A comparison of inferential analysis methods for multilevel studies: Implications for drawing conclusions in animal welfare science
Contributor(s):: Stevens, Kara N., Asher, Lucy, Griffin, Kym, Friel, Mary, O'Connell, Niamh, Collins, Lisa M.
Investigations comparing the behaviour and welfare of animals in different environments have led to mixed and often conflicting results. These could arise from genuine differences in welfare, poor validity of indicators, low statistical power, publication bias, or inappropriate statistical...
Effects of guest feeding programs on captive giraffe behavior
Contributor(s):: Orban, D. A., Siegford, J. M., Snider, R. J.
Zoological institutions develop human-animal interaction opportunities for visitors to advance missions of conservation, education, and recreation; however, the animal welfare implications largely have yet to be evaluated. This behavioral study was the first to quantify impacts of guest feeding...
Influences on the avoidance and approach behaviour of dairy goats towards an unfamiliar human - an on-farm study
Contributor(s):: Mersmann, D., Schmied-Wagner, C., Nordmann, E., Graml, C., Waiblinger, S.
The human-animal relationship (HAR) is an important factor for successful animal husbandry and animal welfare. Thus, the HAR is included in on-farm assessments to evaluate overall welfare. For dairy goats, validated tests to assess the HAR are lacking. The aim of the present study was to evaluate...
The associations between animal-based welfare measures and the presence of indicators of food safety in finishing pigs
Contributor(s):: Alpigiani, I., Bacci, C., Keeling, L. J., Salman, M. D., Brindani, F., Pongolini, S., Hitchens, P. L., Bonardi, S.
Stressful housing and management practices affect animals, potentially increasing their receptiveness to pathogens. Since some pathogens do not lead to clinical signs of sickness, subclinical pigs could enter the food-chain, contaminating carcases and offal at slaughter, representing a threat to...

On-farm evaluation of the Salmon Welfare Index Model (SWIM 1.0): theoretical and practical considerations
Contributor(s):: Folkedal, O., Pettersen, J. M., Bracke, M., Stien, L. H., Nilsson, J., Martins, C., Breck, O., Midtlyng, P. J., Kristiansen, T.
The present study investigated the operational feasibility of the recently developed Salmon Welfare Index Model (SWIM 1.0) designed for Atlantic salmon ( Salmo salar L) in production cages. Ten salmon farms containing spring smolts were visited twice, first between May and June the first year in...
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...
Evaluation of a novel rodenticide: welfare assessment of fatal methaemoglobinaemia in adult rats ( Rattus norvegicus)
Contributor(s):: Gibson, T. J., Quy, R. J., Eason, C. T., Gregory, N. G.
This study assessed the welfare of rats ( Rattus norvegicus) poisoned with a lethal dose of the methaemoglobin (MetHb) inducing compound para-aminovalerophenone (PAVP). Twenty rats were orally gavaged with either PAVP (treated) or the vehicle only (control). Spontaneous and evoked behaviours were...
Stereotypic mice are aggressed by their cage-mates, and tend to be poor demonstrators in social learning tasks
Contributor(s):: Harper, L., Choleris, E., Ervin, K., Fureix, C., Reynolds, K., Walker, M., Mason, G.
Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social...
Are we ignoring neutral and negative human-animal relationships in zoos?

An observational study of the effects of therapeutic hoof blocks on the locomotion, behavior, and production of healthy dairy cattle
Contributor(s):: Cutler, J. H., Shearer, J. K., Kelton, D. F., Cramer, G., Gorden, P. J., Millman, S. T.
Therapeutic hoof blocks have been recommended for treatment of sole ulcers in dairy cattle; however, they are underutilized in the industry. Twenty Holstein cows were randomly assigned to receive a wooden hoof block applied to the left hind leg ( n=5), to the right hind leg ( n=5), or no hoof...
Factors affecting penetrating captive bolt gun performance
Contributor(s):: Gibson, T. J., Mason, C. W., Spence, J. Y., Barker, H., Gregory, N. G.
Captive bolt stunning is used for rendering livestock insensible at slaughter. The mechanical factors relating to performance of 6 penetrating captive bolt gun (CBG) models were examined. The Matador Super Securit 3000 and the .25 Cash Euro Stunner had the highest kinetic energy values (443 J and...
The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment
Contributor(s):: Rehnberg, L. K., Robert, K. A., Watson, S. J., Peters, R. A.
Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these...
Age, breed designation, coat color, and coat pattern influenced the length of stay of cats at a no-kill shelter
Contributor(s):: Brown, W. P., Morgan, K. T.
Adoption records from the Tompkins County Society for the Prevention of Cruelty to Animals, an open-admission, no-kill shelter in New York State, were examined to determine if various physical attributes influenced the length of stay (LOS) of cats and kittens. Similar reports from other no-kill...
Application of the Welfare Quality animal welfare assessment system in Finnish pig production, Part II: Associations between animal-based and environmental measures of welfare
Contributor(s):: Munsterhjelm, C., Heinonen, M., Valros, A.
This study aimed to establish associations between the environment and animal-based measures of welfare collected on 158 Finnish farms according to the Welfare Quality systems for pigs. The data consisted of 95 welfare assessments in fattening pigs and 103 in sows, including suckling piglets....
Human-animal interactions (HAI), which may lead to human-animal relationships (HAR), may be positive, neutral, or negative in nature. Zoo studies show that visitors may be stressful, may have no effect, or may be enriching. There is also evidence that good HARs set up between animals and their...
Comparison of the behaviour of piglets raised in an artificial rearing system or reared by the sow
Contributor(s):: Rzezniczek, M., Gygax, L., Wechsler, B., Weber, R.
Over the last 15 years, rising sow fertility has led to a considerable increase in litter size. As a consequence, the number of live born piglets may outnumber the number of functional teats, and surplus piglets are removed from the sow at the age of 3-6 days and fed with artificial milk. The...
Effects of sounds of different quality on the behaviour and heart beat parameters of goats
Contributor(s):: Johns, J., Patt, A., Hillmann, E.
In alpine regions, bells are used to relocate free-ranging grazers like cows and goats. Considering that goats have a well-developed hearing capacity, sounds (e.g. a chime of a bell) may act as stressors depending on their characteristics. The aim of this study was to test whether a non-uniform...
Refinement of welfare through development of a quantitative system for assessment of lifetime experience
Contributor(s):: Wolfensohn, S., Sharpe, S., Hall, I., Lawrence, S., Kitchen, S., Dennis, M.
This paper proposes a system that uses intrinsic study data to provide a clear visualisation of the stresses involved during the animal's life history that can be applied to all types of studies, even those not requiring invasive techniques. Thus, it provides an opportunity for researchers to...
