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...

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...

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...

Differential effects of increased stocking density, mediated by increased flock size, on feather pecking and aggression in laying hens
Contributor(s):: Nicol, C. J., Gregory, N. G., Knowles, T. G., Parkman, I. D., Wilkins, L. J.
Six flocks of laying hens were housed in percheries at 4 stocking densities (6, 14, 22 or 30 birds m-2) from 14 to 30 weeks of age. Stocking density was manipulated by changes in flock size (72, 168, 264 or 368 birds) in percheries with the same floor and height dimensions. The pecking behaviour...
Effect of manipulating feathers of laying hens on the incidence of feather pecking and cannibalism
Contributor(s):: McAdie, T. M., Keeling, L. J.
Feather pecking was studied in 16 groups of 11 Lohmann Brown hens between 26 and 28 weeks of age. The feather pecks were classified separately as either gentle or severe. Damaged feathers received significantly more severe feather pecks than undamaged feathers. There were also more gentle feather...
Mating behavior of bucks and does in goat operations under range conditions
Contributor(s):: Mellado, M., Cardenas, C., Ruiz, F.
The objectives of this study were to characterize the mating capacity of bucks under range condition and assess the effect of mating frequency on flock fertility. Two adjacent flocks of crossbred goats (Criollo x dairy goat breeds; n = 70 does, 5 bucks and 141 does, 4 bucks) were used. The mating...
Space use and agonistic behaviour in relation to sex composition in large flocks of laying hens
Contributor(s):: Oden, K., Vestergaard, K. S., Algers, B.
Experiments were carried out to test the hypothesis that hens in large flocks have home ranges in parts of the pen and that they form subgroups. In a tiered aviary system (density averaged 16 hens/msuperscript 2 of floor area), 8 flocks of 568+or-59 ISA Brown laying hybrids were kept in pens....
The risk factors affecting the development of gentle and severe feather pecking in loose housed laying hens
Injurious pecking remains one of the biggest problems challenging free range egg producers, with both economic implications for the farmer and welfare implications for the birds. The most widespread form of injurious pecking is feather pecking, the most damaging form of which is severe feather...
Influence of farm factors on the occurrence of feather pecking in organic reared hens and their predictability for feather pecking in the laying period
Contributor(s):: Bestman, M., Koene, P., Wagenaar, J. P.
Feather pecking is one of the most obvious welfare problems in laying hens. It is seen in all types of housing systems. Although banned in some countries, beak trimming is generally used to reduce the damage caused by this behaviour. In organic farming, where beak trimming is prohibited, the...
