Abstract

Olfactory bulbectomy abolished the avoidance of certain artificially flavored diets fed to rats. However, olfactory bulbectomized animals markedly curtailed their food intake as did the intact controls when fed the amino acid imbalanced or deficient diet (threonine or isoleucine limited or missing) but not the corrected diet (threonine or isoleucine supplemented). Both bulbectomized and intact animals also reduced their food intake of a high protein (75% casein) diet. Bulbectomized rats, as did the intact animals, selected a protein-free diet over the imbalanced or deficient diet but chose the basal or the corrected diet over the protein-free diet. An intact olfactory bulb is thus not essential in the control of feeding in rats fed diets involving amino acid imbalance or deficiency or protein in excess.
