  1. Both energy content and bulk of food affect stereotypic behaviour, heart rate and feeding motivation of female pigs

    Contributor(s):: Robert, S., Rushen, J., Farmer, C.

    The effect of high-fibre diets on feeding motivation and feeding-related stereotypic behaviour was examined in gilts. Forty gilts were fed on a concentrate diet (CONC) or high-fibre diets balanced for energy (WHEAT, wheat bran and maize cobs or OAT, oat hulls and oat) or with a lower energy...

  2. Cockatiels ( Nymphicus hollandicus ) reject very low levels of plant secondary compounds

    Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.

    The rejection thresholds of caged cockatiels (Nymphicus hollandicus) were tested to determine their sensitivity to plant secondary compounds. Both alkaloids and tannins were tested using a two-bottle method in which purified water was always available in one bottle and an aqueous test solution...

  3. Colour preferences of domestic chicks in relation to food and water presentation

    Contributor(s):: Roper, T. J., Marples, N. M.

    The colour preferences of chicks presented with artificially coloured food (chick starter crumbs) and water were investigated. In experiment 1, 96 pairs of chicks received red, green or black food in the form of a small pile of crumbs placed on the floor of the test cage, or red, green or black...

  4. Comparative behaviour of free-ranging blackbirds ( Turdus merula ) and silvereyes ( Zosterops lateralis ) with hexose sugars in artificial grapes

    Contributor(s):: Saxton, V. P., Hickling, G. J., Trought, M. C. T., Creasy, G. L.

    In order to detect bird responses to sugar parameters of ripening grapes, artificial grapes containing controlled concentrations of hexose sugars were offered to free-range blackbirds (Turdus merula) and silvereyes (Zosterops lateralis). Time-lapse video was used to observe the two species of...

  5. Comparison of the behaviour of Awassi lambs in cafeteria feeding system with single diet feeding system

    Contributor(s):: Keskin, M., Sahin, A., Bicer, O., Gul, S.

    This study was carried out to compare behavioural activities of Awassi lambs in cafeteria feeding system with conventional feeding (control) that animals fed concentrate. Sixteen, 3-month-old male lambs were housed individually for 42 days. The main effect was on the feeding systems, cafeteria...

  6. Cross-sucking and other oral behaviours in calves, and their relation to cow suckling and food provision

    Contributor(s):: Margerison, J. K., Preston, T. R., Berry, N., Phillips, C. J. C.

    Abnormal oral behaviour in calves is believed to develop when there is a lack of opportunity to suckle, but it is unclear whether they need access to their mother or whether a multiple suckling system will suffice to prevent this behaviour from developing. Therefore, in an initial experiment, the...

  7. Cross-suckling and nursing synchronisation in group housed lactating sows

    Contributor(s):: Maletinska, J., Spinka, M.

    Group housing systems for lactating sows with piglets enable the animals to behave more naturally than traditional restrictive systems. However, piglets may occasionally suckle from other sows than their mother. The influence of litter size, age of the litter, mother parity, piglet gender and, in...

  8. Dairy cows trade-off feed quality with proximity to a dominant individual in Y-maze choice tests

    Contributor(s):: Rioja-Lang, F. C., Roberts, D. J., Healy, S. D., Lawrence, A. B., Haskell, M. J.

    In this experiment choice tests were used as a tool to determine how dairy cows perceive their feeding environment with specific emphasis on understanding the challenges that low ranking animals face when forced to feed in the presence of socially dominant cows. It was hypothesised that cows...

  9. Development of stereotypic behaviour in sows fed a starch diet or a non-starch polysaccharide diet during gestation and lactation over two parities

    Contributor(s):: Peet-Schwering, C. M. C. van der, Spoolder, H. A. M., Kemp, B., Binnendijk, G. P., Hartog, L. A. den, Verstegen, M. W. A.

    The effect of feeding sows a starch diet or a diet with a high level of fermentable non-starch polysaccharides (NSP) during gestation, lactation or both gestation and lactation over the first two parities on the development of stereotypic behaviour was studied in sows housed in groups during...

