  1. Are double bunks used by indoor wintering sheep? Testing a proposal for organic farming in Norway

    Contributor(s):: Hansen, I., Lind, V.

    The frequency with which ewe lambs lay on wooden surfaces at two levels, called "double bunks," was documented by video recording at 6, 11 and 18 months of age: the number in each of 4 pens (n=4) lying either on double bunks (DBs) or on the expanded metal floor (EMF) was recorded. At 6 months,...

  2. An evaluation of the contribution of isolation, up-ending and wool removal to the stress response to shearing

    Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    A 2x2x2 factorial experiment examined the effects of 3 components of shearing (isolation, up-ending and wool removal) on the development of a stress response to handling. 10 Merino wethers were allocated to each treatment. Haematocrit, plasma cortisol and plasma glucose were measured in a series...

  3. Changes in heart rate, plasma cortisol and haematocrit of sheep during a shearing procedure

    Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    Nine Merino wethers were individually subjected to a series of 8 handling treatments of increasing complexity, culminating in partial shearing. The treatments were control, separation from other sheep, isolation, human presence, blood sampling, up-ending, exposure to shearing noise, and wool...

  4. The stress response in sheep during routine handling procedures

    Contributor(s):: Hargreaves, A. L., Hutson, G. D.

    Five routine handling treatments (shearing, crutching, drenching, dipping and drafting) were imposed on groups of 30 Merino wethers. Haematocrit and plasma cortisol were measured as an indication of the physiological stress response. Both parameters were significantly elevated after shearing...

  5. Behavioural and physiological consequences of capture for shearing of vicunas in Argentina

    Contributor(s):: Arzamendia, Y., Bonacic, C., Vila, B.

    Behavioural, physical and physiological responses of Argentinean vicunas to capture, handling and shearing were studied for the first time. The research was undertaken in a study area of 2414 ha with a mean density of 12-40 vicunas/km2. Captures were conducted on groups of wild vicunas that had...

  6. Preferences of sheep for different types of pen flooring

    Contributor(s):: Faerevik, G., Andersen, I. L., Boe, K. E.

    In countries where the climate makes it practical with indoor housing during cold periods of the year and access to straw is limited, e.g. Iceland and Norway, housing of sheep on slats or expanded metal floors is common practice. However, European regulations for organic farming require that all...

  7. Thermoregulatory behaviour of sheep housed in insulated and uninsulated buildings

    Contributor(s):: Boe, K.

    This study was made to investigate the thermoregulatory behaviour of sheep in confinement. In Experiment 1, two groups of 8 lambs in both an insulated (IN) and uninsulated (UN) house (total 32 animals) were studied; the durations of lying with and without body contact and standing were recorded...

  8. A breeding goal to improve the welfare of sheep

    Contributor(s):: Scobie, D. R., Bray, A. R., O'Connell, D.

    This paper examines the practical and welfare implications of breeding a polled sheep with a short tail, devoid of wool on the head, legs, belly and breech, which has been proposed as a breeding goal (Scobie et al., Proceedings of the New Zealand Society of Animimal Production 57 (1997) 84-87)....

  9. A review of mulesing and other methods to control flystrike (cutaneous myiasis) in sheep

    Contributor(s):: Phillips, C. J. C.

    Flystrike (cutaneous myiasis) in sheep has the potential to have a major impact on the welfare of significant numbers of sheep worldwide, but particularly in Australia. The main control method used in Australia, the mulesing operation to remove folds of skin from the hindquarters of the sheep, is...

  10. Selection for easier managed sheep

    Contributor(s):: Conington, J., Collins, J., Dwyer, C.

    Current alterations in the farm environment, such as a reduced number of farm workers, may mean that sheep genotypes that are highly dependent on man for nutritional and reproductive success will experience poorer welfare within that environment. In the past 30 years, average flock size has...

  11. The physiological impact of wool-harvesting procedures in vicunas ( Vicugna vicugna )

    Contributor(s):: Bonacic, C., Macdonald, D. W.

    A current programme of wildlife utilization in the Andean region involves the capture of wild vicunas, their shearing, transport and, in some cases, captive farming. The effects of these interventions on the physiology, and thus welfare, of wild vicunas are unknown. As a first step to quantifying...
