• Under tropical conditions, climatic factors, impact negatively on the performance and voluntary feed intake of lactating sows.
• Lactating sows modify their kinetics of feed intake and feeding pattern during the hot season to reduce the effects of high ambient temperatures.
• Change in kinetics of feed intake and feeding pattern impacts on their daily milk production and consequently on litter performance.
• Feed flavours offer the potential to change kinetics of feed intake and feeding pattern and increase sow lactation feed intake and as a consequence improve milk production and litter weight gain.
