  1. The sex of the offspring affects the lamb and ewe responses to abrupt weaning

    Contributor(s):: Freitas-de-Melo, A., Ungerfeld, R.

    Female lambs have a stronger attachment with their mothers and show a greater susceptibility to stressors than male lambs. Male lambs grow faster than female lambs do, achieving a greater nutritional independence from their mothers. Our hypothesis was that female lambs and their mothers are more...

  2. Can access to an automated grooming brush and/or a mirror reduce stress of dairy cows kept in social isolation?

    Contributor(s):: Mandel, Roi, Wenker, Margret L., van Reenen, Kees, Keil, Nina M., Hillmann, Edna

    In dairy farming, social isolation of cattle is commonly practiced for husbandry procedures such as artificial insemination, claw trimming and at times, for provision of medical treatment. When isolated, cows express physiological and behavioural signs of stress, such as elevated heart rate,...

  3. Separation-related behaviour indicates the effect of functional breed selection in dogs (Canis familiaris)

    Contributor(s):: Pongrácz, Péter, Gómez, Sara Alvarez, Lenkei, Rita

    The domestication of dogs resulted in several fundamental behavioural changes as compared to their closest wild living relative, the wolf. While these characteristics are considered to be fairly robust across dogs, dog breeds themselves manifest apparently strong behavioural differences. Thus far...

  4. Behavioral and cortisol responses of adult marmoset monkeys (Callithrix penicillata) to different home-cage social disruption intervals

    Contributor(s):: Duarte, Renata B., Maior, Rafael S., Barros, Marilia

    Social separation is an increasingly used strategy to experimentally assess psychogenic stress in nonhuman primates, yet it is also inherently required for captive management. Surprisingly, little is known on the effects of an individual left alone in a highly familiar place, compared to...

  5. The effects of green odour on domestic dogs: A pilot study

    Contributor(s):: Carlone, Beatrice, Gazzano, Angelo, Gutiérrez, Jara, Sighieri, Claudio, Mariti, Chiara

    Green odour (a mixture of cis-3-hexenol and trans-2-hexenal), similar to cut grass, has been demonstrated to appease subjects of various species (rats, cattle, humans etc.) subjected to different stressful stimuli. The aim of this study was to investigate whether green odour has a calming effect...

  6. Fear vs. frustration - Possible factors behind canine separation related behaviour

    Contributor(s):: Lenkei, R., Alvarez Gomez, S., Pongracz, P.

  7. Separation, Confinement, or Noises: What Is Scaring That Dog?

    Contributor(s):: Ballantyne, K. C.

  8. Brazilian Citizens: Expectations Regarding Dairy Cattle Welfare and Awareness of Contentious Practices

    Contributor(s):: Clarissa S. Cardoso, Marina A.G. von Keyserlingk, Marie Jose Hotzel

    The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling...

  9. A Parental Perspective: The Role of Companion Animals for Children During Separation and Divorce

    Contributor(s):: Jessica Michel

    Children grow up in interdependent family systems, where transitions affect all members. A prevalent transition in Australian families is divorce. When divorce occurs children are exposed to significant risk factors that have the potential of affecting many developmental outcomes. However,...

    Contributor(s):: Giulia Bampi

    Atualmente é crescente o número de animais de companhia acometidos pela síndorme de ansiedade de separação (SAS), condição relacionada a distúrbios no vínculo humano-animal que levam a uma hipervinculação...

  11. “Not just a dog”: An attachment perspective on relationships with assistance dogs

    Contributor(s):: Kwong, Marilyn, Bartholomew, Kim

    We explored individuals' relationships with an assistance dog from an attachment-theory perspective. We used both inductive and deductive thematic methods to analyze semi-structured interviews with 25 participants who had lost an assistance dog to retirement or death. Analyses revealed attachment...

  12. Public attitudes towards grief in animals

    Contributor(s):: McGrath, N., Walker, J., Nilsson, D., Phillips, C.

    Animals under human management are often separated from conspecifics, which may lead to behaviour indicative of separation distress or grief. For the purposes of this paper, grief is considered as a biological response to separation, indicated by a bi-phasic ‘protest-despair’...

  13. The death of a pet: implications for loss and bereavement across the lifespan

    Contributor(s):: Podrazik, Donna, Shackford, Shane, Becker, Louis, Heckert, Troy

  14. Loss: Divorce, Separation, and Bereavement

    Contributor(s):: Snyder, Jamie

  15. Effects of early separation on the dairy cow and calf 1. Separation at 6 h, 1 day and 4 days after birth

    Contributor(s):: Weary, D. M., Chua, B.

    The aim of this study was to evaluate the effects of age of separation on the behavioural responses of the dairy calf and cow. Calves were separated from their dams 6 h, 1 day, or 4 days after birth (n=9 cow-calf pairs in each of the 3 treatment groups) and behaviour was video and audio taped...

  16. Responses of piglets to early separation from the sow

    Contributor(s):: Weary, D. M., Appleby, M. C., Fraser, D.

    Two experiments were conducted to examine the effect of age and diet on behavioural responses of piglets to separation from the sow. In experiment 1, the vocalizations of piglets were recorded during short term (10 min) isolation from the sow and litter-mates at 1, 2, 3 and 4 weeks of age. From...

  17. Behavioural relationships between Djallonke and Sahellian ewes and their lambs during the first 24 h post-partum

    Contributor(s):: Asante, Y. A., Oppong-Anane, K., Awotwi, E. K.

    Djallonke, Sahellian crossbred ewes and their lambs were tested to find out their behavioural response to separation and their mutual recognition within the first 24 h post-partum. To determine whether age, sex, birth weight of lambs and parity of dams had an effect on these post-partum...

  18. Plasma cortisol levels of dogs at a county animal shelter

    Contributor(s):: Hennessy, M. B., Davis, H. N., Williams, M. T., Mellott, C., Douglas, C. W.

    Groups of dogs confined in a shelter for their 1st, 2nd, or 3rd day had higher cortisol levels than a group maintained in the shelter for more than 9 days. Dogs in the shelter for an intermediate period (4-9 days) had intermediate levels of cortisol. The cortisol concentrations of dogs during...

  19. Effects of early separation on the dairy cow and calf 1. Separation at 6 h, 1 day and 4 days after birth

    Contributor(s):: Weary, D. M., Chua, B.

    The aim of this study was to evaluate the effects of age of separation on the behavioural responses of the dairy calf and cow. Calves were separated from their dams 6 h, 1 day, or 4 days after birth (n=9 cow-calf pairs in each of the 3 treatment groups) and behaviour was video and audio taped...

  20. Effects of immediate and early post-partum separation on maintenance of maternal responsiveness in parturient multiparous goats

    Contributor(s):: Ramirez, A., Quiles, A., Hevia, M. L., Sotillo, F., Ramirez, M. C.

    50 Murcia-Granada goats and their 82 kids were used in this study. Goats were kept away from their kids for 0.5 or 1 h when the separation took place immediately after birth, and for 1, 8 or 24 h when it took place after a 5-min post-partum contact between mother and young. At the end of the...
