Satellite-Based Decision Support Tools to Assist Grazing Cattle Production.

The article focuses on recent advances in modeling and technology applications in animal science, particularly in poultry nutrition, grazing cattle production, and precision livestock farming. It highlights challenges in poultry modeling, including the need for increased education and integration of models with data. Satellite-based decision support tools for grazing cattle utilize remote sensing technologies, such as optical sensors and active sensors like Synthetic Aperture Radar (SAR) and Light Detection and Ranging (LIDAR), combined with machine learning algorithms to monitor grassland biomass and nutritional status for improved pasture management. Additionally, the development of digital twins in precision livestock farming (PLF)—virtual replicas of physical systems created using sensors and cameras—is presented as a method to optimize animal health, productivity, and environmental sustainability through data analytics and big data techniques.
