“…The effectiveness of the following four options of heating system for prenursery pigs was experimentally evaluated: electrically heated mat (EM), water-heated mat (WM), water-heated 'warm' floors (FH), and infrared heating lamps (IRL). Based on the research results, taking into account statistical data on average daily gain (ADG), mortality rate of prenursery pigs, as well as the effect of heating on their behavior, use of electrically heated mats or 'warm' floors with water heating were considered the most effective local heating system within the period of the first five weeks (starting from the third week) [22][23][24][25][26][27]. A carbon fiber heater has been developed for the local heating of breeding saw with prenursery pigs, providing the required thermal comfort and reducing power consumption compared to conventional heating lamps (HL) [28].…”

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.

A method of heat localization in the resting area of piglets is proposed. It has been established that the combined use of brooder and radiation or contact heating makes it possible to provide a temperature of 30.0 ± 0.17 … 30.4 ± 0.26 °C for the up to three-weeks-old aged young stock, and 26.6 ± 0.26 … 26.5 ± 0.27 °C without heating means for the seven-week-old aged animals, a reduction of air velocity by 40-50%. The installation of brooders for weaners at rearing allows creating a temperature of 23.4 ± 0.32 … 26.2 ± 0.28 °C, reducing its speed by 26.7…35.7% (P≤0.001) in comparison with the control. The use of brooders for heating contributes (P≤0.001) to an increase in the growth of live weight of young animals by the end of growing period by 8.6…9.6%, the livability – by 2…3%, and the improvement of hematopoiesis, in comparison with radiation heating by infrared lamps.
