Preference thresholds for taste discrimination in goats

Abstract

1. The technique for assessing rejection and acceptance thresholds for gustatory sense in goats is described.2. Quinine dihydrochloride is rejected at a level of 125 mg./100 ml. and accepted at 12·5 mg./100 ml.3. Sodium chloride has a rejected threshold of 5·0 g./100 ml. and an acceptance threshold of 1·25 g./100 ml.4. Acetic acid is rejected at 5 ml/100 ml. but is accepted at 1·25 ml./100 ml.5. Glucose does not provide data for the assessment of thresholds, since all the goats consume solutions containing the highest concentration of glucose offered, viz. 40 g./100 ml.
