  1. Achieving optimum performance in a loose-housed farrowing system for sows: the effects of space and temperature

    Contributor(s):: Baxter, E. M., Adeleye, O. O., Jack, M. C., Farish, M., Ison, S. H., Edwards, S. A.

    Piglet survival relies on interactive influences of the sow, her piglets and their environment. There are a number of design challenges in a loose-housed farrowing and lactation system to optimise this dynamic, including achieving farrowing in the desired location (i.e. a protected nest area) and...

  2. Diurnal rhythms, locations and behavioural sequences associated with eliminative behaviours in fattening pigs

    Contributor(s):: Guo, YuGuang, Lian, XinMing, Yan, PeiShi

    Understanding eliminative behaviours in pigs is very important to maintain individual and pen cleanliness. In this experiment, twenty fattening pigs were housed in four concrete floor pens with a floor space of 3.25 m 2 per pig and free accessibility of outdoor runs. We studied the diurnal...

  3. 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...

  4. Network characteristics and development of social structure of agonistic behaviour in pigs across three repeated rehousing and mixing events

    Contributor(s):: Buttner, K., Scheffler, K., Czycholl, I., Krieter, J.

    In commercial pig production, the mixing of unacquainted pigs is a standard procedure which leads to agonistic interactions with a wide range of individual pig behaviour. A reduction in these agonistic interactions positively affects animal health, welfare aspects and production parameters. With...

  5. The backtest in pigs revisited - an analysis of intra-situational behaviour

    Contributor(s):: Zebunke, M., Repsilber, D., Nurnberg, G., Wittenburg, D., Puppe, B.

    The occurrence of different behavioural phenotypes in animals (regarding temperament and personality) has increasingly attracted the attention of scientists dealing with farm animal breeding, management and welfare. As part of the adaptation repertoire, coping behaviour describes how animals deal...

  6. Living with transgenic animals

    Contributor(s):: Clark, J. L.

  7. Analysis of the phenotypic link between behavioural traits at mixing and increased long-term social stability in group-housed pigs

    Contributor(s):: Desire, S., Turner, S. P., D'Eath, R. B., Doeschl-Wilson, A. B., Lewis, C. R. G., Roehe, R.

    Mixing of growing pigs results in aggressive contests between group members. As aggression serves to establish dominance relationships, it is possible that increased initial aggression may facilitate the formation of social hierarchies. The objective of the study was to investigate whether there...

  8. Application of the Welfare Quality animal welfare assessment system in Finnish pig production, Part I: Identification of principal components

    Contributor(s):: Munsterhjelm, C., Heinonen, M., Valros, A.

    The Welfare Quality (WQ) on-farm welfare assessment protocols for fattening pigs (n=95 farms) and sows, as well as suckling piglets (n=103 farms), were applied on Finnish farms. In order to identify distinct types of welfare problems (WPTs) Principal Component Analysis (PCA) was applied to the...

  9. Application of the Welfare Quality animal welfare assessment system in Finnish pig production, Part II: Associations between animal-based and environmental measures of welfare

    Contributor(s):: Munsterhjelm, C., Heinonen, M., Valros, A.

    This study aimed to establish associations between the environment and animal-based measures of welfare collected on 158 Finnish farms according to the Welfare Quality systems for pigs. The data consisted of 95 welfare assessments in fattening pigs and 103 in sows, including suckling piglets....

  10. Comparison of the behaviour of piglets raised in an artificial rearing system or reared by the sow

    Contributor(s):: Rzezniczek, M., Gygax, L., Wechsler, B., Weber, R.

    Over the last 15 years, rising sow fertility has led to a considerable increase in litter size. As a consequence, the number of live born piglets may outnumber the number of functional teats, and surplus piglets are removed from the sow at the age of 3-6 days and fed with artificial milk. The...

  11. Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality

    Contributor(s):: Muns, R., Manteca, X., Gasa, J.

    An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

  12. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  13. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  14. Killing the enviropigs

    Contributor(s):: Clark, J. L.

    In spring 2012, after losing the main source of funding for its Enviropig project, the University of Guelph killed its last remaining Enviropigs. Or, as a university spokesperson put it, the pigs were "humanely euthanized." Through an engagement with this particular case, I examine the ethical...

  15. Moral values and attitudes toward Dutch sow husbandry

    Full-text: Available

    | Contributor(s):: Bergstra, T. J., Gremmen, B., Stassen, E. N.

    Attitudes toward sow husbandry differ between citizens and conventional pig farmers. Research showed that moral values could only predict the judgment of people in case of culling healthy animals in the course of a disease epidemic to a certain extent. Therefore, we hypothesized that attitudes...

  16. Predicting time spent on different behavioural activities from physicochemical properties of fibrous diets in finishing pigs

    | Contributor(s):: Bakare, A. G., Ndou, S. P., Madzimure, J., Chimonyo, M.

    The objective of the present study was to predict time spent on different behavioural activities by finishing pigs, using physicochemical measurements of fibrous feed. Eighty four Large White * Landrace barrows with 80.54.7 kg body weight (BW) at the beginning of the experiment were used. Feed...

  17. Rooting area and drinker affect dunging behaviour of organic pigs

    | Contributor(s):: Vermeer, H. M., Altena, H., Vereijken, P. F. G., Bracke, M. B. M.

    Hygiene is a common problem on outdoor runs of growing organic pigs. Manure and urine are mainly excreted outdoors and tend to spread all over the run. Reducing the soiled surface area may be beneficial to animal welfare, hygiene, ammonia emissions and labour, not only in organic but also in...

  18. Strategic use of straw increases nest building in loose housed farrowing sows

    | Contributor(s):: Westin, R., Hultgren, J., Algers, B.

    In spite of domestication, sows are still genetically programmed to perform nesting behaviour close to farrowing. In order to facilitate nest building, a method for a strategic use of large quantities of straw has been developed by Swedish piglet producing farmers. The objectives of the present...

  19. The effect of overgrown claws on behaviour and claw abnormalities of sows in farrowing crates

    | Contributor(s):: Diaz, J. A. C., Stienezen, I. M. J., Leonard, F. C., Boyle, L. A.

    The objective of this study was to evaluate the effect of overgrowth of the weight bearing claws on the behaviour of sows in farrowing crates. The study used 24 multiparous lactating sows, 13 with overgrown (OG) rear claws and 11 controls. Sows were video recorded continuously from approximately...

  20. Willingness of Dutch broiler and pig farmers to convert to production systems with improved welfare

    | Contributor(s):: Gocsik, E., Lans, I. A. van der, Lansink, A. G. J. M. O., Saatkamp, H. W.

    The present study investigated 15 broiler and 13 fattening pig farmers' willingness-to-convert to alternative production systems with higher animal welfare standards compared to conventional production systems in The Netherlands, and explored the main barriers to the adoption of these alternative...
