  1. 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...

  2. 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...

  3. 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...

  4. Behavioral patterns of (co-)grazing cattle and sheep on swards differing in plant diversity

    Contributor(s):: Cuchillo Hilario, Mario, Wrage-Mönnig, Nicole, Isselstein, Johannes

    Both botanical composition and the presence of additional grazer species may modify the grazing efficiency and ingestive behavior of ruminants. However, at present, potential effects of interactions between sward diversity and presence of multiple animal species on the grazing behavior of cattle...

  5. Effects of visual obstruction, prey resources, and satiety on bird use of simulated airport grasslands

    Contributor(s):: Blackwell, Bradley F., Seamans, Thomas W., Linnell, Kimberly, Kutschbach-Brohl, Lisa, DeVault, Travis L.

    Grasslands represent 39%–50% of U.S. airport properties, and a recent management framework recommended exploiting both antipredator behaviours and food resources in airport grasslands to curb use by birds considered hazardous to aviation safety. We evaluated framework predictions empirically by...

  6. Human-Managed vs. Natural Grazing Systems: Exploring Effects of Livestock and Wildlife Grazing at Multiple Scales

    Contributor(s):: Megan Esther McSherry

    Grazing by large herbivores is the most prevalent land use on grassland ecosystems, which cover greater than 40% of the earth's land surface and provide critical ecological and economic benefits. As such, understanding how grazing impacts different aspects of the ecosystem is of especially...

  7. Relationship between spatial distribution of sika deer-train collisions and sika deer movement in Japan

    Contributor(s):: Soga, Akinao, Hamasaki, Shin-ichiro, Yokoyama, Noriko, Sakai, Toshiyuki, Kaji, Koichi

  8. Spatial and temporal analysis of factors associated with urban deer-vehicle collisions

    Contributor(s):: McCance, Erin C., Baydack, Richard K., Walker, David J., Leask, Derek N.

  9. Characteristics and distribution of livestock losses caused by wild carnivores in Maasai Steppe of northern Tanzania

    Contributor(s):: Mponzi, Batistino P., Lepczyk, Christopher A., Kissui, Bernard M.

  10. Flight distance and reaction to fawn handling are greater in high- than in low-ranked pampas deer ( Ozotoceros bezoarticus) females

    Contributor(s):: Ungerfeld, R., Morales-Pineyrua, J. T., Freitas-de-Melo, A.

    The flight distance from humans and the reaction of the mother to human handling of their offspring are measures that can be used to assess the quality of the human-animal relationship which could vary according to animals' position in a group. The objective was to determine if the flight...

  11. Hormonal and behavioural stress responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus)

    Contributor(s):: Munerato, M. S., Marques, J. A., Caulkettt, N. A., Tomas, W. M., Zanetti, E. S., Trovati, R. G., Pereira, G. T., Palme, R.

    This study evaluated the short-term hormonal and behavioural responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus). Twenty adult deer (eleven females and nine males) were captured in the South Pantanal wetland (Brazil) and equipped with VHF...

  12. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  13. Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes

    Contributor(s):: Cornelissen, P., Vulink, J. T.

    For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...

  14. Accommodating Cattle: British Columbia 's " Wars" w ith Grasshoppers and "Wild Horses"

    Contributor(s):: Thistle, John

  15. Environmental duty of care: from ethical principle towards a code of practice for the grazing industry in Queensland (Australia)

    Contributor(s):: Greiner, R.

    Among the options of government for reducing negative environmental externalities from agriculture is the institution of a polluter statutory liability. An environmental duty of care imposes a statutory liability on agents who interact with the environment to avoid causing environmental harm....

  16. Management, health, and abnormal behaviors of horses: a survey in small equestrian centers in Brazil

    Contributor(s):: Leme, D. P., Parsekian, A. B. H., Kanaan, V., Hotzel, M. J.

    Care conditions of horses housed in small equestrian establishments and the occurrence of health and behavioral problems were assessed in 197 animals. Based on questionnaires and direct observations of the animals, it was noted that 8% of all animals were fed exclusively on pasture, whereas 92%...

  17. Observing lame sheep: evaluating test agreement between group-level and individual animal methods of assessment

    Contributor(s):: Phythian, C. J., Cripps, P. C., Grove-White, D., Jones, P. H., Michalopoulou, E., Duncan, J. S.

    Full-text: Available

    | Contributor(s):: Spooner, J. M., Schuppli, C. A., Fraser, D.

    As part of a larger project to determine if there are animal-welfare-related values shared by some commercial food–animal producers and non-producers in Canada, open-ended, semi-structured interviews were conducted to elicit opinions about animal welfare among 24 urban and rural residents...
