Exploring and forecasting farm animal feeding behaviors yields valuable insights into nutritional needs and medication dosages, such as antibiotics administered to livestock. Utilizing mathematical models, we can simulate the pharmacokinetic profile of drugs within a swine population. This simulation aids in preventing treatment failures and mitigating adverse environmental and health impacts, while also enhancing the efficiency of resource usage (energy and water) on farms. Our research focused on constructing a model that accurately depicts the feeding habits of purebred Duroc pigs. Data captured by automated feeders provided detailed records of feed consumption and visitation timings for pigs identified with ear chips. Through statistical analysis of these feeding patterns, we derived a deeper understanding of animal behavior, informed by empirical data from pig farms in Catalonia.
