The effect of demonstrator social rank on the attentiveness and motivation of pigs to positively interact with their human caretakers
| Contributor(s):: Luna, D., Gonzalez, C., Byrd, C. J., Palomo, R., Huenul, E., Figueroa, J.
In this study, we addressed the social attentiveness, as well as the phenomenon of social facilitation and inhibition in the context of a positive human–pig relationship. Specifically, we investigated whether the social rank of an experienced pig (termed “demonstrator”) has an...

Interaction between sows’ aggressiveness post mixing and skin lesions recorded several weeks later
| Contributor(s):: Tönepöhl, Björn, Appel, Anne K., Voß, Barbara, König von Borstel, Uta, Gauly, Matthias
Group housing of pigs leads inevitably to more or less serious agonistic interactions during the establishment of the social rank order of the group. In order to reduce the number of severe agonistic interactions and thus the negative effects on well-being and performance, the use of genetic...

Immunocastration with Improvac™ reduces aggressive and sexual behaviours in male pigs
| Contributor(s):: Brewster, Veronica, Nevel, Amanda
Surgical castration of male pigs is a common practice to reduce the risk of boar taint, an accumulation of pheromones in the muscles of pigs giving an undesirable odour to the pork of entire boars. Castration is not widely practiced in the UK for welfare reasons and indeed, assurance schemes...

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...

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...

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...

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...

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...

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...

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...

Maximum permissible load for Yonaguni ponies (Japanese landrace horses) trotting over a short, straight course
| Contributor(s):: Matsuura, A., Mano, H., Irimajiri, M., Hodate, K.
This study aimed to determine the load-bearing capacity of trotting Yonaguni ponies using gait analysis. The Yonaguni pony is one of the Japanese landrace horses, and has normal gait characteristics when trotting. As a breed they are small in stature and hence susceptible to the effect of the...

Effects of stocking rate on measures of efficacy and welfare during argon gas euthanasia of weaned 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 euthanasia of weaned pigs ( Sus scrofa domesticus) with argon gas. Two hundred and thirty-three weaned pigs designated for euthanasia at a commercial production farm...

Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs
| Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.
Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

Social support does not require attachment: any conspecific tranquilizes isolated guinea-pig pups
| Contributor(s):: Tokumaru, R. S., Ades, C., Monticelli, P. F.
Guinea pig pups produce typical distress whistles when isolated. Whistles' frequency is decreased or abolished when they contact with the mother and, to a lesser degree, a sibling or even an unfamiliar female, is regained. Those non-aggressive companions were considered social support...

Effect of increasing amounts of straw on pigs' explorative behaviour
| Contributor(s):: Jensen, M. B., Herskin, M. S., Forkman, B., Pedersen, L. J.
According to European legislation, pigs must have permanent access to sufficient quantity of material to enable manipulation activities. However, few studies have quantified how much straw is needed to fulfil the requirements of growing pigs. We investigated the effect of increasing amount of...

Hunger in pregnant sows: effects of a fibrous diet and free access to straw
| Contributor(s):: Jensen, M. B., Pedersen, L. J., Theil, P. K., Knudsen, K. E. B.
Fibrous diets and the provision of straw have been suggested to reduce feeding motivation in pregnant sows. The present experiment investigated the separate and interactive effects of a fibrous diet and ad libitum access to straw on feeding motivation, oral behaviour and plasma levels of...

Piglets call for maternal attention: vocal behaviour in Sus scrofa domesticus is modulated by mother's proximity
| Contributor(s):: Iacobucci, P., Colonnello, V., D'Antuono, L., Cloutier, S., Newberry, R. C.
Plasticity in the production of "separation distress" vocalizations, and seeking of caregivers beyond mere satisfaction of immediate physiological needs, are manifestations of attachment that we investigated in the domestic pig ( Sus scrofa domesticus). Female piglets from eight litters...
