Protocol for expert report on animal welfare in case of companion animal cruelty suspicion
Contributor(s):: Hammerschmidt, J., Molento, C. F. M.
Animal welfare expert reports may support court decisions when animal abuse or maltreatment is suspected. The objective of this work is to adapt animal welfare assessment protocols to identify companion animal abuse. The proposed protocol includes four indicator categories: nutritional, comfort,...
Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae
Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.
Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...

A note on the effect of controlling stable flies ( Stomxys calcitrans ) in the resting activity and pen distribution of dairy cows
Contributor(s):: Vitela, I., Cruz-Vazquez, C., Orihuela, A.
This study investigated the effect of controlling stable flies (Stomoxys calcitrans) on the number of dairy cows lying down and their pen distribution. The study randomly assigned 80 Holstein cows to 1 of 2 groups. The treated group (T) included cows individually sprayed with insecticide when...

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...
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,...
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...
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,...
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)...
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...
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 understand the role that...
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...
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...
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...
Pain and stress in crustaceans? (Special Issue: Animal suffering and welfare.)
Contributor(s):: Elwood, R. W., Barr, S., Patterson, L.
We consider evidence that crustaceans might experience pain and stress in ways that are analogous to those of vertebrates. Various criteria are applied that might indicate a potential for pain experience: (1) a suitable central nervous system and receptors, (2) avoidance learning, (3) protective...
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)...
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...
Face-fly pest intensity, fly-avoidance behavior (bunching) and grazing time in Holstein heifers
Contributor(s):: Schmidtmann, E. T., Valla, M. E.
In field studies in New York State in 1978-79, the relationship between feeding by adults of Musca autumnalis Deg., and fly-avoidance behaviour (bunching) and grazing time of heifers was examined in herds that were either exposed to the ambient pest intensity levels or treated with permethrin...
