Dog breed differences in visual communication with humans
Contributor(s):: Konno, A., Romero, T., Inoue-Murayama, M., Saito, A., Hasegawa, T.
Domestic dogs (Canis familiaris) have developed a close relationship with humans through the process of domestication. In human-dog interactions, eye contact is a key element of relationship initiation and maintenance. Previous studies have suggested that canine ability to produce human-directed...
Positive and negative gestational handling influences placental traits and mother-offspring behavior in dairy goats
Contributor(s):: Baxter, E. M., Mulligan, J., Hall, S. A., Donbavand, J. E., Palme, R., Aldujaili, E., Zanella, A. J., Dwyer, C. M.
Dairy animals are subjected to a number of potential stressors throughout their lives, including daily interactions with humans. The quality of these interactions may have direct consequences for the animal undergoing the experience, but if such events occur during gestation it may also affect...
A prospective exploration of farm, farmer, and animal characteristics in human-animal relationships: an epidemiological survey
Contributor(s):: Roches, A. de B. des, Veissier, I., Boivin, X., Gilot-Fromont, E., Mounier, L.
Human-animal relationships are essential for dairy farming. They affect work comfort and efficiency, as well as milk production. A poor human-animal relationship can result in stress and accidents to both animals and caretakers and needs to be improved. However, many studies have demonstrated the...

Effect of pre- and post-partum sow activity on maternal behaviour and piglet weight gain 24 h after birth
Contributor(s):: Illmann, G., Chaloupkova, H., Neuhauserova, K.
Within the 24 h prior to parturition sows are active and motivated to perform nest-building behaviour. The aim of this study was to investigate: (i) whether pre-partum activity (e.g. nesting and postural changes) could predict maternal behaviour 24 h post-partum (pp) and weight gain 24 h pp, and...
Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows
Contributor(s):: Wagner, K., Seitner, D., Barth, K., Palme, R., Futschik, A., Waiblinger, S.
We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth...
Effects of prepartum housing environment on abnormal behaviour, the farrowing process, and interactions with circulating oxytocin in sows
Contributor(s):: Yun, JinHyeon, Swan, K. M., Oliviero, C., Peltoniemi, O., Valros, A.
We evaluated the effects on sows of prepartum housing environment on bar-biting (BB) behaviour prior to parturition, farrowing duration from first to tenth piglets, litter size, and circulating oxytocin (OT) concentrations during birth of the first five piglets. A total of 35 sows, approximately...
Space allowance during gestation and early maternal separation: effects on the fear response and social motivation of lambs
Contributor(s):: Averos, X., Marchewka, J., Beltran de Heredia, I., Zanella, A. J., Ruiz, R., Estevez, I.
A common prenatal stressor in lambs is early maternal separation, which may be aggravated by spatial restriction of ewes during pregnancy. They may influence lambs' development and coping abilities. The aim of this study was to determine how space allowance provided to ewes during pregnancy and...
The influence of neonatal environment on piglet play behaviour and post-weaning social and cognitive development
Contributor(s):: Martin, J. E., Ison, S. H., Baxter, E. M.
Research has shown that the domestic pig is highly playful throughout its development and that play is an important aspect of social and cognitive development. Therefore, the neonatal environment is fundamental to successful stimulation of play in neonatal pigs, which could have indirect and...
Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism
Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.
The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...
Relationships between pig welfare, productivity and farmer disposition
Contributor(s):: Jaaskelainen, T., Kauppinen, T., Vesala, K. M., Valros, A.
The aim of this study was, firstly, to investigate the connection between on-farm assessed welfare scores and production parameters for sows, and secondly, to examine how farmers perceive the connection between their disposition, animal welfare and productivity. We assessed environmental and...
Can dogs alleviate the desolation created by having fewer children? An empirical study in the Japanese context
Contributor(s):: Kawata, Y.
Over the last several decades, in Japan, the young population (YP; less than 14 years old) has decreased whereas the number of registered dogs (RDs) has increased as a result of various socioeconomic factors. The total sum of YP and RD has remained virtually constant since the early 1990s. In...

A survey of abnormal repetitive behaviors in North American river otters housed in zoos
Contributor(s):: Morabito, P., Bashaw, M. J.
Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic...
Aggressive behavior in two different group-housing systems for pregnant sows
Contributor(s):: Chapinal, N., Ruiz-de-la-Torre, J. L., Cerisuelo, A., Gasa, J., Baucells, M. D., Manteca, X.
The study housed 120 pregnant sows from Day 29 of pregnancy to 1 week before parturition either in groups of 10 with trickle feeding (TRICKLE) or in groups of 20 with an unprotected electronic sow feeding (FITMIX). The study recorded aggressive interaction on 11 nonconsecutive days. Frequency of...
