|
Gopherus agassizii Testudinidae Captive-bred juvenile desert tortoises (Gopherus agassizii) were placed in a trial arena to study feeding preferences regarding color, calcium, and insects. When presented with choices of colored food, the observed preference was green > yellow > red > orange. When presented with a choice between colored food and eggshell the observed preference was eggshell > green > yellow. When presented with a choice between colored food and cuttlebone the observed preference was cuttlebone > green > yellow. When presented with a choice between colored food and insects the observed preference was crickets > mealworms > green. These results suggest that juvenile desert tortoises may prefer some food colors over others and may consume insects opportunistically. This information may prove valuable for future captive breeding programs and for selecting an inoculation medium for disease vaccination.
