The negative effects of high temperatures on performance during sow lactation have been well documented. An increase in ambient temperature leads to a decrease in feed intake which in turn decreases milk production, increases the mobilization of body reserves and delays the return to oestrus of weaned sows. Most of the studies conducted have focused on the effects of elevated temperature on feed intake and lactation; data on the changes in feeding behaviour under hot conditions are limited. The present paper reviews studies on the effects of hot conditions on feeding behaviour in lactating sows.
