A case study: fecal corticosteroid and behavior as indicators of welfare during relocation of an Asian elephant
Contributor(s):: Laws, N., Ganswindt, A., Heistermann, M., Harris, M., Harris, S., Sherwin, C.
This study was a preliminary investigation of an enzyme immunoassay for measuring fecal glucocorticoid metabolites in a male Asian elephant (Elephas maximus) by investigating changes in behavior and cortisol metabolite excretion associated with a putative stressful event. The study collected...

Emotional stress release - a therapy option for atopy in dogs
Contributor(s):: Luder, A.
The emotional stress release is a creative and effective treatment option. Here in particular the interaction between man and animal will be identified to detect and to discuss possible projections of the keeper on the animal. The ESR is a methodology that is used for animals with recurrent...
Behavioural and physiological consequences of acute social defeat in growing gilts: effects of the social environment
Contributor(s):: Ruis, M. A. W., Groot, J. de, Brake, J. H. A. te, Ekkel, E. D., Burgwal, J. A. van de, Erkens, J. H. F., Engel, B., Buist, W. G., Blokhuis, H. J., Koolhaas, J. M.
Endocrine, behavioural and immunological processes, together with body growth, were evaluated in gilts that were defeated at 10 weeks of age in resident-intruder tests. Immediately after defeat, gilts were either separated from or reunited with a familiar conspecific (litter-mate; always a...
Behavioural, endocrine and immune consequences of mixing in weaned piglets
Contributor(s):: Merlot, E., Meunier-Salaun, M. C., Prunier, A.
Mixing piglets at weaning increases plasma cortisol concentrations and agonistic behaviour. In contrast to what is observed in older pigs, studies failed to show any effect of social environment on other behavioural variables or on immune function. The lack of effect of mixing may not reflect an...
The effect of a gradual separation from the mother on later behavioral, immune and endocrine alterations in artificially reared lambs
Contributor(s):: Sevi, A., Caroprese, M., Annicchiarico, G., Albenzio, M., Taibi, L., Muscio, A.
The aim of the experiment was to compare the welfare and weight gains of artificially reared lambs when gradually separated from their mothers or separated from them early and immediately or gradually moved from maternal to reconstituted milk. Forty Comisana lambs were assigned to a control...
The effects of regular visual contact with human beings on fear, stress, antibody and growth responses in broiler chickens
Contributor(s):: Zulkifli, I., Gilbert, J., Liew, P. K., Ginsos, J.
This study investigated the effects of regular visual contact at various ages on tonic immobility (TI) and heterophil/lymphocyte ratio (HLR) reactions to handling and crating, antibody production, growth performance and feed conversion ratios in commercial broiler chicks. Broiler chicks were...
Behaviour and welfare in relation to pathology
Contributor(s):: Broom, D. M.
Behaviour is an important way of adapting to disease for individuals and selective pressures resulting from disease have had major consequences for the evolution of behaviour. Behaviour, adrenal and other physiological responses, immunological responses and brain activity all help in coping with...
Neonatal handling of Amazon parrots alters the stress response and immune function
Contributor(s):: Collette, J. C., Millam, J. R., Klasing, K. C., Wakenell, P. S.
The influence of neonatal handling on behaviour and immune function was assessed in Orange-winged Amazon parrots (Amazona amazonica). Chicks (n=11) were gently handled daily from 25 days of age until 38 days post-fledging, while control chicks (n=9) were not handled. At 10 days post-fledging...
Personality traits and the effects of DHA supplementation in the budgerigar ( Melopsittacus undulatus )
Contributor(s):: Callicrate, T. E., Siewerdt, F., Koutsos, E., Estevez, I.
We investigated the hypotheses that a bold-shy personality axis exists in the budgerigar (Melopsittacus undulatus) and that dietary docosahexaenoic acid (DHA) supplementation has a significant effect on budgerigar personality and immune responses. DHA is an integral component of the brain known...
