  1. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  2. Changes in substrate access did not affect early feather-pecking behavior in two strains of laying hen chicks

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

    Feather pecking, commonly found in flocks of laying hens (Gallus gallus), is detrimental to bird welfare. Thought to cause this problem is the normal housing of layers without a floor substrate. Some evidence suggests that early substrate access decreases later feather pecking. However, there has...

  3. Effect of enclosure size and complexity on the behaviors of captive chimpanzees ( Pan troglodytes )

    Contributor(s):: Jensvold, M. L. A., Sanz, C. M., Fouts, R. S., Fouts, D. H.

    Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behaviour of 5 adult chimpanzees that coincided with...

  4. Flaws in federal regulations pertaining to the welfare of primates kept in research institutions

    Contributor(s):: Reinhardt, V.

    Federal welfare regulations for primates kept in research laboratories fail to (a) include recommendations pertaining to the legal requirement of the avoidance of stress and unnecessary discomfort during handling procedures, (b) specify how the legally required "uniform illumination" can be...

  5. Welfare, health, and hygiene of laying hens housed in furnished cages and in alternative housing systems

    Contributor(s):: Rodenburg, T. B., Tuyttens, F. A. M., Sonck, B., Reu, K. de, Herman, L., Zoons, J.

    The aim of this review was to compare welfare, health, and hygienic status of laying hens housed in furnished cages and in alternative systems. In alternative systems (floor housing and aviaries), birds have more freedom of movement and a more complex environment than in furnished cages. However,...

  6. Alternative housing systems for fattening bulls under Austrian conditions with special respect to rubberised slatted floors

    Contributor(s):: Rouha-Muelleder, C., Absmanner, E., Kahrer, E., Zeiner, H., Scharl, T., Leisch, F., Stanek, C., Troxler, J.

  7. Foot disorders in dairy cattle: impact on cow and dairy farmer

    Contributor(s):: Bruijnis, M. R. N., Beerda, B., Hogeveen, H., Stassen, E. N.

  8. The welfare of growing pigs in five different production systems in France and Spain: assessment of health

    Contributor(s):: Temple, D., Courboulay, V., Velarde, A., Dalmau, A., Manteca, X.

  9. 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...

  10. Floor temperature preference of sows at farrowing

    Contributor(s):: Phillips, P. A., Fraser, D., Pawluczuk, B.

    A preference testing apparatus was used to provide sows with continuous access to 3 identical farrowing crates, each with a different floor temperature. The concrete floor under each crate contained copper pipe through which temperature-controlled water was circulated to achieve unoccupied floor...

  11. Preference testing in intensively kept meat production rabbits for straw on wire grid floor

    Contributor(s):: Morisse, J. P., Boilletot, E., Martrenchar, A.

    384 hybrid commercial breed rabbits were assigned to 16 pens of 1.6 msuperscript 2 (15 rabbits/msuperscript 2). Eight pens used as controls had an all-wire floor, while in 8 other pens, rabbits could choose between a wire floor or a deep litter topped up once a week and completely replaced once...

  12. Preferences of dairy cows kept in unheated buildings for different kind of cubicle flooring

    Contributor(s):: Manninen, E., Passille, A. M. de, Rushen, J., Norring, M., Saloniemi, H.

    Cubicles with deep straw are widely used in uninsulated cubicle housing for dairy cows, but the problem for many farmers is to obtain sufficient straw. Soft rubber mats or sand bedding may help reduce the use of straw. In Experiment 1 cows' preferences for three types of cubicle flooring were...

  13. Assessment of preference for grid-flooring and sawdust-flooring by captive-bred marmosets in free-standing cages

    Contributor(s):: Hardy, A., Windle, C. P., Baker, H. F., Ridley, R. M.

    Marmosets (Callithrix jacchus) in a captive breeding colony living in metal caging, with wooden shelves and perches, were assessed by video recording for the time spent on the floor of the cage when that floor was a wire grid above a sawdust-filled tray and when it had been changed to a...

  14. Behaviour of two genotypes of growing-finishing pig in three different housing systems

    Contributor(s):: Guy, J. H., Rowlinson, P., Chadwick, J. P., Ellis, M.

    This trial compared the behaviour of 720 growing-finishing pigs, progeny of either indoor (Large White x Landrace) or outdoor (part-Meishan or part-Duroc) sows mated to Large White boars, when housed in either outdoor paddocks, straw yards or fully-slatted pens. Space allowance per pig in outdoor...

  15. Effects of different housing systems on the behaviour of beef bulls - an on-farm assessment on Austrian farms

    Contributor(s):: Absmanner, E., Rouha-Mulleder, C., Scharl, T., Leisch, F., Troxler, J.

    Previous studies noted significant health and behavioural problems in cattle accommodated on fully slatted floors. As the majority of beef bulls in Austria are still housed on fully slatted floors the development of alternative housing systems becomes vitally important. On the basis of...

  16. Effects of two stall flooring systems on the behaviour of tied dairy cows

    Contributor(s):: Hultgren, J.

    Effects on dairy cow behaviour of a new type of flooring in tie-stalls, with the ability to drain faeces and urine, was studied in a controlled randomized trial in one Swedish university herd. Forty-two Swedish Red and White cows were kept tied in traditional long-stalls (2.20 m). In 21 stalls...

  17. Lying characteristics as determinants for space requirements in pigs

    Contributor(s):: Ekkel, E. D., Spoolder, H. A. M., Hulsegge, I., Hopster, H.

    An experiment was carried out to study the lying postures, space occupation and percentage of space-sharing (as a consequence of huddling behaviour) in pigs. Information about these lying characteristics is essential for the calculation of lying space requirements, e.g. for pen design legislative...

  18. Spatial distribution and behaviour of laying hens housed in an alternative system

    Contributor(s):: Channing, C. E., Hughes, B. O., Walker, A. W.

    The spatial distribution and behaviour of perchery housed laying hens were compared at a constant stocking density (18.5 birds/m2) in eight pens with colonies of five different sizes (323 birds (N=1), 374 birds (N=2), 431 birds (N=2), 572 birds (N=1) and 912 birds (N=2)). The birds were placed in...

  19. Floor quality and space allowance in intensive beef production: a review

    Contributor(s):: Wechsler, B.

    In intensive beef production in Europe, finishing beef cattle are typically reared in pens with fully slatted floors and low space allowances. These housing conditions were questioned in a report published by the Scientific Committee on Animal Health and Animal Welfare in 2001. The report...

  20. Factors affecting the welfare of ruminants in livestock farming

    Contributor(s):: Mounier, L., Marie, M., Lensink, B. J.

    Ruminant production is characterized by a large diversity in husbandry systems and management practices that can influence animal welfare. For example, housing conditions are important. In outdoor rearing systems, climate changes can provoke thermal stress and health problems. Indoors, factors...
