Cage use and feeding height preferences of captive common marmosets ( Callithrix j. jacchus ) in two-tier cages
Contributor(s):: Buchanan-Smith, H. M., Shand, C., Morris, K.
Determining appropriate feeding regimes has important welfare implications for captive primates. This study examined the preference of food bowl heights in 6 pairs of common marmosets (Callithrix jacchus) housed in a 2-tier cage system. Given that marmosets are arboreal and spend most of their...
The effect of the captive environment on activity of captive cotton-top tamarins ( Saguinus oedipus )
Contributor(s):: Burrell, A. M., Altman, J. D.
This study examined captive cotton-top tamarin (Saguinus oedipus) behaviour across 3 different exhibits: (a) a rain forest (30.5 m in diameter), where tamarins free-ranged with other species; (b) a caged outdoor exhibit (5 m in diameter); and (c) a caged enclosure, with access indoors (6x9 m) and...

An automatic system to record foraging behaviour in free-ranging ruminants
Contributor(s):: Rutter, S. M., Champion, R. A., Penning, P. D.
Precise measurements of grazing behaviour are required to develop an understanding of the factors affecting the foraging behaviour of free-ranging domestic ruminants. An automatic, microcomputer-based system for the digital recording of the jaw movements of free-ranging cattle and sheep is...
Cockatiels ( Nymphicus hollandicus ) reject very low levels of plant secondary compounds
Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.
The rejection thresholds of caged cockatiels (Nymphicus hollandicus) were tested to determine their sensitivity to plant secondary compounds. Both alkaloids and tannins were tested using a two-bottle method in which purified water was always available in one bottle and an aqueous test solution...
Dietary preference of dairy heifers grazing ryegrass and white clover, with and without an anti-bloat treatment
Contributor(s):: Rutter, S. M., Orr, R. J., Yarrow, N. H., Champion, R. A.
The effect of an antibloat treatment on the dietary preference of nonpregnant Holstein x Friesian heifers for ryegrass and white clover was studied. Eight groups of two heifers grazed 0.51 ha plots containing adjacent monocultures of grass alongside clover with either 25 or 75% clover (by ground...
Equine ingestion of haylage harvested at different plant maturity stages
Contributor(s):: Muller, C. E.
The influence of plant maturity at harvest of haylage on equine ingestion times and ingestive behaviour was studied. Haylage was harvested at three different occasions: June, July and August, from the primary growth of the same grass-dominated sward. Twelve adult horses of European warmblood type...
Feeding, resting and social behaviour in ewes housed in two different group sizes
Contributor(s):: Jorgensen, G. H. M., Andersen, I. L., Berg, S., Boe, K. E.
The aim of this experiment was to investigate the effects of increased group size on eating- and resting behaviour, aggression and feed intake in housed ewes. During an initial period of 14 days 36 adult (2-6 years old) ewes of the domestic Norwegian Dala breed were divided into four groups of 9....
Intake rate during meals and meal duration for sheep in different hunger states, grazing grass or white clover swards
Contributor(s):: Orr, R. J., Penning, P. D., Rutter, S. M., Champion, R. A., Harvey, A., Rook, A. J.
Meal patterns and rates of feed intake by grazing herbivores may be markedly different from those found in housed ruminants and monogastrics. Cumulative intakes over the evening meal (satiety curves) were measured using groups of sheep (Ovis aries) grazing monocultures of white clover (Trifolium...
Introduction of gum Arabic and guar to the diet of captive black-tufted ear marmosets
Contributor(s):: Pupe, R., Tavares, M. C. H., Barros, M.
Gum plays a significant role in the feeding ecology of wild callitrichids and thus is also supplemented to several primate species in captivity. However, little is known about the feeding habits of black tufted-ear marmosets (including gummivory), in both wild and captive populations. Therefore,...
Laterality of lying behaviour in dairy cattle
Contributor(s):: Tucker, C. B., Cox, N. R., Weary, D. M., Spinka, M.
Dairy cattle spend, on average, between 8 and 15 h/d lying down. Our objective was to describe the laterality of lying behaviour and assess several internal and external factors that may affect laterality. Internal factors included time spent and time since eating or lying before choosing to lie...
Reduction in grass eating behaviours in the domestic dog, Canis familiaris , in response to a mild gastrointestinal disturbance
Contributor(s):: McKenzie, S. J., Brown, W. Y., Price, I. R.
Grass eating behaviour in the domestic dog may be related to gastrointestinal distress. To explore this theory, the current study observed grass eating behaviours in dogs fed a standard diet with and without supplementation of a fructo-oligosaccharide (FOS). The FOS diet temporarily induced...
Social isolation affects the motivation to work for food and straw in pigs as measured by operant conditioning techniques
Contributor(s):: Pedersen, L. J., Jensen, M. B., Hansen, S. W., Munksgaard, L., Ladewig, J., Matthews, L.
The following study, carried out in two phases, aimed to determine whether the presence or absence of a companion pig (pig in an adjoining pen during testing) systematically influenced the demand function for food or straw in growing pigs. The demand for food was tested (n=10) in one phase, and...
The imprints created by cattle grazing short sequences of bites on continuous alfalfa swards
Contributor(s):: Ungar, E. D., Griffiths, W. M.
Grazing by cattle on the scale of a single feeding station was studied to determine the patterns of defoliation and bite dimensions in short bite sequences. The sward was a continuous and homogeneous expanse of alfalfa without any imposed patchiness of structure. Treatments were bite sequences of...
The use of a mirror reduces isolation stress in horses being transported by trailer
Contributor(s):: Kay, R., Hall, C.
Horse trailers are a common form of transportation for horses and ponies and often require the animal to travel alone or with a single companion. The current study investigated the effect of transporting horses alone, in company or with an acrylic safety mirror (measuring 81 cm x 61.5 cm) that...
A survey assessment of variables related to stereotypy in captive giraffe and okapi
Contributor(s):: Bashaw, M. J., Tarou, L. R., Maki, T. S., Maple, T. L.
Stereotypic behaviour has been investigated in a wide variety of animals, but little published information is available on this problem in captive exotic ungulates. A survey was used to gather information on the prevalence of stereotypic behaviour in giraffe and okapi and to identify variables...
Feeding strategy in group-housed growing pigs of four different breeds
Contributor(s):: Fernandez, J., Fabrega, E., Soler, J., Tibau, J., Ruiz, J. L., Puigvert, X., Manteca, X.
Feeding strategy was studied in 205 growing boars in two blocks of 116 and 89 pigs of four breeds (Large White, Landrace, Duroc and Pietrain) respectively. Pigs were housed in groups of 12-14 individuals, with a single breed in each group. Feeding patterns were recorded with a computerized feed...
Foraging behaviour of growing pigs on grassland in relation to stocking rate and feed crude protein level
Contributor(s):: Andresen, N., Redbo, I.
The foraging behaviour of pigs was studied with the aim of using this as a resource in a cropping system. Twenty Landrace x Yorkshire x Hampshire growing pigs, divided into 4 groups, were observed for 3 weeks during the summer of 1995 at Ekhaga Research Farm, east of Uppsala. The pigs had an...
