  1. A Comparison of Walking Rates Between Wild and Zoo African Elephants

    Contributor(s):: Miller, Lance J., Chase, Michael J., Hacker, Charlotte E.

    With increased scrutiny surrounding the welfare of elephants in zoological institutions, it is important to have empirical evidence on their current welfare status. If elephants are not receiving adequate exercise, it could lead to obesity, which can lead to many issues including acyclicity and...

  2. 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...

  3. 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...

  4. Foraging paths through vegetation patches for beef cattle in semi-natural pastures

    Contributor(s):: Orr, Robert J., Tozer, Katherine N., Griffith, Bruce A., Champion, Robert A., Cook, James E., Rutter, Steven Mark

    Grazing semi-natural grasslands may enhance their wildlife faunal diversity and abundance by modifying the plant species composition through exploiting the dietary choices of the domestic livestock, yet diet preferences in these grasslands are often poorly understood. We therefore investigated...

  5. The effects of GPS collars on African elephant (Loxodonta africana) behavior at the San Diego Zoo Safari Park

    Contributor(s):: Horback, Kristina Marie, Miller, Lance Joseph, Andrews, Jeffrey, Kuczaj, Stanley Abraham, Anderson, Matthew

    The use of tracking devices (e.g., VHF radio collars, GPS collars, ear transmitters) enables researchers to assess activity budgets, species-specific movement patterns, effects of environmental enrichment, and exercise levels in zoo animals. The fundamental assumption in these studies of tagged...

  6. 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...

  7. Spatial and temporal activity of cattle grazing in Mediterranean oak woodland

    Contributor(s):: Schoenbaum, Iris, Kigel, Jaime, Ungar, Eugene D., Dolev, Amit, Henkin, Zalmen

    We examined the temporal and spatial variation patterns of the grazing activity of free-ranging cattle in Mediterranean oak woodland in the Western Galilee, Israel, as affected by seasonal and management factors. The vegetation is dominated by scrub-oak woodland (Quercus calliprinos Webb.),...

  8. The effects of global navigation satellite system (GNSS) collars on cattle (Bos taurus) behaviour

    Contributor(s):: Manning, Jaime K., Cronin, Greg M., González, Luciano A., Hall, Evelyn J. S., Merchant, Andrew, Ingram, Lachlan J.

    The use of Global Navigation Satellite System (GNSS) collars has become an increasingly important research tool to study the behaviour of domestic livestock species in grazing conditions. However, relatively little is known about the effects on livestock behaviour of livestock “wearing” such...

  9. A two-stage method to approach weaning stress in horses using a physical barrier to prevent nursing

    Contributor(s):: Merkies, Katrina, DuBois, Cordelie, Marshall, Kaitlyn, Parois, Severine, Graham, Laura, Haley, Derek

    Many domestic horses are weaned through abrupt physical separation of the foal and mare. Deviations from normal behaviours testify that this abrupt method has an adverse effect on the well-being of both mares and foals. To reduce negative changes in behaviour and physiology induced by weaning, a...

  10. Are the livestock guarding dogs where they are supposed to be?

    Contributor(s):: Zingaro, Margherita, Salvatori, Valeria, Vielmi, Luisa, Boitani, Luigi

    In many parts of the world, livestock guarding dogs (LGDs) are considered one of the most powerful prevention tools against carnivore predation on domestic animals, but how they behave when left unsupervised with their flock on pastures is mostly unknown. We monitored 29 LGDs with GPS (Global...

  11. Movement and home range of owned free-roaming male dogs in Puerto Natales, Chile

    Contributor(s):: Pérez, Guillermo E., Conte, Annamaria, Garde, Elena J., Messori, Stefano, Vanderstichel, Raphael, Serpell, James

    Free-roaming dogs (FRDs) pose a significant health threat to humans, other animals and the environment. Yet, the effects of their movements and habitat use within cities and adjacent rural areas are poorly known, especially in relation to predation and the transmission of diseases that can impact...

  12. Livestock guarding behaviour of Kangal dogs in their native habitat

    Contributor(s):: Akyazi, Ibrahim, Ograk, Yusuf Ziya, Eraslan, Evren, Arslan, Murat, Matur, Erdal

    Kangal Shepherd Dog is one of the endemic large dog breeds in Anatolia, Turkey. It is bred in different regions of Turkey as well as in different countries as a livestock guarding dog (LGD). Being one of the most popular and common LGD breeds, basic behavioural traits and the effectiveness of...

  13. Tech-Savvy Beef Cattle? How Heifers Respond to Moving Virtual Fence Lines

    Contributor(s):: Dana L. M. Campbell, Jim M. Lea, William J. Farrer, Sally J. Haynes, Caroline Lee

    Global Positioning System (GPS)-based virtual fences offer the potential to improve the management of grazing animals. Prototype collar devices utilising patented virtual fencing algorithms were placed on six Angus heifers in a 6.15 hectare paddock. After a “no fence” period,...

  14. The use of differentially corrected global positioning system to monitor activities of cattle at pasture

    Contributor(s):: Schlecht, E., Hulsebusch, C., Mahler, F., Becker, K.

    Global positioning system (GPS) technology is increasingly applied in livestock science to monitor pasture use and tracking routes, and is often combined with equipment for monitoring animal activity. As GPS data are referenced in time and space, it is hypothesised that parameters derived there...

  15. A note on using a laser-based technique for recording of behaviour and location of free-ranging animals

    Contributor(s):: Fehmi, J. S., Laca, E. A.

    We developed a precise, remote (up to 300 m) observation system to record animal location and behaviour that requires no animal handling or disruption of the normal environment. Our system, combining a survey laser and a laptop, also allows recording of observed animal behaviour from seconds to...

  16. Manipulating cattle distribution with salt and water in large arid-land pastures: a GPS/GIS assessment

    Contributor(s):: Ganskopp, D.

    Several of the problems associated with grazing animals in extensive settings are related to their uneven patterns of use across the landscape. After fencing, water and salt are two of the most frequently used tools for affecting cattle distribution in extensive settings. Cattle are attracted to...
