The use of a mirror reduces isolation stress in horses being transported by trailer
Contributor(s):: Kay, R., Hall, C.
Horse trailers are a common form of transportation for horses and ponies and often require the animal to travel alone or with a single companion. The current study investigated the effect of transporting horses alone, in company or with an acrylic safety mirror (measuring 81 cm x 61.5 cm) that...
Vocalisations of the adult female domestic pig during a standard human approach test and their relationships with behavioural and heart rate measures
Contributor(s):: Marchant, J. N., Whittaker, X., Broom, D. M.
Vocal communication in the domestic pig is generally not well documented. The aim of this experiment was to categorise and ascribe the function of the vocalisations of 67 Large White x Landrace gilts during a standard human approach test. At testing, each group of 3-5 gilts was moved to a...
Behavioural and physiological responses to an acute stressor in crib-biting and control horses
Contributor(s):: Bachmann, I., Bernasconi, P., Herrmann, R., Weishaupt, M. A., Stauffacher, M.
The responses of eleven pairs of crib-biting and non-crib-biting horses (controls) to an arousal-inducing stimulus were studied. Video-observation of the horses revealed that crib-biting horses spent between 10.4 and 64.7% of their stabling time performing the stereotypy. During the first 2 days...
Do horses generalise between objects during habituation?
Contributor(s):: Christensen, J. W., Zharkikh, T., Ladewig, J.
Habituation to frightening stimuli plays an important role in horse training. To investigate the extent to which horses generalize between different visual objects, 2-year-old stallions were habituated to feeding from a container placed inside a test arena and assigned as TEST (n=12) or REFERENCE...
Does feed-back from a nest affect periparturient behaviour, heart rate and circulatory cortisol and oxytocin in gilts?
Contributor(s):: Damm, B. I., Pedersen, L. J., Marchant-Forde, J. N., Gilbert, C. L.
To determine the effects of feed-back from a farrowing nest on periparturient behaviour, heart rate and hormones, 20 gilts housed in Schmid pens were permitted to build a nest of peat, straw and branches. Ten gilts then had their nest removed (NR) 10 h after the onset of nest-building and again...
Effects of handling on behaviour and heart rate in Konik horses: comparison of stable and forest reared youngstock
Contributor(s):: Jezierski, T., Jaworski, Z., Gorecka, A.
30 foals and young Konik horses born in 3 consecutive years and reared up to weaning, either in a forest reserve (R) or conventional stable (S), were compared with respect to behavioural reactions and heart rate (HR) during handling manipulations. The foals were randomly allocated within sex and...
Emotional reactions to learning in cattle
Contributor(s):: Hagen, K., Broom, D. M.
It has been suggested that during instrumental learning, animals are likely to react emotionally to the reinforcer. They may in addition react emotionally to their own achievements. These reactions are of interest with regard to the animals' capacity for self-awareness. Therefore, we devised a...
Impact of riding in a coercively obtained Rollkur posture on welfare and fear of performance horses
Contributor(s):: Borstel, U. U. von, Duncan, I. J. H., Shoveller, A. K., Merkies, K., Keeling, L. J., Millman, S. T.
Rollkur, the usually coercively obtained hyperflexion of the horse's neck, is employed as a training method by some dressage riders; however, its use is controversial as it may cause discomfort and adversely affect the horse's welfare. The objectives of this study were to determine: (1) if horses...
Individual differences in aggression and physiology in peri-pubertal breeding gilts
Contributor(s):: Geverink, N. A., Schouten, W. G. P., Gort, G., Wiegant, V. M.
Several recent studies on pigs have demonstrated a relationship between the degree of resistance displayed in a so-called "backtest" and a variety of behavioural and physiological responses in piglets and young fattening pigs. However, the discussion about the predictive power of the backtest is...
Individual differences in behaviour, physiology and pathology in breeding gilts housed in groups or stalls
A number of studies in young pigs have demonstrated a relation between a variety of behavioural and physiological features and the degree of resistance displayed early in life in a so-called "backtest". The current study aimed at investigating the relation between the backtest response and the...
Physiological and behavioural alterations in disbudded goat kids with and without local anaesthesia
Contributor(s):: Alvarez, L., Nava, R. A., Ramirez, A., Ramirez, E., Gutierrez, J.
The physiological and behavioural responses were evaluated in goat kids that were disbudded either with or without local anaesthesia, in a study with 56 animals randomly allocated among five groups. The anaesthesia/disbudding group (AD, n=12) was treated with 2 mL 2% lidocaine (L2
Physiological measurements after ovariohysterectomy in dogs: what's normal?
Contributor(s):: Hansen, B. D., Hardie, E. M., Carroll, G. S.
Twenty-two pet dogs presented to the North Carolina State University Veterinary Teaching Hospital for elective ovariohysterectomy were treated with oxymorphone 2.5 mg/msuperscript 2 (Surgery-O group, 11 dogs) or placebo (Surgery-P group, 11 dogs) immediately before the induction of anaesthesia...
Some effects of repeated handling and the use of a mask on stress responses in zebu cattle during restraint
Contributor(s):: Andrade, O., Orihuela, A., Solano, J., Galina, C. S.
The objective of this investigation was to evaluate the effect of repeated handling and the use of a mask on the order of entry, temperament, cortisol concentration and heart and respiratory rates of Brahman cattle during restraint in a squeeze chute. In the first experiment, 18 cows were...
The behavioural, physiological and immunological responses of lambs from two rearing systems and two genotypes to exposure to humans
Contributor(s):: Goddard, P. J., Fawcett, A. R., Macdonald, A. J., Reid, H. W.
96 lambs of 2 genotypes (Scottish Blackface: BF and Texel x (Blue-faced Leicester x Scottish Blackface): T) were studied. From birth to weaning 1 of 2 management regimes was applied: extensive (E), whereby animals were handled as little as possible or semi-intensive (I), in which lambs...
The effects of two different amounts of dietary grain on the digestibility of the diet and behaviour of intensively managed horses
Contributor(s):: Freire, R., Clegg, H. A., Buckley, P., Friend, M. A., McGreevy, P. D.
The current experiment examined the effect of switching from a moderate grain diet to a high grain diet, as are typically fed to intensively managed horses, on some behavioural and physiological (oro-caecal transit time [OCTT], digestibility, plasma cortisol concentrations and heart rate)...

| Contributor(s):: Andrea Beetz, Kerstin Uvnäs-Moberg, Henri Julius, Kurt Kotrschal
During the last decade it has become more widely accepted that pet ownership and animal assistance in therapy and education may have a multitude of positive effects on humans. Here, we review the evidence from 69 original studies on human-animal interactions (HAI) which met our inclusion...
Are women's dogs less stressed and healthier than men's dogs? An investigation in the waiting room of a veterinary hospital
| Contributor(s):: Boere, V., Scalon, M. C., Wiedemann, G. G. S.
Dogs are able of discriminate several human behaviors, behaving of corresponding way. Some studies showed that the dogs possess propensities to be more sociable and less stressed when manipulated by women regarding the dogs manipulated by men. We investigated in this study if the dogs accompanied...
