  7. The Welfare Quality (R) assessment protocol: how can it be adapted to family farming dual purpose cattle raised under extensive systems in tropical conditions?

    Contributor(s):: Hernandez, A., Berg, C., Eriksson, S., Edstam, L., Orihuela, A., Leon, H., Galina, C.

  8. What do calves choose to eat and how do preferences affect behaviour?

    Contributor(s):: Webb, Laura E., Engel, Bas, Berends, Harma, van Reenen, Cornelis G., Gerrits, Walter J. J., de Boer, Imke J. M., Bokkers, Eddie A. M.

    Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the ‘average calf’. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...

  9. The use of GPS data to identify calving behaviour of farmed red deer hinds: Proof of concept for intensively managed hinds

    Contributor(s):: Asher, G. W., Wall, A. J., O’Neill, K. T., Littlejohn, R. P., Bryant, A., Cox, N.

    This study investigated the utility of GPS data for assigning individual calving dates and times for red deer hinds based on already known generalised movement patterns around parturition. Nineteen hinds expected to calve in early November were fitted with GPS neck collars two weeks before...

  10. Rearing substrate and space allowance influences locomotor play behaviour of dairy calves in an arena test

    Contributor(s):: Sutherland, Mhairi A., Worth, Gemma M., Schütz, Karin E., Stewart, Mairi

    The aim of this study was to investigate the effect of rearing substrate and space allowance in the home environment on the motivation of dairy calves to perform locomotor play in an arena test. At 1wk of age, 72 calves were moved into one of 18 experimental pens (n=4 calves/pen) where they...

  11. Effects of two substrate types on the behaviour, cleanliness and thermoregulation of dairy calves

    Contributor(s):: Sutherland, Mhairi A., Stewart, Mairi, Schütz, Karin E.

    The use of river stones as a substrate to rear calves on is a management practice that is becoming more common in parts of New Zealand where more traditional substrate types, such as sawdust, can be difficult and/or expensive to obtain. A study was conducted to compare the behaviour, cleanliness,...

  12. Does housing nulliparous dairy cows with multiparous animals prior to calving influence welfare- and production-related parameters after calving?

    Contributor(s):: Boyle, Alastair R., Ferris, Conrad P., O’Connell, Niamh E.

    The aim of this experiment was to determine the effects of housing nulliparous cows with non-lactating multiparous cows during the pre-calving period, on welfare and production-related parameters during the post calving period. Twenty nulliparous Holstein Friesian dairy cattle were assigned to...

  13. Parturition progress and behaviours in dairy cows with calving difficulty

    Contributor(s):: Barrier, Alice C., Haskell, Marie J., Macrae, Alastair I., Dwyer, Cathy M.

    The welfare of dairy cows and their calves is compromised following a difficult calving. A better understanding of what happens during a difficult calving is needed to help prevent and alleviate adverse consequences through early diagnosis and/or pain mitigation. The objectives of this study were...

  14. Comparison of methods to quantify the number of bites in calves grazing winter oats with different sward heights

    Contributor(s):: Nadin, Laura B., Chopa, Federico Sánchez, Gibb, Malcolm J., Trindade, Júlio Kuhn da, Amaral, Glaucia Azevedo do, de Faccio Carvalho, Paulo C., Gonda, Horacio L.

    The requirement to measure the constituents of ingestive behaviour in grazing ruminants, such as the number and type of jaw movements, is essential for understanding the herbage intake process. In this experiment, three methods of recording grazing behaviour were compared: visual observation (VO;...

  15. Changes in the behaviour of dairy cows during the 24h before normal calving compared with behaviour during late pregnancy

    Contributor(s):: Miedema, Hanna M., Cockram, Michael S., Dwyer, Cathy M., Macrae, Alastair I.

    Dairy cows require individual monitoring around the time of calving to identify any calving difficulties or health problems as early as possible. To assist with the monitoring of parturition, it would be beneficial to understand the behaviour of dairy cows that is associated with normal calving....

  16. Behavioural predictors of the start of normal and dystocic calving in dairy cows and heifers

    Contributor(s):: Miedema, Hanna M., Cockram, Michael S., Dwyer, Cathy M., Macrae, Alastair I.

    The individual monitoring of dairy cows around the time of calving is important to identify calving difficulties or health problems as early as possible. This study aims to identify whether there are differences in the behaviour before calving, between heifers and cows, and between those that are...

  17. A single dose of ketoprofen in the immediate postpartum period has the potential to improve dairy calf welfare in the first 48 h of life

    Contributor(s):: Gladden, Nicola, Ellis, Kathryn, Martin, Jessica, Viora, Lorenzo, McKeegan, Dorothy

    The welfare impact of birth on newborn calves has rarely been studied. Dystocia in particular may have significant welfare costs for calves. While analgesia is sometimes provided to calves born to difficult parturition by veterinary surgeons in practice, it is not known if this is actually...

  18. Impacts of shade on physiological and behavioural pattern of Dehong buffalo calves under high temperature

    Contributor(s):: Gu, Zhaobing, Yang, Shuli, Leng, Jing, Xu, Shaohong, Tang, Shoukun, Liu, Chuanbin, Gao, Yajun, Mao, Huaming

    Shade shelter is widely used to reduce heat load for farm animals, but little research focus on the cooling effects for Dehong buffalo calves. The aim of this experiment was to evaluate the impacts of shade cooling on the physiological and behavioural parameters for Dehong buffalo calves. Shade...

  19. 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...

  20. What is the relationship between level of infection and 'sickness behaviour' in cattle?
