Evaluation of a novel rodenticide: acute sub-lethal effects of a methaemoglobin-inducing agent
Contributor(s):: Quy, R. J., Gibson, T. J., Lambert, M. S., Eason, C. T., Gregory, N. G.
In a series of experiments the welfare of para-aminovalerophenone (PAVP) sub-lethally poisoned rats ( Rattus norvegicus) was assessed. The experiments: (i) examined the acute methaemoglobin (MetHb) profile over time; (ii) refined the LD50 estimate for PAVP in adult female rats; (iii) developed...
Measuring heart rate variability in horses to investigate the autonomic nervous system activity - pros and cons of different methods
Contributor(s):: Stucke, D., Ruse, M. G., Lebelt, D.
Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses....
Heart rate variability during a working memory task: does touching a dog or person affect the response?
Contributor(s):: Gee, N. R., Friedmann, E., Stendahl, M., Fisk, A., Coglitore, V.
The presence of a dog has been associated with reduced responses to stressors in several, but not all, previous studies. The presence of a dog has also been related to improved performance on some cognitive tasks. The current study was designed to evaluate the effect of touching a dog on stress...
Do audible and ultrasonic sounds of intensities common in animal facilities affect the autonomic nervous system of rodents?
Contributor(s):: Burwell, A. K., Baldwin, A. L.
In animal facilities, noises, often poorly controlled, occur over a wide range of frequencies and intensities. Evidence demonstrates that audible noise and ultrasound have deleterious effects on rodent physiology, but it is not known how they affect the autonomic nervous system (ANS). This study...
Equine stereotypic behaviors: causation, occurrence, and prevention
Contributor(s):: Sarrafchi, A., Blokhuis, H. J.
There are strong suggestions that equine stereotypies are connected to poor welfare and a suboptimal management and/or stabling environment. Different forms of equine stereotypic behaviors have been described. Crib biting, weaving, and box walking are considered the most prevalent. Several...
Evaluating the effect of early neurological stimulation on the development and training of mine detection dogs
Contributor(s):: Schoon, A., Berntsen, T. G.
Early neurological stimulation (ENS) has been proposed to enhance the natural abilities of dogs. This kind of stimulation involves subjecting pups aged between 3 and 16 days to mild forms of stimulation leading to "stress," and is said to lead to faster maturation and better problem-solving...
Periods of early development and the effects of stimulation and social experiences in the canine
Contributor(s):: Battaglia, C. L.
It is not capacity that explains the differences that exist between individuals, because most seem to have far more capacity than they will ever use. The differences that exist between individuals seem to be related to something else. Researchers have studied these phenomena and have looked for...
Heart rate variability in horses engaged in equine-assisted activities

Human-animal relationships in the Norwegian dairy goat industry: assessment of pain and provision of veterinary treatment (Part II)

Neuromechanical control of locomotion in intact and incomplete spinal cord injured rats
Contributor(s):: Anil Kumar Thota
Rodent models are being extensively used to investigate the effects of traumatic injury and to develop and assess the mechanisms of repair and regeneration. We present quantitative assessment of 2D kinematics of overground walking and for the first time 3D joint angle kinematics of all four limbs...
Psychosocial and psychophysiological effects of human-animal interactions: The possible role of oxytocin
out of 5 stars
| 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...
The hereditary " fixing " of individually acquired behaviour of animals and the origin of instincts
| Contributor(s):: Krusinskii, L. V.
ELEVEN German Shepherd dogs [Alsatian] of different ages were trained (1) to bring objects to the trainer, (2) to bring them on a command, (3) to get an object and then bring it on a command, and (4) to go when commanded and bring an object without a command. The best performances of these 4...

Docosahexaenoic acid and neurologic development in animals
| Contributor(s):: Heinemann, K. M., Bauer, J. E.
Analysis of data in puppies has revealed that feeding diets enriched in DHA to the dams during gestation and lactation and after weaning results in the accumulation of DHA in plasma lipids, which is associated with improvements in neurologic development, as indicated by the ERG response....
Assessment of mental stress in warmblood horses: heart rate variability in comparison to heart rate and selected behavioural parameters
| Contributor(s):: Rietmann, T. R., Stuart, A. E. A., Bernasconi, P., Stauffacher, M., Auer, J. A., Weishaupt, M. A.
The aim of the study was to investigate whether heart rate variability (HRV) could assess alterations of the autonomic nervous system (ANS) at different levels of excitement. The behavioural and physiological responses of 20 warmblood horses to a challenging ground exercise task were studied....
Perseverative responding and the aetiology of equine oral stereotypy
| Contributor(s):: Hemmings, A., McBride, S. D., Hale, C. E.
Research suggests that environmentally-induced (spontaneous) stereotypies arise from dysregulation of the basal ganglia. Basal ganglia dysfunction can also expresses itself as aberrations in learning task performance. As a result, several studies have demonstrated a strong link between...
Exploratory study of stress-buffering response patterns from interaction with a therapy dog
| Contributor(s):: Barker, S. B., Knisely, J. S., McCain, N. L., Schubert, C. M., Pandurangi, A. K.
This exploratory study builds on existing research on the physiological stress response to human-animal interactions in a non-clinical sample of adult dog-owners interacting with their own or an unfamiliar therapy dog under similar conditions. Participants were therapy-dog owners (TDO group; n=5)...

| Contributor(s):: Rodriguez, P., Dalmau, A., Ruiz-de-la-Torre, J. L., Manteca, X., Jensen, E. W., Rodriguez, B., Litvan, H., Velarde, A.
The aim of this study was to assess unconsciousness in pigs during exposure to CO2 through changes in the middle latency auditory evoke potentials (MLAEP) of the central nervous system (CNS), blood parameters (pH, carbon dioxide partial pressure [pCO2], oxygen partial pressure [pO2], oxygen...
Is sodium fluoroacetate (1080) a humane poison?
| Contributor(s):: Sherley, M.
Sodium fluoroacetate (1080) is widely used for the control of vertebrate pests in Australia. While the ecological impact of 1080 baiting on non-target species has been the subject of ongoing research, the animal welfare implications of this practice have received little attention. Literature...
Relationships between pathology and pain severities: a review
| Contributor(s):: Gregory, N. G.
The relationships between pathology severity and pain severity are reviewed using the literature available for humans. The aim is to help veterinary radiologists, physicians and pathologists recognise the disorders in which severity of a lesion is likely to be related to the severity of pain or...
