  1. Chewable materials before weaning reduce tail biting in growing pigs

    Contributor(s):: Telkanranta, H., Swan, K., Hirvonen, H., Valros, A.

    Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...

  2. Docking the value of pigmeat? Prevalence and financial implications of welfare lesions in Irish slaughter pigs

    Contributor(s):: Harley, S., Boyle, L. A., O'Connell, N. E., More, S. J., Teixeira, D. L., Hanlon, A.

    Expansion of the meat inspection process to incorporate animal-based welfare measurements could contribute towards significant improvements in pig ( Sus scrofa domesticus) welfare and farm profitability. This study aimed to determine the prevalence of different welfare-related lesions on the...

  3. Does nest size matter to laying hens?

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

    Laying hens in loose housing systems have access to group-nests which provide space for several hens at a time to lay their eggs. They are thus rather large and the trend in the industry is to further increase the size of these nests. Though practicality is important for the producer, group-nests...

  4. Effect of gestation management system on gilt and piglet performance

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

    Individual gestation housing of pregnant sows in stalls from four weeks after mating is banned in the EU. Two experiments were conducted to study the effect of two gestation management and housing systems (STALL: gilts housed in stalls and PEN: gilts loose-housed in pens with increased feed...

  5. Effects of chronic intake of starch-, glucose- and fructose-containing diets on eating behaviour in adult minipigs

    Contributor(s):: Ochoa, M., Malbert, C. H., Lalles, J. P., Bobillier, E., Val-Laillet, D.

    Introduction: The aim of this study was to assess whether chronic intake of isocaloric high-fat diets differing partly in the source of carbohydrates (starch, glucose or fructose) and fed at the same level of intake impacts eating behaviour in the adult Yucatan minipig. Methods: Adult minipigs...

  6. Effects of genetic selection for residual feed intake on behavioral reactivity of castrated male pigs to novel stimuli tests

    Contributor(s):: Colpoys, J. D., Abell, C. E., Young, J. M., Keating, A. F., Gabler, N. K., Millman, S. T., Siegford, J. M., Johnson, A. K.

    Increasing feed efficiency in swine is important for increasing sustainable food production and profitability for producers; therefore, this is often selected for at breeding. Residual feed intake (RFI) can be used for the genetic selection of pigs for feed efficiency. In our selection project,...

  7. Effects of stocking rate on measures of efficacy and welfare during carbon dioxide gas euthanasia of young pigs

    Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.

    The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs ( Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned...

  8. Group suckling cohesion as a prelude to the formation of teat order in piglets

    Contributor(s):: Skok, J., Skorjanc, D.

    During the lactation period, piglets experience intense social interactions with their littermates until they establish a reliable teat order on the mother's udder. Here, we examined group suckling cohesion in piglet littermates, an order mechanism that refer to the maintenance of significantly...

  9. Lack of mirror use by pigs to locate food

    Contributor(s):: Gieling, E. T., Mijdam, E., Staay, F. J. van der, Nordquist, R. E.

    Many mammalian species, as well as birds, are able to use a mirror either in the context of self-recognition, or instrumentally for discovering and manipulating objects that cannot be perceived directly. A noteworthy study by Broom et al. (2009) investigated the ability of pigs ( Sus scrofa) to...

  10. Nest building and posture changes and activity budget of gilts housed in pens and crates

    Contributor(s):: Andersen, I. L., Vasdal, G., Pedersen, L. J.

    The aim of the present work was to study nest building, posture changes and the overall activity budget of gilts in pens vs. crates. Twenty-three HB gilts (high piglet survival day 5) and 21 LB gilts (low piglet survival day 5) were video recorded from day 110 in pregnancy to four days after...

  11. Scientists and Dutch pig farmers in dialogue about tail biting: unravelling the mechanism of multi-stakeholder learning

    Contributor(s):: Benard, M., Schuitmaker, T. J., Buning, T. de C.

    Pig farmers and scientists appear to have different perspectives and underlying framing on animal welfare issues as tail biting and natural behaviour of pigs. Literature proposes a joint learning process in which a shared vision is developed. Using two different settings, a symposium and...

  12. Socialising piglets in lactation positively affects their post-weaning behaviour

    Contributor(s):: Morgan, T., Pluske, J., Miller, D., Collins, T., Barnes, A. L., Wemelsfelder, F., Fleming, P. A.

    Although commercial farrowing sheds keep individual litters separated, previous studies have suggested that housing systems that allow socialisation of piglets pre-weaning can reduce aggression after weaning. This study tested whether pigs socialised with non-litter mates pre-weaning would show...

  13. Tail biting behaviour and tail damage in pigs and the relationship with general behaviour: predicting the inevitable?

    Contributor(s):: Ursinus, W. W., Reenen, C. G. van, Kemp, B., Bolhuis, J. E.

    Tail biting behaviour in pigs is a common problem in conventional housing systems. Our study examined the consistency over time in tail biting and tail damage and it explored the predictive value of general behaviours observed in individual pigs and in pens as a whole. Pigs ( n=480), reared in...

  14. The effect of ketoprofen on post-partum behaviour in sows

    Contributor(s):: Viitasaari, E., Raekallio, M., Heinonen, M., Valros, A., Peltoniemi, O., Hanninen, L.

    A randomized, double-blinded, placebo controlled trial was conducted in order to estimate pain-related behavioural changes of sows in early lactation. Ketoprofen (KET) was used (3 mg/kg BW) intramuscularly for three consecutive days post-partum (p.p.) on 19 sows. Nineteen sows were used as a...

  15. BIOETHICS SYMPOSIUM II: current factors influencing perceptions of animals and their welfare

    Contributor(s):: McKendree, M. G. S., Croney, C. C., Widmar, N. J. O.

    To address escalating concerns about livestock animal care and welfare it is necessary to better understand the factors that may predispose people to develop such concerns. It has been hypothesized that experiences with, beliefs about, and emotional connections to animals may influence level of...
