  1. The long-term impact of infant rearing background on the behavioural and physiological stress response of adult common marmosets (Callithrix jacchus)

    Contributor(s):: Ash, Hayley, Smith, Tessa E., Buchanan-Smith, Hannah M.

  2. Designing laboratory marmoset housing: What can we learn from urban marmosets?

    Contributor(s):: Duarte, Marina H. L., Goulart, Vinícius D. L. R., Young, Robert J.

    How to house animals in captivity, so as to maximise their level of well-being, is one of the greatest practical challenges facing animal welfare scientists. Laboratory animal housing can, necessarily, be very restrictive in terms of the facilities being offered to the animal inhabitants due to...

  3. The long-term impact of infant rearing background on the affective state of adult common marmosets (Callithrix jacchus)

    Contributor(s):: Ash, Hayley, Buchanan-Smith, Hannah M.

    Early life environment, including temporary family separation, can have a major influence on affective state. Using a battery of tests, the current study compared the performance of adult common marmosets (Callithrix jacchus), reared as infants under 3 different conditions: family-reared twins,...

  4. The long-term impact of infant rearing background on the affective state of adult common marmosets ( Callithrix jacchus)

    Contributor(s):: Ash, H., Buchanan-Smith, H. M.

    Early life environment, including temporary family separation, can have a major influence on affective state. Using a battery of tests, the current study compared the performance of adult common marmosets ( Callithrix jacchus), reared as infants under 3 different conditions: family-reared twins,...

  5. Effects of training on stress-related behavior of the common marmoset ( Callithrix jacchus ) in relation to coping with routine husbandry procedures. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Bassett, L., Buchanan-Smith, H. M., McKinley, J., Smith, T. E.

    Using positive reinforcement, 12 common marmosets (Callithrix jacchus) were trained to provide urine samples on request. The marmosets were exposed to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The non-human animals spent less time inactive poststressor as...

  6. Severe intragroup aggressions in captive common marmosets ( Callithrix jacchus )

    Contributor(s):: Filippis, B. de, Chiarotti, F., Vitale, A.

    Members of captive colonies of common marmosets (Callithrix jacchus), a small New World primate, can occasionally be victims of repeated, and potentially fatal, attacks by a family-mate. This study examined the records of a colony, looking for past instances of such aggressions. The aim was to...

  7. The development of an operant conditioning training program for New World primates at the Bronx Zoo. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Savastano, G., Hanson, A., McCann, C.

    This article described the development of an operant conditioning training programme for 17 species of New World primates at the Bronx Zoo, New York, USA. To apply less invasive techniques to husbandry protocols, the study introduced behaviours such as hand feeding, syringe feeding, targeting,...

  8. Training common marmosets ( Callithrix jacchus ) to cooperate during routine laboratory procedures: ease of training and time investment. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: McKinley, J., Buchanan-Smith, H. M., Bassett, L., Morris, K.

    The first author trained 12 laboratory-housed common marmosets (Callithrix jacchus) in pairs to assess the practicality of positive reinforcement training as a technique in the management of these nonhuman animals. Behaviours taught were target training to allow homecage weighing and providing...

  9. Training nonhuman primates to cooperate with scientific procedures in applied biomedical research. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Scott, L., Pearce, P., Fairhall, S., Muggleton, N., Smith, J.

    This report provides a brief overview of aspects of training nonhuman primates who have been, and continue to be, used in this laboratory. The research context involves applied behavioral studies in which animals are trained to perform complex operant behavioral sequences, often in their homecage...

  10. Food distribution effects on the behaviour of captive common marmosets, Callithrix jacchus

    Contributor(s):: Bjone, S. J., Price, I. R., McGreevy, P. D.

  11. Effects of positive interaction with caretakers on the behaviour of socially housed common marmosets ( Callithrix jacchus )

    Contributor(s):: Manciocco, A., Chiarotti, F., Vitale, A.

    Every aspect of the life of the captive non-human primates should be carefully attended to, as updated refinement concept recommends. Interaction with humans as environmental enrichment for these animals is believed to be of value, but it has been subject to little quantitative evaluation. This...

  12. Assessment of preference for grid-flooring and sawdust-flooring by captive-bred marmosets in free-standing cages

    Contributor(s):: Hardy, A., Windle, C. P., Baker, H. F., Ridley, R. M.

    Marmosets (Callithrix jacchus) in a captive breeding colony living in metal caging, with wooden shelves and perches, were assessed by video recording for the time spent on the floor of the cage when that floor was a wire grid above a sawdust-filled tray and when it had been changed to a...

  13. Exploiting flavour preferences of common marmosets to increase palatability of a dry pellet diet

    Contributor(s):: Caldwell, C. A., Watson, C. F. E., Morris, K. D.

    Although commercially available complete diets exist for common marmosets, the animals' consumption of these diets (available in dry pellet form) is typically very low. Increasing consumption of the pellet diet could have positive consequences for the welfare of the marmosets as the pellets are...

  14. A note on indoor and outdoor housing preferences of common marmosets ( Callithrix jacchus )

    Contributor(s):: Pines, M. K., Kaplan, G., Rogers, L. J.

    This study examined the preferences of six pairs of common marmosets (Callithrix jacchus) from the colony at the University of New England, Australia, between their home cage and either a large, enriched, indoor room or a smaller outdoor cage. When given free access to move between their home...

  15. Cage sizes for tamarins in the laboratory

    Contributor(s):: Prescott, M. J., Buchanan-Smith, H. M.

    Provision of adequate space for captive animals is essential for good welfare. It affects not only their behaviour but also determines whether there is sufficient room for appropriate environmental enrichment. Most importantly, appropriate cage size permits captive animals to be housed in...

  16. Factors affecting the successful pairing of unfamiliar common marmoset ( Callithrix jacchus ) females: preliminary results

    Contributor(s):: Majolo, B., Buchanan-Smith, H. M., Morris, K.

    Laboratory primates are often housed in same-sex pairs to avoid single-housing and when breeding is to be prevented. However, pair formation is not without risks, as fights and injuries may occur. No data are available on pair formation in female common marmosets (C. jacchus), a species used...

  17. Feeding gum arabic to New World monkeys: species differences and palatability

    Contributor(s):: Herron, S., Price, E., Wormell, D.

    Members of the New World primate genera Callithrix and Cebuella have specializations for eating plant exudates. Exudates are also an important component of the diets of many other callitrichid species in the wild, especially at times of nutritional stress. Gum arabic is fed daily to all marmosets...
