| Contributor(s):: Yadana, S., Cheun-Arom, T., Li, H., Hagan, E., Mendelsohn, E., Latinne, A., Martinez, S., Putcharoen, O., Homvijitkul, J., Sathaporntheera, O., Rattanapreeda, N., Chartpituck, P., Yamsakul, S., Sutham, K., Komolsiri, S., Pornphatthananikhom, S., Petcharat, S., Ampoot, W., Francisco, L., Hemachudha, T., Daszak, P., Olival, K. J., Wacharapluesadee, S.
BACKGROUND: Interactions between humans and animals are the key elements of zoonotic spillover leading to zoonotic disease emergence. Research to understand the high-risk behaviors associated with disease transmission at the human-animal interface is limited, and few consider regional and local...
Sow behavior during introduction to a large dynamic group is influenced by familiarity and method
| Contributor(s):: Kranz, Victoria A., Horback, Kristina M., Parsons, Thomas D., Pierdon, Meghann K.
Sows in an extensive setting maintain small, stable matrilineal social groups comprised of familiar, and often genetically related, conspecifics. Providing conditions in an intensive farm setting which allow similar social groups could reduce aggression by allowing familiar sows to benefit from...
Virulence Genes, Shiga Toxin Subtypes, Serogroups, and Clonal Relationship of Shiga Toxin-Producing Escherichia Coli Strains Isolated from Livestock and Companion Animals
| Contributor(s):: Nicolás Galarce, Beatriz Escobar, Fernando Sánchez, Esteban Paredes-Osses, Raúl Alegría-Morán, Consuelo Borie
Shiga toxin-producing Escherichia coli (STEC) is a zoonotic pathogen that causes severe illness in humans and is an important cause of foodborne disease. In Chile, there is limited information on the virulence characteristics of this pathogen in livestock, and none in companion...

Integrated value-chain and risk assessment of Pig-Related Zoonoses in Ghana
| Contributor(s):: Ayodele O. Majekodunmi, Henry Ofosu Addo, Husein Bagulo, Langbong Bimi
The marked increase in the pig-trade in Ghana has raised concerns about increased transmission of related zoonotic diseases. A study on pig-related zoonoses along the pork valuechain was conducted in Greater Accra and Upper East Regions of Ghana. Results showed significant taenia (60%) and...
Adenoviral Gene Transfer of Gremlin Modulates Vascular Endothelial Growth Factor-A-Induced Angiogenesis in Porcine Myocardium

Identification of specific call types produced by pre-weaning gilts in response to isolation

Prenatal stress and ketamine affect the behavioral and physiological responsiveness of early adolescent pigs to a novel arena and social confrontation test
| Contributor(s):: Backus, Brittany L., Bryer, Pamela J., Sutherland, Mhairi A.
Elevated maternal glucocorticoid concentrations during gestation can affect how the offspring respond, both behaviorally and physiologically, to a challenge later in life. The objectives of this study were to first, determine if elevated maternal glucocorticoid concentrations during late...
The pig's nose and its role in dominance relationships and harmful behaviour
| Contributor(s):: Camerlink, I., Turner, S. P.
Affiliative behaviour may have an essential role in many behavioural processes. Gently nosing between group members occurs in almost all social behavioural processes of pigs (Sus scrofa), but the reasons for its performance are unclear. We examined whether nosing between pigs was related to...
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...
Does the presence of a human affect the preference of enrichment items in young, isolated pigs?
| Contributor(s):: DeBoer, Shelly P., Garner, Joseph P., Lay, Donald C., Eicher, Susan D., Lucas, Jeffrey R., Marchant-Forde, Jeremy N.
Pigs may be housed individually in both production and research settings. Gregarious by nature, pigs kept in isolation may show behavioural and physiological signs of stress. In this study we investigated the preference of individually housed pigs, for social and non-social enrichments. Three...
Chewable materials before weaning reduce tail biting in growing pigs
| Contributor(s):: Telkänranta, Helena, Swan, Kirsi, Hirvonen, Heikki, Valros, Anna
Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...
Relationship between growth rate and oral manipulation, social nosing, and aggression in finishing pigs
| Contributor(s):: Camerlink, Irene, Bijma, Piter, Kemp, Bas, Bolhuis, J. Elizabeth
Pigs may affect each other's health, welfare and productivity through their behaviour. The effect of a pig on the growth rate of its pen mates is partly heritable and is referred to as its social genetic effect. Social genetic effects, also known as indirect genetic effects, have been found in a...
Effect of genetic homogeneity on behavioural variability in an object recognition test in cloned Göttingen minipigs
| Contributor(s):: Søndergaard, Lene Vammen, Herskin, Mette S., Ladewig, Jan, Holm, Ida Elisabeth, Dagnæs-Hansen, Frederik
The number of animals used in research should be limited as much as possible. Among cloned animals, genetic variation is minimal and to the extent that behaviour is genetically determined inter-individual variability is expected to be higher among naturally bred animals. However, the cloning...
The effect of domestication and ontogeny in swine cognition (Sus scrofa scrofa and S. s. domestica)
| Contributor(s):: Albiach-Serrano, Anna, Bräuer, Juliane, Cacchione, Trix, Zickert, Nele, Amici, Federica
Domesticated animals show physical, behavioural and cognitive differences from their closest wild relatives. This may have resulted from the former's long and continued selection by humans throughout history, but in some cases it could just reflect developmental differences between wild and...
