  1. 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...

  2. 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...

  3. 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...

  4. 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,...

  5. 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...

  6. 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...

  7. 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;...

  8. 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....

  9. 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...

  10. 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...

  11. Assessing calf play behavior in an arena test

    Contributor(s):: Mintline, Erin M., Wood, Sara L., de Passillé, Anne Marie, Rushen, Jeffrey, Tucker, Cassandra B.

    The use of play as an indicator of animal welfare shows promise, and an arena test is one method used to assess how different procedures or housing conditions affect calves’ motivation to perform locomotor play. However, it is unclear if this test reflects play in the home pen. In addition, the...

  12. Addressing the pain associated with disbudding and dehorning in cattle

    Contributor(s):: Stafford, Kevin J., Mellor, David J.

    The pain caused by disbudding or dehorning of cattle and its alleviation may be assessed by behavioural, physiological and production responses. Disbudding can be carried out by cautery or the application of a chemical paste. Cautery disbudding and amputation dehorning stimulate definite pain...

  13. 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...

  14. Barren diets increase wakeful inactivity in calves

    Contributor(s):: Webb, Laura E., Engel, Bas, van Reenen, Kees, Bokkers, Eddie A. M.

    Inactivity is a vastly understudied behavioural category, which may reflect positive or negative affective states in captive or domesticated animals. Increased inactivity in barren-housed animals, in combination with an increased or decreased interest in stimuli, e.g. novel objects, can indicate...

  15. Effects of separation time on behavioral and physiological characteristics of Brahman cows and their calves

    Contributor(s):: Pérez-Torres, Libia, Orihuela, Agustín, Corro, Manuel, Rubio, Ivette, Alonso, Miguel A., Galina, Carlos S.

    The aim of this study was to investigate the effects of separation time on behavioral and physiological characteristics of Brahman cows and their calves. Thirty Brahman cow-calf pairs raised under extensive conditions were randomly assigned to one of three temporary weaning duration:...

  16. Gentle interactions decrease the fear of humans in dairy heifers independently of early experience of stroking

    Contributor(s):: Lürzel, Stephanie, Windschnurer, Ines, Futschik, Andreas, Waiblinger, Susanne

    The relationship of farmed animals with humans has important implications for animal welfare and productivity. To investigate the short- and long-term effect of gentle interactions (stroking, talking in a gentle voice) during different life stages on the fear of humans, we tested heifers that had...

  17. Effect of portion size and milk flow on the use of a milk feeder and the development of cross-sucking in dairy calves

    Contributor(s):: Nielsen, Per Peetz, Jensen, Margit Bak, Halekoh, Ulrich, Lidfors, Lena

    This study aimed to investigate whether reducing the milk flow and increasing the milk portion size of a computer-controlled milk feeder would lead to less cross-sucking and fewer unrewarded feeder visits in dairy calves. Five groups, each with 9 or 10 calves (n = 48), were housed in pens with...

  18. 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...

  19. A Decade of Progress toward Ending the Intensive Confinement of Farm Animals in the United States

    Contributor(s):: Sara Shields, Paul Shapiro, Andrew Rowan

    In this paper, the Humane Society of the United States (HSUS) farm animal protection work over the preceding decade is described from the perspective of the organization. Prior to 2002, there were few legal protections for animals on the farm, and in 2005, a new campaign at the HSUS began to...

  20. 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...
