  1. Exposing violences: using women's human rights theory to reconceptualize food rights

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

    Exposing food violences (hunger, malnutrition, and poisoning from environmental mismanagement) requires policy action that confronts the structured invisibility of these violences. Along with the hidden deprivation of food is the physical and political isolation of critical knowledge on food...

  2. Intake rate during meals and meal duration for sheep in different hunger states, grazing grass or white clover swards

    Contributor(s):: Orr, R. J., Penning, P. D., Rutter, S. M., Champion, R. A., Harvey, A., Rook, A. J.

    Meal patterns and rates of feed intake by grazing herbivores may be markedly different from those found in housed ruminants and monogastrics. Cumulative intakes over the evening meal (satiety curves) were measured using groups of sheep (Ovis aries) grazing monocultures of white clover (Trifolium...

  3. Temporal distribution of sucking behaviour in dairy calves and influence of energy balance

    Contributor(s):: Roth, B. A., Keil, N. M., Gygax, L., Hillmann, E.

    So far, most authors in the literature have suggested that cross-sucking in dairy calves is elicited by milk ingestion, as sucking motivation persists for an additional 12-15 min after milk intake. However, cross-sucking without temporal association to milk ingestion has also been noted in...

  4. The validity of using an approach-avoidance test to measure the strength of aversion to carbon dioxide in rats

    Contributor(s):: Kirkden, R. D., Niel, L., Lee, G., Makowska, I. J., Pfaffinger, M. J., Weary, D. M.

    Approach-avoidance tests are often used to estimate the strength of aversion, by making food rewards available during exposure to a stimulus at a known level of food deprivation. It is reasoned that if subjects are unwilling to tolerate the stimulus even when severely food deprived, their...

  5. Effect of dietary fibre type on physical activity and behaviour in kennelled dogs

    Contributor(s):: Bosch, G., Beerda, B., Hoek, E. van de, Hesta, M., Poel, A. F. B. van der, Janssens, G. P. J., Hendriks, W. H.

    Dog diets may differ in their effectiveness of maintaining satiety after a meal. Consequently, sensations of hunger, feeding motivation, physical activity, and sensitivity to environmental stressors may be increased. Dietary fibre may be effective in prolonging postprandial satiety depending on...

  6. 'Freedom from hunger' and preventing obesity: The animal welfare implications of reducing food quantity or quality

    Contributor(s):: D

  7. Veterinary ethics and production diseases

    Contributor(s):: Rollin, Bernard E.

  8. Equine welfare and ethics

    Contributor(s):: Rollin, B.

  9. Animal welfare: European legislation and future perspectives

    Contributor(s):: Bonafos, L., Simonin, D., Gavinelli, A.

  10. The effect of 2-deoxy-D-glucose on food intake in the pig

    Contributor(s):: Stephens, D. B.

  11. A test of sows' willingness to nurse

    Contributor(s):: Thodberg, K., Jensen, K. H.

    The aim of the study was to validate a test for willingness of sows to nurse to find a test situation in which maximum variation in the nursing motivation of sows was displayed. The factors considered were the interval since last successful nursing, level of hunger of the sow and activity of the...

  12. Behavioural indicators of hunger in dairy calves

    Contributor(s):: Vieira, A. de P., Guesdon, V., Passille, A. M. de, Keyserlingk, M. A. G. von, Weary, D. M.

    Dairy calves are typically fed only about half of their ad libitum milk intake and are highly motivated to drink more milk. The aim of the current study was to describe the behaviours associated with milk hunger in dairy calves, by comparing animals fed restricted quantities of milk (two milk...

  13. Behavioural responses by dairy cows provided two hays of contrasting quality at dry-off

    | Contributor(s):: Valizaheh, R., Veira, D. M., Keyserlingk, M. A. G. von

    A typical dairy cow lactation cycle consists of 305 days of lactation followed by a 40-60 day period where she is not lactating (dry period). There is considerable variation in the procedures used to bring the lactation to an end (dry-off); however, commonly a combination of reduced milking...

  14. How hungry are broiler breeders subjected to commercial food restriction during rearing?

    | Contributor(s):: Savory, C. J., Maros, K., Rutter, S. M.

  15. Why do pigs root and in what will they root? A review on the exploratory behaviour of pigs in relation to environmental enrichment

    | Contributor(s):: Studnitz, M., Jensen, M. B., Pedersen, L. J.

    The intention of the new European legislation on rooting materials for pigs is to improve the welfare of pigs. The question is: which materials are suitable rooting materials for pigs? To answer this question the motivation for exploration in pigs is elucidated and the needs of the pigs in this...

  16. Milking frequency and nutritional level affect grazing behaviour of dairy cows: a case study

    | Contributor(s):: O'Driscoll, K., O'Brien, B., Gleeson, D., Boyle, L.

    The aim of this study was to evaluate the effect of milking frequency (MF) at two nutritional levels (NL) on grazing behaviour of dairy cows. Animals (n=48) were randomly assigned to one of four treatments from calving in a 2x2 factorial design for an entire lactation: once (OAD) or twice (TAD) a...

  17. Effect of scattered feeding and feeding twice a day during rearing on indicators of hunger and frustration in broiler breeders

    | Contributor(s):: Jong, I. C. de, Fillerup, M., Blokhuis, H. J.

    Broiler breeders are routinely fed restricted during rearing which has a major negative effect on their welfare. They suffer from hunger and frustration from thwarting of feeding. The aim of this experiment was therefore to study if broiler breeder welfare can be improved by changes in the...

  18. Feeding pigs: divergence of behavioural and physiological requirements

    | Contributor(s):: Lawrence, A. B., Appleby, M. C., Macleod, H. A.

    In experiments in which hunger in Large WhitexLandrace boars was measured by conditioning them to press a panel to receive 7-g rewards of food, it was concluded that restricting pigs to low food allowances results in a high level of hunger throughout the day. It is suggested that commercial food...

  19. Methodology for measuring hunger and food needs using operant conditioning in the pig

    | Contributor(s):: Lawrence, A. B., Illius, A. W.

    Two reward schedules were compared for their sensitivity in measuring motivational changes due to feed restriction in Large White X Landrace pigs. Six boars were each restricted (proportionally) to 0.8, 0.6 and 0.4 of their predicted ad libitum feed intake (PFI) in a Latin square design....

  20. The influence of hunger on object play by adult domestic cats

    | Contributor(s):: Hall, S. L., Bradshaw, J. W. S.

    The hypothesis that object play by adult domestic cats may be indistinguishable from predatory behaviour at the motivational level was investigated by examining the effect of hunger on play. Cats were presented with either a large toy or a small toy, either 0 h and 16 h after their last meal. The...
