  1. Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later

    | Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias

    Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...

    The objective of the present study is to assess the variability of the measures used in the welfare quality (WQ) protocol for pigs among slaughterhouses in five different countries and to propose alarm and critical thresholds for the calculation of scores for future development of an animal...

  3. Influence of teeth resection on the skin temperature and acute phase response in newborn piglets

    | Contributor(s):: Llamas Moya, S., Boyle, L. A., Lynch, P. B., Arkins, S.

  4. Effect of a synthetic plate in the lying area on lying behaviour, degree of fouling and skin lesions at the leg joints of finishing pigs

    | Contributor(s):: Savary, P., Gygax, L., Wechsler, B., Hauser, R.

    Flooring type may have a major influence on thermoregulatory behaviour in finishing pigs, as well as on the occurrence of skin lesions at their leg joints and pen fouling. In this study, we compared the lying behaviour, pen fouling and the occurrence of leg lesions in finishing pigs kept in...

  5. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    | Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  6. 'Subordination style' in pigs? The response of pregnant sows to mixing stress affects their offspring's behaviour and stress reactivity

    | Contributor(s):: Ison, S. H., D'Eath, R. B., Robson, S. K., Baxter, E. M., Ormandy, E., Douglas, A. J., Russell, J. A., Lawrence, A. B., Jarvis, S.

    In various mammals stress during gestation can result in long term effects on the behaviour and physiology of the offspring. The aims of this study were (i) to characterise individual variation among primiparous sows (gilts) in their behavioural and physiological response to a commercially...

  7. Assessment of animal welfare in 80 dairy cow herds in cubicle housing # animal health and other animal-related parameters

    | Contributor(s):: Rouha-Mulleder, C., Palme, R., Waiblinger, S.

    Introduction: With growing concerns about farm animal welfare (e.g. by consumers; WILDNER, 1998), knowledge about the actual situation with regard to animal welfare on farms is important. Valid assessment of animal welfare requires the use of animal-based parameters, while environmental...

  8. 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...

  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. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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...

  17. 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...

  18. Selection against aggressiveness in pigs at re-grouping: practical application and implications for long-term behavioural patterns

    | Contributor(s):: Turner, S. P., D'Eath, R. B., Roehe, R., Lawrence, A. B.

    The routine mixing of pigs causes aggression that cannot be greatly reduced by low-cost environmental changes. The variability and heritability of aggressiveness are discussed and both appear adequate to make selection against aggressiveness worthwhile in grower-stage pigs. Selection would...

  19. Social behaviour and injuries of horned cows in loose housing systems

    | Contributor(s):: Menke, C., Waiblinger, S., Folsch, D. W., Wiepkema, P. R.

    The relationship between social behaviour and skin injuries (caused by horns) of loose housed horned cows was investigated on 35 dairy farms (mean herd-size, 34.54, range, 8-80). While the frequencies of 2 agonistic behaviour elements (push and chase away) were positively correlated with the...
