A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins ( Saguinus labiatus )
Contributor(s):: Owen, Y., Amory, J. R.
Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or veterinary practices is accepted as a...

A pilot study to develop an assessment tool for sheep welfare after long journey transport
Contributor(s):: Messori, S., Sossidou, E., Buonanno, M., Mounaix, B., Barnard, S., Vousdouka, V., Villa, P. dalla, Roest, K. de, Spoolder, H.
Sheep transport within Europe involves 9.5 million animals yearly, 63% of which travel over long journeys (>8 h). Livestock transport, particularly over long journeys, gives rise to concern about the welfare of transported animals. The European Commission stimulates the development of...
A preliminary study investigating the physical welfare and welfare code compliance for tethered and free-ranging horses on common land in South Wales

A preliminary study of behaviour-based indicators of pain in cats
Contributor(s):: Waran, N., Best, L., Williams, V., Salinsky, J., Dale, A., Clarke, N.
The aim of this preliminary study was to identify key behavioural indicators of pain in cats. The behaviour of cats before and after ovariohysterectomy was analysed using a detailed behavioural ethogram. A comparison of behaviours between cats given pre-operative analgesia only and cats given...
A short note on effects of exposure to a novel stimulus (umbrella) on behaviour and percentage of eye-white in cows
Contributor(s):: Sandem, A. I., Janczak, A. M., Braastad, B. O.
The present experiment aimed at investigating the sensitivity of "eye-white percentage" as a dynamic indicator of fear in 16 dairy cows and describing the startle response provoked by sudden exposure to an unfamiliar suddenly opened umbrella. Sudden opening of the umbrella 0-2 m in front of cows...
A tool for the evaluation of slaughter horse welfare during unloading
Contributor(s):: Messori, S., Visser, E. K., Buonanno, M., Ferrari, P., Barnard, S., Borciani, M., Ferri, N.
This study aimed to develop a scientific and practical tool to be used to assess horse welfare after commercial transport over long journeys. A set of physical, behavioural and environmental measures was selected, covering welfare aspects of both transport and unloading procedures. The protocol...
Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective
Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.
Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...
Agreement between different sleep states and behaviour indicators in dairy cows
Contributor(s):: Ternman, E., Pastell, M., Agenas, S., Strasser, C., Winckler, C., Nielsen, P. P., Hanninen, L.
Conclusive data regarding behavioural indicators of different sleep states in adult dairy cows are lacking, i.e. agreement between behavioural indicators of sleep and corresponding electrophysiological measures. Behavioural estimates for quantifying total sleep time in calves have been developed,...
An assessment of laboratory mouse welfare in UK animal units
Contributor(s):: Leach, M. C., Main, D. C. J.
The welfare of conventional stock laboratory mice has been assessed in 46 UK animal units using an expert-defined welfare assessment protocol containing 119 measures of mouse welfare. These were recorded using a questionnaire and observations made during a one-day visit to each unit. The standard...
An epidemiological approach to welfare research in zoos: the Elephant Welfare Project
Contributor(s):: Carlstead, K., Mench, J. A., Meehan, C., Brown, J. L.
Multi-institutional studies of welfare have proven to be valuable in zoos but are hampered by limited sample sizes and difficulty in evaluating more than just a few welfare indicators. To more clearly understand how interactions of husbandry factors influence the interrelationships among welfare...
An experience sampling approach to investigating associations between pet presence and indicators of psychological wellbeing and mood in older Australians
Contributor(s):: Bennett, P. C., Trigg, J. L., Godber, T., Brown, C.
In this study we examined associations between pet ownership and presence and indicators of psychological wellbeing in older Australians, using an innovative, experience sampling methodology and a community-living sample of 68 adults, including 41 pet owners, all aged over 65 years. In response...
Animal housing and welfare: effects of housing conditions on body weight and cortisol in a medium-sized rodent ( Cavia aperea)
Contributor(s):: Schumann, K., Guenther, A., Jewgenow, K., Trillmich, F.
Rodents are the most abundant experimental nonhuman animals and are commonly studied under standard laboratory housing conditions. As housing conditions affect animals' physiology and behavior, this study investigated the effects of indoor and outdoor housing conditions on body weight and...
Animal-based parameters are no panacea for on-farm monitoring of animal welfare
Contributor(s):: Bracke, M. B. M.
On-farm monitoring of animal welfare is an important, present-day objective in animal welfare science. Scientists tend to focus exclusively on animal-based parameters, possibly because using environment-based parameters could be begging the question why welfare has been affected and because...
Are severely depressed suckling pigs resistant to gas euthanasia?
Contributor(s):: Sadler, L. J., Karriker, L. A., Schwartz, K. J., Johnson, A. K., Widowski, T. M., Wang, C., Sutherland, M. A., Millman, S. T.
Severely depressed pigs exhibit differences in a number of important parameters that may affect gas euthanasia, including decreased respiration rate and tidal volume. Hence, the objectives of this study were to assess the efficacy and animal welfare implications of gas euthanasia of suckling pigs...
Are the effects of enrichment due to the presence of multiple items or a particular item in the cages of laboratory rat?
Contributor(s):: Abou-Ismail, U. A.
Although the effects of environmental enrichment on laboratory rodents have been extensively described, it is not yet known whether these effects were simply due to the presence of multiple items in the cage or due solely to the presence of a particular item. This experiment was therefore carried...
Assessing animal welfare in a strictly synchronous production system: the mink case
Contributor(s):: Moller, S. H., Hansen, S. W., Sorensen, J. T.
Most on-farm welfare assessment systems have been developed for use in dairy and pig farms. These production systems are non-synchronous, in the sense that the same processes occur continuously throughout the year. Animal welfare during most or all phases of production may therefore be assessed...
Assessing quality of life in companion and kennelled dogs: a critical review
Contributor(s):: Hewson, C. J., Hiby, E. F., Bradshaw, J. W. S.
Two distinct approaches have emerged for the assessment of quality of life (QoL) and welfare in domestic dogs. One approach, which has so far been applied only to companion dogs, is derived from proxy assessment of QoL in human beings, with the owner or veterinarian acting as the proxy. Because...
Assessing the effects of a chronic stressor, stocking density, on welfare indicators of juvenile African catfish, Clarias gariepinus Burchell
Contributor(s):: Nieuwegiessen, P. G. van de, Boerlage, A. S., Verreth, J. A. J., Schrama, J. W.
Fish welfare is an area of increasing interest and stocking densities used in commercial aquaculture have been highlighted as a subject of specific welfare concern. The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...
