Effects of food deprivation on water intake induced by intermittent delivery of salted liquid food

The water intake of rats maintained through food deprivation at 70, 80, 90, and 100% of free-feeding body weights was examined under conditions where a small amount of sweetened condensed milk containing 8% sodium chloride was presented at one-minute intervals. For each of two subjects, number of licks and milliliters of water consumed varied inversely with body weight. This finding agrees with earlier reports concerning the effects of food deprivation on adjunctive behaviors induced by intermittent delivery of dry food.
