  5. Effects of grazing muzzles on behavior, voluntary exercise, and physiological stress of miniature horses housed in a herd

    Contributor(s):: Davis, Kristina M., Iwaniuk, Marie E., Dennis, Rachel L., Harris, Patricia A., Burk, Amy O.

    Grazing muzzles are a popular and effective management tool used to help prevent weight gain in obese-prone equids. Concerns have been raised over their possible negative impact on horse well-being as muzzles may interfere with normal grazing and social behaviors. The objective of this study was...

  6. Foraging Behavior Patterns of Sheep and Horses Under a Mixed Species Grazing System

    Contributor(s):: Patkowski, Krzysztof, Pluta, Michał, Lipiec, Antoni, Greguła-Kania, Monika, Gruszecki, Tomasz M.

    The research objective was to assess the behavior patterns of the Polish Konik horse breed and the Uhruska variety of the Polish Lowland Sheep breed under a mixed-grazing system, and their relationship with climatic factors. The observation included 4 adult horses, 27 ewes with lambs and 10...

  7. The effect of a view to the surroundings and microclimate variables on use of a loafing area in housed dairy cattle

    Contributor(s):: Haskell, Marie J., Masłowska, Katarzyna, Bell, David J., Roberts, David J., Langford, Fritha M.

    There is concern that cows that are continuously housed year-round may lack the opportunity to express a full range of natural behaviour. Providing these cows with a loafing or exercise area may allow them the space to express a greater behavioural repertoire. Little is known about the factors...

  8. Different problem-solving strategies in dogs diagnosed with anxiety-related disorders and control dogs in an unsolvable task paradigm

    Contributor(s):: Passalacqua, Chiara, Marshall-Pescini, Sarah, Merola, Isabella, Palestrini, Clara, Previde, Emanuela Prato

    In humans and in other animal species anxiety-related problems are associated with poor performance in different abilities ranging from decision-making, visual attention, learning and memory. Despite the increasing number of dogs showing anxiety-related problems, the relationship between...

  9. Cattle habitat selection and associated habitat characteristics under free-range grazing within heterogeneous Montane rangelands of Alberta

    Contributor(s):: Kaufmann, Jillian, Bork, Edward W., Blenis, Peter V., Alexander, Michael J.

    The integration of multiple uses on public rangeland requires reliable information on patterns of livestock use. We used GPS data and field plot utilization indices to examine cattle selection at the landscape and patch levels, respectively, within a heterogeneous Montane environment of SW...

  10. Can the location of cattle be managed using broadcast audio cues?

    Contributor(s):: Umstatter, Christina, Brocklehurst, Sarah, Ross, David W., Haskell, Marie J.

    Fences are crucial for successful grazing management of livestock. However, conventional fencing is expensive and lacks spatial flexibility. To date, this flexibility has been provided by electric fences, but these are not always efficient to erect and move and are not suitable for all locations....

  11. Behavioural mechanisms of intake rate by heifers grazing swards of contrasting structures

    Contributor(s):: Mezzalira, Jean Carlos, De Faccio Carvalho, Paulo César, Fonseca, Lidiane, Bremm, Carolina, Cangiano, Carlos, Gonda, Horacio Leandro, Laca, Emilio Andrés

    The relationship between herbage intake by herbivores and herbage available depends on the interaction between sward structure and animal behaviour. This relationship is a crucial component determining the stability, function and productivity of grazing systems. The present study aims at...

  12. Automatic registration of grazing behaviour in dairy cows using 3D activity loggers

    Contributor(s):: Nielsen, Per Peetz

    Automated systems for monitoring behaviour of cows within dairy production are increasing and developments in technology provide new opportunities in this area. This study aimed to validate the use of a 3D activity logger (HOBO® Pendant G Data Logger), that registers the cow's head positions...

  13. Training methods for introducing cows to a pasture-based automatic milking system

    Contributor(s):: Jago, J., Kerrisk, K.

    Training cows to use an automatic milking system (AMS) is an important process as this method of milking depends on cows voluntarily using the AMS. This study examined two levels of training before calving on the behaviour of cows and heifers in an extensive pasture-based AMS. Animals received...

  14. Grazing behavior of sheep at different stocking rates in the Inner Mongolian steppe, China

    Contributor(s):: Lin, Lijun, Dickhoefer, Uta, Müller, Katrin, Wurina,, Susenbeth, Andreas

    In free-ranging or grazing animals, physical activity can account for a substantial proportion of their total energy requirement with considerable consequences for animals at low production level. This study evaluated the effect of grazing intensity (GI) on behavior and walking distance of sheep...

  15. Foraging behaviour of beef heifers and ewes in natural grasslands with distinct proportions of tussocks

    Contributor(s):: Bremm, Carolina, Laca, Emilio Andrés, Fonseca, Lidiane, Mezzalira, Jean Carlos, Elejalde, Denise Adelaide Gomes, Gonda, Horacio Leandro, Carvalho, Paulo César de Faccio

    In natural grasslands, plant species preferred by grazing animals are intermixed with less preferred species. We hypothesise that increasing proportion of Eragrostis plana Nees tussocks, a non-preferred diet item in natural grassland, will constrain the accessibility of the preferred diet item...

  16. Eliminative behaviour of dairy cows at pasture

    Contributor(s):: Whistance, Lindsay Kay, Sinclair, Liam A., Arney, David Richard, Phillips, Clive Julian Christie

    Despite a strong avoidance of grazing near dung patches, cattle have traditionally been considered not to avoid bodily contact with faeces, regardless of any risk of disease. Little is understood of the behaviour of pasture-kept dairy cows at the time of defaecation and therefore, the eliminative...

  17. Defaecation and urination behaviour in beef cattle grazing semi-natural grassland

    Contributor(s):: Orr, Robert J., Griffith, Bruce A., Champion, Robert A., Cook, James E.

    There is increasing global interest in the extent to which multi-species grasslands containing increased plant diversity compared with improved grasslands can also deliver higher resource protection. The objective of this experiment was to examine nutrient returns via faeces and urine by...

  18. 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...

  19. Microhabitat selection of free-ranging beef cattle in south-boreal forest

    Contributor(s):: Spedener, Mélanie, Tofastrud, Morten, Devineau, Olivier, Zimmermann, Barbara

    Cattle released for summer grazing in south-boreal forest are free to select among a broad range of habitats. The goal of this study was to identify the factors influencing the microhabitat selection of such free-ranging beef cattle, for grazing and resting. We equipped sixteen female adult cows...

  20. Associations between precision sensor data with productivity, health and welfare indicator traits in native black and white dual-purpose cattle under grazing conditions

    Contributor(s):: Jaeger, Maria, Brügemann, Kerstin, Brandt, Horst, König, Sven

    The aim of the study was to analyse the relationships between conventional production as well as subjectively scored welfare assessment traits with longitudinal sensor measurements (i.e., behavioural activity traits) of dual-purpose cattle kept in grazing systems. Such aim implies getting...
