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...
Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans
| Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.
Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...
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...
Early human handling in non-weaned piglets: effects on behaviour and body weight
| Contributor(s):: Oliveira, D. de, Costa, M. J. R. P. da, Zupan, M., Rehn, T., Keeling, L. J.
Early handling of animals including tactile stimulation (TS) has been shown to have beneficial effects on the physical and psychological development of species where considerable maternal interaction, e.g. in the form of licking, already occurs. But little is known about the magnitude of these...
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 growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter
| Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.
There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...
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...
Persistency of the piglet's reactivity to the handler following a previous positive or negative experience
| Contributor(s):: Brajon, S., Laforest, J. P., Bergeron, R., Tallet, C., Hotzel, M. J., Devillers, N.
A central question in the stockman-animal relationship is how animals perceive humans depending on previous interactions with them. This study aimed at measuring the influence of a previous experience with humans on subsequent reactivity to humans of weaned piglets. Treatments differing in type...
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...
Facilitating 'learning from mom how to eat like a pig' to improve welfare of piglets around weaning
| Contributor(s):: Oostindjer, M., Kemp, B., Brand, H. van den, Bolhuis, J. E.
Piglets in commercial husbandry are weaned abruptly and at a rather young age. Many weanling piglets are poorly adapted to ingest solid food, often resulting in a period of underfeeding. The underfeeding generally leads to a poor growth, diarrhoea occurrence and the development of damaging...
How much is enough? The amount of straw necessary to satisfy pigs' need to perform exploratory behaviour
| Contributor(s):: Pedersen, L. J., Herskin, M. S., Forkman, B., Halekoh, U., Kristensen, K. M., Jensen, M. B.
Since 10 years, EU-legislation states that 'pigs must have permanent access to sufficient quantity of material to enable proper investigation and manipulation activities'. While much research has focused on which materials 'enable proper investigation and manipulation activities',...
Same pig, different conclusions: stakeholders differ in qualitative behaviour assessment
| Contributor(s):: Duijvesteijn, N., Benard, M., Reimert, I., Camerlink, I.
Animal welfare in pig production is frequently a topic of debate and is sensitive in nature. This debate is partly due to differences in values, forms, convictions, interests and knowledge among the stakeholders that constitute differences among their frames of reference with respect to pigs and...
A combination of behavioral and physiological indicators for assessing pig welfare on the farm
| Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.
The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...
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...
Hoop housing for feeder pigs offers a welfare-friendly environment compared to a nonbedded confinement system
| Contributor(s):: Lay, D. C., Jr., Haussmann, M. F., Daniels, M. J.
A nonbedded confinement system (NBCS) was compared with hoop structures (Hoop) for housing of feeder pigs. The Hoop is an inexpensive alternative to the total confinement system. Open-ended Quonsets shaped like a half cylinder lying on its flat side, the Hoop use bedding to keep the pigs dry and...
Increasing the frequency of co-mingling piglets during the lactation period alters the development of social behavior before and after weaning
| Contributor(s):: Kanaan, V. T., Lay, D. C., Jr., Richert, B. T., Pajor, E. A.
The purpose of this study was to determine how increasing the frequency of co-mingling affected piglets' behavior development before and after weaning. Co-mingling once (CM1), piglets interacted with 1 unfamiliar litter Days 10-18 after birth; co-mingling twice (CM2), piglets interacted with 1...
Scientists and Dutch pig farmers in dialogue about tail biting: unravelling the mechanism of multi-stakeholder learning
| Contributor(s):: Benard, M., Schuitmaker, T. J., Buning, T. de C.
Pig farmers and scientists appear to have different perspectives and underlying framing on animal welfare issues as tail biting and natural behaviour of pigs. Literature proposes a joint learning process in which a shared vision is developed. Using two different settings, a symposium and...
