  1. Assessing animal welfare in a strictly synchronous production system: the mink case

    Contributor(s):: Moller, S. H., Hansen, S. W., Sorensen, J. T.

    Most on-farm welfare assessment systems have been developed for use in dairy and pig farms. These production systems are non-synchronous, in the sense that the same processes occur continuously throughout the year. Animal welfare during most or all phases of production may therefore be assessed...

  2. Association between resting behaviour and live weight gain in dairy heifers housed in pens with different space allowance and floor type

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

    The hypothesis that daily liveweight gain is associated with resting behaviour in heifers was studied. The study was based on 2 experiments conducted on Danish commercial dairy farms with Danish Friesian heifers (300-400 kg) in the winter periods. Group size was 5-6 heifers/pen. Experiment A,...

  3. Availability and use of designated hospital pens in Danish dairy herds

    Contributor(s):: Houe, H., Thomsen, P. T., Amdi, C., Herskin, M. S., Forkman, B., Jensen, M. B.

    The objective of this study was to describe the availability and use of designated hospital pens in Danish dairy herds and to analyse the association between availability and use of hospital pens and the herd-level incidence of reported disease treatments. Hospital pens were divided into either...

  4. Behaviour of dairy cows kept in extensive (loose housing/pasture) or intensive (tie stall) environments. III. Grooming, exploration and abnormal behaviour

    Contributor(s):: Krohn, C. C.

    24 pairs of monozygotic twin dairy cows (Danish Friesian and Red Danish) were assigned to 4 groups of 12 in a balanced incomplete-block design. Group E: loose housing; ad lib. access to feeding table; deep bedding; a yard and pasture; and milking twice a day. Group N: tie stall; concrete floor...

  5. Expert consultation on weighting factors of criteria for assessing environmental enrichment materials for pigs

    Contributor(s):: Bracke, M. B. M., Zonderland, J. J., Bleumer, E. J. B.

    EC directive 2001/93/EC states that pigs must have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities. This directive requires further interpretation. In order to facilitate the further implementation of the directive into national,...

  6. Expert judgement on enrichment materials for pigs validates preliminary RICHPIG model

    Contributor(s):: Bracke, M. B. M., Zonderland, J. J., Bleumer, E. J. B.

    EC directive 2001/93/EC states that pigs must have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities. This directive requires further interpretation. In order to facilitate the further implementation of the directive into national,...

  7. Grouping horses according to gender - effects on aggression, spacing and injuries

    Contributor(s):: Jorgensen, G. H. M., Borsheim, L., Mejdell, C. M., Sondergaard, E., Boe, K. E.

    Many horse owners tend to group horses according to gender, in an attempt to reduce aggressive interactions and the risk of injuries. The aim of our experiment was to test the effects of such gender separation on injuries, social interactions and individual distance in domestic horses. A total of...

  8. Health and welfare in Danish dairy cattle in the transition to organic production: problems, priorities and perspectives

    Contributor(s):: Vaarst, M., Alban, L., Mogensen, L., Milan, S., Thamsborg, Kristensen, E. S.

    During the past few years, organic dairy farming has grown dramatically in Denmark. Consequently, an increasing number of people are encountering this method of production for the first time. Amongst these, many veterinarians have suddenly had to deal with organic herds in their home district,...

  9. Living with cat and dog increases vaginal colonization with E. coli in pregnant women

    Contributor(s):: Stokholm, J., Schjorring, S., Pedersen, L., Bischoff, A. L., Folsgaard, N., Carson, C. G., Chawes, B., Bonnelykke, K., Molgaard, A., Krogfelt, K. A., Bisgaard, H.

  10. Long-stemmed straw as an additional nesting material in modified Schmid pens in a commercial breeding unit: effects on sow behaviour, and on piglet mortality and growth

    Contributor(s):: Damm, B. I., Pedersen, L. J., Heiskanen, T., Nielsen, N. P.

    The aim of this study was to determine whether provision of nest materials in a form and amount that could be handled in a commercial Danish pig farm with modified Schmid pens would affect the environment for sows and piglets to an extent that could be detected in sow behaviour and parameters...

  11. Oestrus and mating behaviour in gilts during boar induced puberty in relation to stress and housing

    Contributor(s):: Pedersen, L. J., Jensen, K. H., Giersing Linder, A.

    The effect of intermittent electroshock and individual vs. pair housing on sexual proceptive behaviour was studied in 48 large White x Danish Landrace gilts. In addition, the effect of intermittent electroshock on the behavioural response to boar stimulation and on sexual receptivity during first...

  12. Play behaviour in group-housed dairy calves, the effect of space allowance

    Contributor(s):: Jensen, M. B., Kyhn, R.

    96 Danish Holstein Friesian calves in 6 repetitions were housed in groups of 4, in pens of either 4, 3, 2.2 or 1.5 msuperscript 2 per calf from 2 weeks of age. The occurrence of play behaviour in the home environment was recorded continuously for each individual calf during 24 h at 5, 7 and 9...

  13. 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...

  14. Selection of Meat Inspection Data for an Animal Welfare Index in Cattle and Pigs in Denmark

    Contributor(s):: Katie Osborn, Soren Saxmose Nielson, Matthew James Denwood, Bjorn Forkman, Hans Houe

    Despite being important to the general public, the monitoring of animal welfare is not systematic. The Danish political parties agreed in 2012 to establish national animal welfare indices for cattle and pigs, and here we assess the potential for using data from the systematic meat inspection to...

  15. Size, design and interspecific interactions as restrictors of natural behaviour in multi-species exhibits. 1. Activity and intraspecific interactions of Plains zebra ( Equus burchelli )

    Contributor(s):: Andersen, K. F.

    Three herds of Plains zebras in multi-species pounds in 3 Danish zoos were studied during spring/summer of 1989. Pounds varied greatly in size: Copenhagen Zoo - 0.5 ha, grassless; Loveparken Zoo Givskud - 5 ha, short grass; Knuthenborg Safari Park - 18 ha, long grass. A 10 min scan of activity,...
