Predicting cattle grazing distributions: an agent-based modeling approach
An agent-based model was designed which simulates foraging of yearling steers grazing in the short grass steppe region of Colorado, USA. Eleven hypotheses were analyzed that address different aspects of foraging behavior. Models tracked the grazing distributions of simulated steers, as well as their time spent grazing and amount of forage consumed. Model output was validated against grazing distributions and time spent grazing of real steers, observed using GPS-collars. Results indicate that in pastures containing sufficient heterogeneity, steers exhibit selective grazing behaviors in response ...
