  1. Metabolism and cryo-sensitivity of domestic cat (Felis catus) and cheetah (Acinonyx jubatus) spermatozoa

    Contributor(s):: Kimberly Terrell

    Teratospermia (ejaculation of ≥ 60% structurally abnormal spermatozoa) is prevalent among felids facing extinction risk, including the cheetah. This trait also occurs in certain domestic cat populations, providing a valuable research model. Multiple components of sperm function are disrupted in...

  2. Evaluation of cerebral activity in the prefrontal cortex in mood [affective] disorders during animal-assisted therapy (AAT) by near-infrared spectroscopy (NIRS): a pilot study

    Contributor(s):: Aoki, J., Iwahashi, K., Ishigooka, J., Fukamauchi, F., Numajiri, M., Ohtani, N., Ohta, M.

  3. Monitoring stress hormone metabolites as a useful, non-invasive tool for welfare assessment in farm animals

    Contributor(s):: Palme, R.

  4. Stress at slaughter in cattle: role of reactivity profile and environmental factors

    Contributor(s):: Terlouw, E. M. C., Bourguet, C., Deiss, V.

  5. The effects of individual housing on mice and rats: a review

    Contributor(s):: Krohn, T. C., Sorensen, D. B., Ottesen, J. L., Hansen, A. K.

  6. Individual differences in metabolism predict coping styles in fish

    Contributor(s):: Martins, C. I. M., Castanheira, M. F., Engrola, S., Costas, B., Conceicao, L. E. C.

    Studies on metabolism usually rely on measurements of oxygen consumption obtained in respirometry chambers. Despite rigorous standardization there is still considerable inter-individual variation in metabolic rates which is often ignored. Furthermore, housing in respirometry chambers implies...

  7. Oxytocin facilitates behavioural, metabolic and physiological adaptations during lactation. (Special issue: Suckling)

    Contributor(s):: Uvnas-Moberg, K., Johansson, B., Lupoli, B., Svennersten-Sjaunja, K.

    This article aims to propose that oxytocin not only stimulates milk letdown, but also adapts behaviour and physiology to facilitate lactation in mammals, including dairy cattle. Circulating oxytocin as well as neurogenic oxytocin participates in these regulatory processes. In short, oxytocin...

  8. Can emotional reactivity predict stress responses at slaughter in sheep?

    Contributor(s):: Deiss, V., Temple, D., Ligout, S., Racine, C., Bouix, J., Terlouw, C., Boissy, A.

    The slaughter period is very complex and may represent different types of stress for the animal. The way and extent animals react to these stress factors depend on their individual emotional reactivity. The objective of the present study was to determine in sheep relationships between reactivity...

  9. A brief note on the relationship between residual feed intake and aggression behaviour in juveniles of African catfish Clarias gariepinus

    Contributor(s):: Martins, C. I. M., Hillen, B., Schrama, J. W., Verreth, J. A. J.

    Individual differences in maintenance levels have been related with energetically expensive processes such as aggression. This relationship is not fully understood as on one hand individuals with higher maintenance requirements seem to be more aggressive but on the other hand have smaller...

  10. Sequence of food presentation influences intake of foods containing tannins and terpenes

    Contributor(s):: Mote, T. E., Villalba, J. J., Provenza, F. D.

    Interactions among nutrients and secondary compounds in plants can influence the kinds and amounts of different forages herbivores ingest, but little is known about how the sequence of plant ingestion may influence these interactions. The physiological pathways and rates of nutrient and secondary...

  11. Acid-base responses of fat-adapted horses: relevance to hard work in the heat

    Contributor(s):: Kronfeld, D. S., Custalow, S. E., Ferrante, P. L., Taylor, L. E., Wilson, J. A., Tiegs, W.

    Feeding and training may affect acid-base responses to strenuous exercise. Acidosis usually correlates with higher blood lactate concentrations during intense exercise, but alkalosis has been found in horses, and higher lactate responses during sprints have been found in fat adapted horses. A...

  12. Characterising the emotional reactivity of cows to understand and predict their stress reactions to the slaughter procedure

    Contributor(s):: Bourguet, C., Deiss, V., Gobert, M., Durand, D., Boissy, A., Terlouw, E. M. C.

    The present study on 32 Normand cows evaluated whether it is possible to identify, during rearing, individuals likely to be relatively reactive to the slaughter procedure. It evaluated further which factors may contribute to stress during the pre-slaughter period. Behavioural and physiological...

  13. Effects of different degrees of social isolation on the behaviour of weaned piglets kept for experimental purposes

    Contributor(s):: Herskin, M. S., Jensen, K. H.

    The effect of degree of isolation on the behaviour of weaned piglets was investigated using eight replicates of littermates, weaned at 4 weeks and caged for 2 weeks in metabolism chambers under varying degrees of isolation: fully isolated without physical contact with littermates; partly isolated...

  14. Is sodium fluoroacetate (1080) a humane poison? The influence of mode of action, physiological effects, and target specificity

    Contributor(s):: Twigg, L. E., Parker, R. W.

    1080 (sodium fluoroacetate)-baiting programmes are an important and often the only option for reducing the impact of invasive vertebrate pests on biodiversity and agricultural production in Australia and New Zealand. These programmes are generally recognised as being target specific, and...

  15. Raising welfare standards for endurance riding. (UFAW Animal Welfare Series)

    Contributor(s):: Loving, N. S.

    This chapter covers the welfare issues associated with the use of horses in endurance riding. Endurance riding is described as well as the inherent risks of the sport. Regulations and standards that are followed in endurance riding are presented. Measures to avoid metabolic consequences in...
