Digestive efficiency and food selection under experimental conditions in the White Stork

Zbigniew Kwieciński

Abstract

Digestive efficiency in the White Stork was studied in the Poznań Zoo in 2004–2005. Altogether 29 individuals of this species were investigated (9 males, 20 females). During 10-day-long experimental cycles, the birds were presented with food according to the ‘Cafeteria’ test. The diet consisted of mammals, birds, fishes, amphibians, insects and earthworms. The mean daily food intake per bird was 284.88 g (SD 113.99 g). The mean digestive efficiency was 72.06% (SD 6.19%). The research showed that the digestive efficiency is positively correlated with the quantity of food intake and body weight increase. The daily dietary requirement of captive birds proved to be very significantly lower than in wild birds.
