  1. A note on the consistency and specificity of lambs' responses to a stockperson and to their photograph in an arena test

    Contributor(s):: Tallet, C., Veissier, I., Boivin, X.

    Understanding how farm animals perceive their stockperson is a major challenge, especially for artificially reared animals which are known to show strong attraction to humans. Replacing the stockperson by its photograph in an arena test could be a useful method for standardising human stimuli....

  2. A note on the influence of visual conspecific contact on the behaviour of sheltered dogs

    Contributor(s):: Wells, D. L., Hepper, P. G.

    The effects of visual contact with other dogs on the behaviour of dogs housed in a rescue shelter were examined. 407 dogs were studied: 212 dogs were housed in cages that allowed for visual contact with dogs in opposite pens; 195 dogs were deprived of visual contact with other dogs by being...

  3. Exploration as an indicator of good welfare in beef bulls: an attempt to develop a test for on-farm assessment

    Contributor(s):: Westerath, H. S., Laister, S., Winckler, C., Knierim, U.

    Exploration appears to be carried out for its own purpose due to being self-rewarding. Furthermore, it increases environmental certainty with the effect of increased predictability and control of the environment. We, therefore, supposed that exploratory behaviour is associated with positive...

  4. Genital stimulation modifies behavior towards amniotic fluid in estrous ewes

    Contributor(s):: Rubianes, E.

    25 multiparous Corriedale ewes were studied; 7 were anoestrous (control group), 9 were in oestrus and 9, also in oestrus, received 5 min of genital stimulation before testing by simultaneous exposure for 4 min to 2 troughs of feed, 1 dampened with water and the other dampened with amniotic fluid...

  5. Stroking of different body regions by a human: effects on behaviour and heart rate of dairy cows

    Contributor(s):: Schmied, C., Waiblinger, S., Scharl, T., Leisch, F., Boivin, X.

    From observations of intra-specific social grooming in cattle and studies on human stroking in other species, we hypothesised that cows' reactions to human stroking differ depending on the body regions being stroked. Moreover, we tested, whether cows 'reactions to stroking change with the...

  6. A preliminary study into the effectiveness of stroboscopic light as an aversive stimulus for fish

    Contributor(s):: Mesquita, F. de O., Godinho, H. P., Azevedo, P. G. de, Young, R. J.

    To reduce fish mortality in nature it is often necessary to expel individuals from areas modified by humans (e.g., dams) where they could be injured or killed. We tested the effectiveness of stroboscopic light as an aversive stimulus for zebrafish (Danio rerio) in captivity. We used six groups of...

  7. Does drinking milk stimulate sucking in young calves?

    Contributor(s):: Passille, A. M. B. de, Metz, J. H. M., Mekking, P., Wiepkema, P. R.

    To examine the motivation of non-nutritive sucking by calves, a series of tests was conducted on calves that were fed milk replacer by bucket and allowed to suck on a dry artificial teat. After the morning and afternoon meals, the calves sucked the teat for 4-6 min while they sucked it for less...

  8. Sexual stimulation in male sheep and goats

    Contributor(s):: Price, E. O., Borgwardt, R., Orihuela, A., Dally, M. R.

    Previous research has shown that the sexual performance of male goats is enhanced by viewing the mating activities of other males prior to being placed with sexually receptive females. This same experience has no effect on the sexual performance of male sheep. In this experiment, 14 male goats...

  9. The effect of environmental stimulation on the development of behaviour in pigs

    Contributor(s):: Petersen, V., Simonsen, H. B., Lawson, L. G.

    16 litters were reared in barren or enriched environments from birth to slaughter. Enriched pens contained straw, logs and branches, whereas barren pens contained no floor materials or objects. Piglets were weaned at 5 weeks of age. Behaviour was monitored during weeks 4, 7 and 18. Pigs in the...

  10. A new approach to overcoming a yearling Holstein bull's complete lack of motivation to mounting

    Contributor(s):: Foote, R. H., Presicce, G. A., Brockett, C. C.

    A young Holstein bull, selected for semen evaluation, was presented with a variety of sexual stimuli in an attempt to induce it to mount teaser animals and serve an artificial vagina. The bull was tested on 25 occasions and was scheduled for slaughter at 17 months of age because of a total...

