Abstract

Nutritional composition and apparent digestibility coefficient of dry matter, crude protein, ether extract, gross energy, essential amino acids and no essential amino acids of spray dried whole yeast, autolyzed yeast and yeast cell wall were evaluated to Nile tilapia. Eighty juveniles (83.0±8.5g) were placed in eight 250L aquaria for feeding and four aquaria of the same volume for collecting faecal samples. Both sets were equipped with flow-trough recirculating system provided with mechanical and biological filter. The results were analyzed through comparative relative index and the 100% value corresponded to the whole yeast nutrients. It can be concluded that the whole yeast contains high protein level and good apparent digestibility to nutrients and amino acids; autolysis process improves the dry matter, crude protein, gross energy and the most of essential and no essential amino acids apparent digestibility. Moreover yeast cell wall must not be used as protein source but is suggested as functional foodstuff in Nile tilapia diets.KEY WORDS: Amino acids, Oreochromis niloticus, Saccharomyces cerevisiae
