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...

Managing large litters: Selected measures of performance in 10 intermediate nurse sows and welfare of foster piglets
Contributor(s):: Kobek-Kjeldager, Cecilie, Moustsen, Vivi A., Theil, Peter K., Pedersen, Lene J.
Selection for increased litter size has led to the use of so-called nurse sows in several European countries. A nurse sow receives new piglets after having weaned her own. Nurse sows are often made in two-steps. In the two-step strategy, new-born piglets are given to a sow 4–7 days into...
Handling and moving cull sows upon arrival at the slaughterhouse—Effects of small versus larger groups of sows
Contributor(s):: Herskin, Mette S., Christensen, Sanne W., Rousing, Tine
In modern pig production up to 50 % of the sows are slaughtered each year. So far, only few studies have focused on how sows are handled and moved within slaughterhouses. We examined effects of group size on the behaviour of sows and the ease of moving them from the entrance of a slaughterhouse...
A review of neonatal mortality in outdoor organic production and possibilities to increase piglet survival
Contributor(s):: Schild, S. Lina A., Baxter, Emma M., Pedersen, Lene J.
The current level of piglet mortality in production systems with outdoor farrowing is high and conflicts with the ethical principles of organic farming. Over the last decade, there has been a rise in scientific studies addressing the level of piglet mortality in outdoor pig production and the...
Clinical and behavioural consequences of on-farm mixing of cull sows after weaning
Contributor(s):: Herskin, Mette S., Holm, Cathrine, Thodberg, Karen
In modern pig production up to 50% of the sows are slaughtered each year. Typically, the period from the decision to cull and until a sow is slaughtered consists of a stay in an on-farm pick-up pen (hours to weeks), transport (eventually passing buying stations or similar) and lairage. However,...
Efecto de algunos factores genético-ambientales sobre el tamaño de camada al nacimiento en cerdos. I. Tamaño de la Camada Nacidos Vivos (TCNV)

Chile, según información reciente de USDA, se encuentra en el sexto lugar de los principales exportadores de carne porcina del mundo. Para responder a esta demanda, los productores de cerdos se han preocupado de mejorar sus índices productivos, entre los que se encuentra el...
Parity Influences the Demeanor of Sows in Group Housing
| Contributor(s):: Clarke, Taya, Pluske, John R., Miller, David W., Collins, Teresa, Fleming, Patricia A.
Across the globe, producers are moving from individual housing to group housing for sows during gestation. Producers typically group sows of a range of parities together, although the impacts are largely unknown. This study examined the behavioral expression at mixing for young, midparity, and...
Maternal Behavior, Posture Change, and Production Performance of Lactating Sows Housed in an Enriched Environment
| Contributor(s):: Yi, Ran, Wang, Chao, Zhang, Xin, Zhao, Peng, Zhang, Mingyue, Li, Xiang, Cui, Shiquan, Liu, Honggui, Bao, Jun
This study aimed to evaluate whether adding straw to a loose-farrowing house promotes maternal functions and production. Forty-eight sows (Landrace× Large White) were housed in either a farrowing pen without straw (C, n = 24) or with straw (S, n = 24). Behaviors were observed using video...
Prepartum nest-building has an impact on postpartum nursing performance and maternal behaviour in early lactating sows
| Contributor(s):: Yun, Jinhyeon, Swan, Kirsi-Marja, Farmer, Chantal, Oliviero, Claudio, Peltoniemi, Olli, Valros, Anna
The effects of facilitating prepartum nest-building (NB) behaviour, by providing abundant nesting materials, on postpartum maternal characteristics in early lactating sows were evaluated. A total of 35 sows, approximately seven days before the expected parturition date, were housed in: (1) CRATE...
Learning performance of gestating sows called to the feeder
| Contributor(s):: Kirchner, Jasmin, Manteuffel, Christian, Manteuffel, Gerhard, Schrader, Lars
A call feeding station in which sows learn to be allowed to enter a feeding station only after being called by an individual acoustic signal has been shown to reduce agonistic interactions in front of the feeding station. Here, we tested important prerequisites for integration of a call feeding...
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...
Hierarchy formation in newly mixed, group housed sows and management strategies aimed at reducing its impact
| Contributor(s):: Greenwood, Emma C., Plush, Kate J., van Wettere, William H. E. J., Hughes, Paul E.
Aggression is at its highest when sows are first introduced to new animals and hierarchies are being established. Thus, methods to reduce aggression should focus on this period. The aggression that occurs during mixing results in physiological stress responses, which can have detrimental effects...
The effects of the light regimen imposed during lactation on the performance and behaviour of sows and their litters
| Contributor(s):: Simitzis, Panagiotis E., Veis, Dimitrios, Demiris, Nikos, Charismiadou, Maria A., Ayoutanti, Anna, Deligeorgis, Stelios G.
The objective of the present study was to highlight the possible effects of an extended photoperiod throughout lactation on the performance and behaviour of sows and their piglets. Sows were randomly assigned to two light regimens: (1) standard (n=12) consisting of 8h of light (0700–1500) daily...
