Positive affective state induced by opioid analgesia in laying hens with bone fractures
Contributor(s):: Nasr, M. A. F., Browne, W. J., Caplen, G., Hothersall, B., Murrell, J. C., Nicol, C. J.
Laying hens with keel fractures (n=35) and control hens with no fractures (n=12) were trained to associate the colour and position of an environment with the effects of either a subcutaneous injection of an opioid analgesic drug (butorphanol) or a subcutaneous injection of saline in a conditioned...
The effect of experience of ramps at rear on the subsequent ability of layer pullets to negotiate a ramp transition
Contributor(s):: Norman, Kate I., Weeks, Claire A., Pettersson, Isabelle C., Nicol, Christine J.
In commercial situations, laying hens must negotiate levels to reach resources such as food, water and litter. Providing ramps in aviary systems reduces collisions and resultant keel bone fractures in adults. We investigated whether providing ramps during rear improved the ability of birds to...
Case–Control Study of Hazards in the Home and Risk of Falls and Hip Fractures
out of 5 stars
| Contributor(s):: Lindy Clemson, Robert G. Cumming, Maryanne Roland
The importance of environmental hazards in the home as risk factors for falls and fractures is uncertain. A case–control study was conducted, involving people aged 65 years and over referred to an occupational therapy department for home assessment. There were 52 subjects with a recent...
Understanding past human-animal relationships through the analysis of fractures: a case study from a Roman site in the Netherlands
| Contributor(s):: Maaike Groot
In studying fractures in archaeology, we should focus on what they can tell us about human-animal relationships. It is important to show other (zoo-) archaeologists that palaeopathology can be a valuable tool in answering (zoo-) archaeological questions. In this paper, a short summary of fracture...
Effects of catching and transportation versus pre-slaughter handling at the abattoir on the prevalence of wing fractures in broilers
| Contributor(s):: Kittelsen, K. E., Granquist, E. G., Vasdal, G., Tolo, E., Moe, R. O.
Fractures occurring in conscious broiler chickens are painful and severely compromise animal welfare. The aim of this study was to investigate the effects of pre-slaughter handling procedures on the frequency of wing fractures. Wings were examined for fractures in 11,609 broilers, from 12...
Modification of aviary design reduces incidence of falls, collisions and keel bone damage in laying hens
| Contributor(s):: Stratmann, A., Frohlich, E. K. F., Gebhardt-Henrich, S. G., Harlander-Matauschek, A., Wurbel, H., Toscano, M. J.
Non-cage housing systems for laying hens such as aviaries provide greater freedom to perform species-specific behavior and thus are thought to improve welfare of the birds; however, aviaries are associated with a high prevalence of keel bone damage (fractures and deviations), which is a major...

The husbandry, welfare and health of captive African civets ( Vivera civetica ) in western Ethiopa
| Contributor(s):: Tolosa, T., Regassa, F.
A study was carried out during the period from September 2001 to August 2002 in Jimma zone, western Ethiopia to evaluate the husbandry and health of captive African civets (Vivera civetica). Wild civets were found in the wild in all 13 of the districts in the zone, although traditional...
Welfare assessment of laying hens in furnished cages and non-cage systems: an on-farm comparison
| Contributor(s):: Rodenburg, T. B., Tuyttens, F. A. M., Reu, K. de, Herman, L., Zoons, J., Sonck, B.
From 2012 onwards, all laying hens in Europe will need to be housed either in furnished cages or non-cage systems (aviaries or floor-housing systems). In terms of animal welfare, furnished cages and non-cage systems both have advantages and disadvantages. Data on direct comparisons between the...
