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...
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...
Surveillance for respiratory and diarrheal pathogens at the human-pig interface in Sarawak, Malaysia

Background The large livestock operations and dense human population of Southeast Asia are considered a hot-spot for emerging viruses. Objectives To determine if the pathogens adenovirus (ADV), coronavirus (CoV), encephalomyocarditis virus (EMCV), enterovirus (EV), influenza A-D (IAV, IBV, ICV,...
The Way Humans Behave Modulates the Emotional State of Piglets
| Contributor(s):: Sophie Brajon, Jean-Paul Laforest, Océane Schmitt, Nicholas Devillers
The emotional state can influence decision-making under ambiguity. Cognitive bias tests (CBT) proved to be a promising indicator of the affective valence of animals in a context of farm animal welfare. Although it is well-known that humans can influence the intensity of fear and reactions of...
Animal influence on water, sanitation and hygiene measures for zoonosis control at the household level: A systematic literature review
| Contributor(s):: Francisco Matilla, Yael Velleman, Wendy Harrison, Mandy Nevel
Introduction Neglected zoonotic diseases (NZDs) have a significant impact on the livelihoods of the world’s poorest populations, which often lack access to basic services. Water, sanitation and hygiene (WASH) programmes are included among the key strategies for achieving the World Health...
Welfare Problems in Cattle, Pigs, and Sheep that Persist Even Though Scientific Research Clearly Shows How to Prevent Them
out of 5 stars
| Contributor(s):: Temple Grandin
Great strides have been made to improve animal welfare. Unfortunately, there are certain problems that continue to persist. The causes of these problems range from a lack of financial accountability for losses, failure to measure them, or repeating old mistakes. Some examples of persistent...

Stakeholder attitudes toward farm animal welfare
| Contributor(s):: Heleski, C. R., Mertig, A. G., Zanella, A. J.
We developed a survey to measure attitudes toward farm animal welfare, then targeted two US groups considered highly influential in this area: veterinary college faculty members with large animal/food animal emphasis (VCF) and animal science faculty members (ANS). The survey was conducted via...

A total of 22 scientists contributed to a consensus-oriented conceptual framework for assessment of farm animal welfare, addressing priority issues in cattle, pigs, and chickens. They used the Delphi method, in which participants contributed anonymously through e-mail. The framework puts welfare...
Feeder use patterns in group-housed pregnant sows fed with an unprotected electronic sow feeder (Fitmix)
| Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Baucells, M. D., Gasa, J., Manteca, X.
Previous studies on feeder use in group-housed pregnant sows focused on dynamic groups and protected electronic sow feeders (ESF). This study observed 60 pregnant sows, 1st to 8th parity - housed from Day 29 of pregnancy to 1 week before parturition in stable groups of 20 animals, 1 Fitmix feeder...
Can ambient sound reduce distress in piglets during weaning and restraint?
| Contributor(s):: Cloutier, S., Weary, D. M., Fraser, D.
This study monitored the vocal responses of piglets, as indicators of well-being, to evaluate the effect of various sounds played during 2 simulations of stressful farm procedures: (a) the 5 min the animals were held as if for castration and (b) the first 20 h after weaning. The sound treatments...
Differences in open field behavior between heterozygous and homozygous negative gilts for the RYR(1) gene
| Contributor(s):: Fabrega, E., Diestre, A., Font, J., Carrion, D., Velarde, A., Ruiz-de-la-Torre, J. L., Manteca, X.
A test widely used to assess fear and novelty responses in domestic species is the open field. The aim of this study was to investigate the effect of RYR(1) genotype on open field behavior in growing pigs. The study subjected 15 heterozygous (Nn) and 15 RYR(1)-free (NN) gilts of 19 weeks of age...
