  1. "What do animals mean to you?": naming and relating to nonhuman animals

    Contributor(s):: Sealey, A., Charles, N.

  2. A cage without a view increases stress and impairs cognitive performance in rats

    Contributor(s):: Harris, A. P., D'Eath, R. B., Healy, S. D.

    Single housing is believed to be chronically stressful and to have a negative impact on welfare and cognition in rats (Rattus norvegicus). However, single housing does not consistently evoke stress-like responses nor does it consistently impair cognitive performance. In an experiment in which all...

  3. A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins ( Saguinus labiatus )

    Contributor(s):: Owen, Y., Amory, J. R.

    Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or veterinary practices is accepted as a...

  4. A comparison of maltreated children and non-maltreated children on their experiences with animals - a Japanese study

    Contributor(s):: Yamazaki, S.

    Recently, studies in the United States, Canada, and Europe have shown that child abuse and animal abuse can coexist in the same household. The implications of these studies are that attention to animal abuse might lead to early detection of, and intervention in, child abuse. Although a promising...

  5. A comparison of positive reinforcement training techniques in owl and squirrel monkeys: time required to train to reliability

    Contributor(s):: Rogge, J., Sherenco, K., Malling, R., Thiele, E., Lambeth, S., Schapiro, S., Williams, L.

    Positive reinforcement training (PRT) techniques enhance the psychological well being of nonhuman primates by increasing the animal's control over his or her environment and desensitizing the animal to stressful stimuli. However, the literature on PRT in neotropical primates is limited. Here PRT...

  6. A comparison of the Monty Roberts technique with a conventional UK technique for initial training of riding horses

    Contributor(s):: Fowler, V., Kennedy, M., Marlin, D.

  7. A comparison of weaning techniques in farmed wapiti ( Cervus elaphus )

    Contributor(s):: Haigh, J. C., Stookey, J. M., Bowman, P., Waltz, C.

    A total of 21 wapiti calves, born between 24 May and 4 July were kept with their dams in a 5-ha paddock from 28 July to 28 August, after which they were moved to another field. On 5 September, they were weighed, divided into 2 groups (10 and 11 calves) and moved to a familiar paddock, adjacent to...

  8. A continuous recording approach to qualitative behaviour assessment in dairy buffaloes ( Bubalus bubalis)

    Contributor(s):: Napolitano, F., Rosa, G. de, Serrapica, M., Braghieri, A.

    In order to develop a method suitable for a continuous qualitative evaluation of animal behaviour while it changes during the observation period, two recently described techniques, the Qualitative Behaviour Assessment (QBA) and the Temporal Dominant Behavioural Expression (TDBE), derived by the...

  9. 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...

  10. A method for assessing the relative sociability of individuals within groups: an example with grazing sheep

    Contributor(s):: Sibbald, A. M., Elston, D. A., Smith, D. J. F., Erhard, H. W.

    We describe a method for quantifying relative sociability within a group of animals, which is defined as the tendency to be close to others within the group and based on the identification of nearest neighbours. The method is suitable for groups of animals in which all individuals are visible and...

  11. A method for quantification of jaw movements suitable for use on free-ranging cattle

    Contributor(s):: Matsui, K., Okubo, T.

    A data-logging system for the simultaneous measurement of the J-J interval (the interval between two successive jaw movements), the number of jaw movements and the number of pauses between jaw movements longer than 3 s was developed and tested in free-ranging cattle. The system, which consists of...

  12. A method for the economic valuation of animal welfare benefits using a single welfare score

    Contributor(s):: Bennett, R., Kehlbacher, A., Balcombe, K.

  13. A modified HET-CAM approach for biocompatibility testing of medical devices

    Contributor(s):: Eder, C., Falkner, E., Mickel, M., Chiari-Grisar, C., Appl, H., Schoffl, H., Nehrer, S., Losert, U. M.

    The implantation of new biomedical devices into living animals without any previous toxicity or biocompatibility evaluation is possible under current legislation. The HET-CAM (Hen Egg Test-Chorionallantoic Membrane) test offers a partially immunodeficient, borderline in vitro/in vivo test system...

  14. 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...

  15. A new technique for monitoring the detailed behaviour of terrestrial animals: a case study with the domestic cat

    Contributor(s):: Watanabe, S., Izawa, M., Kato, A., Ropert-Coudert, Y., Naito, Y.

    For many animal species that are difficult to access, the behaviour of free-ranging individuals cannot be assessed by direct observation. In order to remedy this, we developed a new technique using a motion detector (acceleration data-logger) for monitoring the activity and behaviour of...

  16. A non-intrusive method of assessing plumage condition in commercial flocks of laying hens

    Contributor(s):: Bright, A., Jones, T. A., Dawkins, M. S.

  17. A non-invasive telemetry system for obtaining heart rate from free-ranging swine

    Contributor(s):: Friend, T. H., Dellmeier, G. R., Stuart, J. L.

    A vest made of four-way stretch heavy duty nylon spandex was developed to hold telemetry equipment and permit the use of body surface electrodes for obtaining heart rate data on free-ranging or confined domestic pigs. The vest was laced on sows with a reinforcing 7.5 cm elastic belt encircling...

  18. A note on a modification of the spread of participation index allowing for unequal zones

    Contributor(s):: Plowman, A. B.

    The spread of participation index (SPI) is used to indicate the extent of enclosure utilisation by captive animals. The established method of determining the SPI requires the division of the enclosure into equal sized zones. This method has several practical and theoretical difficulties, most...

  19. A note on silent ovulation identified by using radiotelemetry for estrous detection

    Contributor(s):: Shipka, M. P.

    The occurrence of silent ovulation in high-producing, postpartum Holstein cows was examined. 19 multiparous cows were fitted with transmitters (HeatwatchReg.) for radiotelemetry and examined using a visual oestrus detection routine for 1/2 h twice daily, on day 10 post partum. Blood samples were...

  20. A note on the influence of starting position, time of testing and test order on the backtest in pigs

    Contributor(s):: Erp-van der Kooij, E. van, Kuijpers, A. H., Eerdenburg, F. J. C. M. van, Tielen, M. J. M.

    The backtest determines the coping behaviour of a piglet in a standardized stress situation, which might be a measure for the coping style of that animal. Backtest results are related to other parameters such as immune responses and production. In this study, the backtest was standardized and it...
