Abstract: In order to realize the scientific feeding of calves and to improve the economic benefits， a calf automatic feeding control system was designed. Taking PC as management platform， this system was based on cow information management technology and wireless communication technology， an 8\|bit CMOS microcontroller STC89C52， temperature sensor DS1820， and MPX2100 type pressure sensor as the core hardware. It solved the scientific control problem of feeding temperature and the amount of milk， and realized the process from cow identification to precise feeding.

Key words: calf, automatic feeding control system, individual identification, weighing system, temperature control system
