MICROCLIMATE IN BUILDINGS FOR REPLACEMENT PIGS AND SOWS OF MEAT PRODUCTIVITY

Abstract

New temperature and humidity conditions were studied when growing replacement yong animals and management of sows of meat productivity. It has been determined that perfect temperature mode for meat productivity replacement young animals is 20-24 °C, which contributes to increase in the number of replacement gilts in estrus by 8 %, and their performance - by 3%. Sows of meat productivity are more comfortable at temperature of 17-23 °C: they showed better estrus by 4 % compared to animals managed at temperature of 13-19 °C.
