To solve a problem such that the judgement and control of physical conditions of cattle become large burdens by the decease of labor population, increase of highly aged workers and increase of breeding number in diary farms.

This cattle control system is composed of cattle instruments for sensing multiple number of information regarding to the cattle and a host capable of communicating with the cattle instruments, and the method for controlling the cattle is provided. By the cattle instruments, the sensed data are compared with threshold data specific to the kind of sensing, and evaluated again based on the data changing with time, when there is any possibility of an abnormality. By the host, proper countermeasures are devised based on the data and information from the cattle instruments.
