Fruits

Additional advice

Divide the “Feed quantity per day” over at least three feeding moments per day.
Although present in their natural diet, feeding fruits might lead to abnormal fermentation in the hindgut because of high sugar levels in cultivated fruits compared to wild fruits (read more about nutritional values of (wild) fruits and vegetables).
Supplement a diverse selection of vegetables (read more about differences between vegetables).
Provide less palatable food in the morning, when hunger is greatest.
Feeding in bowls is not recommended.
Stimulate foraging behaviour by hiding, stacking or hanging the feed. Examples can be feeding puzzles, tubes, hanging boxes and/ or scatter feeding (read more about feed enrichment and foraging behaviour).
