  1. Bioacoustic tools for enhancing animal management and productivity: effects of recorded calf vocalizations on milk production in dairy cows

    Contributor(s):: McCowan, B., DiLorenzo, A. M., Abichandani, S., Borelli, C., Cullor, J. S.

    Vocal communication mediates social relationships in many mammalian species and can be particularly important in mother-infant interactions. Mammalian species in general and cows in particular exhibit a strong mother-infant bond that is frequently expressed through vocal exchanges among mothers...

  2. Choice of scan-sampling intervals - an example with quantifying neighbours in dairy cows

    Contributor(s):: Neisen, G., Wechsler, B., Gygax, L.

    To date, only a few studies using scan-sampling intervals to record neighbours in groups of animals explain how the interval length was chosen. In this study, we investigated the effects of different scan-sampling intervals, behavioural context, and the definition of neighbours on the accuracy of...

  3. Consistency of individual behavioural characteristics of dairy cows in their home pen

    Contributor(s):: Schrader, L.

    The aim of this study was to identify reliable individual behavioural characteristics of dairy cows based on aspects of their spontaneous behaviour and their reactions towards behavioural tests performed in their home pen. The parameters measured were supposed to reflect how easily the behaviour...

  4. Consistency of side choice in the milking parlour by Holstein-Friesian cows and its relationship with their reactivity and milk yield

    Contributor(s):: Paranhos da Costa, M. J. R., Broom, D. M.

    Dairy cows often have to choose which of two sides to enter in the milking parlour. Some cows are very consistent in this choice, and it is common to assume that when these cows are more disturbed are being milked in their non-preferred side. Such disturbance might involve significantly poor...

  5. Cow behaviour on a new grooved floor in comparison with a slatted floor, taking claw health and floor properties into account

    Contributor(s):: Stefanowska, J., Swierstra, D., Braam, C. R., Hendriks, M. M. W. B.

    The objective of this study was to compare the behaviour of cows on a grooved floor with that of cows kept on a slatted floor. The trial was carried out with 2 groups of 12 Holstein-Friesian cows kept in a cowshed with 2 symmetrical halves, identical except for the floor. One floor was grooved...

  6. Cow behaviour pattern recognition using a three-dimensional accelerometer and support vector machines

    Contributor(s):: Martiskainen, P., Jarvinen, M., Skon, J. P., Tiirikainen, J., Kolehmainen, M., Mononen, J.

    Automated animal behaviour monitoring systems have become increasingly appealing for research and animal production management purposes. However, many existing systems are suited to measure only one or two behaviour patterns or activity states at a time. We aimed to develop and pilot a method for...

  7. Cross-sucking and gradual weaning of dairy calves

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

    To examine the effect of gradually weaning calves off milk on cross-sucking, and the relationship between cross-sucking and energy intake, 32 Holstein calves were housed in groups of four and allowed 12 L/d of milk until the process of weaning began. The process of weaning was either abrupt at 41...

  8. Dairy cow interactions with an automatic milking system starting with 'walk-through' selection

    Contributor(s):: Stefanowska, J., Tiliopoulos, N. S., Ipema, A. H., Hendriks, M. M. W. B.

    The behaviour of 24 lactating cows was studied in a loose-housed system with access to an automatic milking system (AMS). Access to the AMS was via a passage between the lying and the feeding areas ('walk-through' area) in which the cow was scanned while moving and either allowed into the AMS, if...

  9. Dairy cows prefer shade that offers greater protection against solar radiation in summer: shade use, behaviour, and body temperature

    Contributor(s):: Schutz, K. E., Rogers, A. R., Cox, N. R., Tucker, C. B.

    There is considerable evidence that shade is a valuable resource for cattle in summer, but less is known about the important design features of effective shade. The aim of this experiment was to investigate if lactating dairy cows have a preference for shade that offers greater protection against...

  10. 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...

  11. Dairy cows' fear of people: social learning, milk yield and behaviour at milking

    Contributor(s):: Munksgaard, L., Passille, A. M. de, Rushen, J., Herskin, M. S., Kristensen, A. M.

    We examined the effects of the presence of an unfamiliar, a gentle or an aversive handler during milking on behaviour and milk yield, and whether cows can learn to approach or avoid a handler by observing the neighbouring cow's responses. In Experiment 1, Danish Friesian cows (n=16) were treated...

  12. Demonstration and verification of a milking order in dairy sheep and its extent and consistency

    Contributor(s):: Wasilewski, A.

    The objective of this study was to investigate whether dairy sheep, like cows, organize themselves into a well-defined sequence at entry into the milking parlour and to quantify the extent (i.e., proportion of flock members with a favourite position in the sequence) and consistency of the order...

  13. 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...

  14. 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...

  15. Effect of gradual transition from maternal to reconstituted milk on behavioural, endocrine and immune responses of lambs

    Contributor(s):: Sevi, A., Napolitano, F., Casamassima, D., Annicchiarico, G., Quarantelli, T., Paola, R. de

    18-24 h after parturition, 20 Comisana lambs were separated from their dams and were subsequently offered a commercial milk substitute (Sub) or were subjected to a gradual transition from maternal to reconstituted milk over 10 days (Mix). Lambs had free access to milk for 3 h a day. A further 10...

  16. 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...

  17. Effect of music on voluntary approach of dairy cows to an automatic milking system

    Contributor(s):: Uetake, K., Hurnik, J. F., Johnson, L.

    A group of 19 mid- and late-lactating Holstein cows with 2 months prior experience of twice daily milking in the AMS was used in this study. The cows were housed in a free-stall barn with slatted floors and fed a complete mixed ration using an indoor feeding trough. They were also offered 1.5...

  18. Effect of stage of lactation and breed on dairy cows' acceptance of foster calves

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

    We examined the time after separation from their own calf, dairy cows best accept foster calves, and if there are differences between two breeds in their willingness to accept foster calves. Forty-eight cows, 24 Swedish Red and White (SRW) and 24 Swedish Holstein-Friesian (SHF) were used. They...

  19. 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...

  20. Effects of different suckling systems on milk production, udder health, reproduction, calf growth and some behavioural aspects in high producing dairy cows - a review. (Special issue: Suckling)

    Contributor(s):: Krohn, C. C.

    This article discusses the consequences of different suckling systems in industrial countries on milk production, udder health, reproduction and behaviour of high-producing dairy cows, and the effects on the gain, health and behaviour of the calves. The suckling systems are divided into three...
