Stability of Owners’ Perceptions of the Behavioral Style of Their Cats
Contributor(s):: Elvers, Greg C., Lawriw, Alexander N., Chambers, Taylor N.
In humans, personality is relatively stable across the adult life- span and various situations. Can the same be said of the personality of cats? Primary caregivers of cats thought about their cats in four situations: 1) home alone with the cat, 2) an unknown plumber arrives, 3) during a...
Stability of social hierarchy in growing female pigs and pregnant sows
Contributor(s):: Parent, Jean-Philippe, Meunier-Salaün, Marie-Christine, Vasseur, Elsa, Bergeron, Renée
Conflicting results between dominance tests and repetitions of these tests over time in pigs may result from a lack of stability of their social hierarchy. The objectives of this study were to compare five methods to measure social hierarchy and to examine the stability of test results over time...
Same-sized fish groups increase aggressive interaction of sex-reversed males Nile tilapia GIFT strain
Contributor(s):: Boscolo, Camila Nomura Pereira, Morais, Rosana Nogueira, Gonçalves-de-Freitas, Eliane
Animals with similar fighting ability can fight harder and longer than animals in asymmetric contests. Thus, the selection of fish by size similarity in husbandry might increase aggressive interactions, and lead to social instability in socially organized fish. We tested the hypothesis that...
Long-term stability of Avoidance Distance tests for on-farm assessment of dairy cow relationship to humans in alpine traditional husbandry systems
Contributor(s):: Battini, Monica, Andreoli, Elena, Barbieri, Sara, Mattiello, Silvana
The present study investigates the long-term stability of two behaviour tests used to evaluate the human–animal relationship as well as gather information to refine on-farm welfare assessment protocols in alpine husbandry systems. Two tests, Avoidance Distance (AD) and Avoidance Distance at the...
High rates of aggression do not predict rates of trauma in captive groups of macaques
Contributor(s):: Beisner, Brianne A., Wooddell, Lauren J., Hannibal, Darcy L., Nathman, Amy, McCowan, Brenda
Socially inflicted traumas are a major concern for the management of captive groups of rhesus macaques. Rhesus macaques are the most commonly used nonhuman primate in biomedical research, and social housing is optimal for promoting psychological well-being. However, trauma is frequent due to a...
Expanding on current methods employed for investigating pet food stability
| Contributor(s):: Jessica Jayne Learey
The Australian petfood sector continues to grow due to the 'humanisation' of pets. Ingredients added to petfood have the potential to degrade to harmful products making detection important. In this research various analytical methods were adapted to improve detection of products found...
Long-term effects of robotic hippotherapy on dynamic postural stability in cerebral palsy
| Contributor(s):: Young Joo Cha, Megan Stanley, Tim Shurtleff, Joshua S. H. You
Dynamic postural instability is a common neuromuscular impairment in cerebral palsy (CP), which often includes balance dysfunction and an associated risk of serious falls. Robotic hippotherapy has recently become a widespread clinical application to facilitate postural core stabilization,...

Maximum permissible load for Yonaguni ponies (Japanese landrace horses) trotting over a short, straight course
| Contributor(s):: Matsuura, A., Mano, H., Irimajiri, M., Hodate, K.
This study aimed to determine the load-bearing capacity of trotting Yonaguni ponies using gait analysis. The Yonaguni pony is one of the Japanese landrace horses, and has normal gait characteristics when trotting. As a breed they are small in stature and hence susceptible to the effect of the...

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...
Analysis of the phenotypic link between behavioural traits at mixing and increased long-term social stability in group-housed pigs
| Contributor(s):: Desire, S., Turner, S. P., D'Eath, R. B., Doeschl-Wilson, A. B., Lewis, C. R. G., Roehe, R.
Mixing of growing pigs results in aggressive contests between group members. As aggression serves to establish dominance relationships, it is possible that increased initial aggression may facilitate the formation of social hierarchies. The objective of the study was to investigate whether there...
Influences of various factors on cows' entrance order into the milking parlour
| Contributor(s):: Polikarpus, A., Kaart, T., Mootse, H., Rosa, G. de, Arney, D.
This study investigates the stability of the milking order of cows entering into the milking parlour of a commercial dairy herd, and changes to this order consequent to a change in health status and a change in the membership of the group of cows being milked. In large herds it is difficult for...
Applied personality assessment in domestic dogs: limitations and caveats
| Contributor(s):: Rayment, D. J., Groef, B. de, Peters, R. A., Marston, L. C.
Modern behavioural tests for domestic dogs are commonly employed across a variety of fields, including the assessment of companion, assistance, working and sporting dogs. While there is increasing scientific attention on the development and evaluation of behavioural tests used to assess...
Systematic investigation of the stability of food preferences in captive orangutans: implications for positive reinforcement training
| Contributor(s):: Clay, A. W., Bloomsmith, M. A., Marr, M. J., Maple, T. L.
Using preference-assessment tests with humans in conjunction with behavioral modification sessions has been a regular component of almost all operant conditioning programs with mentally challenged humans. This has been very effective in improving the efficiency of behavioral training in these...
The effect of physiotherapy intervention to the pelvic region of experienced riders on seated postural stability and the symmetry of pressure distribution to the saddle: a preliminary study
| Contributor(s):: Nevison, C. M., Timmis, M. A.
It is commonplace for trainers and judges to comment that riders are "crooked" or "collapsed in the hip." This asymmetrical posture will likely have a significant effect on stability/balance and may subsequently have a detrimental effect on performance. Although the effects of asymmetry on...
The welfare ethics of the commercial killing of free-ranging kangaroos: an evaluation of the benefits and costs of the industry
| Contributor(s):: Ben-Ami, D., Boom, K., Boronyak, L., Townend, C., Ramp, D., Croft, D. B., Bekoff, M.
The commercial killing of kangaroos provides multiple benefits to society, but also causes both deliberate and unintended harms to kangaroos. The ethics of the kangaroo industry is assessed in terms of whether the assumed benefits justify the welfare costs. An analysis of the stated benefits...
