Summary
This study optimized a taste preference test for small macaque monkey groups. Cynomolgus monkeys accept sweet and salty tastes but uniquely tolerate moderate hydrochloric acid.
Area of Science:
- Primate behavior
- Sensory science
- Animal taste perception
Background:
- Limited research exists on nonhuman primate taste preferences due to logistical challenges.
- Previous studies often required large animal groups, increasing costs and complexity.
- Developing efficient methods for taste testing is crucial for understanding primate gustation.
Purpose of the Study:
- To adapt the single-bottle preference test for small groups of macaque monkeys.
- To establish optimal parameters for a reliable primate taste preference assay.
- To investigate the gustatory responses of cynomolgus monkeys to basic taste stimuli.
Main Methods:
- A modified single-bottle preference test was developed and validated.
- Experiment 1 focused on optimizing water deprivation, test, and rehydration periods.
- Experiment 2 assessed intake of sucrose, saline, quinine hydrochloride, and hydrochloric acid solutions.
Main Results:
- Cynomolgus monkeys demonstrated acceptance of sucrose and saline solutions.
- Consistent with other species, they rejected quinine hydrochloride.
- Notably, these monkeys did not exhibit aversion to moderate concentrations of hydrochloric acid.
Conclusions:
- The adapted single-bottle preference test is effective for small macaque groups.
- Cynomolgus monkeys exhibit distinct taste acceptance profiles, particularly regarding acids.
- This research provides valuable insights into primate gustatory perception and methodology.
