  1. Locomotor activity of dairy cows in relation to season and lactation

    Contributor(s):: Brzozowska, Anna, Łukaszewicz, Marek, Sender, Grażyna, Kolasińska, Dorota, Oprządek, Jolanta

    All systems recording activity of cattle measure it independently of environmental and animal factors. Such recordings may hide differences in activity caused by extraneous interferences or may be inaccurately interpreted. The information produced by sensors could be more accurate, if behaviour...

  2. Lying patterns of high producing healthy dairy cows after calving in commercial herds as affected by age, environmental conditions and production

    Contributor(s):: Steensels, Machteld, Bahr, Claudia, Berckmans, Daniel, Halachmi, Ilan, Antler, Aharon, Maltz, Ephraim

    An animal expresses its physiological and well-being status by its behaviour. Changes in behaviour can be associated with health, production or well-being problems and therefore with the profitability of the farm. The objectives of the present study were to analyse lying patterns of healthy cows,...

  3. Associations between precision sensor data with productivity, health and welfare indicator traits in native black and white dual-purpose cattle under grazing conditions

    Contributor(s):: Jaeger, Maria, Brügemann, Kerstin, Brandt, Horst, König, Sven

    The aim of the study was to analyse the relationships between conventional production as well as subjectively scored welfare assessment traits with longitudinal sensor measurements (i.e., behavioural activity traits) of dual-purpose cattle kept in grazing systems. Such aim implies getting...

  4. Lying patterns of high producing healthy dairy cows after calving in commercial herds as affected by age, environmental conditions and production

    Contributor(s):: Steensels, M., Bahr, C., Berckmans, D., Halachmi, I., Antler, A., Maltz, E.

  5. Are cows more likely to lie down the longer they stand?

    Contributor(s):: Tolkamp, B. J., Haskell, M. J., Langford, F. M., Roberts, D. J., Morgan, C. A.

    Information on (changes in) standing and lying behaviour of cows can be used for oestrus detection, early diagnosis of disorders and to evaluate welfare consequences of changes in housing and management. Data sets on lying and standing behaviour were collected from cows with IceTagTM sensors...

  6. An automatic system to monitor lying, standing and walking behaviour of grazing animals

    Contributor(s):: Champion, R. A., Rutter, S. M., Penning, P. D.

    Sensors incorporating mercury tilt switches were used to measure the lying, standing and walking behaviour of grazing cattle and sheep. The lying/standing sensor was suspended below the animal, whilst the walking sensor was fitted to the shin of the animal's foreleg. Both switches gave a...
