Physiological effects of human-animal positive interaction in dogs - review of the literature
Contributor(s):: Pop, D., Rusu, A. S., Pop-Vancia, V., Papuc, I., Constantinescu, R., Miresan, V.
Positive human-animal interactions (HAI) are known to increase the quality of life in both humans and dogs. Although there are several reviews on the benefits of HAI in humans, there are no reviews on the effects of positive HAI in dogs. Therefore, the aim of this paper is to provide a review of...

Neurophysiological correlates of affiliative behaviour between humans and dogs
Contributor(s):: Odendaal, J. S. J., Meintjes, R. A.
Few physiological parameters for positive human-companion animal contact have been identified and those that are established have all been in humans. The implication is that if the physiological reactions are mutual, dogs would experience the same psychological benefits from these...
A study of cortisol and beta-endorphin levels in stereotypic and normal Thoroughbreds
Contributor(s):: Pell, S. M., McGreevy, P. D.
Plasma and salivary cortisol levels were measured in stereotypic (n=46) and normal horses (n=46). No significant differences were found between the 2 groups of horses. The correlation between plasma and salivary cortisol concentrations of individual horses (n=66) was also examined. A significant...
Naloxone cannot abolish the lack of oxytocin release during unexperienced suckling of dairy cows. (Special issue: Suckling)
Contributor(s):: Kraetzl, W. D., Tancin, V., Schams, D., Bruckmaier, R. M.
To evaluate the role of opioids for the regulation of oxytocin release in response to teat stimulation, 10 brown-Swiss dairy cows in mid-lactation were randomized to two experiments. In the first experiment, four cows without previous suckling experience were suckled by an alien calf between two...

The relationship between housing and social rank on cortisol, beta -endorphin and dynorphin (1-13) secretion in sows
Contributor(s):: Zanella, A. J., Brunner, P., Unshelm, J., Mendl, M. T., Broom, D. M.
Endogenous opioids and glucocorticoids may be useful welfare indicators in pigs. Measures of plasma cortisol were carried out in plasma samples collected hourly, from 8:00 to 17:00 h from High Ranking (HR) (n = 5) Middle Ranking (MR) (n = 7) and Low Ranking (LR) (n = 4) group housed sows and from...
The effect of diet on cribbing behavior and plasma beta -endorphin in horses
Contributor(s):: Gillham, S. B., Dodman, N. H., Shuster, L., Kream, R., Rand, W.
Five cribbing horses and six control horses were used in a latin square design dietary study to investigate the effects of different diets on the frequency of cribbing behaviour and plasma levels of beta-endorphin. Feeding grain or sweetened grain rations significantly increased the cribbing...
The effect of naloxone on nursing behavior in Brahman calves
Contributor(s):: Lay, D. C., Jr., Friend, T. H., Dellmeier, G. R., Randel, R. D., Bowers, C. L., Mal, M. E., Zavala, P.
In 3 experiments in which calves were injected s.c. with saline or naloxone (at 1, 1.5 or 3 mg/kg body wt), no significant effects of naloxone on sucking behaviour were observed, although there was a tendency for naloxone-treated calves to spend less time sucking than did saline-treated calves....
Behavioural and hormonal responses to acute surgical stress in sheep
Contributor(s):: Fell, L. R., Shutt, D. A.
A combination of plasma cortisol and beta -endorphin measurement, behavioural observation and estimation of aversion to humans (by an arena test) was used to assess the response to the modified mules operation in 6- to 7-month-old Merino wethers. The operation involves the surgical removal of...
Effect of human contact on heart rate of pigs
Contributor(s):: Geers, R., Janssens, G., Ville, H., Bleus, E., Gerard, H., Janssens, S., Jourquin, J.
Pigs were selected at random from 3 lines (homozygous halothane positive, homozygous negative and the heterozygotes). They were housed for 4 weeks within standardized environmental conditions with 6 pigs per pen corresponding to each of the 3 lines with 2 treatment combinations (6x3x2). Half of...
Lack of evidence for stress being caused to pigs by witnessing the slaughter of conspecifics
Contributor(s):: Anil, M. H., McKinstry, J. L., Field, M., Rodway, R. G.
15 catheterized pigs (Duroc x Large White) of mixed sex of between 35 and 65 kg body weight were allowed to see the stunning and sticking (exsanguination) of pigs in a nearby pen. Each witness pig was placed in a hammock giving it a full view of another pen in which 2 other pigs were put. One of...
Travel sickness and meat quality in pigs
Contributor(s):: Bradshaw, R. H., Randall, J. M., Forsling, M. L., Rodway, R., Goode, J. A., Brown, S. N., Broom, D. M.
An experiment was conducted to investigate the incidence of travel sickness in pigs, specific hormone concentrations at exsanguination and subsequent meat quality. Fifty, 80-kg slaughter pigs were transported on a lorry for 4.5 h. During the journey, behavioural observations of the individually...
