Development of a novel paradigm for the measurement of olfactory discrimination in dogs ( Canis familiaris): a pilot study
Contributor(s):: Salvin, H. E., McGrath, C., McGreevy, P. D., Valenzuela, M. J.
Olfactory dysfunction in older human beings has been shown to be associated with an increased risk of cognitive decline, yet age-related changes in olfactory behavior have received little attention in the dog model of human aging. We developed an odor habituation and fine odor discrimination...
Litterbox size preference in domestic cats ( Felis catus)
Contributor(s):: Guy, N. C., Hopson, M., Vanderstichel, R.
The objective of this study was to evaluate the response of healthy housebound domestic cats to the simultaneous provision of 2 litterboxes of differing sizes by recording the average daily frequency of urination and defecation in each box. Forty-three households with 74 privately owned cats were...
Human-animal interactions and animal welfare in conventionally and pen-housed rats
Contributor(s):: Augustsson, H., Lindberg, L., Hoglund, A. U., Dahlborn, K.
The main aim of the present study was to explore the significance of large group/greater pen housing (PH) versus standard Makrolon caging (ST) in three behaviour tests related to human-animal interactions in the adult male laboratory rat. The rats' perception of human interaction was tested in...

Influence of cage enrichment on aggressive behaviour and physiological parameters in male mice
Contributor(s):: Loo, P. L. P. van, Kruitwagen, C. L. J. J., Koolhaas, J. M., Weerd, H. A. van de, Zutphen, L. F. M. van, Baumans, V.
From welfare perspective group, housing of mice is preferred over individual housing. Group housing of male laboratory mice, however, often leads to problems due to excessive aggressive behaviour. In our search for management and housing modifications to decrease aggression in group-housed male...
Preliminary study of the development of the Flehmen response in Equus caballus
Contributor(s):: Weeks, J. W., Crowell-Davis, S. L., Heusner, G.
The flehmen response is commonly seen in most ungulates as well as in several other species (e.g. felids). The behaviour is most often thought to be part of the sexual behavioural repertoire of males. One reigning hypothesis suggests that this behaviour allows the male to determine the oestrous...
Urinary behavior of female domestic dogs ( Canis familiaris ): influence of reproductive status, location, and age
Contributor(s):: Wirant, S. C., McGuire, B.
The urinary behaviour of adult domestic dogs (Canis familiaris) is sexually dimorphic with respect to the posture (males lift a leg and females squat), frequency of urination (males urinate more frequently than females), and tendency to direct urine at specific objects in the environment (males...
Urine marking by free-ranging dogs ( Canis familiaris ) in relation to sex, season, place and posture
Contributor(s):: Pal, S. K.
Carnivores use various scent-marking methods. Observations on the scent marking by urination of 16 free-ranging dogs from two neighbouring groups were recorded in the town of Katwa, West Bengal, India. The frequency of urine marking was higher in males than in females. The seasonal mean...
Diurnal distribution of dairy cow defecation and urination
Contributor(s):: Aland, A., Lidfors, L., Ekesbo, I.
This study investigated the diurnal distribution of urination and defaecation in tied dairy cows with reference to management routines and milk yield/feeding intensity. A total of 16 lactating cows and 4 heifers were videotaped during 9 consecutive 24-h periods. The cows had a mean of 16.1...
Evidence that zoo visitors influence HPA activity in spider monkeys ( Ateles geoffroyii rufiventris ). (Special issue: Primates in zoos)
Contributor(s):: Davis, N., Schaffner, C. M., Smith, T. E.
There has been conflicting evidence about the impact of visitors on zoo animals. The present study was designed to increase understanding of visitor effect by assessing the relationship between visitor numbers and activity in the hypothalamic-pituitary-adrenal (HPA) axis. An enzyme-immunoassay...
Feline urine spraying
Contributor(s):: Dehasse, J.
10% of all cats spray in adulthood. The sequence of urine spraying and its triggering stimuli were analysed and its pharmacological treatment is summarized. Clomipramine (AnafranilReg.) was tested on 26 cats (5 mg once a day). The results showed clomipramine is responsible for a reduction of...
Ability of goats and calves to distinguish between conspecific urine samples using olfaction
Contributor(s):: Baldwin, B. A.
Goats and calves were trained, using an operant conditioning method, to discriminate between odours from pairs of urine samples collected from two different individuals of their own species. In the discrimination task the animals faced two response panels, and a tube adjacent to one panel emitted...

Behavioural responses of cattle to the odours of blood and urine from conspecifics and to the odour of faeces from carnivores
Contributor(s):: Terlouw, E. M. C., Boissy, A., Blinet, P.
Before experimentation, 12 heifers were trained during 15 days to walk through a corridor for food. In the middle of the corridor, at either side, 2 ventilating odour dispensers were fixed behind perforated screens. The odours of urine from non-stressed and stressed conspecifics and of blood were...
Preliminary observations on the urinary behaviour of female Jack Russell Terriers in relation to stage of the oestrous cycle, location, and age
Contributor(s):: Wirant, S. C., Halvorsen, K. T., McGuire, B.
In female canids, including domestic dogs (Canis familiaris), scent-marking with urine is thought to convey information on reproductive state, yet little is known about how urinary behaviour changes across specific stages of the oestrous cycle. We measured urinary behaviour (proportion of...
Stereotypies and cortisol secretion in heifers subjected to tethering
Contributor(s):: Redbo, I.
The aims of this study were to assess the effect of tethering on environmentally induced stereotypies and urine cortisol concentrations in Swedish Red and White heifers, and to analyse a possible relationship between the performance of stereotypies and cortisol concentration. Three groups of...

To swim or not to swim: an interpretation of farmed mink's motivation for a water bath
Contributor(s):: Vinke, C. M., Hansen, S. W., Mononen, J., Korhonen, H., Cooper, J. J., Mohaibes, M., Bakken, M., Spruijt, B. M.
How an animal's behavioural needs can be met is a pivotal issue in the assessment of welfare for captive animals. The value of swimming water for farmed mink is an example of how scientific and societal questions relating to animal welfare can be answered. A number of studies have addressed the...

Behavioral responses of bulls kept under artificial breeding conditions to compounds presented for olfaction, taste or with topical nasal application
Contributor(s):: Presicce, G. A., Brockett, C. C., Cheng, T., Foote, R. H., Rivard, G. F., Klemm, W. R.
The object of this study was to test practical ways of influencing behaviour of bulls used for artificial insemination. Dairy bulls that were sexually active with regular semen collections were compared with sexually inactive bulls housed elsewhere, after being sampled in artificial breeding as...
