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...

  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. Voluntary automatic milking in combination with grazing of dairy cows. Milking frequency and effects on behaviour

    Contributor(s):: Ketelaar-de Lauwere, C. C., Ipema, A. H., Ouwerkerk, E. N. J. van, Hendriks, M. M. W. B., Metz, J. H. M., Noordhuizen, J. P. T. M., Schouten, W. G. P.

    Grazing was combined with a fully automatic milking system (AMS) for a group of 24 crossbred Holstein cows. It was assumed that the cows would visit the AMS voluntarily. Zero grazing (G0) was compared with restricted grazing (cows could spend up to 12 h outdoors daily; G12) and unrestricted...

  11. 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...

  12. 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...

  13. 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...
