“…Постійна селекція свиней на підвищення їхньої м'ясності, яка зумовлює зниження прошарку підшкірного жиру, також вимагає корекції задля підтримання кліматичних параметрів у приміщеннях (Povod, 2014). Питання щодо порівняння різних систем вентиляції та вивчення їх впливу на продуктивні якості лактуючих свиноматок і ріст підсисних поросят є актуальним та потребує поглибленого дослідження (Broom et al, 1995;Caldara et al, 2014;Zhelykh et al, 2017). Мета -виявлення залежності відтворювальних якостей підсисних свиноматок, інтенсивності росту їх потомства залежно від техніко-технологічних процесів створення мікроклімату в приміщенні для їхнього утримання.…”

Technological group of lactating sows with suckling piglets, are very sensitive to any climate change. They are basis for the next development and implementation of their genetic potential, therefore one of the most important issues of housing is the right choice of the microclimate creation system. One of the main tasks in this case is also the reduction of energy costs to provide proper parameters, both for animals and for their service staff. The effect of microclimate parameters created by means of traditional and geothermal ventilation systems on the performance of lactating sows and the growth of suckling piglets in the spring and autumn seasons are understood by us. The analysis of sows' performance was carried out according to the following parameters: number and weight of nest of newborn piglets, multiple birth, large-foetus fertility, number of piglets at weaning, survival rate, individual live weight and weight of the nest at this time. The analysis of the intensity of growth of piglets was studied by absolute, daily average and relative live weight gain. For a comprehensive assessment of the reproductive qualities of the breeding stock, which was held under different conditions of microclimate creation, the estimated index of the design of M. D. Berezovsky (1986) was used. According to the results of the experiment, both ventilation systems provided optimal indicators of air humidity, speed of its movement and maintained gas composition in the premises within the recommended limits. The geothermal room ventilation system allows you to create more comfortable temperature conditions for both piglets and sows, compared with the traditional ventilation system. The best microclimate conditions created by the geothermal ventilation system in the pigsty for carrying out farrowing contributed to improving the survival rate of piglets before the weaning period, the intensity of their growth, and the increase in live weight gain and nest mass at weaning both in autumn and spring. The research in this direction is planned to continue for other technological groups of pigs, and their results will be used in the design and reconstruction of pig farms.

“…Today, the independent room conditions for breeding sows and for piglets are provided by creating local heating areas with the help of heated floors, IR thermal radiators, brooders, and piglet kennels [5]. The most favorable conditions for breeding prenursery pigs can be ensured by the application of combined heating when the heat is transferred to the animals both from the bottom and from overhead with the help of infrared thermal radiation and heated floors, panels or mats [6][7][8][9]. Heating is mainly achieved by the use of either electric resistance heaters or hot water [10][11][12][13].…”

Mathematical formulation of the animal thermal status has been developed, with the account of two convenience conditions and heat balance, for the floor-mounted heating panel for prenursery pigs. The borders of the heat flux variation range for the floor-mounted heating panel have been determined corresponding to the animal-friendly conditions for prenursery pigs of various age groups. The block diagram of the energy-saving floor-mounted heating panel, comprising the thermoelectric assembly operating in the heat pump mode, has been designed. The method has been described and the corresponding calculations have been made for the basic thermal parameters of the floor-mounted local heating installation, for prenursery pigs, with the application of a thermoelectric heat pump. The experimental installation sample of 116 W thermal capacity (for the heat transfer coefficient from 0.9 W·m−2·K−1 to 1.0 W·m−2·K−1 and floor temperature in the range of 5 °C to 6 °C) has been developed and manufactured for local heating for prenursery pigs managed in gestation crates. Laboratory tests of the experimental sample of the floor-mounted heating panel have demonstrated high energy efficiency of the heating installation under development. The energy-saving effect (approx. 15% compared to the series-produced equipment designed for local heating of young stock) of the developed installation was achieved owing to the partial heat recuperation of the exhaust ventilating air.

“…Since, in the amplitude of the internal temperature fluctuation over than 15 ºC, the methane formation process is stopped, therefore, it is necessary to provide the bioreactor with the required amount of thermal energy throughout the fermentation cycle, at the same time consuming as little energy as possible ( Ulewicz, M., 2020;Zhelykh, V., 2017;European Commission. Nearly Zero-Energy Buildings.…”

Ukraine has significant land resources for agriculture and is able to provide its population not only with food but also with raw materials for bioenergy. The article presents a graph of heat capacities and the distribution of heat flows in a bioreactor. The dependences for determining the heat fluxes of flat and cylindrical surfaces are presented. The article outlines the present state of utilization of fallen leaves of trees. The method of utilization by anaerobic fermentation is proposed. The design of bioreactors and the main factors influencing the methane formation process are considered. The methodology for calculating the biogas production process is presented. The productivity of the bioreactor has been determined, depending on the temperature of the raw material and the time of hydraulic resistance
