  1. Calf mortality in semi-domestic reindeer ( Rangifer tarandus) in a Scottish herd: the impact of maternal age and individual differences between cow

    Contributor(s):: Jorgensen, M. W., Jarvis, S., Brewer, M. J., Goddard, P. J.

    High calf mortality rate is a significant problem facing semi-domestic reindeer ( Rangifer tarandus) production around the world. Mortality rates, commonly due to predation, can range from 5 to 70%, which constitutes a great welfare concern. This study examined the influence of quantifiable...

  2. Consistency in European seabass coping styles: a life-history approach

    Contributor(s):: Ferrari, S., Millot, S., Leguay, D., Chatain, B., Begout, M. L.

    Recent years have seen a growth of interest in the consistent differences in individual behaviour over time and contexts constituting the so-called "individual coping styles". An understanding of this inter-individual variation is essential to improve our knowledge of the adaptive value of...

  3. Consistent individual differences in the behavioural responsiveness of adult male cuttlefish ( Sepia officinalis)

    Contributor(s):: Carere, C., Grignani, G., Bonanni, R., Gala, M. della, Carlini, A., Angeletti, D., Cimmaruta, R., Nascetti, G., Mather, J. A.

    Consistent individual differences in clusters of behaviour (animal personalities) are being increasingly recognized by researchers of different disciplines, but studies on invertebrates are still scanty. In order to test for the presence of personality-like individual profiles we assessed the...

  5. Identifying environmental and management factors that may be associated with the quality of life of kennelled dogs ( Canis familiaris)

    Contributor(s):: Kiddie, J., Collins, L.

    This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were allocated to one of the four treatment groups, all of which had a...

  6. 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...

  7. Potential welfare impacts of kill-trapping European moles ( Talpa europaea) using scissor traps and duffus traps: a post mortem examination study

    Contributor(s):: Baker, S. E., Shaw, R. F., Atkinson, R. P. D., West, P., Macdonald, D. W.

    Moles are widely trapped as pests on farms and amenity land in Britain. Spring traps for killing mammals generally require welfare approval in the UK, but mole traps are exempt. Previous research demonstrated wide variation in the mechanical performance of mole traps. In this context, we aimed to...

  8. What do calves choose to eat and how do preferences affect behaviour?

    Contributor(s):: Webb, L. E., Engel, B., Berends, H., Reenen, C. G. van, Gerrits, W. J. J., Boer, I. J. M. de, Bokkers, E. A. M.

    Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the 'average calf'. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...

  9. Mapping farm animal welfare education at university level in Europe

    Contributor(s):: Illmann, G., Keeling, L., Melisova, M., Simeckova, M., Ilieski, V., Winckler, C., Kost'al, L., Meunier-Salaun, M. C., Mihina, S., Spoolder, H., Fthenakis, G., Sarova, R., Spinka, M.

    The aim of this study was to map farm animal welfare university education in an enlarged Europe with emphasis on identifying existing differences and gaps. Information on 210 courses dealing with farm animal welfare from 98 universities in 26 European countries were obtained. Statistical analysis...

  10. Relationships between pig welfare, productivity and farmer disposition

    Contributor(s):: Jaaskelainen, T., Kauppinen, T., Vesala, K. M., Valros, A.

    The aim of this study was, firstly, to investigate the connection between on-farm assessed welfare scores and production parameters for sows, and secondly, to examine how farmers perceive the connection between their disposition, animal welfare and productivity. We assessed environmental and...

  11. Sociality motivation and anthropomorphic thinking about pets

    Contributor(s):: Paul, E. S., Moore, A., McAinsh, P., Symonds, E., McCune, S., Bradshaw, J. W. S.

    Sociality motivation, the need to feel socially connected with others, has been proposed as an important determinant of individual variation in anthropomorphic thinking. Specifically, it has been suggested that people who are socially isolated or disconnected will tend to infer more human-like...

  12. Welfare Quality parameters do not always reflect hen behaviour across the lay cycle in non-cage laying hens

    Contributor(s):: Daigle, C., Siegford, J.

    The integration of outcome-based measurements to animal welfare assessment programmes can provide a new perspective on the individual animal's experience. Identifying variability in individual experiences can facilitate understanding of animals at the periphery of the welfare spectrum, compared...

  13. Is that dog a pit bull? A cross-country comparison of perceptions of shelter workers regarding breed identification

    Contributor(s):: Hoffman, C. L., Harrison, N., Wolff, L., Westgarth, C.

    Bull breeds are commonly kept as companion animals, but the pit bull terrier is restricted by breed-specific legislation (BSL) in parts of the United States and throughout the United Kingdom. Shelter workers must decide which breed(s) a dog is. This decision may influence the dog's fate,...

  14. Variations of some physiological and immunological parameters in Siberian sturgeon ( Acipenser baerii, Brandt, 1869) subjected to an acute stressor

    Contributor(s):: Eslamloo, K., Falahatkar, B.

  16. Behaviour epigenetics - the connection between environment, stress and welfare

    Contributor(s):: Jensen, P.

    Epigenetics refers to chemical modifications of DNA, which do not change the base-pair sequence. This involves, for example, methylation of cytosine and different alterations in histone chemistry. Such modifications affect how genes are expressed and can occur as a response to stress, mediated by...

  17. Dairy calves' adaptation to group housing with automated feeders

    Contributor(s):: Fujiwara, M., Rushen, J., Passille, A. M. de

    Group housing of dairy calves with automated milk feeders has likely welfare and labour saving advantages but delays in the calves adapting to the feeding system may reduce these advantages. We examined factors that influence calves' adaptation to the feeders. In Exp. 1, 77 Holstein calves were...

This study aimed to develop a validated scoring system to assess the quality of life of dogs kennelled in rehoming centres. Objective animal-based...

  19. Instantaneous intake rate of free-grazing cattle as affected by herbage characteristics in heterogeneous tropical agro-pastoral landscapes

    Contributor(s):: Chirat, G., Groot, J. C. J., Messad, S., Bocquier, F., Ickowicz, A.

    Numerous territories of Sub-Saharan Africa are composed of a mosaic of very different landscape units: cropland, forest, and savannah. This spatial, but also temporal heterogeneity leads to complexity in the analysis of cattle intake behaviour. The instantaneous intake rate (IIR) is generally...

  20. Resources and their distribution can influence social behaviour at translocation sites: lessons from a lizard

    Contributor(s):: Ebrahimi, M., Bull, C. M.

    In a translocation programme, social interactions among released individuals can influence the tendency for the individuals to remain at the site where they have been released. Dispersal away from the region of release may reduce the success of a translocation because dispersing individuals may...
