Pirarucu (Arapaima gigas) is an Amazonian carnivorous fish species with great aquaculture potential. The apparent digestibility coefficients (ADC) of corn, low-tannin sorghum, broken rice, defatted rice bran, and wheat bran were determined for juvenile pirarucu using a completely randomized block design (two time blocks with two replications per block). We also evaluated the influence of digestion on the structure of starch granules by scanning electron microscopy (SEM) of the feed and faeces. The ADC of nutrients and energy, except protein, differed among plant sources. Broken rice and corn were the most digestible starch sources for dry matter (81.14 +- 8201;1.52) and energy (77.66 +-2.36) respectively. Starch digestibility was inversely related to the starch content and directly related to the fibre content of the tested ingredients. The highest and lowest starch ADC were detected for wheat bran (103.44 +- 5.41) and low-tannin sorghum (53.35 +- 5.18). Structures similar to spherulites were detected in the faecal samples of corn-fed fish, possibly owing to lower starch digestibility. Considering the energetic purpose of the tested ingredients, corn and broken rice were the most suitable energetic sources because they provided higher digestible starch and energy values. |
