Use of brooders in growing piglets to enhance their growth and preservation

Abstract

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.
