  1. Bergeyella zoohelcum isolated from oral cavities of therapy dogs

    Contributor(s):: Muramatsu, Y., Haraya, N., Horie, K., Uchida, L., Kooriyama, T., Suzuki, A., Horiuchi, M.

  2. The effects of age and sex on pain sensitivity in young lambs

    Contributor(s):: Guesgen, Mirjam J., Beausoleil, Ngaio J., Minot, Edward O., Stewart, Mairi, Jones, Geoff, Stafford, Kevin J.

    Lambs routinely undergo painful husbandry procedures including ear tagging, tail docking and castration. Pain early in life is important because it can compromise lamb welfare. Studies of altricial species, such as rodents and humans, suggest that baseline pain sensitivity varies with age and...

  3. Evaluation of moderate and low-powered lasers for dispersing double-crested cormorants from their night roosts

    Contributor(s):: James F. Glahn, Greg Ellis, Paul Fioranelli, Brian S. Dorr

    The double-crested cormorant (Phalacrocorax auritus) is the primary avian predator on the southern catfish industry, estimated to cause $5 million in damage per year. To date, the most effective strategy for alleviating cormorant depredations in areas of intensive catfish production is...

  4. A laser-based method for measuring thermal nociception of cattle

    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...

  5. 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...

  6. Effects of Burdizzo castration on CO<sub>2</sub>; laser induced thermal nociception of Holstein-Friesian calves of different ages

    | Contributor(s):: Ting, S. T. L., Earley, B., Veissier, I., Gupta, S., Crowe, M. A.

    The objective was to investigate the effects of Burdizzo castration on the thermal nociception (stress-induced hypoalgesia) of Holstein-Friesian bull calves of different ages. Calves castrated at 5.5 mo of age were compared with either intact calves of the same age, or calves castrated at 1.5,...
