Pregnant gilt behavior in outdoor and indoor intensive pork production systems
Contributor(s):: Dailey, J. W., McGlone, J. J.
The behaviour of three genotypes of gilts, PIC Camborough-15 (C-15), PIC Camborough-Blue (CB), and YorkxLandrace (YL), were compared in an English-style extensive outdoor production system and an intensive indoor system. Mutually exclusive behaviours were defined and recorded and included...
The behavioural and physiological responses of farmed red deer ( Cervus elaphus ) penned adjacent to other species
Contributor(s):: Abeyesinghe, S. M., Goddard, P. J., Cockram, M. S.
This experiment describes the implications of red deer being kept in pens in close proximity to other species as may occur during abattoir lairage. 20 groups of 5 male yearling red deer were used to study behavioural and physiological responses over a 2-h period to 1 of 5 treatments: red deer...
The effects of some factors associated with transportation on the behavioural and physiological reactions of farmed red deer
Contributor(s):: Grigor, P. N., Goddard, P. J., Cockram, M. S., Rennie, S. C., Macdonald, A. J.
The effects of several aspects of transportation on the behavioural and physiological responses of red deer (Cervus elaphus) were studied. In two experiments conducted in winter and summer, two groups of five adult male castrated red deer (housed at a space allowance of 2.7 msuperscript 2 per...
The relationship between trough height, feather cover and behaviour of laying hens in modified cages
Contributor(s):: Freire, R., Walker, A., Nicol, C. J.
The feather condition and behaviour of ISA Brown laying hens in modified cages with elevated (28 cm above floor) and conventional (6 cm above floor) height feed troughs were measured at 32-34 and 56-59 weeks of age. Feather cover was generally better at the younger age than the older, and in...

A multiple free choice model for pigs
Contributor(s):: Mwanjali, S., Smidt, D., Ellendorff, F.
A model which takes into consideration previous criticism of multiple free choice systems is proposed. A hexagonal housing system was constructed with 6 identical cubicles, which allowed elimination of all variables except the 1 to be investigated. Barriers could be introduced at the entrance to...
Agonistic and mating behavior of adult chickens modified by social and physical environments
Contributor(s):: Craig, J. V., Bhagwat, A. L.
Agonistic and mating behaviour in 48 flocks of adult White Leghorn fowls was observed for 8 wk. A factorial experimental design allowed evaluation of behaviour as affected by genetic strain, presence or absence of males , age group (initial ages of 32 or 48 wk), and less crowded floor pens...
Behavioral responses to short-term social isolation in sheep and goats
Contributor(s):: Price, E. O., Thos, J.
Temporary isolation from social partners under modern husbandry practices is often accompanied by psychological distress. The effects of short-term social isolation were studied in forty ten-week-old domestic sheep and goats reared in intra- and inter-specific pairs. Goats bleated and reared...
Effects of male presence on agonistic behavior and productivity of White Leghorn hens
Contributor(s):: Bhagwat, A. L., Craig, J. V.
Three experiments were performed, involving 18, 16 and 48 flocks with 9-16 females and 0-4 males per flock. The White Leghorn strains used had been selected either for egg mass or age at sexual maturity, or were unselected. Age at 50% egg production, rate of lay, survival rate, egg weight, egg...
Factors affecting lying behaviour and stall utilization of dairy cattle
Contributor(s):: Arave, C. W., Walters, J. L.
Stall usage under relatively uncrowded conditions by 59 dry Holstein cows and 18 heifers in late pregnancy were evaluated during 24-h periods. Left laterality (lying down on the left side) was observed 74.7 plus or minus 1.1% of the time for cows and 61.8 plus or minus 2.7% of the time for...
Fearful behavior by caged hens of two genetic stocks
Contributor(s):: Craig, J. V., Craig, T. P., Dayton, A. D.
Two White Leghorn strains which had both been selected for increased part-year egg mass but differed significantly from each other in agonistic behaviour, and sire families within each strain, were compared for nervousness scores and for latencies to feed and to return to normal activity after...
Observations on the nursing behaviour of beef cows suckling Charolais cross calves
Contributor(s):: Somerville, S. H., Lowman, B. G.
Three separate 48 h observations were made of the suckling behaviour of (1) Hereford X Friesian cows under grazing conditions, (2) Blue Grey cows under grazing conditions, and (3) Blue Grey cows housed. All the cows suckled Charolais cross calves. The mean suckling frequencies recorded were 5.5,...
