Previous experience with different floors influences choice of peat in a Y-maze by domestic fowl
Contributor(s):: Petherick, J. C., Duncan, I. J. H., Waddington, D.
Chicks of two strains of domestic fowl were reared on either floors of wire (wire reared) or concrete covered with wood shavings with access to peat (litter reared). At 13 weeks of age, the birds were given a choice of wire or peat in a Y-maze. The wire-reared birds tended to choose wire and the...

Suckling behaviour of piglets in relation to accessibility to the sow and the presence of foreign litters
Contributor(s):: Pedersen, L. J., Studnitz, M., Jensen, K. H., Giersing, A. M.
35 sows were distributed to 1 of 3 housing treatments. In treatment GS (group sows-separate piglets), 12 sows were in groups of 4 in a 'get-away system' where the sows could leave the piglets at their own will and where the litters were not able to compete for milk at foreign sows' udders. In...
The effect of agonistic interactions on the heart rate of group-housed sows
Contributor(s):: Marchant, J. N., Mendl, M. T., Rudd, A. R., Broom, D. M.
The heart rates of 9 Large White x Landrace sows housed in a large group with an electronic sow feeder system, were monitored during agonistic interactions. Interactions were categorised into those involving physical contact and non-physical interactions involving threat only. Both were recorded...
The effect of early exposure to the opposite sex on mate choice in White Leghorn chickens
Contributor(s):: Leonard, M. L., Zanette, L., Clinchy, M.
1000 female and 148 male Leghorn fowls were reared in all-female (140/pen), all-male (50/pen) or mixed pens (12 males and 140 females/pen). Males and females reared in mixed pens were separated at 18 weeks of age to prevent them from gaining adult sexual experience. Mate choice trials were...
The effect of environment and stage of the oestrous cycle on the behaviour of dairy cows
Contributor(s):: Phillips, C. J. C., Schofield, S. A.
In a series of 4 experiments, behavioural changes during the perioestrous period of Friesian cows were studied. In the 1st experiment, conducted on 12 cows in cubicles, standing to be mounted was confined to the day of oestrus. Changes in time spent lying or standing in the cubicle or in the...
The effect of environmental stimulation on the development of behaviour in pigs
Contributor(s):: Petersen, V., Simonsen, H. B., Lawson, L. G.
16 litters were reared in barren or enriched environments from birth to slaughter. Enriched pens contained straw, logs and branches, whereas barren pens contained no floor materials or objects. Piglets were weaned at 5 weeks of age. Behaviour was monitored during weeks 4, 7 and 18. Pigs in the...
The effects of pen size on the behaviour of farmed red deer stags confined in yards
Contributor(s):: Pollard, J. C., Littlejohn, R. P.
40 red deer stags (2 years old) were confined for 40 min in large (5 m x 4 m) or small (2.5 m x 4 m) pens on 2 days in spring and summer. Wall pacing and vertical/horizontal head movements at the walls were more frequent in small pens than in large pens and were carried out by a greater...

The maintenance behaviour and cleanliness of pigs in two-tier weaner decks
Contributor(s):: Lewis, N. J., Christison, G. I.
Tiered weaner decks for pigs appear to have a major disadvantage because the faeces and urine from the pigs in the top pens drop through to the pigs in the lower pens. This may affect the well-being of these pigs and may cause the development of poor dunging habits. To determine the general...
Use of nest boxes by young farmed silver foxes ( Vulpes vulpes ) in autumn
Contributor(s):: Mononen, J., Harri, M., Rekila, T., Korhonen, H., Niemela, P.
A standard wire-mesh cage (length 112 cm x width 107 cm x height 70 cm) with a wooden nest box was provided to juvenile silver foxes. The extent to which the nest boxes (dimensions of the main chamber 40 cm x 40 cmx 40 cm; or diameter 38 cm, height 32 cm) were used by 36 foxes kept in pairs and 8...
Use of pen space by broiler chickens: effects of age and pen size
Contributor(s):: Newberry, R. C., Hall, J. W.
An experiment was conducted to investigate the effects of age and pen size on the use of pen space by male broiler chickens. The locations of 18 marked chickens in a large pen (407 msuperscript 2 with 3040 birds) and 10 in each of two small pens (203.5 msuperscript 2 with 1520 birds) were...
A comparison of the effects of two oestrus detection procedures and two housing systems on the oestrus detection rate of female pigs
Contributor(s):: Hemsworth, P. H., Winfield, C. G., Barnett, J. L., Schirmer, B., Hanse, C.
In the 1st experiment, high oestrus detection rates (percentage of cycling gilts that were detected in oestrus) were achieved when cycling gilts which were kept near (but not adjacent to) boars, were checked for oestrus using either the back-pressure test (BPT) in close proximity to boars or a...
A quantitative analysis of social behaviour of different crossbreds of dairy cattle kept in loose housing and its relationship to productivity
Contributor(s):: Jezierski, T. A., Podluzny, M.
The social behaviour of Polish Black-and-White dairy cattle (BW) was compared with that of the F1-crossbreds of BW with Jersey (BW x J), Ayrshire (BW x Ay), Holstein-Friesian (BW x HF) and Swedish Black-and-White (BW x SLB). The crossbreds BW x J proved to be most aggressive, excitable and...
Behaviour of dairy cows kept in extensive (loose housing/pasture) or intensive (tie stall) environments 1. Experimental procedure, facilities, time budgets - diurnal and seasonal conditions
Contributor(s):: Krohn, C. C., Munksgaard, L., Jonasen, B.
Twelve dairy cows were placed in a stimuli-rich environment, a 'dairy cow park', for 2.5 years. The 'park' consisted of an extensive barn with deep bedding, a yard and a pasture. The cows were milked and fed twice a day in the barn, but had free access to the whole area at all times. During the...

Contributor(s):: Held, S. D. E., Turner, R. J., Wootton, R. J.
Groups of adult rabbits in which stable dominance hierarchies had been developed were used in the experiments. In experiment one, 9 low-ranking and 9 high-ranking rabbits were given the choice between a group-pen and a solitary pen; the solitary pen was the same size (2.8 msuperscript 2) and had...
