  1. Breed and sex differences in the behavioural attributes of specialist search dogs - a questionnaire survey of trainers and handlers

    Contributor(s):: Rooney, N. J., Bradshaw, J. W. S.

    The behavioural characteristics of specialist search dogs were examined using a survey of 244 dog handlers and trainers. The English Springer Spaniel was the most common breed, followed by the Labrador Retriever, cross breeds and the Border Collie. Individuals of these four breeds varied...

  2. Characterisation of sows' postures and posture changes with regard to crushing piglets

    Contributor(s):: Wischner, D., Kemper, N., Stamer, E., Hellbruegge, B., Presuhn, U., Krieter, J.

    The aim of this study was to analyse different behavioural traits of sows to describe posture changes and to determine the influences of these traits on piglet losses. The behaviour of 386 German Landrace sows (with 438 pure-bred litters) was videotaped continuously starting 12 h prepartum until...

  3. Comparison of methods to assess fear of humans in sows

    Contributor(s):: Scott, K., Laws, D. M., Courboulay, V., Meunier-Salaun, M. C., Edwards, S. A.

    The aims of this study were to compare three different methods to assess fear of humans in sows, and identify the most practical and reliable method for on-farm welfare assessment. Fifty-five crossbred sows (Landrace x Large White x Duroc) of different parities and stages of pregnancy were each...

  4. Cross-sucking and gradual weaning of dairy calves

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

    To examine the effect of gradually weaning calves off milk on cross-sucking, and the relationship between cross-sucking and energy intake, 32 Holstein calves were housed in groups of four and allowed 12 L/d of milk until the process of weaning began. The process of weaning was either abrupt at 41...

  5. Dairy cows prefer shade that offers greater protection against solar radiation in summer: shade use, behaviour, and body temperature

    Contributor(s):: Schutz, K. E., Rogers, A. R., Cox, N. R., Tucker, C. B.

    There is considerable evidence that shade is a valuable resource for cattle in summer, but less is known about the important design features of effective shade. The aim of this experiment was to investigate if lactating dairy cows have a preference for shade that offers greater protection against...

  6. Dairy cows trade-off feed quality with proximity to a dominant individual in Y-maze choice tests

    Contributor(s):: Rioja-Lang, F. C., Roberts, D. J., Healy, S. D., Lawrence, A. B., Haskell, M. J.

    In this experiment choice tests were used as a tool to determine how dairy cows perceive their feeding environment with specific emphasis on understanding the challenges that low ranking animals face when forced to feed in the presence of socially dominant cows. It was hypothesised that cows...

  7. Describing the ideal Australian companion dog

    Contributor(s):: King, T., Marston, L. C., Bennett, P. C.

    Dogs have had a long association with humans and are believed to be the first domesticated animal species. Many breeds of dog exist today which vary considerably in physical appearance and temperament. These differences have arisen primarily from selective pressures imposed by humans to create...

  8. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal ("low")) and two...

  9. Effects of age, sex and social isolation on contrafreeloading in red junglefowl ( Gallus gallus ) and White Leghorn fowl

    Contributor(s):: Lindqvist, C., Jensen, P.

    Contrafreeloading (CFL), i.e. choosing to work to obtain food over free food, has been studied in many different species. White Leghorn laying hens selected for high production have a lower extent of CFL compared to their wild ancestor, red junglefowl. We studied the effects of age, sex and...

  10. Effects of social behaviour on the spatial distribution of sheep grazing a complex vegetation mosaic

    Contributor(s):: Sibbald, A. M., Oom, S. P., Hooper, R. J., Anderson, R. M.

    In complex environments, the spatial distribution of preferred food types will be a major factor influencing the distribution of foraging animals. However, in highly social animals, such as sheep, social interactions may modify foraging behaviour and hence influence both where animals feed and...

  11. Environmental influences on the expression of aggressive behaviour in English Cocker Spaniels

    Contributor(s):: Podberscek, A. L., Serpell, J. A.

