  1. 'Libido' in the larger farm animals: a review

    Contributor(s):: Wodzicka-Tomaszewska, M., Kilgour, R., Ryan, M.

    The term 'libido', first used by Freud to refer to the force by which the sexual instinct is represented in the mind, has become more and more used to refer to some aspects of sexual behaviour in large domestic animals. From being a wide, rather imprecise term, it has come to be defined in a...

  2. 'Upside-down'. The sheep-farmers are facing the presence of the wolves in the French Alps

    Contributor(s):: Fabre, Patrick

  3. A behavioural study of scrapie-affected sheep

    Contributor(s):: Healy, A. M., Hanlon, A. J., Weavers, E., Collins, J. D., Doherty, M. L.

    The behaviour of 12 sheep, suspected of having scrapie, and 12 clinically normal animals from the Irish Republic was observed over a 6-day period [date not given]. Confirmation of the true disease status of the animals was made at postmortem using both histopathological and immunocytochemical...

  4. A breeding goal to improve the welfare of sheep

    Contributor(s):: Scobie, D. R., Bray, A. R., O'Connell, D.

    This paper examines the practical and welfare implications of breeding a polled sheep with a short tail, devoid of wool on the head, legs, belly and breech, which has been proposed as a breeding goal (Scobie et al., Proceedings of the New Zealand Society of Animimal Production 57 (1997) 84-87)....

  5. A close keeper-nonhuman animal distance does not reduce undesirable behavior in contact yard goats and sheep

    Contributor(s):: Anderson, U. S., Maple, T. L., Bloomsmith, M. A.

    This study investigated the relation between zookeeper-nonhuman animal distance and the undesirable behaviour that goats and sheep exhibited toward visitors of Zoo Atlanta's (Georgia, USA) contact yard. It hypothesized that a close distance between keeper and animal would be associated with a...

  6. A colostrum feeder for newborn lambs

    Contributor(s):: Fraser, D., Rushen, J.

    Newborn lambs were studied in 6 experiments to identify simple cues that elicit teat-seeking behaviour, and to incorporate these cues into a device that would guide lambs to find and suck from a colostrum bottle. Lambs were removed from the ewe before sucking and were observed for 10 min in a...

  7. A comparison of commonly used ear tags on the ear damage of sheep

    Contributor(s):: Edwards, D. S., Johnston, A. M., Pfeiffer, D. U.

    The damage caused by ear tags used for sheep identification was investigated in a two-part study. In Part I, ear tags classified as metal loop, golf-tee, single flex or lambtag were inserted into the ears of 62 ewes. The severity of ewe ear lesions was monitored until 20 weeks after ear tag...

  8. A comparison of handling methods relevant to the religious slaughter of sheep

    Contributor(s):: Bates, L. S. W., Ford, E. A., Brown, S. N., Richards, G. J., Hadley, P. J., Wotton, S. B., Knowles, T. G.

    Legislation governing non-stun slaughter of sheep in England requires that they are individually and mechanically restrained for slaughter and not moved for at least 20 s post neck cut, until unconsciousness or insensibility occurs. Complying with the need for individual handling, in what is a...

  9. A comparison of the role of vision and hearing in ewes finding their own lambs

    Contributor(s):: Walser, E. E. S.

  10. A comparison of the role of vision and hearing in lambs finding their own dams

    Contributor(s):: Shillito, E. E.

  11. A comparison of wooden slats and straw bedding on the behaviour of sheep

    Contributor(s):: Gordon, G. D. H., Cockram, M. S.

    The behaviour of 2 groups of sheep was observed when they were placed in a pen on wooden slats and/or straw bedding for 48 h. When sheep were placed in the pen and not given a choice of slats and straw, the proportion of scans spent standing and lying by one group of sheep were not affected by...

  12. A method for assessing the relative sociability of individuals within groups: an example with grazing sheep

    | Contributor(s):: Sibbald, A. M., Elston, D. A., Smith, D. J. F., Erhard, H. W.

    We describe a method for quantifying relative sociability within a group of animals, which is defined as the tendency to be close to others within the group and based on the identification of nearest neighbours. The method is suitable for groups of animals in which all individuals are visible and...

  13. A method for the quantification of butting activity in androgen-treated wethers

    | Contributor(s):: Parrott, R. F.

  14. A new ambulatory data logger for a long-term determination of grazing and rumination behaviour on free-ranging cattle, sheep and goats

    | Contributor(s):: Matsui, K.

    A new ambulatory data logger, which simultaneously records the number of jaw movements and number of pauses between jaw movements longer than 3 s min-1, was developed and tested using cattle, sheep and goats. Since this apparatus was more simple, light-weight and compact than previously developed...

  15. A note on behavioural laterality in neonatal lambs

    | Contributor(s):: Lane, A., Phillips, C.

    In some mammals behavioural laterality is influenced by the perinatal environment, through stress effects on brain lateralisation, and by gender through variation in testosterone secretion. Therefore, a study was conducted on 54 neonatal lambs to determine whether laterality existed at birth and...

  16. A note on behavioural responses of farm animals to ultrasound

    | Contributor(s):: Algers, B.

    Horses, cattle, swine, sheep and poultry all reacted to ultrasound from a device used to clear rats from buildings. Most animals were drawn towards the sound at first and then turned away and kept their ears pointing away from the sound. Poultry showed the least reaction. The device is considered...

  17. A note on changes in ingestive behaviour of sheep following shearing

    | Contributor(s):: Arnold, G. W.

    The grazing behaviour and herbage intake of sheep grazing at 4 stocking rates were recorded before and after shearing in winter. Following shearing, grazing time was reduced but intake of OM/h increased at all stocking rates even though the amount of feed available was very low at the highest...

  18. A note on increased intake in lambs through diversity in food flavor

    | Contributor(s):: Distel, R. A., Rodriguez Iglesias, R. M., Arroquy, J., Merino, J.

    Because preferences for food flavor decline during and after a meal, intake could be increased by offering the same food in different flavors simultaneously. The objective of this study was to determine the effects of offering the same hay with different flavors on forage intake by lambs....

  19. A note on mating preferences in Rasa Aragonesa rams

    | Contributor(s):: Abecia, J. A., Maria, G., Forcada, F.

    Two experiments were conducted to determine whether Rasa Aragonesa rams, a Mediterranean breed, mount ewes randomly or preferentially when presented with a group of 12 oestrous-synchronized ewes during the period of natural seasonal anoestrus. In the first experiment, 12 Rasa Aragonesa ewes were...

  20. A note on ram preference by oestrous ewes: influence of rams' age and sexual performance

    | Contributor(s):: Ramos, M. A., Ungerfeld, R.

    Ewes in oestrus, besides being receptive to rams, develop an active search for them. We performed two experiments to determine if oestrous ewes prefer: (1) high or low sexual-performance rams, and (2) 2-year-old or aged (>8-years-old) rams. In the first experiment, the preference of ewes for rams...
