    Contributor(s):: Veissier, I., Rushen, J., Colwell, D., Passille, A. M. de

    A method is described for measuring nociception in cattle using a CO2 laser aimed at the caudal aspect of the metatarsi. Four experiments were performed, involving 60 Holstein calves. In Experiment 1, infrared thermography showed that calves responded by lifting their legs when skin temperatures...

  6. A new method to measure behavioural activity levels in dairy cows

    Contributor(s):: Muller, R., Schrader, L.

    Changes in the behavioural activity of farm animals are widely used as an indicator for the assessment of animal welfare. In this study on dairy cattle we validated a new method for automatic 24 h recording of behavioural activity, the ActiwatchReg. activity monitoring system (AMS). The AMS is a...

  7. Assessment of animal welfare through behavioural parameters in Iberian pigs in intensive and extensive conditions

    Contributor(s):: Temple, D., Manteca, X., Velarde, A., Dalmau, A.

    Behaviour is a significant component of well-being and should be properly considered in a pig welfare assessment. However, interpretation of variations in behaviour is usually not straightforward, especially when dealing with animals housed and managed in a variety of systems. The fourth...

  8. Behaviour, synchrony and welfare of Pekin ducks in relation to water use

    Contributor(s):: Waitt, C., Jones, T., Dawkins, M. S.

    The method of providing bathing water to commercially farmed ducks presents potential logistic, welfare and health issues. Welfare may be compromised if ducks do not have access to water in which they can at least dip their heads and spread water over their feathers. However maintaining hygiene...

  9. Behavioural responses to hypoxia provide a non-invasive method for distinguishing between stress coping styles in fish

    Contributor(s):: Laursen, D. C., Olsen, H. L., Ruiz-Gomez, M. de L., Winberg, S., Hoglund, E.

    Two divergent behavioural and physiological response patterns to challenges have been identified in mammals and birds, frequently termed the proactive and reactive coping styles. In recent years, individually distinct coping styles have also been observed in several species of fish. These...

  10. Breeding against harmful social behaviours in pigs and chickens: state of the art and the way forward

    Contributor(s):: Turner, S. P.

    Harmful social behaviours are prevalent in commercial farming environments and their reduction through economically feasible husbandry changes is challenging. Selective breeding may offer a complementary approach to reduce the expression of these traits. This article explores the progress made in...

  11. Castration induced pain in pigs and other livestock. (Special Issue: Pain in farm animals.)

    Contributor(s):: Rault, J. L., Lay, D. C., Jr., Marchant-Forde, J. N.

    Castration of male livestock being reared for meat has long been practiced, to prevent unwanted breeding, make management and handling easier, and to improve meat quality. However, castration is a painful procedure for the animal and has increasingly come under scrutiny from animal welfare...

  12. Comparison of methods to assess fear of humans in sows

    Contributor(s):: Scott, K., Laws, D. M., Courboulay, V., Meunier-Salaun, M. C., Edwards, S. A.

    The aims of this study were to compare three different methods to assess fear of humans in sows, and identify the most practical and reliable method for on-farm welfare assessment. Fifty-five crossbred sows (Landrace x Large White x Duroc) of different parities and stages of pregnancy were each...

  13. Cow behaviour pattern recognition using a three-dimensional accelerometer and support vector machines

    Contributor(s):: Martiskainen, P., Jarvinen, M., Skon, J. P., Tiirikainen, J., Kolehmainen, M., Mononen, J.

    Automated animal behaviour monitoring systems have become increasingly appealing for research and animal production management purposes. However, many existing systems are suited to measure only one or two behaviour patterns or activity states at a time. We aimed to develop and pilot a method for...

  14. Development and validation of a new method for visual detection of estrus in mithun ( Bos frontalis )

    Contributor(s):: Mohan, Mondal, Muthupalani, Karunakaran, Chandan, Rajkhowa, Prakash, B. S.

    The objectives of this study were (1) to develop a suitable scoring scale for oestrus detection based on frequency and reliability of behavioural signs of oestrus in mithun (Bos frontalis) and (2) to validate the accuracy of this method for detection of oestrus in primi- and multiparous mithun...

  15. Early prediction of adult police dog efficiency - a longitudinal study

    Contributor(s):: Slabbert, J. M., Odendaal, J. S. J.

    At the South African Police Service Dog Breeding Centre, behaviour tests were developed specifically for police dogs to predict their efficiency as adults. The tests were carried out on 167 puppies between January 1994 and March 1996. The sample consisted of 49 different litters from 34 stud dogs...

Twenty-two dogs, which were never subjected to...

  17. Feeding enrichment in an opportunistic carnivore: the red fox

    Contributor(s):: Kistler, C., Hegglin, D., Wurbel, H., Konig, B.

    In captive carnivores, species-specific behaviour is often restricted by inadequate feeding regimens. Feeding live prey is not feasible in most places and food delivery is often highly predictable in space and time which is considerably different from the situation in the wild. As a result,...

  18. Measurement of feeding motivation in sheep and the effects of food restriction

    Contributor(s):: Verbeek, E., Waas, J. R., McLeay, L., Matthews, L. R.

    The availability of food is a crucial factor determining the health and growth of animals. Prolonged or severe food restriction will trigger the subjective state of hunger, which could potentially reduce welfare. We refined a methodology for the measurement of feeding motivation as an indicator...

  19. Measuring motivation: using the cross point of two demand functions as an assessment of the substitutability of two reinforcers

    Contributor(s):: Sorensen, D. B., Ladewig, J., Matthews, L., Ersboll, A. K., Lawson, L.
