Abstract—Dynamic model for determining technological and economic parameters for precision pigs farming is proposed in the paper. The model includes equations describing the temperature-humidity processes, growth, feed consumption and heating in the building, depending on the controlling inputs and the measurable disturbances movements on the building's microclimate. A cost-effective temperature is determined to maximize growth and minimize feed and energy consumption by using the Direct Search optimization procedure in Matlab. A cost effective temperature for 9 climatic zones of Bulgaria in winter season for fattening pigs 45 and 90 kg has been found. The economically efficient temperature for 45 kg pigs is determined between 20,86 °C - 18,58 °C for different climatic zones of Bulgaria. For 90 kg pigs the economically efficient temperature is calculated and the results show that the temperature is the same for all climatic zones – 17.81 °C..
