The purpose of this study was to analyse the influence of different external air temperatures on changes in the air temperature of housing environment in a farrowing house for sows and consequent changes in selected indicators of performance in purebred Landrace sows and gilts. Data were analysed for 236 litters born from October 2004 to March 2006. Air temperature in the farrowing house was monitored in the sow's living zone and was closely related to changes in external air temperature (P less than 0.01). At the optimal internal temperatures for lactating sows (16-22 deg C) during mild winter the lowest incidence of stillbirths (9.92%) was detected, whereas at high internal temperatures (above 28 deg C) the incidence of stillbirths was 11.32% (P less than 0.01). The lowest average daily weight gain was recorded during mild winter (P less than 0.05).
