Male rats weighing 178 to 233 g initially were fed to appetite for 9 days on Purina Laboratory Chow; for the next 8 days food intake was limited to reduce weight to 80% of that when fed freely. The rats were then offered to drink a choice between water and 5.6% ethanol solution, 6.05% 1,3-butanediol or 5.6% acetone in normal conditions or in shock-induced polydipsia. More alcohol or butanediol than acetone was drunk, indicating that fluid intake was based on need for energy rather than for alcohol.