  11. Habituation and extinction in an approach-avoidance test: an example with sheep

    Contributor(s):: Erhard, H. W., Elston, D. A., Davidson, G. C.

    During a behavioural test, the test animal's perception of the test situation may change, e.g. as a result of habituation. This change can occur within a test or between repetitions of a test. It is particularly important in the arena test because in an approach-avoidance situation, the negative...

  12. Sound stimuli to enhance ingestive behaviour of young turkeys

    Contributor(s):: Bate, L. A.

    A study was conducted to establish whether auditory stimulation in the form of pre-taped maternal vocalizations would influence initial feeding behaviour in newly hatched poults. For the purposes of the study control birds (Group C) were raised under simulated commercial conditions. Other birds...

  13. The influence of olfactory stimulation on the behaviour of cats housed in a rescue shelter

    Contributor(s):: Ellis, S. L. H., Wells, D. L.

    A wide variety of feline species have been shown to gain welfare benefits from the introduction of olfactory stimuli to the captive environment. The effect of this stimulation on the domestic cat, however, has been largely overlooked. This study thus explored the influence of olfactory...

  14. The influence of visual stimulation on the behaviour of cats housed in a rescue shelter

    | Contributor(s):: Ellis, S. L. H., Wells, D. L.

    This study explored the influence of 5 types of visual stimulation (1 control condition [no visual stimulation] and 4 experimental conditions [blank television screen; and, televised images depicting humans, inanimate movement, animate movement]) on the behaviour of 125 cats housed in a rescue...

  15. The relationship between teat stimulation, oxytocin release and grunting rate in the sow during nursing

    | Contributor(s):: Algers, B., Rojanasthien, S., Uvnas-Moberg, K.

    Before milk let-down, the teats of the sow are stimulated by the piglets for approx. 2 min. Thereafter oxytocin is released, causing a contraction of the alveolar myoepithelium and ejection of the milk. The typical grunting of the sow starts at a low rate, then it suddenly increases and reaches...

  16. Auditory stimulation as enrichment for zoo-housed Asian elephants ( Elephas maximus )

    | Contributor(s):: Wells, D. L., Irwin, R. M.

    This study explored the effect of auditory stimulation on the behaviour and welfare of four zoo-housed, female Asian elephants (Elephas maximus). All animals were exposed, in an ABA design, to two conditions of auditory stimulation: a 'control' (no auditory stimulation), and an 'experimental'...

  17. Fish and welfare: do fish have the capacity for pain perception and suffering?

    | Contributor(s):: Braithwaite, V. A., Huntingford, F. A.

    Humans interact with fish in a number of ways and the question of whether fish have the capacity to perceive pain and to suffer has recently attracted considerable attention in both scientific and public fora. Only very recently have neuroanatomical studies revealed that teleost fish possess...

  18. The influence of auditory stimulation on the behaviour of dogs housed in a rescue shelter

    | Contributor(s):: Wells, D. L., Graham, L., Hepper, P. G.

    This study explored the influence of five types of auditory stimulation (human conversation, classical music, heavy metal music, pop music and a control) on the behaviour of 50 dogs housed in a rescue shelter in the UK [date not given]. The dogs were exposed to each type of auditory stimulation...

  19. Transcranial magnetic stunning of broilers: a preliminary trial to induce unconsciousness

    | Contributor(s):: Lambooij, E., Anil, H., Butler, S. R., Reimert, H., Workel, L., Hindle, V.

    This study was performed to identify whether non-focal transcranial magnetic stimulation (TMS) with an adapted coil for broilers has the potential for use as a non-invasive stunning method for broilers. Application of the TMS probe resulted in dominance of theta and delta waves and appearance of...

  20. Genetics and the development of social behavior in dogs

    | Contributor(s):: Scott, J. P.

    The puppies used in the experiments lived with their litter-mates from birth until 1 yr. of age, first in large nursery rooms and later in spacious outdoor runs. Behavioural tests were given to animals of 5 different breeds: Basenji, Beagle, Cocker Spaniel, Shetland Sheep Dog, and Wire-haired Fox...
