    2nd Annual Dairy Cattle Welfare Symposium: Milwaukee, Wisconsin

    The Dairy Cattle Welfare Symposium will bring together industry leaders to discuss best recommended practices of dairy cattle welfare and their implementation with focus on public relations,...

  2. A brief report on the relationship between level of milk production and estrous behavior of lactating dairy cows

    Contributor(s):: Lopez, H., Satter, L. D., Wiltbank, M. C.

    The objective of this study was to evaluate if there was an association between milk production and duration of estrus in lactating cows as determined by standing activity recorded by a radiotelemetry system. Holstein cows (n=42) were fitted with a radiotelemetric transmitter that allowed...

  3. A note: the effects of human handling on heart girth, behaviour and milk quality in dairy goats

    Contributor(s):: Jackson, K. M. A., Hackett, D.

    Research on cattle, lambs and pigs suggests that when animals do not receive positive physical attention ("gentling") from their stockpersons, they become fearful, stressed, less productive, and less healthy overall. The purpose of this experiment was to examine the effects that positive human...

  4. A novel environment inhibits milk ejection in the pig but not through HPA activity

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

    Six sows (3-14 days postpartum) were placed with their piglets in a different farrowing pen (novel environment) for 2 h or were driven into the new pen then immediately returned to their own pen (control). All sows were subject to both treatments over 2 consecutive days. Nursings were recorded as...

  5. A possible relationship between the flinch, step and kick response and milk yield in lactating cows

    Contributor(s):: Willis, G. L.

    The av. milk yield and incidence of flinching, kicking and stepping during teatcup placement and removal (FSK response) were both higher among 10 randomly selected Friesian X Jersey cows in periods of 5 and 4 days when they were milked by one herdsman than in 5 days when they were milked by...

  6. A prospective exploration of farm, farmer, and animal characteristics in human-animal relationships: an epidemiological survey

    Contributor(s):: Roches, A. de B. des, Veissier, I., Boivin, X., Gilot-Fromont, E., Mounier, L.

    Human-animal relationships are essential for dairy farming. They affect work comfort and efficiency, as well as milk production. A poor human-animal relationship can result in stress and accidents to both animals and caretakers and needs to be improved. However, many studies have demonstrated the...

  7. A quantitative analysis of social behaviour of different crossbreds of dairy cattle kept in loose housing and its relationship to productivity

    Contributor(s):: Jezierski, T. A., Podluzny, M.

    The social behaviour of Polish Black-and-White dairy cattle (BW) was compared with that of the F1-crossbreds of BW with Jersey (BW x J), Ayrshire (BW x Ay), Holstein-Friesian (BW x HF) and Swedish Black-and-White (BW x SLB). The crossbreds BW x J proved to be most aggressive, excitable and...

  8. A review of the behavioural mechanism of milk ejection of the domestic pig

    Contributor(s):: Fraser, D.

    The sow has complex nursing and suckling behaviour, consisting of several distinct phases of sucking by the piglets and a characteristic pattern of grunting by the sow. A review of observations and experimental findings suggests cause-and-effect relationships between the different elements of sow...

  9. Age at introduction to the group affects dairy calves' use of a computer-controlled milk feeder

    Contributor(s):: Jensen, M. B.

    Use of computer-controlled milk feeders in dairy calves often involves large group sizes and continuous introduction of new calves, which may cause problems due to competition especially for young calves. Ninety-eight dairy calves were paired (one 6-day-old and one 14-day-old) and introduced into...

  10. Allosuckling in cattle: gain or compensation?

    Contributor(s):: Vichova, J., Bartos, L.

    The objective of this study was to assess the impact of allosuckling on the growth of calves in a herd of domestic cattle. We determined (i) if allosucking calves achieved a better weight gain than non-allosucking calves ingesting milk surplus to maternal milk supply or if they were compensating...

  11. An aversive milker causes fear, but does not influence milk yield of Holstein cows

    Contributor(s):: Hotzel, M. J., Machado Filho, L. C. P., Yunes, M. C., Silveira, M. C. A. C. da

    In the present study, the hypothesis that fear of humans is long-lasting and may influence milk production in Holstein-Friesian cows was tested. One person (the aversive handler) carried out two daily sessions of an aversive treatment during 21 days, where each cow received two slaps on the rump...

  12. An ethicist's commentary on the case of a client ignoring organic standards

    Contributor(s):: Rollin, B. E.

  13. An ethicist's commentary on the case of determining withdrawal time for off-label drug usage in sheep

    Contributor(s):: Rollin, B. E.

  14. An ethicist's commentary on the case of the farmer advised by "experts"

    Contributor(s):: Rollin, B. E.

  15. An ethicist's commentary on the raw milk case

    Contributor(s):: Rollin, B. E.

  16. An evaluation of mattresses and mats in two dairy units

    Contributor(s):: Chaplin, S. J., Tierney, G., Stockwell, C., Logue, D. N., Kelly, M.

    In order to investigate the relative merits of mats and mattresses in terms of cow comfort, production and performance, 29 cows were housed on ethylethene vinyl acetate mats and 29 on mattresses of loose rubber crumb with a polypropylene cover, at each of 2 similar dairy units of the Scottish...

  17. An exploratory study on the effects of a straw dispenser in farrowing crates

    Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.

    The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...

  18. An investigation of factors related to the dominance order of a herd of dairy cows of similar age and breed

    Contributor(s):: Collis, K. A.

    Dominance value was found to be negatively correlated with height at withers (P

  19. An observational study of the effects of therapeutic hoof blocks on the locomotion, behavior, and production of healthy dairy cattle

    Contributor(s):: Cutler, J. H., Shearer, J. K., Kelton, D. F., Cramer, G., Gorden, P. J., Millman, S. T.

    Therapeutic hoof blocks have been recommended for treatment of sole ulcers in dairy cattle; however, they are underutilized in the industry. Twenty Holstein cows were randomly assigned to receive a wooden hoof block applied to the left hind leg ( n=5), to the right hind leg ( n=5), or no hoof...

  20. Analysis of factors influencing animal welfare, animal health & performance of dairy cows in loose housing with cubicles

    Contributor(s):: Mulleder, C., Waiblinger, S., Troxler, J.

    A study investigated a random sample of 80 dairy herds of 21-80 Simmental cows during the winter months of 2002 and 2003 in Lower and Upper Austria. An assessment was made of buildings and fittings, feeding, behaviour and interaction of cows and personnel, and welfare in terms of lameness and...
