  • Development of dairy cow lumen model and behavioral modeling using hidden semi-Markov model

抄録

<p>In dairy farming, it is required to raise animals in consideration of animal welfare. In addition, it is also required to increase the amount of milk, which is the product. For these realizations, it is necessary for humans to intervene theoretically and cows to be relaxed. Therefore, we defined an index of satiety from the stomach contents of dairy cows. In addition, a behavioral model was created using a hidden semi-Markov model. By introducing an index of satiety and creating a behavior model, it was confirmed that the behavior model changed appropriately for each satiety degree. When hungry, it transitioned to eating behavior, and when full, it transitioned to non-eating behavior. We were able to create a model that matches the actual behavior.</p>
