    One of the challenges for cattle management under extensive grazing systems is understanding how time spent in different individual activities is affected by factors like microclimate and forage quality and availability. The goal of this study is to understand how different tree densities and...

  7. Foraging behaviour of gestating sows on pasture and damages to vegetation cover are influenced by restriction of concentrate feed

    | Contributor(s):: Aubé, Lydiane, Guay, Frédéric, Bergeron, Renée, Théau, Jérôme, Devillers, Nicolas

    One of the main challenges of outdoor pig production systems is their potential environmental impact due to direct deposition of pigs’ excreta on the land that can lead to nitrate leaching. However, plants can recycle nutrients, and a sufficient vegetation cover can mitigate adverse...

  8. Effects of Grazing in a Sown Pasture with Forestland on the Health of Japanese Black Cows as Evaluated by Multiple Indicators

    | Contributor(s):: Nakajima, Noriaki, Doi, Kazuya, Tamiya, Sae, Yayota, Masato

    The objective of the present study was to evaluate the effects of extensive grazingin a sown pasture with forestland on the health of beef cows by measuring multiple indicators. Ten Japanese Black beef cows were used in this experiment. Five of the ten cows were grazed for two months on a 1.8 ha...

  9. Threshold values to discriminate grazing activity of dairy cows by an uni-axial accelerometer as affected by grazing season and herbage mass

    | Contributor(s):: Piña, Luis F., Balocchi, Oscar A., Keim, Juan P., Pulido, Rubén G., Rosas, Felipe

    Recording grazing time is important because the time allocated for each grazing event is one of the limitations to achieving high intake levels. Grazing time can be measured via visual observation or, more recently, by devices calibrated for this purpose. The Kenz Lifecorder Plus (Suzuken Co....

  10. 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...

  11. 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...

  12. 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...

  13. 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...