  10. Diet preference for grass and legumes in free-ranging domestic sheep and cattle: current theory and future application

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

    This paper reviews the current theory and potential practical applications of research on the diet preference for grass and legumes in grazing domestic sheep and cattle. Although much of this work has focussed on grass and clover as a model system, it has wider theoretical implications and...

  11. Dietary preference of dairy heifers grazing ryegrass and white clover, with and without an anti-bloat treatment

    Contributor(s):: Rutter, S. M., Orr, R. J., Yarrow, N. H., Champion, R. A.

    The effect of an antibloat treatment on the dietary preference of nonpregnant Holstein x Friesian heifers for ryegrass and white clover was studied. Eight groups of two heifers grazed 0.51 ha plots containing adjacent monocultures of grass alongside clover with either 25 or 75% clover (by ground...

  12. Discriminating among novel foods: effects of energy provision on preferences of lambs for poor-quality foods

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

    A study was conducted to better understand how lambs discriminate among novel foods based on flavour and post-ingestive effects. The manner in which temporal sequence of food ingestion and post-ingestive feedback affected preference when lambs were fed flavoured wheat straw (a poorly nutritious...

  13. Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?

    Contributor(s):: Mason, G., Mendl, M.

    Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.

  14. Does the number of daily meals affect feeding motivation and behaviour of gilts fed high-fibre diets?

    Contributor(s):: Robert, S., Bergeron, R., Farmer, C., Meunier-Salaun, M. C.

    The feeding motivation and feeding-related stereotypies of pregnant gilts fed high-fibre (HF) or concentrate (C) diets in one or two daily meals were compared. 24 gilts were fed either a concentrate or high-fibre diet with the same daily intake of energy and major nutrients. The effect of the...

  15. Effect of acute histamine and pentagastrin on voluntary food intake in growing chickens

    Contributor(s):: Saadoun, A., Alvarez, A. F., Cabrera-Saadoun, M. C.

    Seven male chickens, 5 weeks old, were injected intraperitoneally with histamine 0, 500 or 1000 micro g/kg body weight. Feed intake was measured at 6, 15, 30, 45, 60, 90 and 120 min and water intake at 15, 30, 45, 60, 90 and 120 min after injection of histamine. A second experiment was carried...

    Contributor(s):: Mattiello, S., Redaelli, W., Carenzi, C., Crimella, C.

    The present study aimed to investigate in the field the effect of the presence of cattle on red deer behavioural patterns, in order to provide information that could be used to improve land management strategies. The research was carried out in a summer range at 1500 m a.s.l. in the Italian...

  17. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal ("low")) and two...

  18. Effect of feeding duration and rumen fill on behaviour in dairy cows

    Contributor(s):: Lindstrom, T., Redbo, I.

    The aim of the present experiment was to test the hypothesis that oral manipulation of feed is a behavioural need in cattle, irrespective of actual rumen load. Twelve rumen fistulated cows were used and subjected to four different treatments: low rumen content+long duration of eating (A), high...

  19. Effect of milkflow rate and presence of a floating nipple on abnormal sucking between dairy calves. (Special issue: Suckling)

    Contributor(s):: Loberg, J., Lidfors, L.

    The aim of this study was to investigate if access to an artificial teat, compared with an open bucket, would decrease abnormal sucking in calves held in pairs, and if the calves would perform less abnormal sucking if they spent more time drinking or sucking milk. Sixteen calves of Swedish Red...

  20. Effects of amount of milk, milk flow and access to a rubber teat on cross-sucking and non-nutritive sucking in dairy calves. (Special issue: Suckling)

    Contributor(s):: Jung, J., Lidfors, L.

    The aim of this study was to test the effects of different amounts of milk, rate of milk flow, and access to a teat after milk intake on non-nutritive sucking on an empty teat and on cross-sucking on other calves in Bos taurus dairy calves. An additional aim was to test if calves prefer to...
