and orientation in laying hens housed in groups of three in two different-sized enclosures

    Contributor(s):: Keeling, L. J., Duncan, I. J. H.

    Groups of 3 hens were placed in pens of two different sizes (0.65x0.65 and 1.3x1.3 m) and the locations of individuals were determined using overhead time-lapse photography. The birds did not use the areas evenly. Hens in the small pen tended to use the corners, whereas the centre of the large...

  18. Inventory of the behaviour of New Zealand White rabbits in laboratory cages

    Contributor(s):: Gunn, D., Morton, D. B.

  19. Perch use, plumage and foot condition and bone strength in caged hens

    Contributor(s):: Hughes, B. O., Appleby, M. C.

  20. Preferences of domestic hens for cage size and floor types as measured by operant conditioning

    Contributor(s):: Lagadic, H., Faure, J. M.

    Five groups of 4 hens were trained to increase the size of their cage by means of key pecking in an operant conditioning apparatus. Cage sizes could be varied between 1600 and 6100 cmsuperscript 2. The cage floor could be either wood shavings or wire mesh. Hens spent approximately 50% of their...
