  1. Motivation of sheep to eat clover offered in a short-term closed economy test

    Contributor(s):: Champion, R. A., Lagstrom, N. A., Rook, A. J.

    Six sheep were trained, over a period of 11 weeks, to work for a reward of freshly cut clover by walking along a variable length, U-shaped race. Training included habituation to the presence of an observer and to isolation from conspecifics. Following training, motivation to eat clover was tested...

  2. Protecting egg prey from Carrion Crows: the potential of aversive conditioning

    Contributor(s):: Cox, R., Baker, S. E., Macdonald, D. W., Berdoy, M.

    Carrion Crows, Corvus corone, are held responsible for taking the eggs and chicks of many bird species. In areas of conservation significance, intervention may be required. Traditionally, managers have attempted to control predation by killing predators, but this may not be the most effective or...

  3. Rapid shaping of behaviour associated with high urinary cortisol in domestic dogs

    Contributor(s):: Blackwell, E. J., Bodnariu, A., Tyson, J., Bradshaw, J. W. S., Casey, R. A.

    The occurrence of stress has widely been associated with impairments in learning abilities in animals, although the influence of stress appears to differ with the complexity of tasks. Previous research has suggested that some domestic dogs exhibit both physiological (elevated cortisol) and...

  4. Spatial-temporal arrangements of supplementation to modify selection of feeding sites by sheep

    Contributor(s):: Distel, R. A., Soca, P. M., Demment, M. W., Laca, E. A.

    Undesirable grazing distribution results in land degradation and inefficient forage utilization. Rewards like food supplements have been commonly provided at predictable times and locations in the less preferred areas in order to improve grazing distribution. The problem with this approach is the...

  5. The use of positive reinforcement training to reduce stereotypic behavior in rhesus macaques

    Contributor(s):: Coleman, K., Maier, A.

    Stereotypic behavior is a pervasive problem for captive monkeys and other animals. Once this behavior pattern has started, it can be difficult to alleviate. We tested whether or not using positive reinforcement training (PRT) can reduce this undesired behavior. Subjects for this study were 11...

  6. Use of a conditioning technique to reduce stress associated with repeated intra-peritoneal injections in laboratory rats

    Contributor(s):: Cloutier, S., Newberry, R. C.

    We hypothesized that using classical conditioning to pair a stressful procedure such as injection with a rewarding experience decreases the stress associated with repeated exposure to this procedure. We investigated the effectiveness of pairing repeated intra-peritoneal injections with a positive...

  7. A model to quantify the anticipatory response in cats

    Contributor(s):: Tami, G., Martorell, A., Torre, C., Compagnucci, M., Manteca, X.

    The aim of this paper was to develop a protocol to study the anticipatory response in cats as a measure of welfare. Seven experimental cats were trained in a classical conditioning paradigm to associate a sound with food arrival, while sound and food were presented without contingency in four...

  8. Effect of positive reinforcement training on physiological and behavioural stress responses in the hamadryas baboon ( Papio hamadryas )

    Contributor(s):: O'Brien, J. K., Heffernan, S., Thomson, P. C., McGreevy, P. D.

    Behavioural and salivary cortisol responses were measured in hamadryas baboons (Papio hamadryas) (n=5) undergoing positive reinforcement training (PRT). Compliance was assessed by collecting behavioural data on desirable and undesirable responses during each training session (33-46 training...

  9. Operant animal welfare: productive approaches and persistent difficulties

    Contributor(s):: Patterson-Kane, E. G., Pittman, M., Pajor, E. A.

    Operant procedures occupy a prominent role within animal welfare science because they provide information about the strength of animals' preferences. It is assumed that strongly motivated choices commonly indicate conditions necessary for uncompromised welfare. A review of the literature shows...

  10. Post-release survival of hand-reared pipistrelle bats ( Pipistrellus spp)

    Contributor(s):: Kelly, A., Goodwin, S., Grogan, A., Mathews, F.

    There is very little known about the post-release survival of hand-reared pipistrelle bats (Pipistrellus spp). We radio-tracked 12 pipistrelle bats, hand-reared and released under three different protocols: (i) limited pre-release flight training and over-wintering (n=5); (ii) prolonged...

  11. Managing separation anxiety: an evidence-based approach
