Digestibility of feeds in fish and shellfish and methods to determine digestibility

摘要

Digestibility of a feedstuff can be described as theudamount of feed that can be digested and absorbed by theudanimal in relation to consumption. Digestibility is measuredudas digestibility coefficient when it is expressed asudpercentage and as digestible energy which is most often usedudin warm water fishes. Knowledge of nutrient availability isudnecessory for effective substitution of ingredients forudformulating low cost diets.
