  2. Behavioural changes induced by handling at different timeframes in Lusitano yearling horses

    Contributor(s):: Pereira-Figueiredo, Inês, Costa, Helena, Carro, Juan, Stilwell, George, Rosa, Ilda

    Recent interest has focused on the advantage of intensely handling young horses, as a good tool for improving emotional reactivity and thence trainability. Its effectiveness remains controversial, suggesting it might depend on the right timeframe to do so. The present study aimed to evaluate the...

  3. Evaluation of operant learning in young foals using target training

    Contributor(s):: Martinez de Andino, Elena V., McDonnell, Sue M.

    The primary purpose of this study was to characterize operant learning performance of young foals. For each of 26 foals, aged 6–20 weeks, learning performance was quantitatively evaluated in a single brief training trial using a standard operant conditioning task and paradigm analogous to those...

  4. A two-stage method to approach weaning stress in horses using a physical barrier to prevent nursing

    Contributor(s):: Merkies, Katrina, DuBois, Cordelie, Marshall, Kaitlyn, Parois, Severine, Graham, Laura, Haley, Derek

    Many domestic horses are weaned through abrupt physical separation of the foal and mare. Deviations from normal behaviours testify that this abrupt method has an adverse effect on the well-being of both mares and foals. To reduce negative changes in behaviour and physiology induced by weaning, a...

  5. Foal and Mare Behavior Changes during Repeated Human-Animal Interactions in the First Two Weeks after Foaling

    Contributor(s):: Elizabeth Baehl, Breanna Sheahan, Eleonora Po

    This study is important to the equine research field to demonstrate if handling neonatal foals and mares who recently foaled is invasive and may change how the foals and mares will behave around humans. The data show the effects of repeated blood draws and frequent handling on the foals and...

  6. Health problems and risk factors associated with long haul transport of horses in Australia

    Full-text: Available

    | Contributor(s):: Padalino, B., Hall, E., Raidal, S., Celi, P., Knight, P., Jeffcott, L., Muscatello, G.

    Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study...

  7. Transport of horses for slaughter in Iceland

    | Contributor(s):: Roy, R. C., Cockram, M. S., Dohoo, I. R., Ragnarsson, S.

    There is interest in the transportation of horses ( Equus caballus) to slaughter and a need to assess the welfare implications of this practice. Forty-six loads of 7-35 horses transported for 0.33 to 3.10 h to a slaughter plant in Iceland were studied. Adults and foals were transported together...

  8. Events around weaning in semi-feral and stable-reared Konik polski foals: evaluation of short-term physiological and behavioural responses

    | Contributor(s):: Gorecka-Bruzda, A., Suwala, M., Palme, R., Jaworski, Z., Jastrzebska, E., Boron, M., Jezierski, T.

    The annual weaning, stabling and subsequent sale of semi-feral Konik polski foals born in forest reserves ensure a stable population of free-roaming Konik polski horses. However, welfare concerns regarding the maternal and herd separation of young horses, manipulation by humans, transportation...

  9. Variations in the timing of reinforcement as a training technique for foals ( Equus caballus )

    | Contributor(s):: Warren-Smith, A. K., McLean, A. N., Nicol, H. I., McGreevy, P. D.

    Horses are used worldwide for a range of activities. Their usefulness and welfare in these pursuits are strongly influenced by their trainability, which may in turn be influenced by learning ability. Handling and riding horses can expose both handler and horse to a considerable risk of injury....

  10. Absence of effects from immunocontraception on seasonal birth patterns and foal survival among barrier island wild horses

    | Contributor(s):: Kirkpatrick, J. F., Turner, A.

    Despite a large body of safety data, concern exists that porcine zonae pellucidae (PZP) immunocontraception - used to manage wild horse populations - may cause out-of-season births with resulting foal mortality. Our study at Assateague, Maryland indicated the effects of immunocontraception on...

