    | Contributor(s):: Ting, S. T. L., Earley, B., Veissier, I., Gupta, S., Crowe, M. A.

    The objective was to investigate the effects of Burdizzo castration on the thermal nociception (stress-induced hypoalgesia) of Holstein-Friesian bull calves of different ages. Calves castrated at 5.5 mo of age were compared with either intact calves of the same age, or calves castrated at 1.5,...

  2. Effects of space allowance on the welfare of dry sows kept in dynamic groups and fed with an electronic sow feeder

    | Contributor(s):: Remience, V., Wavreille, J., Canart, B., Meunier-Salaun, M. C., Prunier, A., Bartiaux-Thill, N., Nicks, B., Vandenheede, M.

    The minimal legal space allowance for grouped pregnant sows in the EU is 2.25 m2/sow. The effect of higher space per animal on agonistic behaviour and social stress of animals living in dynamic groups is not known. Two groups of 34 pregnant Belgian Landrace sows were housed in two pens of...

  3. The accumulation of skin lesions and their use as a predictor of individual aggressiveness in pigs

    | Contributor(s):: Turner, S. P., Farnworth, M. J., White, I. M. S., Brotherstone, S., Mendl, M., Knap, P., Penny, P., Lawrence, A. B.

    Post-mixing aggression in commercially housed pigs can be intense and often results in the accumulation of skin lesions. The number of lesions (lesion score, LS) has often been used as a proxy indicator of post-mixing aggression. There has been no previous attempt to quantify the role of...

  4. Observations on behaviour and skin damage of slaughter pigs and treatment during lairage

    | Contributor(s):: Geverink, N. A., Engel, B., Lambooij, E., Wiegant, V. M.

    Slaughterhouse husbandry practice, agonistic behaviour in groups of pigs, indices of skin damage following slaughter (recorded on a relative scale of 1-4 where 4 indicates severe damage) were studied in 5 Dutch and 4 Belgian abattoirs. Variation in slaughterhouse husbandry practice was...

  5. Comparisons of damaging feather pecking and time budgets in male and female turkeys of a traditional breed and a genetically selected male line

    | Contributor(s):: Busayi, R. M., Channing, C. E., Hocking, P. M.

    Feather and skin pecking leading to feather loss and tissue damage is a welfare problem in commercial turkeys. A factorial experiment was designed to compare a line of unselected turkeys that previously did not exhibit this behaviour with a genetically selected male line with a propensity for...

  6. Diet and habitat selection by cattle: the relationship between skin- and gut-defense systems

    | Contributor(s):: Cibils, A. F., Howery, L. D., Ruyle, G. B.

    Animals possess an external or skin-defense system that protects them from aggressions inflicted by predators, and an internal or gut-defense system that deters them from over-ingesting toxins. We conducted a study with cattle to investigate the relation between skin- and gut-defense systems and...

  7. Self-grooming by mares and foals of the Welsh pony. (Equus caballus)

    | Contributor(s):: Crowell-Davis, S. L.

    Self-grooming behaviour of 15 mare-foal pairs was studied weekly for the first 24 weeks of the foal's life. Mares self-groomed at mean rates of 1.2-2.2 times/h depending on the 4-week period. Foals self-groomed more often, with a peak rate of 12.3 times/h occurring during weeks 5-8 and a...

  8. Teat-seeking behaviour in newborn lambs. I. Evidence for the influence of maternal skin temperature. II. Evidence for the influence of the dam's surface textures and degree of surface yield

    | Contributor(s):: Billing, A. E., Vince, M. A.

    In an investigation of whether newborn lambs could use surface temperatures as a cue for locating the teat for the first time, the indices for the response to artifical surfaces were the duration of nosing, number of times the mouth opened and number of licks on the surface. Newborn, unsuckled...

  9. The ear skin temperature as an indicator of the thermal comfort of pigs

    | Contributor(s):: Andersen, H. M. L., Jorgensen, E., Dybkjaer, L., Jorgensen, B.

    The aim of the study was to investigate the relationship between the ear skin temperature and the behaviour of pigs. Fifty-four pigs weighing 75+or-5 kg were used in three replications (18 pigs per replication) and housed in pens (six pigs per pen) in a controlled climate facility. The room...

  10. Application of the Welfare QualityReg. protocol at pig slaughterhouses

    | Contributor(s):: Dalmau, A., Temple, D., Rodriguez, P., Llonch, P., Velarde, A.

