    Objectives We aimed to determine the frequency of pH1N1 transmission between humans and swine on backyard farms in Tumbes, Peru. Design Two‐year serial cross‐sectional study comprising four sampling periods: March 2009 (pre‐pandemic), October 2009 (peak of the pandemic in Peru), April...

  2. Test-retest reliability of the Welfare Quality animal welfare assessment protocol for growing pigs

    | Contributor(s):: Czycholl, I., Kniese, C., Buttner, K., Beilage, E. G., Schrader, L., Krieter, J.

    The aim of this study was to assess the feasibility and test-retest reliability of the Welfare Quality Animal Welfare Assessment Protocol for Growing Pigs. Twenty-three German pig farms were visited repeatedly by the same trained observers; each farm being visited six times during two fattening...

  3. A Comparison of Three Animal Welfare Assessment Programs on Canadian Swine Farms

    | Contributor(s):: Ashley Nicole Roberts

    Standard measures used in animal welfare assessments include animal-based measures obtained by observing animals, resource-based measures obtained by observing facilities, and management-based measures obtained by interviewing farmers and checking records. Animal welfare assessments are composed...

  4. Relationship between behavioural tests and agonistic interactions at different age levels in pigs

    | Contributor(s):: Scheffler, K., Stamer, E., Traulsen, I., Krieter, J.

    Fighting among pigs is a normal behavioural pattern to establish a stable rank order. Enhanced aggressive behaviour in pigs in groups lead to increasing stress and injuries especially in mixing situations used as a common procedure in modern pig production systems. In such systems, it is usually...

  5. Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping

    | Contributor(s):: Fu, LingLing, Li, HuiZhi, Liang, TingTing, Zhou, Bo, Chu, QingPo, Schinckel, A. P., Yang, XiaoJing, Zhao, RuQian, Li, PingHua, Huang, RuiHua

    In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...

  6. Attitudes of veterinary students in Croatia toward farm animal welfare

    | Contributor(s):: Ostovic, M., Mesic, Z., Mikus, T., Matkovic, K., Pavicic, Z.

    This survey was undertaken to assess the attitudes of Croatian veterinary students regarding farm animal welfare issues. The study included students of all undergraduate years at the only Faculty of Veterinary Medicine in Croatia. First-year students were surveyed twice, ie before and after...

  7. 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...

  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. 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...

  11. Same pig, different conclusions: stakeholders differ in qualitative behaviour assessment

    | Contributor(s):: Duijvesteijn, N., Benard, M., Reimert, I., Camerlink, I.

    Animal welfare in pig production is frequently a topic of debate and is sensitive in nature. This debate is partly due to differences in values, forms, convictions, interests and knowledge among the stakeholders that constitute differences among their frames of reference with respect to pigs and...

  12. Production costs and animal welfare for four stylized hog production systems

    | Contributor(s):: Seibert, L., Norwood, F. B.

    Nonhuman animal welfare is arguably the most contentious issue facing the hog industry. Animal advocacy groups influence the regulation of hog farms and induce some consumers to demand more humane pork products. Hog producers are understandably reluctant to improve animal well being unless the...

  13. Attitudes of Canadian pig producers toward animal welfare

    | Contributor(s):: Spooner, J. M., Schuppli, C. A., Fraser, D.

    As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of...

  14. 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...

  15. 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...

  16. Mounting behaviour in finishing pigs: stable individual differences are not due to dominance or stage of sexual development
