A note on the influence of visual conspecific contact on the behaviour of sheltered dogs
Contributor(s):: Wells, D. L., Hepper, P. G.
The effects of visual contact with other dogs on the behaviour of dogs housed in a rescue shelter were examined. 407 dogs were studied: 212 dogs were housed in cages that allowed for visual contact with dogs in opposite pens; 195 dogs were deprived of visual contact with other dogs by being...
A sequential analysis of eliminative behaviour in domestic pigs
Contributor(s):: Wechsler, B., Bachmann, I.
Knowledge of eliminative behaviour in pigs is of much importance for the design of housing systems in order to minimise soiling of the lying area. 53 piglets, 136 fatteners, 272 finishers and 277 sows were observed as focal animals at regularly used dunging areas in a highly structured housing...
An ethological approach to housing requirements of golden hamsters, Mongolian gerbils and fat sand rats in the laboratory - a review
Contributor(s):: Sorensen, D. B., Krohn, T., Hansen, H. N., Ottesen, J. L., Hansen, A. K.
When housing hamsters and gerbils little has been done to identify the preferences of these species. The solitary nature of fat sand rats and hamsters is often discordant with housing practices in animal laboratories. This article provides a comparison of the behaviour of wild-living animals with...
Behaviour and distribution of fattening pigs in the multi-activity pen
Contributor(s):: Simonsen, H. B.
Five groups of fattening pigs were observed in an experimental multi-activity pen with environmental enrichment. The pen measuring 36 msuperscript 2 included sections containing straw, feed and water connected by two corridors. In addition the pigs had access to straw racks, a shower and...
Behaviour and production of laying hens in three prototypes of cages incorporating nests
Contributor(s):: Sherwin, C. M., Nicol, C. J.
Laying hens were housed in groups of 4 in 3 prototypes of cage, each incorporating 4 roll-away nest hollows. Observation on behaviour and production were conducted for 111 days. The hens consistently laid eggs in the nests despite their rudimentary design. The choice of nest for oviposition was...
Behaviour of fattening pigs in a labyrinth pen with environmental variation
Contributor(s):: Simonsen, H. B., Agger, J. F.
Social interactions and the use of feeders, water nipples and a shower were recorded for 8 pigs in an experimental pen. The incidence rate of the total number of social interactions was highest (3.55 per 15 pig-minutes) in the water supply section and lowest in the straw section (1.97 per 15...

Development of tongue-playing in artificially reared calves: effects of offering a dummy-teat, feeding of short cut hay and housing system
Contributor(s):: Seo, T., Sato, S., Kosaka, K., Sakamoto, N., Tokumoto, K., Katoh, K.
16 artificially reared Japanese Black calves were divided into 6 groups: offered a dummy teat or not; given short or long cut hay; and housed individually or in a group. Grooming as common displacement behaviour and physiological stress indicators such as plasma ACTH and cortisol concentration...
Effect of feed and environmental enrichment on development of stereotypic wire-gnawing in laboratory mice
Contributor(s):: Wurbel, H., Chapman, R., Rutland, C.
At 21 days of age, 16 pairs of male ICR laboratory mice were weaned and allocated to 4 treatment groups in a 2 x 2 factorial design matched for genetic background (litter) and body weight. Factor one was the hardness of feed pellets with a significant 2.5-fold difference between soft and hard...
Effect of housing on in situ postures of gestating gilts
Contributor(s):: Taylor, L., Friend, T., Smith, L. A.
Behaviour of gilts housed in tethered housing, crates, loose housing or dirtlot was video-recorded for 48-h observation periods commencing on days 0, 7 and 63. Lying was the most frequent activity, ranging from 65 to 90
Effects of cage-front design on the feeding behaviour of laying hens
Contributor(s):: Sherwin, C. M., Alvey, D. M., Williamson, J. D.
The effects on feeding behaviour of 4 cage-front designs: vertical bars, horizontal bars, feed trough raised 33 cm, and feed trough enclosed within the cage, were examined. Cage-front design had no significant effect on mean feeding-bout duration (range of 69-85 seconds) or proportion of time...
Effects of individual vs. group rearing on the sexual behaviour of prepuberal beef bulls: mount orientation and sexual responsiveness
Contributor(s):: Silver, G. V., Price, E. O.
Ten Hereford bulls were reared from birth in 2 groups of 5 animals, and 10 bulls were physically isolated in individual pens. At 3, 4.5 and 6 months of age, they were all exposed to adult oestrous [female][female]. Individually-raised bulls initially exhibited a significantly higher proportion of...
Effects of visual cover on farmed red deer behaviour
Contributor(s):: Whittington, C. J., Chamove, A. S.
The behaviour of 20 female red deer in a paddock with no visual cover was observed for 2 weeks. Cover, consisting of 2 shade cloth barriers and hanging plastic strips, was placed in one half of the paddock and the behaviour observed. After replication in a 2nd paddock in reversed order, it was...
Enrichment effects on rhesus monkeys successively housed singly, in pairs, and in groups

Influences of intermittent daily draught on the behaviour of weaned pigs
Contributor(s):: Scheepens, C. J. M., Hessing, M. J. C., Laarakker, E., Schouten, W. G. P., Tielen, M. J. M.
The influence of time-unpredictable draught (forced cold air) on the behaviour of pigs was observed in a climate-controlled pig house with 2 identical rooms each with 5 pens. Two days after farrowing, pigs were matched pairwise to correct for genetic, weight and sex differences, and weaning at an...

Open-field test behaviour of growing swine maintained on a concrete floor and a pasture
Contributor(s):: Taylor, L., Friend, T. H.
Open-field test behaviours of 5 barrows and 5 gilts from each of two housing treatments were recorded for 5-minute periods. The pigs had been housed in their respective systems (pasture or concrete floor) for 6 weeks and averaged 18 weeks old at the time of the experiment. The 38 x 198-m pasture...
Sow body movements that crush piglets: a comparison between two types of farrowing accommodation
Contributor(s):: Weary, D. M., Pajor, E. A., Fraser, D., Honkanen, A. M.
The behavior of 20 sows and their litters kept in farrowing crates or more open pens was video recorded for 4 days after farrowing. 24 piglets were killed by maternal crushing during the study (4 in the farrowing crates, 20 in the pens). On 98 other occasions (30 in the farrowing crates, 68 in...
Stereotypies, aggression and the feeding schedules of tethered sows
Contributor(s):: Rushen, J. P.
Thirty, adult, pregnant, tethered sows were observed for 5 min every 0.5 h for 9 h spanning the 2 feeding periods. Activity, consisting largely of food-searching behaviour and drinking, was largely restricted to two 2-h periods following each feed. Three categories of stereotyped behaviour were...

Contributor(s):: Winskill, L. C., Waran, N. K., Young, R. J.
A foraging device for horses was developed by modifying the 'Edinburgh Foodball' (British Patent Application 9200499.3). The Foodball comprised a cylinder shaped casing with a feed dispensing hole and an internal feed store. Five Standardbred, individually stabled horses were observed in their...
