    Contributor(s):: Depenbusch, B. E., Drouillard, J. S., Lee, C. D.

  2. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  3. Effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females

    Contributor(s):: Emous, R. A. van, Kwakkel, R., Krimpen, M. van, Hendriks, W.

    An experiment was conducted to determine the effects of different dietary protein levels during rearing and different dietary energy levels during lay on behaviour and feather cover in broiler breeder females. A 2*3*2 factorial arrangement of treatments was used. A total of 2880 Ross 308...

  4. Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth

    | Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van

    Veal calves in Europe are typically fed large quantities of milk replacer and small amounts of solid feed, a diet known to lead to the development of abnormal oral behaviours in these animals. These abnormal oral behaviours are thought to be an indication of frustration, chronic stress, and...

  5. A note on the cecotrophy behavior in capybara ( Hydrochaeris hydrochaeris )

    | Contributor(s):: Mendes, A., Nogueira, S. S. da C., Lavorenti, A., Nogueira-Filho, S. L. G.

    Six adult capybaras (56 kg) were placed in individual pens and observed for 96 serial hours. During this period a behavioural pattern believed to consist of caecotrophy was observed 243 times. Animals sat on their hind limbs, stretched either limb out, bent over driving their heads in the...

  6. An investigation into the effect of different protein and energy intakes on model tail chewing behaviour of growing pigs

    | Contributor(s):: McIntyre, J., Edwards, S. A.

    Twenty-four crossbred pigs were housed individually and allocated at 62 kg (S.E.M.=0.81) to one of three diets providing differing daily protein and energy intakes: control (C) 1.42 g CP/MJ DE, fed to provide 2.85 maintenance energy; low protein (LP) 0.76 g CP/MJ DE fed to provide the same daily...

  7. Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type

    | Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.

    Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...

  8. Effects of food structure and nutritional quality and animal nutritional state on intake behaviour and food preferences of sheep

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

    There is evidence of the independent effects of plant physical and chemical characteristics on foraging, but little has been done to determine how these traits interact to affect food selection. The effect of the nutritional state of lambs on intake behaviour and preference for feeds with...

  9. Lambs fed protein or energy imbalanced diets forage in locations and on foods that rectify imbalances

    | Contributor(s):: Scott, L. L., Provenza, F. D.

    Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different...

  10. Some aspects of milk that elicit non-nutritive sucking in the calf

    | Contributor(s):: Passille, A. M. de, Rushen, J., Janzen, M.

    Male Holstein dairy calves were allowed to suck a non-nutritive teat after meals of either cow milk or milk replacer, and the amount of non-nutritive sucking that occurred during the 10 min following the meal was observed. There were no differences between milk and commercial milk replacer in the...

  11. Intake and selection for white clover by grazing lambs in response to gastrointestinal parasitism

    | Contributor(s):: Cosgrove, G. P., Niezen, J. H.

    A study was conducted at Palmerston North, New Zealand to determine if lambs grazing at pasture would enhance their nutrient intake in response to parasitism, by selecting more white clover from a mixed grass-clover pasture. The trial used a split-plot design with two grass-clover mixtures as...

  12. Landscape nutritional patterns and cattle distribution in rangeland pastures

    | Contributor(s):: Ganskopp, D. C., Bohnert, D. W.

    On rangelands, uneven or unmanaged livestock distribution can adversely affect plant community composition, riparian function, or displace wildlife. These issues have historic precedents and are still a challenge for those managing rangelands. A thorough understanding of the mechanisms governing...

  13. Relationship between some chemical components of herbage, dietary preference and fresh herbage intake rate by the Japanese serow

    | Contributor(s):: Deguchi, Y., Sato, S., Sugawara, K.

    The serow is a native Japanese mammal and has been designated as a special natural treasure in Japan. However, it has been a pest of crops since the 1970s. Since the serow is an indigenous and protected species, it must be controlled without endangering the animal itself. To do this, it is...

  14. The influence of acidosis and live yeast ( Saccharomyces cerevisiae ) supplementation on time-budget and feeding behaviour of dairy goats receiving two diets of differing concentrate proportion

    | Contributor(s):: Desnoyers, M., Giger-Reverdin, S., Sauvant, D., Bertin, G., Duvaux-Ponter, C.

    Increasing the percentage of concentrate in the diet can influence feeding behaviour of ruminants. It can also lead to subacute rumen acidosis and the addition of yeast to the rumen ecosystem might influence fermentation and subsequently help the ecosystem deal with the consequences of high...

  15. The sexual behaviour of experimentally underfed bulls

    | Contributor(s):: Wierzbowski, S.

    Bulls (18 months old) from each of eight pairs of twins were divided into two groups which were fed a diet containing either 700 g (controls) or 500 g (experimental) crude protein. Sexual behaviour and semen columes were noted every two months until the bulls were five years old. At five years...

  16. Behaviour and percentage eye-white in cows waiting to be fed concentrate - a brief report

    | Contributor(s):: Sandem, A. I., Braastad, B. O., Bakken, M.

    A major task when developing methods of assessing animal welfare is to identify observable external indicators of internal subjective feelings. In this paper, we tested the hypothesis that the percentage of white in the eyes would change as a response to two emotional stimuli; waiting to be fed...

  17. Effects of daily protein intake levels on the oral stereotypic behaviours in energy restricted lambs

    | Contributor(s):: Yurtman, I. Y., Savas, T., Karaagac, F., Coskuntuna, L.

    Effects of daily protein intake levels on oral stereotypic behaviours (OSB) in energy restricted lambs were investigated. 38 male lambs were randomly allotted to 3 treatments. Lambs in the first group (AL) received their ration (12.1 MJ ME/kg DM; 148.6 g CP/kg DM) at ad libitum level, whereas the...

  18. Effects of sward height and concentrate supplementation on the ingestive behaviour of spring-calving dairy cows grazing grass-clover swards

    | Contributor(s):: Rook, A. J., Huckle, C. A., Penning, P. D.

    48 lactating, spring-calving, multiparous, Holstein-Friesian cows, continuously stocked on mixed grass-clover swards, were blocked by calving date, parity and milk yields in week 2 of lactation and randomly allocated to 6 treatments: concentrate supplements 0 and 4 kg/day at sward heights of 40,...

  19. Free-ranging cattle water consumption in southcentral New Mexico

    | Contributor(s):: Rouda, R. R., Anderson, D. M., Wallace, J. D., Murray, L. W.

    Water-drinking behaviour of 67 beef cattle grazing on rangelands (vegetation included Hilaria mutica, Scleropogon brevifolius, Sporobolus airoides, Sporobolus contractus, Sporobolus flexuosus, Prosopis juliflora var. glandulosa, Psorothamnus scoparius and Yucca elata) without or with a protein...

  20. Maintenance and milking behaviours of Murrah buffaloes during two feeding regimes

    | Contributor(s):: Thomas, C. S., Nordstrom, J., Svennersten-Sjaunja, K., Wiktorsson, H.

    Diurnal maintenance behaviour and behaviour during milking in a mechanised system with two feeding regimes were studied in 14 Murrah buffaloes managed in a highly mechanised system. Normal fixed rations of roughage and concentrates and established milking routines (T-I) were compared to a regime...
