Sow precision feeding system, model and optimization algorithm

The sow feeding system has gradually become one of the important means to achieve precision feeding, improve sow production performance, and to reduce labor and feed costs. This paper systematically introduced the existing mainstream sow feeding equipment and systems, and feeding models. The linear programming method based on feed ratio, the target programming method, the genetic algorithm and the ant colony algorithm, as well as the expert system based on feed quantity and the machine learning algorithm of precision feeding model optimization were systematically reviewed, in order to provide theoretical reference for the improvement and optimization of sow precise feeding system.
