  1. Social networks and welfare in future animal management

    Contributor(s):: Koene, P., Ipema, B.

    It may become advantageous to keep human-managed animals in the social network groups to which they have adapted. Data concerning the social networks of farm animal species and their ancestors are scarce but essential to establishing the importance of a natural social network for farmed animal...

  2. Attitudes of veterinary students in Croatia toward farm animal welfare

    Contributor(s):: Ostovic, M., Mesic, Z., Mikus, T., Matkovic, K., Pavicic, Z.

    This survey was undertaken to assess the attitudes of Croatian veterinary students regarding farm animal welfare issues. The study included students of all undergraduate years at the only Faculty of Veterinary Medicine in Croatia. First-year students were surveyed twice, ie before and after...

  3. 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...

  4. Effects of carprofen, meloxicam and butorphanol on broiler chickens' performance in mobility tests

    Contributor(s):: Hothersall, B., Caplen, G., Parker, R., Nicol, C. J., Waterman-Pearson, A. E., Weeks, C. A., Murrell, J. C.

    Lame broiler chickens perform poorly in standardised mobility tests and have nociceptive thresholds that differ from those of non-lame birds, even when confounding factors such as differences in bodyweight are accounted for. This study investigated whether these altered responses could be due to...

  5. 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...

  6. Consumer attitudes to injurious pecking in free-range egg production

    Contributor(s):: Bennett, R. M., Jones, P. J., Nicol, C. J., Tranter, R. B., Weeks, C. A.

    Free-range egg producers face continuing problems from injurious pecking (IP) which has financial consequences for farmers and poor welfare implications for birds. Beak-trimming has been practised for many years to limit the damage caused by IP, but with the UK Government giving notification that...

  7. The contribution of broiler chicken welfare certification at farm level to enhancing overall animal welfare: the case of Brazil

    Contributor(s):: Souza, A. P. O., Molento, C. F. M.

    The intensification of farm animal welfare debate has led to an increasing number of certification schemes covering this issue; however, there are concerns about the contribution of these schemes in improving welfare. The aims of this study were to identify certification schemes for broiler...

  8. Behavioural consequences of visual deprivation occurring at hatch or in the early life of chickens

    Contributor(s):: Hocking, P. M., Haldane, K. A., Davidson, E. M., Sandoe, P., Kristensen, H. H.

    The development of behaviour in a line of chickens that are born sighted ( rdd) but turn blind after hatching was compared with a line that is blind at hatch ( beg) and with sighted White Leghorn controls (WL) to test the hypothesis that birds that become blind later in their life will show...

  9. Dustbathing, pecking and scratching behaviours of laying hens in furnished cages are enhanced by the presence of rubber mats and litter distribution

    Contributor(s):: Guinebretiere, M., Michel, V., Arnould, C.

    Furnished cages for laying hens exist in a wide variety of sizes and designs and should be equipped to allow hens to express some of their behavioural priorities. European Council Directive 1999/74/EC stipulates that litter must be provided for pecking and scratching but the type of litter and...

  10. Effects of maternal vocalisations on the domestic chick stress response

    Contributor(s):: Edgar, J., Kelland, I., Held, S., Paul, E., Nicol, C.

    Although natural brooding is not commercially feasible, there is great potential to simulate aspects of maternal care to improve the welfare of farmed domestic chicks. Our previous studies showed that the presence of calm broody hens can buffer mild stress responses in chicks, although the...

  11. Mate choice, maternal investment and implications for ostrich welfare in a farming environment

    Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.

    At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...

  12. Moral "lock-in" in responsible innovation: the ethical and social aspects of killing day-old chicks and its alternatives

    Contributor(s):: Bruijnis, M. R. N., Blok, V., Stassen, E. N., Gremmen, H. G. J.

    The aim of this paper is to provide a conceptual framework that will help in understanding and evaluating, along social and ethical lines, the issue of killing day-old male chicks and two alternative directions of responsible innovations to solve this issue. The following research questions are...

  13. Effects of variation in nest curtain design on pre-laying behaviour of domestic hens

    Contributor(s):: Ringgenberg, N., Frohlich, E. K. F., Harlander-Matauschek, A., Toscano, M. J., Wurbel, H., Roth, B. A.

    Laying hens in loose-housing systems select a nest daily in which to lay their eggs among many identical looking nests, they often prefer corner nests. We investigated whether heterogeneity in nest curtain appearance - via colours and symbols - would influence nest selection and result in an even...

  14. 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...

  15. Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age

    Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.

    Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...

  16. Dustbathing behavior: do ectoparasites matter?

    Contributor(s):: Vezzoli, G., Mullens, B. A., Mench, J. A.

    A presumed function of dustbathing behavior is to remove ectoparasites. Providing dustbathing substrates in furnished cages for laying hens might therefore offer an alternative to pesticide use to reduce ectoparasite populations. We investigated the effectiveness of dustbathing substrates for...

  17. Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females

    Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.

    An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...

  18. Farm animal welfare and children: a preliminary study building an attitude scale and evaluating an intervention

    Contributor(s):: Lakestani, N., Aguirre, V., Orihuela, A.

    Children are future consumers; they will impact future animal welfare standards. This pilot study evaluated a nonhuman animal welfare education program, building a farm animal attitude questionnaire for 8- to 10-year-old children. The educational material focused on the behaviors and needs of...

  19. Nest choice in laying hens: effects of nest partitions and social status

    Contributor(s):: Ringgenberg, N., Frohlich, E. K. F., Harlander-Matauschek, A., Toscano, M. J., Wurbel, H., Roth, B. A.

    Nest choice in loose-housed laying hens is influenced by nest characteristics, position and social factors. We examined the relative preference of laying hens for two group-nests differing in the presence or absence of a partition in the middle of the nest and whether this was influenced by...

  20. Perseveration in a guessing task by laying hens selected for high or low levels of feather pecking does not support classification of feather pecking as a stereotypy

    Contributor(s):: Kjaer, J. B., Wurbel, H., Schrader, L.

    Feather pecking is a behaviour by which birds damage or destroy the feathers of themselves (self-pecking) or other birds (allo feather pecking), in some cases even plucking out feathers and eating these. The self-pecking is rarely seen in domestic laying hens but is not uncommon in parrots....
