  4. Daily grazing time of dairy cows is recorded accurately using the Lifecorder Plus device

    Contributor(s):: Delagarde, R., Lamberton, P.

    Accurate estimation of daily grazing time and nycthemeral grazing pattern in ruminant nutrition research may result in a better understanding of sward-animal interactions and of the behavioural constraints affecting daily intake at pasture. Portable devices which automatically record grazing...

  5. Effect of feed allowance at pasture on lying behaviour and locomotory ability of dairy cows

    Contributor(s):: O'Driscoll, K., Lewis, E., Kennedy, E.

    In temperate climates where cows are primarily managed at pasture shortages of grass could result in nutritional deficits for the cow and thus pose a challenge to her welfare. This study investigated the effect of daily herbage allowance (DHA) on dairy cow lying behaviour, locomotory ability, and...

  6. Oral behaviors of beef steers in pen and pasture environments

    Contributor(s):: Ishiwata, T., Uetake, K., Kilgour, R. J., Eguchi, Y., Tanaka, T.

    This study observed the behavioral characteristics of 122 steers in eight pens and 1,136 steers at six pastures. Nonhuman animals kept in pens performed less nutritive oral behaviors and more nonnutritive oral behaviors than animals kept at pasture. Although these could not be described as...

  7. Management, health, and abnormal behaviors of horses: a survey in small equestrian centers in Brazil

    Contributor(s):: Leme, D. P., Parsekian, A. B. H., Kanaan, V., Hotzel, M. J.

    Care conditions of horses housed in small equestrian establishments and the occurrence of health and behavioral problems were assessed in 197 animals. Based on questionnaires and direct observations of the animals, it was noted that 8% of all animals were fed exclusively on pasture, whereas 92%...

  8. Activity bout criteria for grazing dairy cows

    Contributor(s):: Rook, A. J., Huckle, C. A.

    Data on the eating, ruminating and idling activity of grazing dairy cows recorded to a resolution of 1 min were used to study the choice of activity bout criteria and the implications of this choice. An inter-bout length of 5 min was found to be suitable for all 3 activity categories across a...

  9. 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...

  10. Diet preference for grass and legumes in free-ranging domestic sheep and cattle: current theory and future application

    Contributor(s):: Rutter, S. M.

    This paper reviews the current theory and potential practical applications of research on the diet preference for grass and legumes in grazing domestic sheep and cattle. Although much of this work has focussed on grass and clover as a model system, it has wider theoretical implications and...

  11. 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...

  12. Diurnal patterns of intake rate by sheep grazing monocultures of ryegrass or white clover

    Contributor(s):: Orr, R. J., Penning, P. D., Harvey, A., Champion, R. A.

    The effects of time of day on the ingestive behaviour of groups of 5 sheep grazing monocultures of ryegrass (Lolium perenne cv. Parcour) or white clover (Trifolium repens cv. Kent Wild White), were measured over periods of 1 h starting at 07.30, 11.30, 15.30 and 19.30 h in August 1993. Grazing...

  13. Effect of dairy cattle husbandry on behavioural patterns of red deer ( Cervus elaphus ) in the Italian Alps

    Contributor(s):: Mattiello, S., Redaelli, W., Carenzi, C., Crimella, C.

    The present study aimed to investigate in the field the effect of the presence of cattle on red deer behavioural patterns, in order to provide information that could be used to improve land management strategies. The research was carried out in a summer range at 1500 m a.s.l. in the Italian...

  14. Effects of social behaviour on the spatial distribution of sheep grazing a complex vegetation mosaic

    Contributor(s):: Sibbald, A. M., Oom, S. P., Hooper, R. J., Anderson, R. M.

    In complex environments, the spatial distribution of preferred food types will be a major factor influencing the distribution of foraging animals. However, in highly social animals, such as sheep, social interactions may modify foraging behaviour and hence influence both where animals feed and...

  15. 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....

  16. 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)...