    A group of low (n=217) and high (n=218) aggression purebred English Cocker Spaniels were compared in relation to demographics and owner interactions. Owners of low aggression dogs were more likely to be older (65 years+) and more attached to their dogs. Dogs in the high aggression group were...

  12. Fear of novel and startling stimuli in domestic dogs

    Contributor(s):: King, T., Hemsworth, P. H., Coleman, G. J.

    Dog aggression to humans is a serious problem and it appears that fear-induced aggression in dogs is often implicated. Furthermore, it has been suggested that novel and startling stimuli may trigger fear-induced aggression. The aim of the present study was to study some possible behavioural and...

  13. Influence of different types of environmental enrichment on the behaviour of finishing pigs in two different housing systems: 3. Hanging toy versus rootable toy of the same material

    Contributor(s):: Scott, K., Taylor, L., Gill, B. P., Edwards, S. A.

    This study aimed to assess the effects of (1) environmental enrichment with either straw bedding or a plastic toy and (2) the way in which the plastic toy was presented on the behaviour of finishing pigs in two different housing systems. One thousand and twenty four (Large White x Landrace) x...

  14. Influence of post-calving regrouping strategy on welfare and performance parameters in dairy heifers

    Contributor(s):: O'Connell, N. E., Wicks, H. C. F., Carson, A. F., McCoy, M. A.

    Thirty-six Holstein Friesian heifers (dairy herd replacements) were assigned to one of three regrouping treatments during the post-calving period. In Treatment 1, heifers were introduced individually to an established group of cows and heifers within 24 h of calving ('Single - day 1'). In...

  15. Influences on the avoidance and approach behaviour of dairy cows towards humans on 35 farms

    Contributor(s):: Waiblinger, S., Menke, C., Folsch, D. W.

    The human-animal relationship is an important issue when assessing animal welfare on farms, but generally accepted and used methods for its practical assessment on dairy farms have been lacking until now. The aim of this study was to validate different farm test of cows reactions towards humans...

  16. Mixed housing of different genetic lines of laying hens negatively affects feather pecking and fear related behaviour

    Contributor(s):: Uitdehaag, K. A., Rodenburg, T. B., Bolhuis, J. E., Decuypere, E., Komen, H.

    Adult laying hens from Rhode Island Red (RIR) origin both express lower levels of feather pecking and lower fear responses towards a novel object than laying hens from White Leghorn (WL) origin. The present study investigated whether mixed housing of RIR and WL laying hens would affect their...

  17. Piglet use of the creep area - effects of breeding value and farrowing environment

    Contributor(s):: Vasdal, G., Andersen, I. L., Pedersen, L. J.

    The objective of this study was to investigate piglet use of the creep area, comparing litters of sows with a high vs. low breeding value for piglet survival in the first 5 days postpartum, that were either housed in crates or individual pens during farrowing and lactation. Seventy-five Yorkshire...

  18. Shyness-boldness predicts performance in working dogs

    Contributor(s):: Svartberg, K.

    This study investigates if there are relationships between personality and performance of dogs (Canis familiaris) in working dog trials. Data from 2655 dogs of the two breeds German Shepherd dog (GSD) and Belgian Tervuren (BT) in Sweden obtained between 1989 and 1997 were used. The breeds were...

  19. Suffering in diseased pigs as expressed by behavioural, clinical and clinical-chemical traits, in a well defined parasite model. (Special Issue: Animal suffering and welfare.)

    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...

  20. The effect of breed and housing system on dairy cow feeding and lying behaviour

    Contributor(s):: O'Driscoll, K., Boyle, L., Hanlon, A.

    In Ireland there is growing interest in managing dairy cows on out-wintering pads (OWPs) during the winter, as a low cost alternative to housing indoors. This study investigated feeding and lying behaviour of two breeds of dairy cow (Holstein-Friesian and Norwegian Red) at pasture (PAS) and in...
