  6. Lying patterns of high producing healthy dairy cows after calving in commercial herds as affected by age, environmental conditions and production

    | Contributor(s):: Steensels, M., Bahr, C., Berckmans, D., Halachmi, I., Antler, A., Maltz, E.

    An animal expresses its physiological and well-being status by its behaviour. Changes in behaviour can be associated with health, production or well-being problems and therefore with the profitability of the farm. The objectives of the present study were to analyse lying patterns of healthy...

  7. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    | Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

    Veal calves in Europe are typically fed large quantities of milk replacer and small amounts of solid feed, a diet known to lead to the development of abnormal oral behaviours in these animals. These abnormal oral behaviours are thought to be an indication of frustration, chronic stress, and...

  8. Behavioral and physiological responses of guide dogs to a situation of emotional distress

    | Contributor(s):: Fallani, G., Prato Previde, E., Valsecchi, P.

    The aim of this study was to analyze the behavioral and physiological reactions of guide dogs in a distressing situation which promotes attachment behaviors towards their blind owners, and to compare such reactions with those of untrained or trainee dogs. The subjects were 57 adult Labrador and...

  9. Human-animal interaction, stress, and embryo production in Bos indicus embryo donors under tropical conditions

    | Contributor(s):: Macedo, G. G., Zuccari Neto, C. E. S., Abreu, U. G. P. de, Negrao, J. A., Costa e Silva, E. V. da

    This study investigated the effect of human-animal interaction (HAI) and the stress response on the quality of embryo production in superovulated Nelore (Bos indicus) cattle, under tropical conditions. Thirty-two females underwent a superovulation protocol for 5 days. Cortisol concentrations were...

  10. Relationships between puppy management practices and reported measures of success in guide dog training

    | Contributor(s):: Batt, L., Batt, M., Baguley, J., McGreevy, P.

    This study surveyed international guide dog organizations to compare their success rates with management practices. A questionnaire designed to identify the factors associated with international guide dog success was piloted with the cooperation of Guide Dogs NSW/ACT. The International Guide Dog...

  11. Effects of age, sex and social isolation on contrafreeloading in red junglefowl ( Gallus gallus ) and White Leghorn fowl

    | Contributor(s):: Lindqvist, C., Jensen, P.

    Contrafreeloading (CFL), i.e. choosing to work to obtain food over free food, has been studied in many different species. White Leghorn laying hens selected for high production have a lower extent of CFL compared to their wild ancestor, red junglefowl. We studied the effects of age, sex and...

  12. 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...

  13. Fear of novel and startling stimuli in domestic dogs

    | Contributor(s):: King, T., Hemsworth, P. H., Coleman, G. J.

    Dog aggression to humans is a serious problem and it appears that fear-induced aggression in dogs is often implicated. Furthermore, it has been suggested that novel and startling stimuli may trigger fear-induced aggression. The aim of the present study was to study some possible behavioural and...

  14. Describing the ideal Australian companion dog

    | Contributor(s):: King, T., Marston, L. C., Bennett, P. C.

    Dogs have had a long association with humans and are believed to be the first domesticated animal species. Many breeds of dog exist today which vary considerably in physical appearance and temperament. These differences have arisen primarily from selective pressures imposed by humans to create...

  15. A refinement and validation of the Monash Canine Personality Questionnaire (MCPQ)

    | Contributor(s):: Ley, J. M., Bennett, P. C., Coleman, G. J.

    The investigation of canine personality has failed to find strong agreement between studies as to its structure. The area has been hampered by a reliance on human personality models and by a tendency to limit the types of dogs used as subjects. These problems were recently addressed during the...

  16. Validation of an automatic system to detect position changes in puerperal sows

    | Contributor(s):: Mainau, E., Dalmau, A., Ruiz-de-la-Torre, J. L., Manteca, X.

    Piglet crushing by the sow is one of the main causes of piglet mortality during the first 48 h after birth. The frequency of position changes may be partially related to the pain caused by farrowing. The aim of this study was to develop and validate an automatic system to register position...

  17. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    | Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal ("low")) and two...
