Latitudinal variation in diet and patterns of human interaction in the marine otter
Contributor(s):: Mangel, J. C., Whitty, T., Medina-Vogel, G., Alfaro-Shigueto, J., Caceres, C., Godley, B. J.
The marine otter (Lontra felina) inhabits patches of rocky coastline from central Peru to southern Chile and is classified as Endangered by the IUCN. Given the limited information available about the species, we set out to assess marine otter diet with a view to detecting latitudinal differences,...
Stepping and kicking behaviour during milking in relation to response in human-animal interaction test and clinical health in loose housed dairy cows
Contributor(s):: Rousing, T., Bonde, M., Badsberg, J. H., Sorensen, J. T.
Associations between kicking and stepping behaviour during milking and response to humans, getting up behaviour as well as clinical health status in loose housed dairy cows were investigated. During a 12-month period behavioural and clinical data from 10 commercial Danish dairy herds were...
Ethical issues associated with sheep fly strike research, prevention, and control
Contributor(s):: Morris, M. C.
This paper deals with ethical issues associated with fly strike research, prevention and control. It is argued that in their attempt to find control solutions and to understand the disorder, Australasian researchers increase sheep suffering by conducting experiments that artificially induce fly...
Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model
Contributor(s):: Patullo, B. W., Baird, H. P., Macmillan, D. L.
Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...
Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs
| Contributor(s):: Wall, D., Paterson, B., Mohan, R.
Behaviour of juvenile mud crabs, Scylla serrata (70–90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better...
Cannibalism in juvenile blue-swimmer crabs Portunus pelagicus (Linnaeus, 1766): effects of body size, moult stage and refuge availability
| Contributor(s):: Marshall, S., Warburton, K., Paterson, B., Mann, D.
Factors influencing the rate of cannibalism in juvenile blue-swimmer crabs Portunus pelagicus were investigated under controlled conditions using time-lapse video recordings. This study was undertaken to improve blue-swimmer crab culture and experimentally addressed (1) prey vulnerability (2)...
Claw removal and feeding ability in the edible crab, Cancer pagurus : implications for fishery practice
| Contributor(s):: Patterson, L., Dick, J. T. A., Elwood, R. W.
Feeding ability and motivation were assessed in the edible crab, Cancer pagurus, to investigate how the fishery practice of de-clawing may affect live crabs returned to the sea. Crabs were either induced to autotomise one claw, or were only handled, before they were offered food. Initially,...
Estimating the diet of urban birds: the problems of anthropogenic food and food digestibility
| Contributor(s):: Ottoni, I., Oliveira, F. F. R. de, Young, R. J.
A variety of methods exist for assessing the diets of wild birds, each of which has its strengths and weaknesses. The objective of this study was to compare diet data collected in parallel by behavioural observations and faecal analysis from an urban population of Penelope superciliaris...
Investigations on genetic disease resistance in swine - a contribution to the reduction of pain, suffering and damage in farm animals.
| Contributor(s):: Reiner, G.
This review deals with genetic disease resistance in pigs as a prospective opportunity to reduce pain, suffering and damage in swine production. Even under favourable terms of housing and management, infectious diseases are wide-spread, and have to be ranked among the major sources for suffering...
Resting and social behaviour of dairy heifers housed in slatted floor pens with different sized bedded lying areas
| Contributor(s):: Nielsen, L. H., Mogensen, L., Krohn, C., Hindhede, J., Sorensen, J. T.
The hypothesis that an increase in the straw bedded resting area for group housed heifers would increase synchronization of resting behaviour and decrease aggressive and abnormal behaviour was tested. An experiment was conducted on 2 Danish commercial dairy farms with 20 Danish Friesian heifers...
Suffering in diseased pigs as expressed by behavioural, clinical and clinical-chemical traits, in a well defined parasite model
| Contributor(s):: Reiner, G., Hubner, K., Hepp, S.
In assessing the quality of life of farm animals, the absence of disease has been given highest priority. During the course of infection, sickness and suffering refer to a coordinated set of behavioural and physiological changes. For a better understanding and assessment of animal suffering due...
Animal behaviour, animal welfare and the scientific study of affect. (Special Issue: Animal suffering and welfare.)
| Contributor(s):: Fraser, D.
Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect...
Effect of infestation with Psoroptes ovis on the nocturnal rubbing and lying behaviour of housed sheep
| Contributor(s):: Berriatua, E., French, N. P., Broster, C. E., Morgan, K. L., Wall, R.
The relationship between Psoroptes ovis infestation and the nocturnal rubbing and lying behaviour of sheep was examined as part of a longitudinal study of sheep scab. A total of 40 non-infested, scab-naive sheep were divided into six groups of between 6 and 20 individuals and each group was...
Grooming and control of fleas in cats
| Contributor(s):: Eckstein, R. A., Hart, B. L.
Oral grooming is common in cats, as in rodent and bovid species where grooming has been shown to be effective in removing lice and ticks. In Experiment 1, we examined the effectiveness of oral grooming in removing fleas which are the main ectoparasite of cats. Elizabethan collars (E-collars)...
Intake and selection for white clover by grazing lambs in response to gastrointestinal parasitism
| Contributor(s):: Cosgrove, G. P., Niezen, J. H.
A study was conducted at Palmerston North, New Zealand to determine if lambs grazing at pasture would enhance their nutrient intake in response to parasitism, by selecting more white clover from a mixed grass-clover pasture. The trial used a split-plot design with two grass-clover mixtures as...
Motivational trade-offs and potential pain experience in hermit crabs
| Contributor(s):: Appel, M., Elwood, R. W.
One criterion of pain experience is that the emotional response to pain may be traded-off against other motivational requirements. This was tested in hermit crabs, housed in either preferred or unpreferred species of shells, by subjecting their abdomens to electric shocks of gradually increasing...
