This study was conducted to assess the effects of phytase supplementation on minerals digestibility to Labeo rohita
fingerlings that were fed corn gluten meal (30%) based diet. The experimental diet was consisted of 70% reference diet and
30% test ingredient i.e. corn gluten meal contents. The chromic oxide was included at a concentration of 1% as nondigestible marker in the feed. The results of the study showed that the high digestibility (%) of P, Mg, Na, K, Cu and Zn was
observed at 750 FTU kg-1 level phytase supplementation and differed significantly (p<0.05) from the reference and other test
diets. The present study suggests that the supplementation of feed with phytase enzyme may reduce the need for
supplementing minerals, resulting not only lower feed cost but mineral discharges through feces into the aquatic ecosystem.
