  1. Influence of prior exposure to wood shavings on feather pecking, dustbathing and foraging in adult laying hens

    Contributor(s):: Nicol, C. J., Lindberg, A. C., Phillips, A. J., Pope, S. J., Wilkins, L. J., Green, L. E.

    It has been proposed that chicks acquire substrate preferences during an early 'sensitive' period. If a suitable substrate is absent during this period birds may develop alternative preferences for pecking at feathers. The aim of this study was to examine whether early substrate exposure has...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. Navigational ability in the domestic fowl ( Gallus gallus domesticus )

    Contributor(s):: Zimmerman, P. H., Pope, S. J., Guilford, T., Nicol, C. J.

    Little is known about the navigational abilities of domestic fowl. The question of how chickens represent and orient in space becomes relevant when they are kept in non-cage systems. Since the sun is known to be the dominant spatial organizer in other diurnal bird species, we started our...

  7. Postingestive feedback from starch influences the ingestive behaviour of sheep consuming wheat straw

    Contributor(s):: Villalba, J. J., Provenza, F. D.

    Plant species present a complex array of biochemicals to herbivores that in conjunction with a plant's physical structure influence intake. The role of postingestive feedback from macronutrients on the ingestion of a low-quality forage by sheep was investigated. The ingestive behaviour of 2...

  8. Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity

    Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.

    This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...

  9. Sociability and the willingness of individual sheep to move away from their companions in order to graze

    Contributor(s):: Sibbald, A. M., Hooper, R. J.

    In environments where vegetation is distributed in discrete patches, sheep may have to make a trade-off between being close to companions or moving away to graze better vegetation. In this event, high levels of social motivation may result in lower intakes or diet quality. We investigated whether...

  10. Social versus exploration and foraging motivation in young red junglefowl ( Gallus gallus ) and White Leghorn layers

    Contributor(s):: Vaisanen, J., Jensen, P.

    Social coherence tendency is an important behavioural characteristic in young fowl related to an underlying social motivation that can be modified by breeding. Our aim was to investigate if selection for productive traits in a certain White Leghorn layer strain has influenced different components...

  11. Survey of breeders' management of horses in Europe, North America and Australia: comparison of factors associated with the development of abnormal behaviour

    Contributor(s):: Parker, M., Goodwin, D., Redhead, E. S.

    An online survey of domestic horse breeders in the USA, UK, Australia, Canada and mainland Europe was carried out in order to examine management risk factors associated with the development of abnormal behaviour patterns. One hundred and forty breeders responded, and epidemiological results...

  12. The effect of breed and housing system on dairy cow feeding and lying behaviour

    Contributor(s):: O'Driscoll, K., Boyle, L., Hanlon, A.

    In Ireland there is growing interest in managing dairy cows on out-wintering pads (OWPs) during the winter, as a low cost alternative to housing indoors. This study investigated feeding and lying behaviour of two breeds of dairy cow (Holstein-Friesian and Norwegian Red) at pasture (PAS) and in...

  13. The effect of nose rings on the exploratory behaviour of outdoor gilts exposed to different tests

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

    Rooting behaviour appears to be an important part of the behavioural repertoire in pigs. It is suggested that it is in fact a behavioural need. The present study investigated whether nose-ringed gilts, which are unable to root, can satisfactorily substitute rooting with other exploratory...

  14. Use of a tri-axial accelerometer for automated recording and classification of goats' grazing behaviour

    Contributor(s):: Moreau, M., Siebert, S., Buerkert, A., Schlecht, E.

    The suitability of an inexpensive tri-axial accelerometer for the automated recording of goats' activities at pasture was tested on a slightly undulating pasture in Central Germany (52 h of registry) and on a rugged mountainous pasture in northern Oman (70 h of registry). The logger was either...

  15. A brief note about cow lying behaviour - do cows choose left and right lying side equally?

    Contributor(s):: Forsberg, A. M., Pettersson, G., Ljungberg, T., Svennersten-Sjaunja, K.

    The factors influencing cows' lying behaviour are not fully evaluated. Most studies dealing with lying behaviour were primarily aimed at comparing different designs for the resting area and floor surfaces, while only a few studies have investigated the cows' preference of lying side. The aim of...

  16. A note on using a laser-based technique for recording of behaviour and location of free-ranging animals

    Contributor(s):: Fehmi, J. S., Laca, E. A.

    We developed a precise, remote (up to 300 m) observation system to record animal location and behaviour that requires no animal handling or disruption of the normal environment. Our system, combining a survey laser and a laptop, also allows recording of observed animal behaviour from seconds to...

  17. A note on visual, olfactory and spatial cue use in foraging behavior of pigs: indirectly assessing cognitive abilities

    Contributor(s):: Croney, C. C., Adams, K. M., Washington, C. G., Stricklin, W. R.

    The micro pig's (Sus scrofa) ability to use visual, olfactory and spatial cues to locate a food resource in a novel environment was investigated. In Experiment 1, four castrated male pigs were trained to identify a food resource - one of two plastic flower-pots placed within a 12.8 m x 6.7 m...

  18. Artificial illumination reduces bait-take by small rainforest mammals

    Contributor(s):: Bengsen, A. J., Leung, L. K. P., Lapidge, S. J., Gordon, I. J.

    Small mammals often moderate their foraging behaviour in response to cues indicating a high local predation risk. We assessed the ability of cues associated with a high predation risk to reduce the consumption of bait by non-target small mammal species in a tropical rainforest, without inhibiting...

  19. Behavioural patterns of heifers under intensive and extensive continuous grazing on species-rich pasture in the Czech Republic

    Contributor(s):: Hejcmanova, P., Stejskalova, M., Pavlu, V., Hejcman, M.

    This study examines the effects of season and of two grazing intensities, namely extensive grazing (EG) and intensive grazing (IG), on the grazing behaviour of heifers on species-rich upland pasture in the Czech Republic. Ten or eight (IG), and six or four (EG) heifers were continuously stocked...

  20. Behavioural time budgets of broiler chickens reared in varying light intensities

    Contributor(s):: Alvino, G. M., Archer, G. S., Mench, J. A.

    Light management is a critical component of production for intensively housed animals. To increase productivity, broiler chickens are often raised commercially in houses that are dimly illuminated on a near-continuous basis. There have been relatively few studies examining the effects of light...
