Sheep farmer opinions on the current and future role of veterinarians in flock health management on sheep farms: a qualitative study
Contributor(s):: Jasmeet Kaler, L.E. Green
A 2009 UK Government report on veterinary expertise in food animal production highlighted that there was insufficient herd health expertise among veterinarians and lack of appropriate business models to deliver veterinary services to the livestock sector. Approximately two thirds of sheep farmers...
On-farm qualitative behaviour assessment in sheep: repeated measurements across time, and association with physical indicators of flock health and welfare
Contributor(s):: Phythian, C. J., Michalopoulou, E., Cripps, P. J., Duncan, J. S., Wemelsfelder, F.
Qualitative Behavioural Assessment (QBA) is a 'whole-animal' methodology that assesses the expressive qualities of animal behaviour using terms such as 'tense', 'relaxed', 'anxious', and 'content'. The reliability and validity of QBA as an indicator for on-farm welfare assessment in pigs, cattle,...

Farmer attitudes to injurious pecking in laying hens and to potential control strategies
Contributor(s):: Palczynski, L. J., Buller, H., Lambton, S. L., Weeks, C. A.
Farmers' recognition of health and welfare problems, and their responses to related intervention programmes, such as those to reduce injurious pecking in hens, directly influence the welfare of animals in their care. Changing those responses can be achieved through a re-positioning of social...
Tree cover and injurious feather-pecking in commercial flocks of free-range laying hens: a follow up
Contributor(s):: Bright, A., Gill, R., Willings, T. H.
Injurious feather-pecking in non-cage systems is a serious economic and welfare concern for the egg-producing industry. This study presents results from data of over 1,000 flocks from producers who supplied free-range eggs to McDonald's Restaurants Ltd UK between 2008 and 2013. These producers...
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...
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...
The risk factors affecting the development of vent pecking and cannibalism in free-range and organic laying hens
Contributor(s):: Lambton, S. L., Knowles, T. G., Yorke, C., Nicol, C. J.
Injurious pecking remains one of the biggest animal welfare and economic challenges for free-range egg producers. This prospective epidemiological study investigated the development of vent pecking (VP) and cannibalism on 62 free-range and organic UK farms (119 flocks). Flocks were visited at 25...
Predicting feather damage in laying hens during the laying period. Is it the past or is it the present?
Contributor(s):: Haas, E. N. de, Bolhuis, J. E., Jong, I. C. de, Kemp, B., Janczak, A. M., Rodenburg, T. B.
Feather damage due to severe feather pecking (SFP) in laying hens is most severe during the laying period. However, SFP can develop at an early age and is influenced by early rearing conditions. In this study we assessed the risk factors during the rearing and laying period for feather damage at...

Changes in substrate access did not affect early feather-pecking behavior in two strains of laying hen chicks
Contributor(s):: Dixon, L. M., Duncan, I. J. H.
Feather pecking, commonly found in flocks of laying hens (Gallus gallus), is detrimental to bird welfare. Thought to cause this problem is the normal housing of layers without a floor substrate. Some evidence suggests that early substrate access decreases later feather pecking. However, there has...
Use of outdoor ranges by laying hens in different sized flocks
Contributor(s):: Gebhardt-Henrich, S. G., Toscano, M. J., Frohlich, E. K. F.
In studies assessing outdoor range use of laying hens, the number of hens seen on outdoor ranges is inversely correlated to flock size. The aim of this study was to assess individual ranging behavior on a covered (veranda) and an uncovered outdoor run (free-range) in laying hen flocks varying in...
