Ingestive response shows absence of taste aversion after bovine satietin in rats.

Abstract

Six adult male rats (409 +/- 16 g) were equipped with chronically implanted oral catheters. Facial consummatory responses to gustatory stimuli, of 50 microliters 2.0 mol.1-1 banana or coconut flavoring, were recorded on a +4/-4 scale for 30 s. The new flavors were paired with IP injections on three different days. The rats were injected with either saline or 1 mg.kg-1 bovine serum satietin (bs-SAT). Food intake and body weight were reduced (p < 0.005) after satietin but not after saline. Both coconut and banana flavors aroused mild ingestive responses in the naive rats. Five days after the beginning of the pairing with IP injections, the rats' response to coconut and banana remained unchanged. The results show that satietin was able to reduce food intake and body weight but did not arouse taste aversion.
