Dynamic Model for Determining Technological and Economic Parameters for Precision Pigs Farmin

Belma Gaazi, Plamen Daskalov, Tsvetelina Georgieva, and Eleonora Kirilova
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..

Index Terms—Dynamic model, fattening pigs, cost-effective temperature, microclimate.
