    Contributor(s):: Katie Osborn, Soren Saxmose Nielson, Matthew James Denwood, Bjorn Forkman, Hans Houe

    Despite being important to the general public, the monitoring of animal welfare is not systematic. The Danish political parties agreed in 2012 to establish national animal welfare indices for cattle and pigs, and here we assess the potential for using data from the systematic meat inspection to...

  4. Penile Injuries in Immunocastrated and Entire Male Pigs of One Fattening Farm

    Contributor(s):: Simon Reiter, Susanne Zols, Mathias Ritzmann, Volker Stefanski, Ulrike Weiler

    Penile injuries in boars have been discussed as a relevant welfare problem in pork production with entire males (EM). The incidence of penile injuries with immunocastrated boars has not been described so far. Thus, it was the aim of this study to systematically compare frequency and severity of...

  5. American Citizens' Views of an Ideal Pig Farm

    Contributor(s):: Patrycia Sato, Maria J. Hotzel, Marina A.G. von Keyserlingk

    Food animal production practices are often cited as having negative animal welfare consequences. The U.S. swine industry has not been exempt from such criticisms. Little is known, however, about how lay citizens who are not actively engaged in agricultural discussions, think about swine...

  6. Optimum Drug Combinations for the Sedation of Growing Boars Prior to Castration

    Contributor(s):: Heidi S. Lehmann, Dominique Blache, Eleanor Drynan, Pema Tshewang, David J.C. Blignaut, Gabrielle C. Musk

    Juvenile male pigs were sedated for castration. Eight five-month old boars were sedated twice (two weeks apart) with a combination of detomidine (0.1 mg/kg), midazolam (0.2 mg/kg) and either butorphanol (0.2 mg/kg) (Group MDB, n = 8) or morphine (0.2 mg/kg) (Group MDM, n = 8) intramuscularly....

  7. Pig Age and Approachability Behavior to a Human Observer

    Contributor(s):: Shawna Weimar, Anna K. Johnson, Kenneth J. Stalder, Locke A. Karriker, Thomas Fangman

    The objective of this experiment was to determine if nursery pig age affected how many pigs touched and orientated to a human, or were classified as not-orientated during a human-animal interaction test using live human observation and digital image collection methodology. A complete randomized...

  8. Management strategies in farrowing house to improve piglet pre-weaning survival and growth

    Contributor(s):: Vila, R. M., Tummaruk, P.

    Post-partum and lactation are the most complex periods in the swine production chain. Newborn pigs are highly vulnerable due to relatively low body weight at birth and physiological immaturity. Most of the management strategies performed in farrowing houses are oriented to ensure a proper level...

  9. Application of the welfare quality protocol in pig slaughterhouses of five countries

    Contributor(s):: Dalmau, A., Nande, A., Vieira-Pinto, M., Zamprogna, S., Martino, G. di, Ribas, J. C. R., Costa, M. P. da, Halinen-Elemo, K., Velarde, A.

    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...

  10. A preliminary study of the effects of individual response to challenge tests and stress induced by humans on learning performance of weaned piglets (Sus scrofa)

    Contributor(s):: Brajon, S., Laforest, J. P., Schmitt, O., Devillers, N.

    This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or...

  11. Rural and urban students' perceptions of and attitudes toward brown bears in Turkey

    Contributor(s):: Ambarli, H.

    Many studies have examined adults' perceptions of and attitudes toward large carnivores to assess human-wildlife conflict and inform conservation strategies, but there have been few studies concerning children. I studied secondary school students' perceptions of and attitudes toward brown bears...

  12. Are domestic pigs (Sus scrofa domestica) able to use complex human-given cues to find a hidden reward?

    Contributor(s):: Nawroth, C., Ebersbach, M., Borell, E. von

    Understanding human-animal interactions in livestock production systems is crucial for improving animal welfare. It is therefore of general interest to investigate how livestock animals obtain information from humans. By using an object-choice paradigm, we investigated whether domestic pigs (Sus...

  13. 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...

  14. The associations between animal-based welfare measures and the presence of indicators of food safety in finishing pigs

    Contributor(s):: Alpigiani, I., Bacci, C., Keeling, L. J., Salman, M. D., Brindani, F., Pongolini, S., Hitchens, P. L., Bonardi, S.

    Stressful housing and management practices affect animals, potentially increasing their receptiveness to pathogens. Since some pathogens do not lead to clinical signs of sickness, subclinical pigs could enter the food-chain, contaminating carcases and offal at slaughter, representing a threat to...

  15. Does group size have an impact on welfare indicators in fattening pigs?

    Contributor(s):: Meyer-Hamme, S. E. K., Lambertz, C., Gauly, M.

    Production systems for fattening pigs have been characterized over the last 2 decades by rising farm sizes coupled with increasing group sizes. These developments resulted in a serious public discussion regarding animal welfare and health in these intensive production systems. Even though large...

  16. The Theoretical Application and Comparison of the Olfactory Sensory Organs in Swine vs Canines for Accelerant and Explosives Detection

    Contributor(s):: Naomi M. Sigler

    Swine may be able to work alongside scent detection canines, or replace them completely, in the scent detection field. Miniature pigs are the focus of this study since their larger counterparts can cause damage to potential evidence and to the scene itself. Ignitable Liquid Residues (ILRs) are...
