Natuurlijk dieet Polar Bear

Polar bear are strictly carnivorous predators. They primarily feed on seals, but occasionally larger prey such as walruses and narwhals are consumed too. Food intake increases during spring/summer months to accumulate enough fat because of hibernation during the winter period.

Aanvullend advies

  • Divide the “Feed quantity per day” over at least two feeding moments per day.
  • Polar bears have a high need for fat and a low demand for protein. This should be taken into account when selecting the diet.
  • Polar bears have different nutritional needs every season. Although fasting days are inappropriate for bears in captivity, the diet should be adapted accordingly to the activity levels to avoid obesity (read more about seasonal fluctuations and hibernation).
  • The supplements should be given according to the appropriate dosage that is mentioned on the labelling.
  • To promote the oral health, it is important to offer the soft food first and then the hard food such as bones and skin.
  • Stimulate foraging behaviour by hanging, stacking or hiding the feed. For instance by feeding large bones, frozen food or placement in food puzzles (read more about feed enrichment and foraging behaviour).
