According to an embodiment of the present invention, the pigeon environment management system is divided into n sections, and a database in which a control table and an internal temperature including an appropriate weight and an appropriate temperature range are stored； A weight sensor capable of transmitting the initial weight data measured at a predetermined time point of the pigs inside the piglet and the target weight data measured at a time point when the first target time has elapsed from the time point； A heating module installed inside the donsa to provide a heat source； A cooling module installed inside the pig house to provide a cold source； An internal temperature sensor installed inside the pig house to measure and transmit the inside temperature (Ti) of the pig house at a predetermined time interval； And an average weight calculation unit that is electrically connected to the database, the weight sensor, the heating module, the cooling module and the temperature sensor, and calculates the average weight of the pigs by using the initial weight data transmitted from the weight sensor. And, an appropriate temperature search unit for searching the appropriate temperature range (Ta ~ Tb) corresponding to the k section of the appropriate weight to which the average weight belongs in the control table, and the internal temperature (Ti) transmitted from the internal temperature sensor And a driving unit controller for driving the cooling module of the piglet when the internal temperature (Ti) is higher than the Tb and driving the heating module of the piglet if the internal temperature (Ti) is lower than the Tb, at a preset first target time. When it reaches, the average temperature calculation unit calculates an average temperature (Tm), which is the average value of the internal temperatures stored in the database, and recalculates the average weight using the target weight data received from the weight sensor and calculates the average weight It may include；
