  1. Respect for animal autonomy in bioethical analysis: the case of Automatic Milking Systems (AMS)

    Contributor(s):: Millar, K. M.

    An analysis of the ethical impacts of the use of an Automatic Milking System (AMS) is used as a case study to illustrate the use of a form of bioethical analysis in technology assessment. The approach is based on the Ethical Matrix, where 'impacts' are assessed in terms of (lack of) respect for 3...

  2. Effect of music on voluntary approach of dairy cows to an automatic milking system

    Contributor(s):: Uetake, K., Hurnik, J. F., Johnson, L.

    A group of 19 mid- and late-lactating Holstein cows with 2 months prior experience of twice daily milking in the AMS was used in this study. The cows were housed in a free-stall barn with slatted floors and fed a complete mixed ration using an indoor feeding trough. They were also offered 1.5...

  3. The behaviour of dairy cows in an automatic milking system where selection for milking takes place in the milking stalls

    Contributor(s):: Stefanowska, J., Ipema, A. H., Hendriks, M. M. W. B.

    To reduce the cost and simplify the operation of an automatic milking system (AMS) for dairy farmers, the selection stall was removed and the selection process transferred to the milking stalls. The behaviour of 18 cows in study 1 and 24 in study 2 was investigated. In study 1, 18 cows had free...

  4. The effect of omitted milking on the behaviour of cows in the context of cluster attachment failure during automatic milking

    Contributor(s):: Stefanowska, J., Plavsic, M., Ipema, A. H., Hendriks, M. M. W. B.

    In robotic milking, there is always a slight chance of failure to attach the milking cluster. Attachment failure is most likely for cows whose udder conformation is less convenient for robot attachment. In general, after milking failure, cows try to revisit the milking robot if they are not sent...

  5. 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...

  6. Behaviour associated with feeding and milking of early lactation cows housed in an experimental automatic milking system

    Contributor(s):: Winter, A., Hillerton, J. E.

    Diurnal patterns of behaviour and behaviour associated with the use of an automatic milking stall were recorded at 10-min intervals for 5 consecutive days in 9 cows. All cows were in early lactation and housed in a straw yard. The automatic milking stall was operational between 06.00 and 0.00 h...

  7. Behavioural problems associated with robot milking

    Contributor(s):: Metz, J., Ipema, A. H.

  8. Modifying the posture of cows for automatic milking

    Contributor(s):: Mottram, T. T., Caroff, H., Gilbert, C.

    Automatic milking systems currently being developed require methods of ensuring that cows adopt postures which allow the attachment of teatcups with >=1 robot arm(s). The ideal posture is for the cow to stand still with its hind legs apart and clear of the udder. Accessibility of the teats was...

  9. Relative motivations of dairy cows to be milked or fed in a Y-maze and an automatic milking system

    Contributor(s):: Prescott, N. B., Mottram, T. T., Webster, A. J. F.

    In experiments I and II [year not given], 6 high-yielding (HY, 33.9 litres/day, s.d. 5.4 litres) and 6 low-yielding (LY, 13.8 litres/day, s.d. 1.6 litres) cows were given the choice to be milked or not in a Y-maze 5-times/day every 3.5 h. The mean number of milkings chosen/cow per day during the...

  10. Behaviour of dairy cows under free or forced cow traffic in a simulated automatic milking system environment

    Contributor(s):: Lauwere, C. C. K. de, Hendriks, M. M. W. B., Metz, J. H. M., Schouten, W. G. P.

    The behaviour in 20 crossbred Holstein cows in 3 experiments (Ia, Ib and II) was studied in a cubicle house with a selection system consisting of a selection stall and a concentrate feeder, simulating an automatic milking system (AMS). The study was carried out at the De Ossekampen experimental...

  11. Milking of Brown Swiss and Austrian Simmental cows in a herringbone parlour or an automatic milking unit

    Contributor(s):: Hagen, K., Lexer, D., Palme, R., Troxler, J., Waiblinger, S.

    Automatic milking systems (AMS) are becoming increasingly common on dairy farms and should be evaluated for their effect on cow welfare. Dairy cows' stress responses during normal successful milking in a 2x6 herringbone milking parlour (HMP) were compared with their responses during normal...
