Positive welfare is more than the absence of negative experiences. Nevertheless, there are few feasible animal-based measures for positive welfare. This study aimed to investigate whether object and social play behaviours in pigs, which is believed to trigger positive emotions, is linked to...
Disparities in activity levels and learning ability between Djungarian hamster (Phodopus sungorus) and Roborovskii hamster (Phodopus roborovskii)

The Djungarian hamster and the Roborovskii hamster belong to the same genus of Phodopus. However, the Djungarian hamster is tame and shows sedative behavior, while Roborovskii hamster is not tame and shows high levels of locomotor activity. Hyperactivity occurs in animals with tameless behavior....

| Contributor(s):: Miyaji, K., Kato, M., Ohtani, N., Ohta, M.
The objective of this study was to evaluate the effects of diet on the feline stress response by measuring plasma and urinary cortisol. A study diet was developed with a unique combination of nutrients that supports the management of stressful situations. The specific formulation of the diet...
The effects of drug detection training on behavioral reactivity and blood neurotransmitter levels in drug detection dogs: a preliminary study
| Contributor(s):: Riva, J., Marelli, S. P., Redaelli, V., Bondiolotti, G. P., Sforzini, E., Santoro, M. M., Carenzi, C., Verga, M., Luzi, F.
The aim of the present study was to analyze the effects of drug detection training on behavior and blood neurotransmitter levels in drug detection dogs so as to investigate some variables influencing dog reactivity and responsiveness to training. In all, 20 dogs were sampled out of the Guardia di...

Electric fencing reduces heron predation at northeastern trout hatcheries
| Contributor(s):: Mark E. Tobin, James F. Glahn, Erica S. Rasmussen
Great blue herons (Ardea herodius) are the most common avian predator at commercial trout hatcheries in the northeastern United States. We evaluated a 2-strand electric fence for excluding this species from raceways at 2 commercial trout hatcheries in central Pennsylvania. Fences consisted of...

Anxiety related behavioural disorders and neurotransmitters in dogs
| Contributor(s):: Riva, J., Bondiolotti, G., Michelazzi, M., Verga, M., Carenzi, C.
The aim of this research has been to verify possible correlations among some neurotransmitters and anxiety related behavioural disorders in the domestic dog. Twenty dogs affected by anxiety related behavioural disorders and 13 control dogs were studied. The dogs' behaviour has been analysed...
Stimulation of serotonin (5-HT) activity reduces spontaneous stereotypies in female but not in male bank voles ( Clethrionomys glareolus ). Stereotyping female voles as a new animal model for human anxiety and mood disorders?
| Contributor(s):: Schoenecker, B., Heller, K. E.
Spontaneously stereotyping female and male bank voles were injected daily (except on days assigned for monitoring behaviour) during 3 weeks with placebo, the neurolepticum clozapine or the SSRI antidepressant citalopram. Clozapine blocks dopamine (DA) receptors and acts as a partial serotonin...
The involvement of dopamine (DA) and serotonin (5-HT) in stress-induced stereotypies in bank voles ( Clethrionomys glareolus )
In order to clarify the dependency of stress-induced stereotypies on dopamine (DA) and serotonin (5-HT) functioning, undisturbed and acutely stressed stereotyping bank voles were treated during 3 weeks with the commonly used human atypical neurolepticum clozapine and the SSRI antidepressant...
Dietary tryptophan supplementation in privately owned mildly anxious dogs
| Contributor(s):: Bosch, G., Beerda, B., Beynen, A. C., van der Borg, J. A. M., van der Poel, A. F. B., Hendriks, W. H.
Food composition has been reported to influence mood and behaviour in humans and animals and it could help to reduce unwanted behaviour in dogs. Anxiety-related behaviour is associated with the functioning of the central serotonergic system and here it was investigated if dietary supplementation...
Diagnosis and treatement methods in separation anxiety in dogs
| Contributor(s):: Asztalos, L., Papuc, I., Lazar, I.
A group of 60 dogs from different races, ages and genders in Romania were studied [date not given]. We used clinical and semiological methods and a paraclinical test for the diagnosis of separation anxiety, but the most important and relevant information were the anamnetic dates that the owners...
Blood concentrations of serotonin, cortisol and dehydroepiandrosterone in aggressive dogs
| Contributor(s):: Rosado, B., Garcia-Belenguer, S., Leon, M., Chacon, G., Villegas, A., Palacio, J.
Canine aggression directed towards people is the most frequent reason for referral to behaviour practices. In order to provide new and improved diagnostic and therapeutic approaches for this problem, it is necessary to make an in-depth investigation of the biological basis of aggression in this...
Aggression in replacement grower and finisher gilts fed a short-term high-tryptophan diet and the effect of long-term human-animal interaction
| Contributor(s):: Poletto, R., Meisel, R. L., Richert, B. T., Cheng, H. W., Marchant-Forde, J. N.
Aggression can be a major problem for swine production as it negatively impacts the pigs' health and welfare. Increasing tryptophan (TRP) intake to raise brain serotonin (5-HT) - key for aggression control, and long-term positive social handling can reduce stress in pigs. Objective was to...
Chronic increase of dietary L-tryptophan decreases gentle feather pecking behaviour
| Contributor(s):: Hierden, Y. M. van, Koolhaas, J. M., Korte, S. M.
Many studies show the involvement of the serotonergic (5-HT) system in the performance of abnormal behaviour in both human and animals. Recently, we showed that acute reduction of 5-HT turnover in the forebrain, increased gentle and severe feather pecking behaviour in chicks from a high (HFP) and...
