  1. "Puppy mill" bill: intentions, good; implementation, another story

    Contributor(s):: DiVita, L. J.

  2. 'Libido' in the larger farm animals: a review

    Contributor(s):: Wodzicka-Tomaszewska, M., Kilgour, R., Ryan, M.

    The term 'libido', first used by Freud to refer to the force by which the sexual instinct is represented in the mind, has become more and more used to refer to some aspects of sexual behaviour in large domestic animals. From being a wide, rather imprecise term, it has come to be defined in a...

  3. A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages

    Contributor(s):: Chu, L. R., Garner, J. P., Mench, J. A.

    Despite their gregarious nature, rabbits used for research are often housed individually due to concerns about aggression and disease transmission. However, conventional laboratory cages restrict movement, and rabbits housed singly in these cages often perform abnormal behaviours, an indication...

  4. A behavioural study of scrapie-affected sheep

    Contributor(s):: Healy, A. M., Hanlon, A. J., Weavers, E., Collins, J. D., Doherty, M. L.

    The behaviour of 12 sheep, suspected of having scrapie, and 12 clinically normal animals from the Irish Republic was observed over a 6-day period [date not given]. Confirmation of the true disease status of the animals was made at postmortem using both histopathological and immunocytochemical...

  5. A brief note on the effects of the removal of individuals on social behaviour in a captive group of campbell's monkeys ( Cercopithecus campbelli campbelli ): a case study

    Contributor(s):: Lemasson, A., Gautier, J. P., Hausberger, M.

    We investigated the social effects of the removal of two adult females, including the founder of a matriline, in a group of captive Campbell's monkeys (Cercopithecus campbelli campbelli). Their social behaviour was recorded 1 month before, 1 week after, and 7 months after the removal of the...

  6. A brief report on intraspecies aggressive biting in a goat herd

    | Contributor(s):: Tolu, C., Savas, T.

    This study aimed at analysing the effects of age, horn and places on biting and butting as intraspecies aggressive activities. Seventy-two Turkish Saanen goats were used as animal material and 22,686 aggressive behaviours were recorded in different places from a total of 118 h direct observation....

  7. A comparative study of the influence of social housing conditions on the behaviour of captive tigers ( Panthera tigris )

    | Contributor(s):: Rouck, M. de, Kitchener, A. C., Law, G., Nelissen, M.

    Nowadays, zoos are increasingly concerned with animal welfare as public expectations and knowledge of the needs of captive animals increases. Although many zoos try to provide all sorts of enrichment for their big cats, the importance of social enrichment is not yet fully understood. This study...

  8. A comparison of dog-dog and dog-human play behaviour

    | Contributor(s):: Rooney, N. J., Bradshaw, J. W. S., Robinson, I. H.

    In an observational study of dogs being walked by their owners (402), dogs which were walked together, and had opportunities to play with one another, played with their owners with the same frequency as dogs being walked alone. This finding was supported by a questionnaire survey of 2585 dog...

  9. A comparison of social and environmental enrichment methods for laboratory housed dogs

    | Contributor(s):: Hubrecht, R. C.

    48 Beagles in 4 equal groups: (controls; opportunities for social contacts with conspecifics; given 30 s/day of intensive handling; and provided with 3 different toys/chews permanently suspended in the pen (Rawhide, Gumabone chew and a piece of plastic tubing)) were observed for a total of 432 h....

  10. A comparison of the activity budgets of wild and captive Sulawesi crested black macaques ( Macaca nigra )

    | Contributor(s):: Melfi, V. A., Feistner, A. T. C.

    One aim of environmental enrichment techniques is to replicate 'wild-like' behaviour in captivity. In this study, three captive troops of Sulawesi crested black macaques (M. nigra) in Chester, Jersey and Marwell Zoos, UK were each observed for 100 h in large naturalistic enclosures In May and...

  11. A comparison of the effects of simple versus complex environmental enrichment on the behaviour of group-housed, subadult rhesus macaques

    | Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Suarez, S. A., Porter, L. M.

  12. A critically appraised topic (CAT) to compare the effects of single and multi-cat housing on physiological and behavioural measures of stress in domestic cats in confined environments

    Full-text: Available

    | Contributor(s):: Lauren R Finka, Sarah LH Ellis, Jenny Stavisky

    BackgroundDomestic cats have evolved from solitary, asocial predators and whilst they may display social behaviours, they can still exist as solitary survivors. Over-population and relinquishment of pet cats are ubiquitous problems worldwide, and rehoming centres (also known as rescues/ shelters)...

  13. A developmental approach to dog's sociality

    | Contributor(s):: Mogi, K., Nagasawa, M., Kikusui, T.

    A special relationship between human and dog is considered to be established by dog's characteristic social skill and cognitive ability, based on adequate emotional and affiliative behavior. It has been emphasized that puppy's experience in its developing period is prerequisite for dog's...

  15. A fresh look at the wolf-pack theory of companion-animal dog social behavior

    | Contributor(s):: Kerkhove, W. van

    A popular perspective on the social behavior of dogs in multiple-dog households sees the dogs' behavior as reflecting the sociobiological laws of the rigidly structured dominance hierarchy that has been described for wolf packs. This view suggests that aggression problems among dogs are natural...

  16. A general reaction pattern across situations in prepubertal gilts

    | Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S.

    56 prepubertal crossbred Landrace/Yorkshire gilts were subjected to a Food Competition Test, an Open Field Test, a Human Test and a Social Test. The undisturbed behaviour was video recorded in the home pen before the tests were performed. Factor analysis on open field data identified 5 factors,...

    To quantify the combined effect of housing conditions and environmental enrichment on the behaviour and performance of pigs, a meta-analysis was performed using information from 45 experiments in 42 published manuscripts. Multiple regression models were applied to evaluate the effects of space...

  19. 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...

    | Contributor(s):: Galindo, F., Broom, D. M., Jackson, P. G. G.

    Possible relationships between social behaviour, individual time budgets and the incidence of lameness were investigated in 40 dairy cows. The incidence of lameness in the group of cows was 42
