Abstract
Currently, pig farming in the Republic of Belarus is characterized by a sharp increase in genetic productivi- ty potential, which has led to the need to improve the comfort of animal housing conditions. In this regard, the possibility of increasing air exchange in premises for keeping suckling meat-type sows was studied. The research was conducted during the cold, transitional, and warm periods of the year. The level of air exchange in the experimental group was increased during the cold period to 110 m3/h per head, during the transitional period to 150 m3/h per head, and during the warm period to 200 m3/h per head. This led to a decrease in indoor air temperature by 0.1–0.4 °C, relative humidity by 3.5–4.1 р. р., carbon dioxide content by 0.01–0.02 р. р., ammonia content by 0.2–0.7 mg/m3, an increase in oxygen content by 0.2–0.5 р. р., and an increase in air velocity by 0.04–0.1 m/s. The improvement in the microclimate contributed to an increase in the average daily weight gain of piglets during the suckling period by 3.3–4.0 % and an increase in litter weight at weaning by 2.8–6.5 %.
