The physiological and behavioural impact of sensory contact among unfamiliar adult mice in the laboratory
Contributor(s):: Rettich, A., Kasermann, H. P., Pelczar, P., Burki, K., Arras, M.
Housing mice in the laboratory in groups enables social interaction and is the way a laboratory should house mice. However, adult males show reciprocal aggression and are therefore frequently housed individually. Alternatively, a grid divider, which allows sensory contact by sight and smell but...
Human-dog interactions and behavioural responses of village dogs in coastal villages in Michoacan, Mexico
Contributor(s):: Ruiz-Izaguirre, E., Eilers, K. H. A. M., Bokkers, E. A. M., Ortolani, A., Ortega-Pacheco, A., Boer, I. J. M. de
In Mexican villages, most households keep dogs that roam freely. Therefore, socialisation of village dogs occurs in a different context than that of companion dogs in developed countries. The objectives of this study were: (1) to assess village dogs' behavioural responses towards familiar and...
Effects of grackle damage control techniques in citrus on nesting success of non-target species
Contributor(s):: John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores
Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning...
Metal concentrations in blood from an adult bald eagle nesting at Clinton Reservoir in Kansas
Contributor(s):: George T. Allen
Concentrations of metals in blood from an adult male bald eagle nesting at Clinton Reservoir in eastern Kansas in 1991 were analyzed by induction coupled plasma emission spectroscopy without preconcentration.Because there are very limited data on background levels of most metals in bald eagle...

Characteristics of wild pig farrowing nests and beds in the upper Coastal Plain of South Carolina
Contributor(s):: Mayer, J. J., Martin, F. D., Brisbin, I. L., Jr.
Thirteen farrowing nests and 9 resting/loafing beds built by wild pigs (Sus scrofa) from an introduced population in South Carolina, USA, were studied with respect to physical description, size parameters, the animals involved, and adjacent surroundings. The nests, built by pre-parturition sows,...
Determinants of reproductive success in force-re-paired cockatiels ( Nymphicus hollandicus )
Contributor(s):: Stone, E. G., Millam, J. R., El-Halawani, M. E., Phillips, R. E., Redig, P. T.
58 previously paired cockatiels were re-paired with mates with which they had never been previously paired. Males (M) and females (F) were assigned a breeding history that was 'experienced' (E) or 'inexperienced' (I), depending on whether they were part of a pair that had hatched at least one egg...
Development with age of nest box use and gregarious nesting in laying hens
Contributor(s):: Riber, A. B.
Use of nest boxes is an important part of the behavioural repertoire of laying hens kept under commercial conditions. A special form of nest box use is gregarious nesting, which occurs when a hen given the choice between an occupied and an unoccupied nest site chooses the occupied nest site....
Influence of environmental stimuli on nest building and farrowing behaviour in domestic sows
Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S., Jorgensen, E.
The effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined using a 2 x 2 factorial design with 9 replicates of 4 multiparous sows. From 1 week prepartum until 2 weeks after farrowing, sows were penned individually in roofed 7.6 msuperscript 2...
Nest building and farrowing in sows: relation to the reaction pattern during stress, farrowing environment and experience
Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S.
Nest building and farrowing behaviour of 40 Landrace/Yorkshire (L/Y) sows was studied in their first and second parity. In the first parity, the gilts were either housed in a crate or a "get-away-pen" (GAP) and in the second parity, either the same farrowing environment was used again or the sow...
Nursing behaviour, postpartum activity and reactivity in sows: effects of farrowing environment, previous experience and temperament
Postpartum behaviour during the first 24 h after farrowing (day 0 pp) and on day 10 pp of 40 Landrace/Yorkshire sows was studied in their first and second parity in a crossover experiment regarding farrowing environment (crate vs. get-away-pen (GAP)). The behaviour was compared with the...
Periparturient nest building: implications for parturition, kit survival, maternal stress and behaviour in farmed mink ( Mustela vison )
Contributor(s):: Malmkvist, J., Palme, R.
Several types of nesting materials with different capacity as substrate for nest building are currently supplied to farmed mink. We investigated whether different nesting resources and possibility of performing periparturient nest-building influenced (a) the parturition, (b) the vitality and...
The impact of social factors on nesting in laying hens ( Gallus gallus domesticus )
Contributor(s):: Lundberg, A., Keeling, L. J.
The effects of competition and disturbances on nest-site selection were studied in commercial laying hens. Hens were housed in 16-litter floor pens (15, 30, 60 and 120 hens per group x 4 replicates) and the levels of aggression and disturbances were compared between nest boxes and pen corners....
Thwarting of behaviour in different contexts and the gakel-call in the laying hen
Contributor(s):: Zimmerman, P. H., Koene, P., Hooff, J. A. R. A. M. van
Earlier studies have shown that thwarting of feeding behaviour in the laying hen is expressed through a specific vocalization, the gakel-call. The first aim of this study was to investigate whether the effect of deprivation per se on the occurrence of gakel-calls can be distinguished from the...
Deprivation of straw bedding alters PGF<sub>2 alpha </sub>-induced nesting behaviour in female pigs
Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Gilbert, C. L.
Sows are highly motivated to build a maternal nest on the day preceding parturition. A model for nest building has been established in pigs, in which exogenously administered prostaglandin F2 alpha (PGF2 alpha ) may be used to elicit nesting behaviour in cyclic, pseudopregnant and pregnant pigs....
Does feed-back from a nest affect periparturient behaviour, heart rate and circulatory cortisol and oxytocin in gilts?
Contributor(s):: Damm, B. I., Pedersen, L. J., Marchant-Forde, J. N., Gilbert, C. L.
To determine the effects of feed-back from a farrowing nest on periparturient behaviour, heart rate and hormones, 20 gilts housed in Schmid pens were permitted to build a nest of peat, straw and branches. Ten gilts then had their nest removed (NR) 10 h after the onset of nest-building and again...

PGF<sub>2 alpha </sub>-induced nest building and choice behaviour in female domestic pigs
Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Johnston, A. N. B.
The domestic pig, Sus scrofa, builds a maternal nest in the day before parturition. A model for porcine nest building has been established, in which exogenously administered prostaglandin (PG)F2 alpha is used to induce nesting behaviour in cyclic, pseudopregnant and pregnant pigs. This...
