    The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...

  8. A multidisciplinary approach to assess the welfare of weaned pigs during transport at three space allowances

    | Contributor(s):: Sutherland, M. A., Bryer, P. J., Davis, B. L., McGlone, J. J.

    Transport can be a stressful experience for pigs, especially in pigs simultaneously experiencing weaning stress. The objective of this study was to use a multidisciplinary approach to assess the welfare of weaned pigs during transport at 3 space allowances. A commercial semitrailer, fitted with...

  9. Aggressive behavior in two different group-housing systems for pregnant sows

    | Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.

    The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...

  10. Can ambient sound reduce distress in piglets during weaning and restraint?

    | Contributor(s):: Cloutier, S., Weary, D. M., Fraser, D.

    This study monitored the vocal responses of piglets, as indicators of well-being, to evaluate the effect of various sounds played during 2 simulations of stressful farm procedures: (a) the 5 min the animals were held as if for castration and (b) the first 20 h after weaning. The sound treatments...

  11. Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene

    | Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.

    A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...

  12. Do domestic pigs in controlled environments contrafreeload?

    | Contributor(s):: Young, R. J., Lawrence, A. B.

    Many experiments report that animals will work (lever press) for food in the presence of freely available identical food. This phenomenon has attracted the attention of applied ethologists because it seems to prove that animals have a need to express appetitive behaviour. If this is the case,...

  13. Feeder use patterns in group-housed pregnant sows fed with an unprotected electronic sow feeder (Fitmix)

    | Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Baucells, M. D., Gasa, J., Manteca, X.

    Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity - housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix feeder...

  14. Hoop housing for feeder pigs offers a welfare-friendly environment compared to a nonbedded confinement system

    | Contributor(s):: Lay, D. C., Jr., Haussmann, M. F., Daniels, M. J.

    A nonbedded confinement system (NBCS) was compared with hoop structures (Hoop) for housing of feeder pigs. The Hoop is an inexpensive alternative to the total confinement system. Open-ended Quonsets shaped like a half cylinder lying on its flat side, the Hoop use bedding to keep the pigs dry and...

  15. If you knew what was good for you! The value of environmental enrichments with known welfare benefits is not demonstrated by sows using operant techniques

    | Contributor(s):: Elmore, M. R. P., Garner, J. P., Johnson, A. K., Kirkden, R. D., Richert, B. T., Pajor, E. A.

    This study assessed the motivation of gestating sows housed in standard, barren gestation stalls (used for breeding/implantation and/or gestation) for access to environmental enrichment. Enrichment consisted of a cotton rope or rubber mat in comparison to positive (additional food when fed at...

  16. Increasing the frequency of co-mingling piglets during the lactation period alters the development of social behavior before and after weaning
