  3. Herd-Level on-Farm Mortality in Extensively Managed Beef Herds

    Contributor(s):: Mõtus, Kerli, Niine, Tarmo, Viltrop, Arvo, Emanuelson, Ulf

    The herd on-farm mortality rate is an indicator of herd animal health and welfare status. The aim of the present study was to describe herd-level on-farm mortality rates and to identify risk factors that contribute to high herd mortality rates. Online or postal questionnaires were sent to 676...

  4. 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...

  5. Using qualitative behaviour assessment to explore the link between stockperson behaviour and dairy calf behaviour

    Contributor(s):: Ellingsen, Kristian, Coleman, Grahame J., Lund, Vonne, Mejdell, Cecilie M.

    Dairy farming usually implies close and frequent contact between the stockperson and the animals. A good human–animal relationship (HAR) is therefore essential for good animal welfare. To fully understand the quality of the HAR both the stockperson behaviour and the animals’ reaction to the...

  6. 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...

  7. 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...

  8. Operant conditioning of urination by calves

    Contributor(s):: Vaughan, Alison, de Passillé, Anne Marie, Stookey, Joseph, Rushen, Jeffrey

    The accumulation of faeces and urine in dairy barns is a cause of cattle and human health concerns and environmental problems. It is usually assumed that cattle are not capable of controlling defecation and urination. We tested whether calves could be taught to urinate in a location using either...

  9. 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,...

  10. 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...

  11. Predicting sleep and lying time of calves with a support vector machine classifier using accelerometer data

    Contributor(s):: Hokkanen, Ann-Helena, Hänninen, Laura, Tiusanen, Johannes, Pastell, Matti

    Sleep is essential to calves, but to date the only possibilities for measuring sleep in cattle production systems use ambulatory EEG or validated sleeping behavior assessments. We developed a small, neck-based, wireless accelerometer system for measuring the sleep and lying time of calves. We...

  12. 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...

  13. Individual differences in calf defence patterns in Red Angus beef cows

    Contributor(s):: Flörcke, Cornelia, Engle, Terry E., Grandin, Temple, Deesing, Mark J.

    The objective of this study was to evaluate differences in individual calf defence behaviour patterns and maternal protective behaviour of beef cows 24h after calving. A single herd was observed on an extensive ranch in Colorado, USA. A total of 341 cow–calf pairs (95% Red Angus and 5%...

  14. Gentle touching in early life reduces avoidance distance and slaughter stress in beef cattle

    Contributor(s):: Probst, Johanna K., Spengler Neff, Anet, Leiber, Florian, Kreuzer, Michael, Hillmann, Edna

    This study investigated the effect of gentle touching applied during the early life of suckler beef calves on avoidance distance on-farm and stress reactions at the abattoir. Twenty-seven Limousin crossbred calves were assigned to a treatment (n=13) or a control group (n=14) balanced by sex and...

  15. Effect of rectal or intravenous tramadol on the incidence of pain-related behaviour after disbudding calves with caustic paste

    Contributor(s):: Braz, Maria, Carreira, Maria, Carolino, Nuno, Rodrigues, Tania, Stilwell, George

    To evaluate the efficacy of tramadol (suppositories or intravenous) in alleviating pain after caustic paste disbudding, two behaviour-assessing methods were used during the first hour post-disbudding: the objective recording of four pain-related behaviours and the subjective scoring pain on a...

  16. 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;...

  17. 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....

  18. 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...

  19. 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, Laura E., Bokkers, Eddie A. M., Engel, Bas, Gerrits, Walter J. J., Berends, Harma, van Reenen, Cornelis G.

    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 hence...

  20. An assessment of behavioural syndromes in rangeland-raised beef cattle

    Contributor(s):: Wesley, Robert L., Cibils, Andrés F., Mulliniks, J. Travis, Pollak, Emily R., Petersen, Mark K., Fredrickson, Ed L.

    Individuals in most animal groups exhibit consistent behavioural differences across situations or over time known as behavioural syndromes. We conducted a study with a herd of young rangeland-raised cows to determine whether animals exhibited consistent differences in foraging behaviours across...
