Food preferences
With 46 out of the 66 binary combinations the lemurs displayed a significant preference for one of the two options. Apple was significantly preferred over all other food items. Sweet potato, melon, beetroot, carrot and egg were also significantly preferred over several other items. Eggplant, pumpkin, cabbage, cucumber, tomato and meal worm were never preferred over any other food item.
Food preference rankings
This table summarizes the choices made by the lemurs according to two criterions I used tto categorize the points I gave all foods during the choice process. Here we can see that apple was clearly the most attractive among the 12 food items, followed by sweet potato and melon. In contrast, meal worm, cabbage, tomato and cucumber were clearly the least attractive food items.
All four lemurs displayed similar rankings of preference for the 12 food items as their rankings all significantly correlated with each other (Spearman rs ≥ 0.62, P<0.05).
Food preference rankings and nutritional content
The food preference rankings displayed by the lemurs were highly significantly correlated with the content of carbohydrates and sucrose (Spearman, p<0.01). This was true both when the four lemurs were considered separately and when they were considered as a group. The food preference rankings did not correlate significantly with any other macro- or micronutrients.
