The temperature at which this occurs varies from boar-to-boar but can start from around 25oC. The temperature in boar houses should therefore be monitored. If ambient house temperatures are high supplemental cooling is advised e.g. by drip-lines, misting or washing down passageways to increase evaporative cooling and introducing some airflow across the pigs.
Semen quality can be adversely affected for up to six weeks after hot weather.
