  1. The behavioural effects of supplementing diets with synthetic and naturally sourced astaxanthin in an ornamental fish (Puntius titteya)

    Contributor(s):: Eaton, Lewis, Clezy, Kristian, Snellgrove, Donna, Sloman, Katherine

    Carotenoids are routinely incorporated into ornamental fish diets with the aim of enhancing companion fish colouration which may concomitantly affect fish behaviour. Previously, colour enhancement has typically been achieved using synthetic carotenoids, however, there is now growing public demand...

  2. Investigating the role of coat colour, age, sex, and breed on outcomes for dogs at two animal shelters in the United States

    Contributor(s):: Svoboda, H. J., Hoffman, C. L.

    The popular press frequently reports that coat colour bias negatively impacts shelter adoption rates for black domestic dogs. This phenomenon, commonly called 'black dog syndrome' (BDS), reportedly increases the likelihood of euthanasia for black dogs and negatively affects the length of black...

  3. An evaluation of the role the Internet site Petfinder plays in cat adoptions

    Contributor(s):: Workman, M. K., Hoffman, C. L.

    To better understand factors contributing to cat adoptions, this study was used to explore a possible association between an adoptable cat's popularity on Petfinder and the cat's length of availability for adoption at a managed-intake nonhuman animal shelter. This study was also used to examine...

  4. Age, breed designation, coat color, and coat pattern influenced the length of stay of cats at a no-kill shelter

    Contributor(s):: Brown, W. P., Morgan, K. T.

    Adoption records from the Tompkins County Society for the Prevention of Cruelty to Animals, an open-admission, no-kill shelter in New York State, were examined to determine if various physical attributes influenced the length of stay (LOS) of cats and kittens. Similar reports from other no-kill...

  5. Effects of phenotypic characteristics on the length of stay of dogs at two no kill animal shelters

    Contributor(s):: Brown, W. P., Davidson, J. P., Zuefle, M. E.

    Adoption records from 2 no kill shelters in New York State were examined to determine how age, sex, size, breed group, and coat color influenced the length of stay (LOS) of dogs at these shelters. Young puppies had the shortest length of stay; LOS among dogs increased linearly as age increased....

  6. Factors relevant to adoption of cats in an animal shelter

    Contributor(s):: Fantuzzi, J. M., Miller, K. A., Weiss, E.

    This study performed a multifactor analysis of the effects of the provision of toys, cage location, and cat characteristics (activity level, age, sex, and coat color) on 111 cats available for adoption in a nonhuman animal shelter. The analysis revealed a greater adopter viewing of cats housed at...

  7. The role of coat color and ear shape on the perception of personality in dogs

    Contributor(s):: Fratkin, J. L., Baker, S. C.

  8. Human perceptions of coat color as an indicator of domestic cat personality

    | Contributor(s):: Delgado, M. M., Munera, J. D., Reevy, G. M.

    Associations between mammalian coat color and behavior have been investigated in a number of species, most notably the study of silver foxes by the Institute of Cytology and Genetics at the Russian Academy of Sciences. However, the few studies conducted regarding a potential relation between...

  9. Dairy cows prefer shade that offers greater protection against solar radiation in summer: shade use, behaviour, and body temperature

    | Contributor(s):: Schutz, K. E., Rogers, A. R., Cox, N. R., Tucker, C. B.

    There is considerable evidence that shade is a valuable resource for cattle in summer, but less is known about the important design features of effective shade. The aim of this experiment was to investigate if lactating dairy cows have a preference for shade that offers greater protection against...

  10. Use of pelage pigmentation in the recognition of mothers in a group by 2- to 4-month-old domestic goat kids

    | Contributor(s):: Ruiz-Miranda, C. R.

    This study investigated whether domestic goat kids use pelage pigmentation as an aid to recognize their mothers within a group of 30 does. Observations on the use of auditory cues were also made. The identification errors made by 2- to 4- month-old kids were biased toward does of the same colour...

  11. Domestication, selection, behaviour and welfare of animals - genetic mechanisms for rapid responses

    | Contributor(s):: Jensen, P.

    Increased production has been the major goal of animal breeding for many decades, and the correlated side-effects have grown to become a major issue in animal welfare. In this paper, the main genetic mechanisms in which such side-effects may occur are reviewed with examples from our own research...

  12. Factors affecting time to adoption of dogs re-homed by a charity in the UK

    | Contributor(s):: Diesel, G., Smith, H., Pfeiffer, D. U.

    The objective of this retrospective cohort study was to determine the factors affecting the time until adoption of dogs re-homed by Dogs Trust, a UK charity. There were 13,338 records included in the study, representing 11,663 dogs. Data were extracted from the Dogs Trust's database between...
