  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. 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...

  9. 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...

  10. 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...

  11. On-farm qualitative behaviour assessment in sheep: repeated measurements across time, and association with physical indicators of flock health and welfare

    Contributor(s):: Phythian, C. J., Michalopoulou, E., Cripps, P. J., Duncan, J. S., Wemelsfelder, F.

    Qualitative Behavioural Assessment (QBA) is a 'whole-animal' methodology that assesses the expressive qualities of animal behaviour using terms such as 'tense', 'relaxed', 'anxious', and 'content'. The reliability and validity of QBA as an indicator for on-farm welfare assessment in pigs, cattle,...

  12. Are observer ratings influenced by prescription? A comparison of Free Choice Profiling and Fixed List methods of Qualitative Behavioural Assessment

    Contributor(s):: Clarke, T., Pluske, J. R., Fleming, P. A.

    Qualitative methods of behavioural assessment use observer rating scales to score the overall demeanour or body language of animals. Establishing the reliability of such holistic approaches requires test and validation of the methods used. Here, we compare two methodologies used in Qualitative...

  13. Observations of sows and piglets housed in farrowing pens with temporary crating or farrowing crates on a commercial farm

    Contributor(s):: Chidgey, K. L., Morel, P. C. H., Stafford, K. J., Barugh, I. W.

    Alternatives to farrowing crates have been developed to improve sow welfare. These alternative farrowing systems have been designed to provide more space, allowing sows greater freedom of movement during lactation. This experiment was part of a larger study comparing sow and piglet performance...

  14. Effect of gender and halothane genotype on cognitive bias and its relationship with fear in pigs

    Contributor(s):: Carreras, R., Arroyo, L., Mainau, E., Pena, R., Bassols, A., Dalmau, A., Faucitano, L., Manteca, X., Velarde, A.

    Cognitive bias (CB) has been recently proposed as a tool to study emotions by assessing the cognitive function through behaviour observation. It is based on the premise that subjects in a negative affective state perform more negative judgements about ambiguous stimuli than subjects in positive...

  15. Long-term effects of straw blocks in pens with finishing pigs and the interaction with boar type

    Contributor(s):: Bulens, A., Beirendonck, S. van, Thielen, J. van, Buys, N., Driessen, B.

    This study verified the effect of straw blocks on the behavior and growth of finishing pigs and possible interactions with the genetic background (boar type). A total of 359 finishing pigs, which were offspring from different boar types, were housed in gender-mixed pens with slatted floors. Half...

  16. Assessing walking posture with geometric morphometrics: effects of rearing environment in pigs

    Contributor(s):: Tallet, C., Seneque, E., Megnin, C., Morisset, S., Val-Laillet, D., Meunier-Salaun, M. C., Fureix, C., Hausberger, M.

    Rearing social animals like pigs in isolation from conspecifics can have consequences on behaviour and physiology. The aim of this experiment was to determine whether rearing conditions affect body posture. We adapted a method for quantitative evaluation of posture based on geometric...

  17. 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...

  18. Neonatal piglets are able to differentiate more productive from less productive teats

    Contributor(s):: Devillers, N., Giraud, D., Farmer, C.

    A previously-validated method to induce variation in milk production between teats of the same udder that is not related to the ante-posterior location of the teat was used. In the first lactation, over half of the sows' teats (teats 1, 2, 5, 6, and 7 from 1 side of the udder, and teats 3, 4, and...

  19. Assessment of aversion and unconsciousness during exposure to carbon dioxide at high concentration in lambs

    Contributor(s):: Rodriguez, P., Dalmau, A., Manteca, X., Litvan, H., Jensen, E. W., Velarde, A.

    The most widely used stunning method in sheep is electrical. However, in lambs, this method leads to rupture of the blood vessels, provoking ecchymoses. In pigs ( Sus scrofa), the use of CO 2-stunning systems has increased in popularity due to positive effects on meat quality and animal welfare...

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

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