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...

Effects of social environment on welfare status and sexual behaviour of female pigs. I. Effects of group size
Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G., Hansen, C.
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...
Floor- and cage-rearing effects on pullets' initial adaptation to multiple-hen cages
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...

Influence of maternal experience on pig behaviour
Contributor(s):: Beattie, V. E., Walker, N., Sneddon, I. A.
29 gilts were housed from birth to farrowing in an intensive barren housing system (B) or in enriched housing (E). A few days before parturition gilts were moved into barren (treatments BB and EB) or enriched farrowing accommodation (treatments EB and EE); the gilts remained in this...

Rearing conditions and needs for space and litter in laying hens
Contributor(s):: Faure, J. M.
Five groups of 4 hens reared in battery cages, and 5 groups of 4 hens reared in floor pens, were tested in an operant conditioning apparatus which allowed the hens to enlarge their cage by key pecking. Cage size could be varied between 1600 and 6100 cmsuperscript 2. The variable size section of...
Research on alternatives to the battery system for laying hens
Contributor(s):: Folsch, D. W., Huber, H. U., Bolter, U., Gozzoli, L.
Alternatives to battery husbandry are described with reference to free-range husbandry, large indoor systems and other alternative systems which have been tested or introduced in various European countries. Factors required for animal welfare in such systems are described, and economics discussed.

Stereotyped behaviour, social interactions and suckling pattern of pigs housed in groups or in single crates
Contributor(s):: Arellano, P. E., Pijoan, C., Jacobson, L. D., Algers, B.
The frequency of stereotypies, the nature of social interactions and whether sows or piglets initiate and terminate successful sucklings were compared. Sows on a commercial farm were housed in either crates or pens and studied for a year. Sows in crates developed significantly more stereotypies...
Suckling behaviour of sows in farrowing crates and straw-bedded pens
Contributor(s):: Cronin, G. M., Smith, J. A.
The behaviour of 18 primiparous Large White (LW) or LW X Duroc sows and their litters was observed during 6 days in lactation (1, 2, 3, 7, 14 and 21) in 2 housing treatments: (1) farrowing crate (1.6 m x 2.2 m) without straw; (2) farrowing pen (2.8 m x 2.8 m) with straw added. After farrowing,...
The development of agonistic behaviour in relation to the size of the farrowing pen
Contributor(s):: Duijghuisen, J. A. H.
The development of agonistic behaviour of piglets in two types of farrowing pen and their later behaviour as sows in groups was investigated. One type of farrowing pen was 3.85 msuperscript 2, the other was 6.85 msuperscript 2. In both types, agonistic interactions were analysed at an age of 2, 3...
The effects of design of individual stalls on the social behaviour and physiological responses related to the welfare of pregnant pigs
Contributor(s):: Barnett, J. L., Hemsworth, P. H., Winfield, C. G.
Plasma free-corticosteroid concentrations, aggressive behaviour and levels of motivation to interact socially and explore a novel environment were observed to test the hypothesis that the chronic stress response previously observed in tether-housed pigs may have been due to unresolved aggression...
