Welfare outcomes for 3- and 6-month-old beef calves in a tropical environment castrated surgically or by applying rubber rings
Contributor(s):: Petherick, J. C., Small, A. H., Reid, D. J., Colditz, I. G., Ferguson, D. M.
Castration of cattle using rubber rings is becoming increasingly popular due to the perceived ease of the procedure and greater operator safety when compared with surgical castration. Few comparative studies have investigated the effects of different castration methods and calf age on welfare...
Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing
Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.
Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...
Plumage damage in free-range laying hens: behavioural characteristics in the rearing period and the effects of environmental enrichment and beak-trimming
Contributor(s):: Hartcher, K. M., Tran, M. K. T. N., Wilkinson, S. J., Hemsworth, P. H., Thomson, P. C., Cronin, G. M.
Severe feather-pecking, whereby birds peck at and pull out the feathers of other birds, is one of the greatest welfare concerns and the most prevalent behavioural problem in laying hens. It can be extremely difficult to control, especially in non-cage laying flocks. Despite a multitude of studies...

Behaviour and leg injuries in dairy cows kept in cubicle systems with straw bedding or soft lying mats
Contributor(s):: Wechsler, B., Schaub, J., Friedli, K., Hauser, R.
In order to reduce straw input, soft lying mats are used increasingly instead of straw bedding in cubicle systems for dairy cows. This study aimed at comparing different types of soft lying mats with straw bedding regarding cow behaviour and leg injuries. Data were collected on 5 farms with straw...
Development with age of nest box use and gregarious nesting in laying hens
Contributor(s):: Riber, A. B.
Use of nest boxes is an important part of the behavioural repertoire of laying hens kept under commercial conditions. A special form of nest box use is gregarious nesting, which occurs when a hen given the choice between an occupied and an unoccupied nest site chooses the occupied nest site....
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...
Partial tooth-clipping of suckling pigs: effects on neonatal competition and facial injuries
Contributor(s):: Weary, D. M., Fraser, D.
Two experiments investigated the effects on facial injury and piglet performance of partial clipping of needle teeth, whereby only the distal third of the tooth is removed. In experiment 1, teeth were partially clipped, fully clipped to the gum line, or left intact. All piglets of a litter...
Effect of gestation housing on behaviour and skin lesions of sows in farrowing crates
Contributor(s):: Boyle, L. A., Leonard, F. C., Lynch, P. B., Brophy, P.
Group housing systems for pregnant sows are set to become more popular, but there is evidence that this development could influence the welfare of sows in farrowing crates. A study was designed to assess the effect of gestation accommodation on behaviour, welfare and farrowing performance of sows...
Group housing of adult silver fox ( Vulpes vulpes ) vixens during autumn and its consequences for body weight, injuries and later reproduction: a field study
Contributor(s):: Hovland, A. L., Bakken, M.
Usually, farmed silver foxes are housed singly throughout adulthood. Due to the flexible social nature of wild foxes social grouping may act as an alternative housing procedure for adult vixens. However, sociality may involve increased levels of aggression during competition for e.g. dominance...
Social interactions of unfamiliar horses during paired encounters: effect of pre-exposure on aggression level and so risk of injury
Contributor(s):: Hartmann, E., Christensen, J. W., Keeling, L. J.
Group housing of horses is not widely applied in practice despite the welfare advantages of keeping animals socially rather than individually. In particular, concerns have been raised about the possible increased risk of injury and how to introduce a new horse into an established group. This...
