Prenatal stress puzzle, the oxytocin piece: Prenatal stress alters the behaviour and autonomic regulation in piglets, insights from oxytocin
Contributor(s):: Rault, Jean-Loup, Mack, Laurie A., Carter, C. Sue, Garner, Joseph P., Marchant-Forde, Jeremy N., Richert, Brian T., Lay, Donald C.
Developmental changes in response to prenatal stressors (PNS) can result in anxiety and abnormal social development in the offspring. Oxytocin (OT) reduces anxiety, whereas OT deficiencies are associated with social behaviour deficits. Hence, we hypothesized that OT could reverse some of the PNS...
Litter competition during nursings and its effect on sow response on Day 2 postpartum
Contributor(s):: Bozděchová, Barbora, Illmann, Gudrun, Andersen, Inger Lise, Haman, Jiří, Ehrlenbruch, Rebecca
The aim of the present study was to assess neonatal sibling competition during nursing on Day 2 postpartum (pp) as well as its effect on the sow's responses. A total of 41 healthy loose-housed sows and their piglets were directly observed and video recorded for 6h on Day 2 pp. Piglet behaviours...
Early recognition of offspring vocalisation by mink mothers
Contributor(s):: Malmkvist, Jens
Mink deliver around the same time of year. Consequently, mink dams are exposed to other delivering dams and litters nearby in the same housing facility on farms. In addition, farmers often transfer kits between litters within the first week of life, as levelling large litters is believed to...
Trade-offs between litter size and offspring fitness in domestic pigs subjected to different genetic selection pressures
Contributor(s):: Ocepek, Marko, Newberry, Ruth C., Andersen, Inger Lise
Artificial selection of the domestic pig (Sus scrofa domesticus) offers a useful model for investigating changes in behaviour associated with reproductive trade-offs between litter size and fitness of offspring. The aim of this study was to evaluate effects of litter size on teat stimulation,...
Do sows respond to sibling competition at the udder Day 1 post-partum?
Contributor(s):: Illmann, Gudrun, Leszkowová, Iva, Šimečková, Marie
The aim of the present follow-up study was to assess sibling competition during nursing on Day 1 post-partum (i.e., 24 h after the end of parturition), as well as whether sows respond to increased sibling competition. A total of 19 healthy sows and their piglets were directly observed and video...
Mate choice, maternal investment and implications for ostrich welfare in a farming environment
Contributor(s):: Bonato, M., Cherry, M. I., Cloete, S. W. P.
At present, the ostrich industry is inefficient, on account of being characterised by inadequate egg production, high embryo mortality, poor chick survival and suboptimal growth rates. However, as ostrich farming commenced only in the mid 19th century in South Africa, farmed ostriches have had a...
Flight distance and reaction to fawn handling are greater in high- than in low-ranked pampas deer ( Ozotoceros bezoarticus) females
Contributor(s):: Ungerfeld, R., Morales-Pineyrua, J. T., Freitas-de-Melo, A.
The flight distance from humans and the reaction of the mother to human handling of their offspring are measures that can be used to assess the quality of the human-animal relationship which could vary according to animals' position in a group. The objective was to determine if the flight...
Pregnant cattle associations and links to maternal reciprocity
Contributor(s):: Swain, D. L., Patison, K. P., Heath, B. M., Bishop-Hurley, G. J., Finger, A.
Cattle are a highly gregarious species that form strong social connections. Social support following calving serves to increase offspring survival and conception rates for the following breeding season. It has been shown that cattle change their association preferences following calving, but the...
Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink
Contributor(s):: Malmkvist, J., Palme, R.
Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...
Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator
Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.
Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...
Evaluating the effect of semi-group housing of rabbit does on their offspring's fearfulness: can we use the open-field test?
Contributor(s):: Buijs, S., Tuyttens, F. A. M.
Breeding does are usually housed one doe per cage, but there is an increased interest in (semi-)group housing systems designed to improve welfare. However, there is a lack of information on how such systems actually affect different aspects of rabbit welfare. We aimed to discern differences in...
Aggression and welfare in a common aquarium fish, the Midas cichlid
Contributor(s):: Oldfield, R. G.
Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively in order to defend resources such as food, shelter, mates, and offspring. The decision to defend...
Dog breeding in New Providence, the Bahamas, and its potential impact on the roaming dog population I: planned and accidental
Contributor(s):: Fielding, W. J.
This article reports the first known study on dog breeding in an Afro-Caribbean community. The study obtained the information on 517 matings through interviews with dog caregivers. Few litters (6.8%) from mongrels (potcakes) resulted from planned matings, whereas 66.5% of matings between purebred...

All a mother's fault? Transmission of stereotypy in striped mice Rhabdomys
Contributor(s):: Jones, M., Lierop, M. van, Pillay, N.
Environmentally induced stereotypy is the most common abnormal behaviour in captive animals. However, not all animals housed in identically impoverished environments develop stereotypy, possibly because of differences in genetic predisposition. To investigate the transmission of stereotypy in...
Birth weight variation in the domestic pig: effects on offspring survival, weight gain and suckling behaviour
Contributor(s):: Milligan, B. N., Fraser, D., Kramer, D. L.
In domestic pigs, litter-mates often vary considerably in birth weight. To examine whether this size variation influences piglet survival, weight gain and suckling behaviour, we experimentally manipulated the number and size distribution of litter-mates in 51 litters. Litters were small (eight or...
Early social experience influences the development of stereotypic behaviour in captive-born striped mice Rhabdomys
Contributor(s):: Jones, M. A., Mason, G., Pillay, N.
The early life experience of captive animals, in combination with their genetic inheritance, can predispose or promote the development of stereotypic behaviour in later life. To investigate the early social effects of weaning age and the presence/absence of the father on the development of...
