What is the effect of the temperature of the delivery room on the feed intake of lactating sows?
Maintaining a temperature of about 18-20 °C in the delivery room is beneficial to the sow's feeding. Over 18 °C, for every 1 °C increase, the feed intake per sow per day will be reduced by 100 grams. It is estimated that an additional 1 kg of feed per day in the lactation period of the sow can reduce the weight loss by 7 kg throughout the lactation period. The temperature in the delivery room is lower, the sow consumes more feed, the weight loss is small, and the weaned pig has a larger body weight. Therefore, if the sow is to consume more feed, the sow should be placed in a cooler environment.
