Can be. However, this invention does not provide an optimal environment for raising pigs. That is, when the pig enters the kennel, it is necessary to keep the temperature at a high temperature, but the temperature of the kennel should be gradually lowered until the moment of shipment according to the stocking age, but the above invention does not provide such temperature control.

In order to solve such a problem, a livestock artificial control device (Korean Patent Publication No. 2003-12124) has been proposed.
