  1. Gangs of piglets: Welfare and growth of imprinted and guided weaners

    Contributor(s):: Mesarec, Nikolina, Povše, Maja Prevolnik, Škorjanc, Dejan, Skok, Janko

    Weaning stress accompanied by outburst of aggression is a critical point in pig production as it compromises piglets’ welfare and leads to poor growth rate and health problems. Therefore, a weaning methods to smoothen the lactation–weaning transition are of great importance. In the present study...

  2. Foster parenting, human imprinting and conventional handling affects survival and early weight of ostrich chicks

    Full-text: Available

    | Contributor(s):: MD Wang, SWP Cloete, K Dzama, M Bonato, IA Malecki

    The effects of human imprinting and foster parenting by adult ostriches on the survival and growth performance of ostrich chicks were compared to conventional chick-rearing practices in two separate experiments. In the first experiment, the growth rate and survival of chicks imprinted onto...

  3. Development of early foraging behaviour of domestic chicks in varying social contexts

    | Contributor(s):: Gajdon, G. K., Mundwiler, B., Stauffacher, M.

    Two aspects of foraging development might be crucial to learning in precocial chicks: what food particles look like and what food sites look like. Previous research indicates that there are innate dispositions for particle preferences and for preferring the type of food sites experienced between...

  4. 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...

  5. Dairy cows' fear of people: social learning, milk yield and behaviour at milking

    | Contributor(s):: Munksgaard, L., Passille, A. M. de, Rushen, J., Herskin, M. S., Kristensen, A. M.

    We examined the effects of the presence of an unfamiliar, a gentle or an aversive handler during milking on behaviour and milk yield, and whether cows can learn to approach or avoid a handler by observing the neighbouring cow's responses. In Experiment 1, Danish Friesian cows (n=16) were treated...

  6. How do miniature pigs discriminate between people? Discrimination between people wearing coveralls of the same colour

    | Contributor(s):: Koba, Y., Tanida, H.

    Seven experiments were conducted on 4 miniature pigs to determine: (1) whether the pigs can discriminate between people wearing the same coloured clothing and (2) what cues they rely on if they could discriminate. For 2 weeks before the experiments began, the pigs were conditioned in a Y-maze to...

  7. Influence of prior exposure to wood shavings on feather pecking, dustbathing and foraging in adult laying hens

    | Contributor(s):: Nicol, C. J., Lindberg, A. C., Phillips, A. J., Pope, S. J., Wilkins, L. J., Green, L. E.

    It has been proposed that chicks acquire substrate preferences during an early 'sensitive' period. If a suitable substrate is absent during this period birds may develop alternative preferences for pecking at feathers. The aim of this study was to examine whether early substrate exposure has...

  8. 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...

  9. 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...

  10. The imprints created by cattle grazing short sequences of bites on continuous alfalfa swards

    | Contributor(s):: Ungar, E. D., Griffiths, W. M.

    Grazing by cattle on the scale of a single feeding station was studied to determine the patterns of defoliation and bite dimensions in short bite sequences. The sward was a continuous and homogeneous expanse of alfalfa without any imposed patchiness of structure. Treatments were bite sequences of...

  11. Physical contact while handling is not necessary to reduce fearfulness in the rabbit

    | Contributor(s):: Ducs, A., Bilko, A., Altbacker, V.

    Rabbits handled around nursing time during the first week after birth show reduced fear response toward humans. Our earlier attempt to reduce the duration of daily treatment necessary to achieve this effect showed that even a minimal human contact, characteristic of animal caretaking in intensive...

  12. Imprinting of farm animals on human beings

    | Contributor(s):: Sambraus, Hans H., Sambraus, Dorte

  13. Pecking: another measurement for filial attachment in group-reared domestic fowl chicks

    | Contributor(s):: Gvaryahu, G., Snapir, N., Robinzon, B.

    Different types of attachment measurements and pecking behaviour were investigated in group-reared domestic chicks imprinted to a silent imprinting object. Immediately upon arriving from the hatchery, groups of heavy strain chicks were imprinted to a coloured foam rubber ball for 72 h. The bond...

  14. Early experience and behavioural development in foals. (EAAP Publication No.122)

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

    The effect of breeding and farm management practices, handling and other environmental factors on the behavioural development of foals are discussed.
