Description: The frequency, duration and intensity of heat waves have been increasing for the last decades leading to heat stress episodes in livestock production. Ventilation systems and cooling techniques are common ways to manage ambient air and heat stress in pig production. This study aims to evaluate the effect of the integration of the Housed Swine Heat Stress Index (HS2I) in a new ventilation control strategy. The HS2I animal comfort ventilation strategy was compared to a common temperature setpoint ventilation strategy on an experimental scale. Two rooms of an experimental farm were used to compare the performance of both strategies on pig performance. Fourteen pigs per room were raised from 45 kg to 115 kg for ten weeks. The initial temperature setpoint was 22?C and artificially increased some weeks up to 30?C to create heat episodes/heat waves. Each ventilation strategy including an extraction and a recirculation fans and a water sprinkling system. The breeding performance; water and feed consumption; pig skin temperature was evaluated to compare both strategies. Results suggested that the new strategy enabled keeping the comfort of the pigs relatively constant according to the HS2I target value. These results show the possibility to improve ventilation control strategies in pig production buildings by measuring and incorporating several variables that influence the performance and comfort of the animals.
