  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. A concept of welfare based on reward evaluating mechanisms in the brain: anticipatory behaviour as an indicator for the state of reward systems

    Contributor(s):: Spruijt, B. M., Bos, R. van den, Pijlman, F. T. A.

    In this review we attempt to link the efficiency by which animals behave (economy of animal behaviour) to a neuronal substrate and subjective states to arrive at a definition of animal welfare which broadens the scope of its study. Welfare is defined as the balance between positive (reward,...

  3. A general review and survey of maternal behaviour in the rabbit

    Contributor(s):: Verga, M., Dell'Orto, V., Carenzi, C.

    The literature on maternal behaviour of rabbits is reviewed with special emphasis on socialization, mating, nest building and parturition. Results of a survey of mating and maternal behaviour in rabbits are reported.

  4. A new questionnaire examining general attitudes toward animals in Cyprus and the United Kingdom

    Contributor(s):: Zalaf, A., Egan, V.

    A review of the animal welfare literature indicates that all the current measures used to evaluate it have limitations in how they assess attitudes toward animals and their care. Few studies have examined animal welfare outside non-Western nations, although attitudes toward animals and their...

  5. A philosophical consideration of awareness

    Contributor(s):: Jennings, R. C.

  6. A Pickup Load of Pigs: The Feral Swine Pandemic

    Contributor(s):: Jackson, P.

  7. A review of behavioural and physiological responses of sheep to stressors to identify potential behavioural signs of distress

    Contributor(s):: Cockram, M. S.

    This paper discusses the potential for using observations of behaviour to recognise distress in sheep. The term distress is used to describe situations in which an animal is likely to be suffering, and is indicating this by overt behavioural signs. Literature on the behavioural responses of sheep...

  8. A review of cat behavior in relation to disease risk and management options

    Contributor(s):: Lepczyk, C. A., Lohr, C. A., Duffy, D. C.

    Domestic cats ( Felis catus) are a common household pet and also a notorious invasive species around the world. Because cat numbers have been increasing in many locations it is critical to work on management solutions that help to reduce threats posed by cats. With regard to cat behavior, one of...

  9. A review of environmental enrichment for pigs housed in intensive housing systems

    Contributor(s):: de Weerd, H. A. van, Day, J. E. L.

    This paper critically reviews the literature concerning environmental enrichment for weaner, grower and finisher pigs housed in intensive (indoor) production systems. The thesis of our review is that successful enrichment should meet four criteria of success: (1) it should increase...

  10. A review of historically significant publications from German speaking countries concerning the behaviour of domestic farm animals

    Contributor(s):: Sambraus, H. H.

    German language publications up to and including 1958 which concerned the behaviour of domestic farm animals are reviewed. The subjects covered include behaviour of cows on different grazing systems, and eating habits in cattle.

  11. A review of nutritional and motivational factors contributing to the performance of regurgitation and reingestion in captive lowland gorillas ( Gorilla gorilla gorilla )

    Contributor(s):: Lukas, K. E.

    A review. Regurgitation and reingestion is a common phenomenon in captive lowland gorillas, but it has never been reported in wild populations. Although changes in diet have been shown to reduce the behavior, little is known about the underlying mechanisms that lead to its development and...

  12. A review of some factors affecting the expression of libido in beef cattle, and individual bull and herd fertility

    Contributor(s):: Petherick, J. C.

    This paper examines some of the factors that affect the expression of libido in beef cattle, focusing on the male and the free-ranging situation. The ways in which bull libido is assessed and the relationship between libido test results and fertility are discussed. Genetics play a role in...

  13. A review of the behavioral and neurochemical consequences of early weaning in rodents. (Special Issue: Early Weaning.)

    Contributor(s):: Kikusui, T., Nakamura, K., Mori, Y.

    In mammals, mother-infant bonding is based on the dependence of the infant on the mother for sustenance, i.e., the infant suckles milk, but also involving a need for physical contact. Weaning is one of the most important events that occur in developing animals and the timing of natural weaning is...

  14. A review of the behavioural and physiological adaptations of hill and lowland breeds of sheep that favour lamb survival

    Contributor(s):: Dwyer, C. M., Lawrence, A. B.

    Extensively managed animals, often living in harsh and unfavourable environments, need specific adaptations that promote survivability. This is particularly important at parturition and during the neonatal period, when ewe and lamb mortality is highest. To understand the survival adaptations of...

  15. A review of the behavioural mechanism of milk ejection of the domestic pig

    Contributor(s):: Fraser, D.

    The sow has complex nursing and suckling behaviour, consisting of several distinct phases of sucking by the piglets and a characteristic pattern of grunting by the sow. A review of observations and experimental findings suggests cause-and-effect relationships between the different elements of sow...

  16. A review of the housing requirements of domestic cats ( Felis silvestris catus ) kept in the home

    Contributor(s):: Rochlitz, I.

    Cats are a popular companion animal in the United States, the United Kingdom and most of western Europe. While a few studies on cat behaviour and interactions between cats and humans have been conducted in the home setting, most refer to cats housed in laboratories, catteries and shelters....

  17. A review of the human-horse relationship

    Contributor(s):: Hausberger, M., Roche, H., Henry, S., Visser, E. K.

    Despite a long history of human-horse relationship, horse-related incidents and accidents do occur amongst professional and non professional horse handlers. Recent studies show that their occurrence depend more on the frequency and amount of interactions with horses than on the level of...

  18. A review of welfare in cattle, sheep and pig lairages, with emphasis on stocking rates, ventilation and noise

    Contributor(s):: Weeks, C. A.

    Appropriate space allowances for animals are yet to be specifically determined for lairage. Space allowances that may be suitable for animals in lairage are suggested, based on reviewed studies of animals in transport, lairage and on farm. The longer animals are in lairage the more space they...

  19. A view from the bridge: subjectivity, embodiment and animal minds

    Contributor(s):: Dutton, D., Williams, C.

    In contemporary discussions of animal mind the difficulty of studying the nature of private, subjective awareness in animals is often seen as a barrier to a fuller understanding of animal experience. Relatively little work has focused on more recent psychological accounts of mind that emphasize...

  20. An ethological approach to determining housing requirements of gamebirds in raised laying units

    Contributor(s):: Matheson, S. M., Donbavand, J., Sandilands, V., Pennycott, T., Turner, S. P.

    Each year, the UK rears around 20-30 million pheasants and 3-6 million red-legged partridges for shooting purposes. However, welfare organisations and some members of the gamebird industry itself have raised concerns about the use of raised laying units for breeding gamebirds. Although the...
