  1. 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...

  2. 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...

  3. Effects of early experience and alternative feeds on medusahead (Taeniatherum caput-medusae ssp. asperum) intake by sheep

    Contributor(s):: Montes-Sánchez, Juan J., Villalba, Juan J.

    The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep. The study involved two experiments of 10 days each. During Experiment 1, 29...

  4. Using a three-axis accelerometer to identify and classify sheep behaviour at pasture

    Contributor(s):: Alvarenga, F. A. P., Borges, I., Palkovič, L., Rodina, J., Oddy, V. H., Dobos, R. C.

    Identifying and classifying feeding behaviour in free-ranging ruminants will help improve efficiency of animal production. Another potential benefit would be in understanding the role behaviour has in determining heritability of methane measurement. The aim of this study was to determine the...

  5. Location of supplementary feed and water troughs on the sward affects movement and spatial distribution of Brahman cattle (Bos indicus)

    Contributor(s):: Solano, Jaime, Averós, Xavier, Clemente, Neftalí, Aguirre, Virginio, Estevez, Inma, Orihuela, Agustín

    The grazing dynamics of animals differ depending on whether they are raised on rangeland or sward areas. Grazing patterns of cattle raised on rangeland can be modified by the location of supplement feed and water troughs. However, no information about the use of this strategy is available for...

  6. Influence of off-stream watering systems on cattle behaviour adjacent to Lower Little Bow River in Southern Alberta

    Contributor(s):: Miller, J. J., Curtis, T., Rogness, D., Willms, W. D., Chanasyk, D. S.

    Off-stream waterers (OSWs) located in upland pastures may be effective in reducing livestock impacts on riparian areas and rivers, but little research has been conducted on the impact of OSWs located closer to rivers. We studied cattle behaviour over four years (2012-2015) for a portable OSW at...

  7. Brazilian Citizens: Expectations Regarding Dairy Cattle Welfare and Awareness of Contentious Practices

    Contributor(s):: Clarissa S. Cardoso, Marina A.G. von Keyserlingk, Marie Jose Hotzel

    The primary aim of this study was to explore attitudes of urban Brazilian citizens about dairy production. A secondary aim was to determine their knowledge and attitudes about four potentially contentious routine dairy cattle management practices: early cow-calf separation; zero-grazing; culling...

  8. 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...

  9. A modeling approach for estimating seasonal dietary preferences of goats in a Mediterranean Quercus frainetto-Juniperus oxycedrus woodland

    Contributor(s):: Manousidis, T., Malesios, C., Kyriazopoulos, A. P., Parissi, Z. M., Abraham, E. M., Abas, Z.

    Goats are characterized as selective feeders due to their specific feeding behavior, thus the study of their seasonal preferences in a Mediterranean oak-juniper ecosystem is of great interest. The current research was conducted in an open oak forest in Megalo Dereio region, northeastern Greece...

  10. Population trends of resident and migratory Canada geese in relation to strikes with civil aircraft

    Contributor(s):: Dolbeer, Richard A., Seubert, John L., Begier, Michael J.

  11. Evaluation of foliar sprays to reduce crop damage by Canada geese

    Contributor(s):: Dieter, Charles D., Warner, Cody S., Ren, Curiong

  12. Vitals rates and seasonal movements of two isolated greater sage-grouse populations in Utah's West Desert

    Contributor(s):: Robinson, Jason D., Messmer, Terry A.

  13. Occurrence and success of greater sage-grouse broods in relation to insect-vegetation community gradients

    Contributor(s):: Harju, Seth M., Olson, Chad V., Foy-Martin, Lisa, Webb, Stephen L., Dzialak, Matthew R., Winstead, Jeffrey B., Hayden-Wing, Larry D.

  14. Rodent population management at Kansas City International Airport

    Contributor(s):: Witmer, G. W.

  15. Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda

    Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.

    This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...

  16. 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...

  17. Mother-young behaviours at lambing in grazing ewes: effects of lamb sex and food restriction in pregnancy

    Contributor(s):: Freitas-De-Melo, A., Ungerfeld, R., Hotzel, M. J., Abud, M. J., Alvarez-Oxiley, A., Orihuela, A., Damian, J. P., Perez-Clariget, R.

    This study investigated whether the level of pasture allowance from before conception until late pregnancy affects ewe-lamb behaviours at birth, and if those behaviours differ according to the sex of the lambs. We performed two experiments, in which 96 ewes were assigned to one of two nutritional...

  18. The effect of four different feeding regimes on rabbit behaviour

    Contributor(s):: Prebble, J. L., Langford, F. M., Shaw, D. J., Meredith, A. L.

    Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the...

  19. Daily grazing time of dairy cows is recorded accurately using the Lifecorder Plus device

    Contributor(s):: Delagarde, R., Lamberton, P.

    Accurate estimation of daily grazing time and nycthemeral grazing pattern in ruminant nutrition research may result in a better understanding of sward-animal interactions and of the behavioural constraints affecting daily intake at pasture. Portable devices which automatically record grazing...

  20. 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...
