Summary

1. Rates of heat loss from 12 groups of pigs were measured over 4-week periods in a large direct calorimeter equipped as a pig pen.

2. The levels of feeding in different groups were 34, 39, 45 and 52g/kg body weight per day, and the calorimeter temperatures were 7°, 12°, 20° and 30°C.

3. At 12°, 20° and 30°C the rates of heat loss were related to the level of feeding.

4. At 7°C the mean rate of heat loss was higher than at the other temperatures, and was not related to the level of feeding.
