Contributor(s):: Blom, H. J. M., Tintelen, G. van, Baumans, V., Broek, J. van den, Beynen, A. C.
The preferences of rats for various heights and light intensities in cages were studied. Preferences were expressed as relative dwelling times (RDT) per cage. In the first experiment, using 9 female and 9 male Wistar rats, the females prefered lower cages (height 80 mm, RDT 29.9
Dominance rank and cage density effects on performance traits, feeding activity and plasma corticosterone levels of laying hens ( Gallus domesticus )
Contributor(s):: Cunningham, D. L., Tienhoven, A. van, Goeijen, F. de
White Leghorn laying fowls were housed 5, 6 and 7 per cage, which provided 430, 358 and 307 cmsuperscript 2 of floor space per bird (low-, moderate- and high-density cage environments resp.). The birds were maintained on a controlled lighting programme of 8L:10D:2L:4D during the production cycle,...
Effects of accommodation type and straw bedding around parturition and during lactation on the behaviour of primiparous sows and survival and growth of piglets to weaning
Contributor(s):: Cronin, G. M., Smith, J. A.
The effects of accommodation type (crate or pen) and bedding (with or without straw) were studied in 64 primiparous sows in 16 replicates. Sows that farrowed without straw had more liveborn piglets than sows with straw (9.4 vs. 9.1; P

Contributor(s):: Dellmeier, G., Friend, T., Gbur, E.
The open-field behaviour of 25 Holstein bull calves maintained in 1 of 4 housing treatments was recorded weekly for 8 weeks to investigate the effects of different methods of confinement on motivation for locomotor and other behaviours, and behavioural ontogeny. Data were modelled as a repeated...
Effects of composition and density of the group on the performance, behaviour and age at puberty in swine
Contributor(s):: Clark, J. R., Bell, R. W., Tribble, L. F., Lennon, A. M.
218 crossbred pigs (Duroc-Hampshire-Landrace-Yorkshire) were assigned to a 2 x 3 factorial experiment, the factors being group composition and density. The group-composition factor consisted of pigs not re-aggregated (group 1), re-aggregated below the median body weight (group 2), and...
Effects of design of individual cage-stalls on the behavioural and physiological responses related to the welfare of pregnant pigs
Contributor(s):: Barnett, J. L., Hemsworth, P. H., Cronin, G. M., Newman, E. A., McCallum, T. H.
This experiment describes the effects of 2 designs of individual cage-stalls on the behavioural and physiological responses of pregnant pigs. There was a total of 32 experimental pigs housed in 2 designs of cage-stalls, vertical or horizontal bars, and 2 control treatments, tether-stalls...
Effects of floor type during rearing and of beak trimming on ground pecking and feather pecking in laying hens
Contributor(s):: Blokhuis, H. J., Haar, J. W. van der
Forty groups of 12 1-day-old chicks of a brown egg-laying strain were housed on either litter (20 groups) or wire floors (20 groups). Ten groups of birds on wire floors and 10 groups on litter floors were beak trimmed at 45 days of age. At 18 weeks of age, each group was moved to one of 40...
Effects of grouping unfamiliar adult pigs after dark, after treatment with amperozide and by using pens with stalls, on aggression, skin lesions and plasma cortisol concentrations
Contributor(s):: Barnett, J. L., Cronin, G. M., McCallum, T. H., Newman, E. A., Hennessy, D. P.
The effects of methods previously shown to reduce aggression were determined following grouping of 4 unfamiliar, adult ovariectomized pigs. There were 4 treatments involving 24 pigs in 6 replicates: (i) Control; (ii) Stall, in which there were 4 partial stalls used for feeding; (iii) Amperozide...
Effects of nest quality and other cues for exploration on pre-laying behaviour
Contributor(s):: Freire, R., Appleby, M. C., Hughes, B. O.
The pre-laying behaviour of 11 hens was observed in pens without or with litter and without or with an exploratory walkway. Hens with unlittered nest boxes had longer durations of pre-laying behaviour (151 vs. 110 min) and spent longer searching (32 vs. 19 min) than those with littered nest...
Effects of pen size, partial stalls and method of feeding on welfare-related behavioural and physiological responses of group-housed pigs
Contributor(s):: Barnett, J. L., Hemsworth, P. H., Cronin, G. M., Newman, E. A., McCallum, T. H., Chilton, D.
Pregnant Large White X Landrace gilts in groups of 4 were housed at 1.97 or 0.9 msuperscript 2/pig, with or without partial stalls and fed within the partial stalls or on the floor of the pen. In the 90 min following grouping of the (unfamiliar) pigs, the presence of the partial stalls reduced...
Effects of pen size/shape and design on aggression when grouping unfamiliar adult pigs
Contributor(s):: Barnett, J. L., Cronin, G. M., McCallum, T. H., Newman, E. A.
The effects of space allowance/pen shape (small square or small rectangular pens providing a space allowance of 1.4 msuperscript 2 per pig and a large pen providing a space allowance of 3.4 msuperscript 2 per pig) and pen design (partial stalls, 0.44 m wide x 0.74 m long, or no stalls) on...

The study examined the effects of housing 24 adult female pigs in groups of 2, 4 or 8 with a space allowance of 1.4msuperscript 2 per pig on welfare status, as indicated by plasma free-corticosteroid concentrations and behaviour patterns, and sexual behaviour. Housing gilts in pairs resulted in...
Effects on behaviour and plumage of a key-stimuli floor and a perch in triple cages for laying hens
Contributor(s):: Braastad, B. O.
Three environmental factors were introduced in various combinations with the aim of reducing feather pecking and improving the plumage and welfare in low-density cages for light-hybrid laying hens (704 cmsuperscript 2 per hen) (i) A floor with key stimuli for ground pecking, consisting of blue...
Feeding order of sows at an individual electronic feed station in a dynamic group-housing system
Contributor(s):: Bressers, H. P. M., Brake, J. H. A. te, Engel, B., Noordhuizen, J. P. T. M.
Patterns in the use of a feed station, by sows, in a dynamic group-housing situation, were studied because deviations from such patterns might indicate disease, oestrus, reproductive or other problems. Groups of 10 sows of various parities were transported to an experimental farm on the day their...

Contributor(s):: Craig, J. V., Okpokho, N. A., Milliken, G. A.
White Leghorn pullets were reared in floor pens and high-density cages and at 18 weeks old put in multiple hen cages. In experiment 1, 48 pullets were kept in 6, 8-bird cages during days 1, 4 and 15 and in experiment 2, 80 pullets were kept in 16, 5-bird cages during days 1 and 7 or 8. In...