  11. Técnica de imprinting, sociabilización y manejo intensivo temprano en el potrillo

    | Contributor(s):: Francisco González del Pino, Fernando Escalante, Oscar R. Wilde

    El imprinting es el arte por el cual una persona se “introduce” a un animallactante como un individuo más de su propia especie, realizando unmanejo natural del potrillo en el momento del nacimiento y durante losdías subsiguientes, modificando su personalidad. Este “aprendizaje”ocurre únicamente...

  12. Flight distance and avoidance score in Thoroughbred foals and yearlings and the relationship with handling frequency in the young ages

    | Contributor(s):: Masuda, T., Takakura, A., Kobayashi, S.

    Flight and avoidance reactions from human were examined using 168 postweaning Thoroughbred foals in 22 breeding farms. Further 114 yearlings of 168 foals were tested in the following summer. The foal handlings by the stabler were asked in questionnaire. The relationship between the behavioural...

  13. Are 6-month-old foals sensitive to dam's influence?

    | Contributor(s):: Henry, S., Briefer, S., Richard-Yris, M. A., Hausberger, M.

  14. Aggression and social spacing in light horse ( Equus caballus ) mares and foals

    | Contributor(s):: Weeks, J. W., Crowell-Davis, S. L., Caudle, A. B., Heusner, G. L.

    Aggression and social spacing were studied in 14 light horse mares and their foals living at pasture. Focal samples were collected on each mare-foal dyad for 6 to 10.5 h from 2 months of foal age until weaning at approximately 4 months of age. Observations on foals continued until approximately 6...

  15. Neonatal foal handling

    | Contributor(s):: Simpson, B. S.

    Recent interest has focused on the advantage of intensively handling young foals as a means of producing more tractable horses, accustomed to humans and receptive to training. To date, the effect of this intensive handling, dubbed imprint training in the popular literature, is not tested. The...

  16. Preliminary study of the development of the Flehmen response in Equus caballus

    | Contributor(s):: Weeks, J. W., Crowell-Davis, S. L., Heusner, G.

    The flehmen response is commonly seen in most ungulates as well as in several other species (e.g. felids). The behaviour is most often thought to be part of the sexual behavioural repertoire of males. One reigning hypothesis suggests that this behaviour allows the male to determine the oestrous...

  17. Quantitative and qualitative assessment of the response of foals to the presence of an unfamiliar human

    | Contributor(s):: Minero, M., Tosi, M. V., Canali, E., Wemelsfelder, F.

    This work aimed to apply a combined qualitative and quantitative approach to the interpretation of an on-farm behaviour test for horses, and to examine whether 1 month of handling would affect the response of yearlings to an unfamiliar stationary human in their home environment. Throughout a...

  18. Survey of breeders' management of horses in Europe, North America and Australia: comparison of factors associated with the development of abnormal behaviour

    | Contributor(s):: Parker, M., Goodwin, D., Redhead, E. S.

    An online survey of domestic horse breeders in the USA, UK, Australia, Canada and mainland Europe was carried out in order to examine management risk factors associated with the development of abnormal behaviour patterns. One hundred and forty breeders responded, and epidemiological results...

  19. The effects of early training sessions on the reactions of foals at 1, 2, and 3 months of age

    | Contributor(s):: Williams, J. L., Friend, T. H., Toscano, M. J., Collins, M. N., Sisto-Burt, A., Nevill, C. H.

    An early training procedure commonly termed "foal imprint training" is widely promoted in the horse industry. However, there have been no published scientific investigations of its efficacy. This study determined the effects of a training procedure on foals and their reaction to stimuli used in...

  20. Effects of handling on behaviour and heart rate in Konik horses: comparison of stable and forest reared youngstock

    | Contributor(s):: Jezierski, T., Jaworski, Z., Gorecka, A.

    30 foals and young Konik horses born in 3 consecutive years and reared up to weaning, either in a forest reserve (R) or conventional stable (S), were compared with respect to behavioural reactions and heart rate (HR) during handling manipulations. The foals were randomly allocated within sex and...
