  1. "Nobody Wants to Eat Them Alive:" Ethical Dilemmas and Dual Media Narratives on Domestic Rabbits as Pets and Commodity

    Contributor(s):: Gayane F. Torosyan, Brian Lowe

    Using semiotic analysis, this study explores changes occurring in the societal perception of rabbits as farm animals as juxtaposed to their increasing popularity as domestic companions. This study is based on a preliminary hypothesis that rabbits are increasingly perceived and portrayed in media...

  2. "Poison-shyness" and "bait-shyness" developed by wild rats ( Rattus rattus L.). I. Methods for eliminating "shyness" caused by barium carbonate poisoning

    Contributor(s):: Naheed, G., Khan, J. A.

    Colonies of wild rats, were offered the choice between two baits-cereal grains, flours, mixtures, oily and sweet cereals, and also grain flour. The rats were poisoned in the preferred baits with barium carbonate (10 mg/g food; 20 mg/g food in oily baits) and then presented with the same choice of...

    2015 Animal Ethics Seminar

    A seminar for members of Animal Ethics Committees and their Executive Officers, and animal researchers, is to be held at the Australian Catholic University, North Sydney, on 29 September 2015. The...

  4. 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...

  5. A cautionary note regarding the use of nutritional L-tryptophan to alter aversion-related behaviour in mice

    Contributor(s):: Janczak, A. M., Bakken, M., Braastad, B. O.

    Nutritional L-tryptophan is reported to have positive effects on the behaviour of several farm animals. The present experiment describes some effects of nutritional L-tryptophan on the aversion-related behaviour of male mice selected for high litter size. The behavioural effects of L-tryptophan...

  6. A comparative assessment of potential conditioned taste aversion agents for vertebrate management

    Contributor(s):: Gill, E. L., Whiterow, A., Cowan, D. P.

    The ability of two potentially safe compounds, cinnamamide (160 mg/kg) and thiabendazole (100 and 200 mg/kg) to generate a conditioned taste aversion (CTA) in laboratory Rattus norvegicus to a novel food was assessed and compared to that of 17 alpha ethinyl oestradiol (4 mg/kg). All compounds...

  7. A comparison of a manual and an automated behavioural analysis method for assessing post-operative pain in mice

    Contributor(s):: Miller, A. L., Flecknell, P. A., Leach, M. C., Roughan, J. V.

    Current methods of identifying and analysing behavioural signs of pain in mice are highly time consuming and labour intensive. HomeCageScan (HCS) is an automated analysis system that may offer an alternative to manual scoring. Thirty-two male mice undergoing vasectomy were filmed before and at 1...

  8. A mouse is not just a mouse

    Contributor(s):: Sluyter, F., Oortmerssen, G. A. van

    In this review, we describe the existence and consequences of subspecific and individual variation in the genetic make-up of house mice. The purpose is to illustrate forms of variation that are often neglected in discussions about animal care and experimental design. Different inbred mouse...

  9. A note on behavioural response to a novel arena in lactating mice highly selected for litter size

    Contributor(s):: Rauw, W. M.

    In an earlier experiment it was found that adult non-reproductive virgin female mice from a line selected for 91 generations for high litter size at birth (S-line; about 20 pups per litter) showed similar or more locomotion activity in four novelty behavioural tests (open-field, runway, maze and...

  10. A note on behavioural responses of farm animals to ultrasound

    Contributor(s):: Algers, B.

    Horses, cattle, swine, sheep and poultry all reacted to ultrasound from a device used to clear rats from buildings. Most animals were drawn towards the sound at first and then turned away and kept their ears pointing away from the sound. Poultry showed the least reaction. The device is considered...

  11. A note on comparative enclosure facility usage by wild and captive-born capybaras ( Hydrochaerus hydrochaeris )

    Contributor(s):: Nogueira, S. S. C., Bernardi, L. G., Nogueira Filho, S. L. G.

    This study compared the use of the enclosure facilities (sheltered area, water-tank and exercise area) by wild versus captive-born capybaras. A total of 44 adult capybaras were kept in eight groups: four groups of animals born in the wild and caught as adults and four groups of those born and...

  12. A note on the cecotrophy behavior in capybara ( Hydrochaeris hydrochaeris )

    Contributor(s):: Mendes, A., Nogueira, S. S. da C., Lavorenti, A., Nogueira-Filho, S. L. G.

    Six adult capybaras (56 kg) were placed in individual pens and observed for 96 serial hours. During this period a behavioural pattern believed to consist of caecotrophy was observed 243 times. Animals sat on their hind limbs, stretched either limb out, bent over driving their heads in the...

  13. A Quantitative Prioritisation of Human and Domestic Animal Pathogens in Europe

    Full-text: Available

    Contributor(s):: K. Marie McIntyre, Christian Setzkorn, Philip J. Hepworth, Serge Morand, Andrew P. Morse, Matthew Baylis

    Disease or pathogen risk prioritisations aid understanding of infectious agent impact within surveillance or mitigation and biosecurity work, but take significant development. Previous work has shown the H-(Hirsch-)index as an alternative proxy. We present a weighted risk analysis describing...

  14. A rat-resistant artificial nest box for cavity-nesting birds

    Contributor(s):: Pitt, W. C., Driscoll, L. C., VanderWerf, E. A.

  15. A review of the behavioral and neurochemical consequences of early weaning in rodents. (Special Issue: Early Weaning.)

    Contributor(s):: Kikusui, T., Nakamura, K., Mori, Y.

    In mammals, mother-infant bonding is based on the dependence of the infant on the mother for sustenance, i.e., the infant suckles milk, but also involving a need for physical contact. Weaning is one of the most important events that occur in developing animals and the timing of natural weaning is...

  16. A survey assessment of the incidence of fur-chewing in commercial chinchilla ( Chinchilla lanigera ) farms

    Contributor(s):: Ponzio, M. F., Busso, J. M., Ruiz, R. D., Cuneo, F. M. de

    Chinchilla lanigera intensive breeding programmes are affected by an abnormal repetitive behaviour called 'fur-chewing', yet the aetiology is still unknown and little scientific work has been published on this condition. Recent studies have supported the idea that fur-chewing is a stress-related...

  17. A survey of pet- and non-pet-owning Swedish adolescents: demographic differences and health issues

    Contributor(s):: Mullersdorf, M., Granstrom, F., Tillgren, P.

  18. A targeted approach to developing environmental enrichment for two strains of laboratory mice

    Contributor(s):: Nicol, C. J., Brocklebank, S., Mendl, M., Sherwin, C. M.

    Previous studies on environmental enrichment have generally placed a purported enrichment in the cage and observed changes in behavioural and physiological indicators of welfare. However, many of these 'enrichments' are not purposely designed, or appear to be designed with anthropomorphic or...

  19. Acute effects of cage cleaning at different frequencies on laboratory rat behaviour and welfare

    Contributor(s):: Burn, C. C., Peters, A., Mason, G. J.

  20. All a mother's fault? Transmission of stereotypy in striped mice Rhabdomys

    Contributor(s):: Jones, M., Lierop, M. van, Pillay, N.

    Environmentally induced stereotypy is the most common abnormal behaviour in captive animals. However, not all animals housed in identically impoverished environments develop stereotypy, possibly because of differences in genetic predisposition. To investigate the transmission of stereotypy in...
