Digestion and utilization of organic nutrients by growing eels

, : Digestion and utilization of organic nutrients by growing eels. Zeitschrift fuer Tierphysiologie Tierernaehrung und Futtermittelkunde 48(3): 138-143

In 8 individually kept eels, which almost doubled their initial weight of .apprx. 175 g during the trial, digestibility of nutrients of a purified diet was determined. Protein from casein/gelatin and fat from sunflower oil were digested almost completely, N-free extract from gelatinized maize starch had a digestibility of 85%. The weight gain was 42% fat and 13% protein. About 60% of the digestible energy could be recovered as energy retention.

Eels of the broad-jaw variety (Breitmaul) were selected because their growth capacity is expected to be over 200 g. The 8 eels, initially of bodyweight about 175 g, were kept singly in water of pH 7.4 at 25 deg C with oxygen 8.3 mg/litre under art...
