  2. A conceptual model of the human-animal relationships dynamics during newborn handling on cow-calf operation farms

    Contributor(s):: Costa, F. de O., Valente, T. S., Toledo, L. M. de, Ambrosio, L. A., Campo, M. del, Costa, M. J. R. P. da

  3. On-farm testing of dairy calves' avoidance response to human approach effects of sex, age and test order

    Contributor(s):: Ellingsen-Dalsjau, K., Dean, K. R., Rousing, T.

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

    Full-text: Available

    | 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...

  5. Social networks and welfare in future animal management

    | Contributor(s):: Koene, P., Ipema, B.

    It may become advantageous to keep human-managed animals in the social network groups to which they have adapted. Data concerning the social networks of farm animal species and their ancestors are scarce but essential to establishing the importance of a natural social network for farmed animal...

  6. Availability and use of designated hospital pens in Danish dairy herds

    | Contributor(s):: Houe, H., Thomsen, P. T., Amdi, C., Herskin, M. S., Forkman, B., Jensen, M. B.

    The objective of this study was to describe the availability and use of designated hospital pens in Danish dairy herds and to analyse the association between availability and use of hospital pens and the herd-level incidence of reported disease treatments. Hospital pens were divided into either...

  7. Welfare outcomes for 3- and 6-month-old beef calves in a tropical environment castrated surgically or by applying rubber rings

    | Contributor(s):: Petherick, J. C., Small, A. H., Reid, D. J., Colditz, I. G., Ferguson, D. M.

    Castration of cattle using rubber rings is becoming increasingly popular due to the perceived ease of the procedure and greater operator safety when compared with surgical castration. Few comparative studies have investigated the effects of different castration methods and calf age on welfare...

  8. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    | Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  9. Stakeholder views on treating pain due to dehorning dairy calves

    | Contributor(s):: Robbins, J. A., Weary, D. M., Schuppli, C. A., Keyserlingk, M. A. G. von

    A common and painful management practice undertaken on most dairy farms is dehorning young calves (also called 'disbudding' when done on calves less than about two months of age). Despite much evidence the practice is painful, and effective means available to mitigate this pain, it is frequently...

  10. Effects of gentle interactions on the relationship with humans and on stress-related parameters in group-housed calves

    | Contributor(s):: Lurzel, S., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    Although the relationship between farm animals and humans has strong implications for animal welfare and productivity, there have been few experimental studies on the influence of gentle interactions in group-housed calves. In the present study, Austrian Simmental calves were housed in groups of...

  11. Calf mortality in semi-domestic reindeer ( Rangifer tarandus) in a Scottish herd: the impact of maternal age and individual differences between cow

    | Contributor(s):: Jorgensen, M. W., Jarvis, S., Brewer, M. J., Goddard, P. J.

    High calf mortality rate is a significant problem facing semi-domestic reindeer ( Rangifer tarandus) production around the world. Mortality rates, commonly due to predation, can range from 5 to 70%, which constitutes a great welfare concern. This study examined the influence of quantifiable...

  12. Does temperament affect learning in calves?

    | Contributor(s):: Webb, L. E., Reenen, C. G. van, Jensen, M. B., Schmitt, O., Bokkers, E. A. M.

    The aim of the study was to investigate how temperament affects learning ability in calves. Nine two-month-old Holstein-Friesian bull calves were subjected to four challenge tests: novel object (NOT), novel environment (NET), social isolation (SIT), and social isolation with a novel environmental...

  13. The effect of physical contact between dairy cows and calves during separation on their post-separation behavioural response

    | Contributor(s):: Johnsen, J. F., Ellingsen, K., Grondahl, A. M., Boe, K. E., Lidfors, L., Mejdell, C. M.

    Premature breaking of the maternal bond between a cow and her calf triggers a strong behavioural response which renders separation and weaning major welfare challenges in suckling systems. Fence-line separation and weaning allowing physical contact has been evaluated for beef cattle and is...

  14. Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective

    | Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.

    Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...

  15. Animal welfare concerns and values of stakeholders within the dairy industry

    | Contributor(s):: Ventura, B. A., Keyserlingk, M. A. G. von, Weary, D. M.

    This paper describes the perspectives of stakeholders within the North American dairy industry on key issues affecting the welfare of dairy cattle. Five heterogeneous focus groups were held during a dairy cattle welfare meeting in Guelph, Canada in October 2012. Each group contained between 7 and...

  16. Effects of mother versus artificial rearing during the first 12 weeks of life on challenge responses of dairy cows

    | Contributor(s):: Wagner, K., Seitner, D., Barth, K., Palme, R., Futschik, A., Waiblinger, S.

    We investigated the effects of mother versus artificial rearing on the responses to a social and a non-social challenge in adulthood. Rearing of treatment groups only differed during the first 12 weeks of life. Artificially reared animals were separated from their mothers within 24 h after birth...

  17. The effect of nursing on the cow-calf bond

    | Contributor(s):: Johnsen, J. F., Passille, A. M. de, Mejdell, C. M., Boe, K. E., Grondahl, A. M., Beaver, A., Rushen, J., Weary, D. M.

    Dairy calves are often separated from the cow soon after birth and prevented from nursing, but little is known about the effects of nursing on the development of the cow-calf bond. This study evaluated the effect of nursing on affiliative behaviours between the dam and her calf including...

  18. The ethics of a co-regulatory model for farm animal welfare research

    | Contributor(s):: Phillips, C. J. C., Petherick, J. C.

    Standards for farm animal welfare are variously managed at a national level by government-led regulatory control, by consumer-led welfare economics and co-regulated control in a partnership between industry and government. In the latter case the control of research to support animal welfare...

  19. Artificial weaning of calves: benefits and costs

    | Contributor(s):: Reinhardt, V.

    Evidence indicates that allowing beef calves to stay in the maternal herd beyond the age of natural weaning promotes animal welfare and may enhance the cows' natural reproductive potential.

  20. Handling, electric goad, and head restraint: effects on calves' behavior

    | Contributor(s):: Goonewardene, L. A., Price, M. A., Stookey, J. M., Day, P. A., Minchau, G.

    96 weaned calves (48 bulls and 48 heifers) were allocated in a 2 x 2 x 2 arrangement to 3 treatments each with 2 levels: calves handled every 10 days or 20 days; an electric goad used or not used; and head gate restrained or not restrained. Behaviour responses were measured by 5 incremental...