    The objective of the present study was to assess the sensitivity and feasibility of the Welfare QualityReg. (WQ) protocol for finishing pigs in 10 Spanish slaughterhouses. Sensitivity refers to the ability of the WQ assessment system to discriminate between slaughter conditions whilst feasibility...

  11. Can environmental variables replace some animal-based parameters in welfare assessment of dairy cows?

    | Contributor(s):: Mulleder, C., Troxler, J., Laaha, G., Waiblinger, S.

    Animal-related parameters best fulfil the requirements of a valid welfare assessment, but often they are less feasible than other parameters. Therefore, this paper examines whether animal-based parameters are connected with each other and with environmental factors in order to find out if some...

  12. Effects of fattening boars in mixed or single sex groups and split marketing on pig welfare

    | Contributor(s):: Boyle, L. A., Bjorklund, L.

    Our aim was to evaluate the effects of single or mixed sex fattening of boars and split marketing (SM) on pig welfare. Female (n=10), male (n=10) and mixed sex (n=10) groups were fattened to 105 kg. Two focal pigs per pen were selected for continuous behaviour observations and skin lesion...

  13. Evaluation of parameters for monitoring welfare during transport and lairage at the abattoir in pigs

    | Contributor(s):: Fabrega, E., Coma, J., Tibau, J., Manteca, X., Velarde, A.

    New transport legislation and society demands may increase the need for a 'fast' method to assess animal welfare at the abattoir. The objective of this study was to identify valid and feasible parameters which could be easily assessed at slaughterline in pigs. Eight transports (4 'far' and 4...

  14. How to deal with complex data of skin lesions in weaner pigs

    | Contributor(s):: Baumgartner, J.

    Skin lesions of pigs can be used as an indicator of their ability to adapt to the social and physical environment. A total of 315 weaner pigs were assigned to one of three treatments: groups of nine piglets from one litter (9 s), mixed groups of nine piglets from three litters (9 m) or mixed...

  15. Peripartal behaviour and teat lesions of sows in farrowing crates and in a loose-housing system

    | Contributor(s):: Verhovsek, D., Troxler, J., Baumgartner, J.

    Housing of farrowing and lactating sows in farrowing crates can cause a number of welfare problems. Recently, alternative farrowing pens have been developed which allow the sow to turn around and move freely. In this experiment a conventional farrowing crate (C; 5.0 m2; the sow is crated...

  16. Preliminary assessment of finishing pig welfare using animal-based measurements

    | Contributor(s):: Whay, H. R., Leeb, C., Main, D. C. J., Green, L. E., Webster, A. J. F.

    A preliminary investigation was undertaken to evaluate a series of animal-based welfare measures for the assessment of finishing pigs in units that were members of the RSPCA Freedom Food farm assurance scheme. A total of 20 finishing pig units were visited in the summer of 2002 and 14 of these...

  17. Preliminary evaluation of a prototype welfare monitoring system for sows and piglets (Welfare QualityReg. project)

    | Contributor(s):: Scott, K., Binnendijk, G. P., Edwards, S. A., Guy, J. H., Kiezebrink, M. C., Vermeer, H. M.

    The Welfare QualityReg. project aims to develop a European on-farm welfare assessment standard for pigs, amongst other species. A prototype monitoring system was developed for sows and piglets using predominantly animal-based measures of behaviour, health and physiology to assess welfare. The...

  18. Reducing post-mixing aggression and skin lesions in weaned pigs by application of a synthetic maternal pheromone

    | Contributor(s):: Guy, J. H., Burns, S. E., Barker, J. M., Edwards, S. A.

    In commercial pig production, piglets are often mixed after weaning which can result in severe aggression and lead to body damage, disruption of feeding behaviour and reduced growth. This experiment investigated whether application of a synthetic maternal pheromone to groups of weaned pigs in...

  19. Relation between parity and feed intake, fear of humans and social behaviour in non-lactating sows group-housed under various on-farm conditions

    | Contributor(s):: Kongsted, A. G., Hermansen, J. E., Kristensen, T.

    The number of group-housed, non-lactating sows is increasing rapidly in Europe. However, systematic information of the between-sow variation in animal welfare related factors under various on-farm conditions is lacking. Indicators of feed intake, fear of humans and social behaviour in...

  20. Relationships between pathology and pain severities: a review

    | Contributor(s):: Gregory, N. G.

    The relationships between pathology severity and pain severity are reviewed using the literature available for humans. The aim is to help veterinary radiologists, physicians and pathologists recognise the disorders in which severity of a lesion is likely to be related to the severity of pain or...
