  1. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    | Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal...

  2. Effect of feeding duration and rumen fill on behaviour in dairy cows

    | Contributor(s):: Lindstrom, T., Redbo, I.

    The aim of the present experiment was to test the hypothesis that oral manipulation of feed is a behavioural need in cattle, irrespective of actual rumen load. Twelve rumen fistulated cows were used and subjected to four different treatments: low rumen content+long duration of eating (A), high...

  3. Effect of milkflow rate and presence of a floating nipple on abnormal sucking between dairy calves. (Special issue: Suckling)

    | Contributor(s):: Loberg, J., Lidfors, L.

    The aim of this study was to investigate if access to an artificial teat, compared with an open bucket, would decrease abnormal sucking in calves held in pairs, and if the calves would perform less abnormal sucking if they spent more time drinking or sucking milk. Sixteen calves of Swedish Red...

  4. Effects of amount of milk, milk flow and access to a rubber teat on cross-sucking and non-nutritive sucking in dairy calves. (Special issue: Suckling)

    | Contributor(s):: Jung, J., Lidfors, L.

    The aim of this study was to test the effects of different amounts of milk, rate of milk flow, and access to a teat after milk intake on non-nutritive sucking on an empty teat and on cross-sucking on other calves in Bos taurus dairy calves. An additional aim was to test if calves prefer to...

  5. Effects of qualitative and quantitative food restriction treatments on feeding motivational state and general activity level of growing broiler breeders

    | Contributor(s):: Savory, C. J., Lariviere, J. M.

    Growing broiler breeder chickens are fed restricted rations to limit body weight at sexual maturity. This experiment tested a proposal (Brouns, F. et al. Applied Animal Behaviour Sciience (1994) 39, 215-223.) that feeding motivation is reduced by using qualitative rather than quantitative food...

  6. Effects of space allowance on the grazing behaviour and spacing of sheep

    | Contributor(s):: Sibbald, A. M., Shellard, L. J. F., Smart, T. S.

    In each of two experiments, four groups of 10 female Scottish Blackface sheep grazed for 2 weeks at each of four space allowances, according to a Greco-Latin Square design. Space allowances were 80, 100, 133 or 200 m2 per head in experiment 1 and 50, 67, 100 or 200 m2 per head in experiment 2....

  7. Expression of rooting motivation in gilts following different lengths of deprivation

    | Contributor(s):: Studnitz, M., Jensen, K. H.

    Outdoor sows may be provided with a nose ring in order to prevent them from uprooting the grass. Under semi-natural conditions, sows spend 10-20% of their active time rooting. The welfare consequences of this rooting deprivation depend on the motivation of the behaviour. This experiment examines...

  8. Factors affecting feeding order and social tolerance to kittens in the group-living feral cat ( Felis catus )

    | Contributor(s):: Yamane, A., Emoto, J., Ota, N.

    Three feeding sites on Ainoshima Island, located 7 km off the coast of Shingu (Fukuoka Prefecture) and 3 feeding groups of feral cats (Felis catus) were used in experiments conducted from 23 November to 29 December 1993 from 05.00 to 07.00 h and 16.00 to 18.00 h. Members of each feeding group...

  9. Feeding behaviour of sheep on shrubs in response to contrasting herbaceous cover in rangelands dominated by Cytisus scoparius L

    | Contributor(s):: Pontes, L. da S., Agreil, C., Magda, D., Gleizes, B., Fritz, H.

    The foraging responses of ewes faced with a diversity of feed items and their effects on broom (Cytisus scoparius L.) consumption were examined. The experiment was conducted on a farm in the autumn with ewes (n=33) grazing three small paddocks (0.44 ha on average, for at least 10 days each)...

  10. Feeding enrichment in an opportunistic carnivore: the red fox

    | Contributor(s):: Kistler, C., Hegglin, D., Wurbel, H., Konig, B.

    In captive carnivores, species-specific behaviour is often restricted by inadequate feeding regimens. Feeding live prey is not feasible in most places and food delivery is often highly predictable in space and time which is considerably different from the situation in the wild. As a result,...

  11. Feeding motivation in pregnant sows: effects of fibrous diets in an operant conditioning procedure

    | Contributor(s):: Ramonet, Y., Bolduc, J., Bergeron, R., Robert, S., Meunier-Salaun, M. C.

    The effect of fibrous diets fed to pregnant sows on their feeding motivation was studied by an operant conditioning procedure. Fifteen multiparous pregnant sows were assigned to three dietary treatments, which differed in the nature of the fibrous components, according to a 3 x 3 Latin square...

  12. 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....

  13. Frustration of goal-directed behaviour in swine

    | Contributor(s):: Lewis, N. J.

    Eighteen grower pigs were starved for 1, 2 or 3 h each morning by removing the feeders. On training days, Monday and Tuesday of each week, full feeders were returned to the pigs. On test days, Wednesday to Friday of each week, nonfunctional feeders were placed in the pens. Pigs were videotaped...

  14. Grazing and browsing times of goats with three levels of herbage allowance

    | Contributor(s):: Orihuela, A., Solano, J. J.

    Three adjacent mixed irrigated pastures of grass (Cenchrus ciliaris) and shrub (Leucaena leucocephala) were used. Grass height was maintained at 27, 14 and 7 cm for treatments I, II and III, respectively, while the height of bushes (6666 plants/ha) were all kept at 150 cm. DM availability was...

  15. Importance of alternative foods on the persistence of flavor aversions: implications for applied flavor avoidance learning

    | Contributor(s):: Kimball, B. A., Provenza, F. D., Burritt, E. A.

    We added a novel flavour, citric acid (CA), to a familiar test diet and conditioned an aversion in lambs to the flavored diet using lithium chloride. In 1 h feeding trials, we examined the roles of a novel flavour cue, choice and nutritional quality of alternatives on the persistence of an...

  16. Individual differences in responses of piglets to weaning at different ages

    | Contributor(s):: Mason, S. P., Jarvis, S., Lawrence, A. B.

    Several studies indicate each piglet within a litter is affected differently by weaning and that these individual responses may be altered by the age of the litter at weaning. In the present study, eight litters of individually marked piglets (n=79) were randomly assigned to be weaned at 21 or 35...

  17. Influence of sward height on diet selection by horses

    | Contributor(s):: Naujeck, A., Hill, J., Gibb, M. J.

    Foraging herbivores are often faced with spatial and temporal heterogeneity within the vegetation they have available to graze and therefore have to make decisions where and when to graze. The study reported in this paper investigated the influence of sward height on diet selection by horses...

  18. 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...

  19. Intersucking in dairy cattle - review and questionnaire. (Special Issue: Behaviour and welfare of cattle)

    | Contributor(s):: Lidfors, L., Isberg, L.

    Intersucking is an abnormal behaviour in dairy heifers and cows, and it is defined by one animal sucking the teat of another animal with the intention of sucking milk. The aim of this paper is to review earlier studies on intersucking in dairy cattle and to present results from a questionnaire...

  20. Lambs fed protein or energy imbalanced diets forage in locations and on foods that rectify imbalances

    | Contributor(s):: Scott, L. L., Provenza, F. D.

    Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different...
