Abstract

The total food intake and growth efficiency of growing rats were not affected by the feeding of a mild protein restricted (10%) diet containing an aversive taste stimulus. However, growing rats fed the same diet for a period of 18 days, suffered an inhibition of growth efficiency if the taste character of the diet was changed daily by the addition of a single but different aversive stimulus. For a period of time (9 days), these changes in diet palatability did not affect the total food intake. Rats fed diets containing a combination of the aversive taste changes and commercial soybean trypsin inhibitors, suffered an additional inhibition of growth efficiency. It is postulated that these manipulations in diet palatability interfered with digestive or metabolic processes.
