  1. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

  2. Straw applications in growing pigs: effects on behavior, straw use and growth

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    The short-term effects of four straw applications on pigs housed on slatted floors were investigated to determine differences in behavior, straw use and growth. Both the type of straw used and the design of the application might influence the attractiveness and effectiveness of the applications....

    Contributor(s):: Stefanowska, J., Swierstra, D., Braam, C. R., Hendriks, M. M. W. B.

    The objective of this study was to compare the behaviour of cows on a grooved floor with that of cows kept on a slatted floor. The trial was carried out with 2 groups of 12 Holstein-Friesian cows kept in a cowshed with 2 symmetrical halves, identical except for the floor. One floor was grooved...

  9. Effect of a synthetic plate in the lying area on lying behaviour, degree of fouling and skin lesions at the leg joints of finishing pigs

    | Contributor(s):: Savary, P., Gygax, L., Wechsler, B., Hauser, R.

    Flooring type may have a major influence on thermoregulatory behaviour in finishing pigs, as well as on the occurrence of skin lesions at their leg joints and pen fouling. In this study, we compared the lying behaviour, pen fouling and the occurrence of leg lesions in finishing pigs kept in...

  10. Effects of feed- and water-based enrichment on activity and cannibalism in Muscovy ducklings

    | Contributor(s):: Riber, A. B., Mench, J. A.

    Cannibalism is a major problem for commercial production of Muscovy ducks (Cairina moschata). Surprisingly little is known about the ontogeny of cannibalism in ducks or how to reduce/prevent the problem in a welfare-friendly way. The preventative method typically used by the industry is...

  11. Feather eating in layer pullets and its possible role in the aetiology of feather pecking damage

    | Contributor(s):: McKeegan, D. E. F., Savory, C. J.

    Feather eating and its possible relationship with damaging pecking was examined in 144 pen-housed ISA Brown layer pullets. Collection and measurement of loose feathers in sample plots on 12 pen floors (feather were characterized as 'short' or 'long'), and examination of faecal droppings (eaten...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. Resting and social behaviour of dairy heifers housed in slatted floor pens with different sized bedded lying areas

    | Contributor(s):: Nielsen, L. H., Mogensen, L., Krohn, C., Hindhede, J., Sorensen, J. T.

    The hypothesis that an increase in the straw bedded resting area for group housed heifers would increase synchronization of resting behaviour and decrease aggressive and abnormal behaviour was tested. An experiment was conducted on 2 Danish commercial dairy farms with 20 Danish Friesian heifers...

  17. A flooring comparison: the impact of rubber mats on the health, behavior, and welfare of group-housed sows at breeding

    | Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Richert, B. T., Pajor, E. A.

    Comfortable flooring may impact many aspects of an animal's welfare, including lying behavior, an animal's ability to change postures, and incidence of lameness and lesions. Therefore, we hypothesized that the addition of rubber mats to stalls of group pens would improve sow health, comfort and...
