  1. Feed depredation by European starlings in a Kansas feedlot

    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. 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...

  4. Cow milk and human development and well-being

    | Contributor(s):: Maijala, K.

    This paper reviews the hypotheses of the relationship between milk and human coronary heart disease (CHD). These hypotheses are examined and their original historic deficiencies are discussed. This is followed by the new and emerging scientific evidence to support, question or refute these...

  5. Influence of post-calving regrouping strategy on welfare and performance parameters in dairy heifers

    | Contributor(s):: O'Connell, N. E., Wicks, H. C. F., Carson, A. F., McCoy, M. A.

    Thirty-six Holstein Friesian heifers (dairy herd replacements) were assigned to one of three regrouping treatments during the post-calving period. In Treatment 1, heifers were introduced individually to an established group of cows and heifers within 24 h of calving ('Single - day 1'). In...

  6. 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...

  7. Trainability of eliminative behaviour in dairy heifers using a secondary reinforcer

    | Contributor(s):: Whistance, L. K., Sinclair, L. A., Arney, D. R., Phillips, C. J. C.

    Soiled bedding influences cleanliness and disease levels in dairy cows and there is no evidence of an inherent latrine behaviour in cattle. If cows were trained to use a concrete area of the housing system as a latrine, a cleaner bed could be maintained. Thirteen group-housed, 14-16-month-old...

  8. Effect of different free stall surfaces on behavioural, productive and metabolic parameters in dairy cows

    | Contributor(s):: Calamari, L., Calegari, F., Stefanini, L.

    Two experiments were carried out on 56 lactating dairy cows in an experimental free stall barn comparing four different lying surfaces: straw bedded pack (ST), rubber mat (RM), mattress (MA) and sand (SA). In the first experiment (26 days) cows were allowed to choose between free stalls with each...

  9. Feeding small quantities of grain in the parlour facilitates pre-milking handling of dairy cows: a note

    | Contributor(s):: Ceballos, A., Weary, D. M.

    Food rewards are increasingly recognized as a method of training animals to submit to management procedures that might otherwise require aversive handling. The aim of the current study was to determine if feeding small amounts of concentrate in the parlour could improve entrance behaviour. Cows...

  10. 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...

  11. 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...

  12. Relationships between human-animal interactions and productivity of commercial dairy cows

    | Contributor(s):: Hemsworth, P. H., Coleman, G. J., Barnett, J. L., Borg, S.

    This study examined the relationships between a number of stockperson and cow variables at 66 commercial dairy farms in Victoria, Australia over a 2-year period (1995-1997). Variables such as the attitudes and behaviour of stockpeople toward their cows and the behavioural response to humans and...

  13. 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...

  14. 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...

  15. 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,...

  16. 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...

  17. What components of milk stimulate sucking in calves?

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

    To examine the role of the various components of milk in stimulating non-nutritive sucking, 4-18 week-old male dairy calves (N=10-15 in each experiment) were allowed to suck a dry teat after being given small quantities of milk or reconstituted milk and their sucking behaviour was observed. We...

  18. Effect of breed, season and pasture moisture gradient on foraging behaviour in cattle on semi-natural grasslands

    | Contributor(s):: Hessle, A., Rutter, M., Wallin, K.

    The objectives of this study were to determine the effects of breed, season and pasture moisture gradient on the extent and location of grazing and ruminating behaviour in cattle kept on heterogeneous semi-natural grasslands. Two groups of heifers, 12 of the traditional Swedish breed Vaneko and...

  19. Effect of source and lairage on some behavioural and biochemical measurements of feed restriction and dehydration in cattle at a slaughterhouse

    | Contributor(s):: Jarvis, A. M., Harrington, D. W. J., Cockram, M. S.

    Scan samples of the postural, eating and drinking behaviours of 92 groups of cattle, and focal samples of the eating and drinking behaviour of 378 individuals, were made during the initial 3 h in a commercial slaughterhouse lairage. Cattle which arrived from markets spent more time drinking and...

  20. Effects of protective gates at concentrate feed stations on behaviour and production in dairy cows: a brief note

    | Contributor(s):: Herlin, A. H., Frank, B.

    Concentrate feed stations for dairy cows improve feeding management allowing frequent individual feeding. Concentrates are highly valued by cows and then a cause for competition and aggression. The production and cow welfare may be compromised because of frequent displacements of cows visiting...
