  1. Application of the welfare quality protocol in pig slaughterhouses of five countries

    Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.

    The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...

  2. Thermographic evaluation of the lower critical temperature in weanling horses

    Contributor(s):: Autio, E., Heiskanen, M. L., Mononen, J.

    Accommodating weanling horses in loose housing (sleeping hall with deep-litter bed and paddock) environments in winter at northern latitudes exposes the nonhuman animals to low ambient temperatures. We determined the heat loss of nine weanling horses in a cold environment by infrared thermography...

  3. Effect of gestation management system on gilt and piglet performance

    Contributor(s):: Muns, R., Manzanilla, E. G., Manteca, X., Gasa, J.

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  4. Effects of two substrate types on the behaviour, cleanliness and thermoregulation of dairy calves

    Contributor(s):: Sutherland, M. A., Stewart, M., Schutz, K. E.

  5. The effect of a view to the surroundings and microclimate variables on use of a loafing area in housed dairy cattle

    Contributor(s):: Haskell, M. J., Maslowska, K., Bell, D. J., Roberts, D. J., Langford, F. M.

  6. 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...

  7. 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...

  8. Roosting behaviour in laying hens on perches of different temperatures: trade-offs between thermoregulation, energy budget, vigilance and resting

    Contributor(s):: Pickel, T., Scholz, B., Schrader, L.

    Laying hens usually select an elevated position for resting at night-time. A previous study showed that the position a hen takes during resting was affected by perch material, most probably due to its thermal conductivity. The aim of the present study was to analyse the effect of perch surface...

  9. A review of the behavioural and physiological adaptations of hill and lowland breeds of sheep that favour lamb survival

    Contributor(s):: Dwyer, C. M., Lawrence, A. B.

    Extensively managed animals, often living in harsh and unfavourable environments, need specific adaptations that promote survivability. This is particularly important at parturition and during the neonatal period, when ewe and lamb mortality is highest. To understand the survival adaptations of...

  10. Review of wallowing in pigs: description of the behaviour and its motivational basis

    Contributor(s):: Bracke, M. B. M.

    Wallowing, i.e. coating the body surface with mud, is a natural behaviour of pigs, commonly observed in feral pigs and wild boar, but rarely provided for in current housing systems for domestic pigs. Furthermore, in welfare science the subject has not been receiving much attention. This paper...

  11. Temperature preferences and feed level of the newborn dairy calf

    Contributor(s):: Borderas, F. T., Passille, A. M. B. de, Rushen, J.

    Low temperatures increase mortality of calves but we know little of calves' abilities to thermoregulate. To examine effects of milk feeding level on thermoregulatory behaviour, 27 Holstein calves were housed for 3 d after birth in individual pens fitted with heat lamps at one end to provide a...

  12. The effects of age and sex on pain sensitivity in young lambs

    Contributor(s):: Guesgen, M. J., Beausoleil, N. J., Minot, E. O., Stewart, M., Jones, G., Stafford, K. J.

    Lambs routinely undergo painful husbandry procedures including ear tagging, tail docking and castration. Pain early in life is important because it can compromise lamb welfare. Studies of altricial species, such as rodents and humans, suggest that baseline pain sensitivity varies with age and...

  13. Winter range use by cattle of different ages in southwestern Montana

    Contributor(s):: Beaver, J. M., Olson, B. E.

    During two winters (1993/94 and 1994/95), the use of winter range by young (3-year-old) cattle that had no experience on winter range was compared with mature (7- to 8-year-old) cattle that had experience on winter range. Ten 3-year-old cows were alternated weekly with ten 7- to 8-year-old cows...

  14. Comparison of the thermoregulatory behaviours of low and high producing dairy cows in a hot environment

    Contributor(s):: Tapk, I., Sahin, A.

    This study was carried out to compare the thermoregulatory behaviours of low and high producing dairy cows in a hot environment. Forty-one Holstein Friesian cows in their first lactation were allocated to two groups (n=21 for group 1, n=20 for group 2) on the basis of their milk production: low...

  15. Observations on disease-associated preferred body temperatures in reptiles

    Contributor(s):: Warwick, C.

    Case studies of disease in reptiles held privately and in other collections over a 12-year period implied that while behaviourally thermoregulated, and imposed, warmer temperatures appeared often to assist recovery; in other cases imposed warmer temperatures accelerated the disease, resulting in...

  16. The use of a heated floor area by sows and piglets in farrowing pens

    Contributor(s):: Pedersen, L. J., Malmkvist, J., Jorgensen, E.

    Twenty-six sows housed in farrowing pens were observed from 5 days prior to until 5 days after parturition. Pens consisted of a resting area with solid concrete floor and an activity area with drained concrete floor. The sows were randomly distributed between two pen types: Pens where the floor...

  17. The use of water-cooled roosts by hens for thermoregulation

    Contributor(s):: Muiruri, H. K., Harrison, P. C., Gonyou, H. W.

    Experiments were conducted to determine whether hens would use water-cooled roosts for thermoregulation during exposure to high ambient temperatures. In the first experiment 8 groups of broiler breeder hens were tested in 25 +or- 1 and 35 +or- 1 degrees C ambient environments. Each group had...

  18. Thermal behaviour of growing pigs in response to high temperature and humidity

    Contributor(s):: Huynh, T. T. T., Aarnink, A. J. A., Gerrits, W. J. J., Heetkamp, M. J. H., Canh, T. T., Spoolder, H. A. M., Kemp, B., Verstegen, M. W. A.

    The effects of high ambient temperatures and humidities on thermal behavioural adaptation and pen fouling of group-housed growing pigs were assessed. Twelve groups of 10 gilts of an average initial body weight (BW) of 61.7 kg were used. During nine experimental days, ambient temperatures were...

  19. Motivation in relation to the welfare of enclosed livestock

    Contributor(s):: Dellmeier, G. R.

  20. Thermoregulatory behaviour of sheep housed in insulated and uninsulated buildings

    Contributor(s):: Boe, K.

    This study was made to investigate the thermoregulatory behaviour of sheep in confinement. In Experiment 1, two groups of 8 lambs in both an insulated (IN) and uninsulated (UN) house (total 32 animals) were studied; the durations of lying with and without body contact and standing were recorded...
