Improvement in overall performance of Catla catla fingerlings fed phytase included low cost plant by products-based diet

摘要

Phytic acid’s presence in low-cost Moringa by-products effect the availability of important nutrients, diminishing the fish quality and blood composition in fish. Phytate having chelating effects with nutrients and minerals, can be reduced by the supplementation of phytase enzyme. Without the use of enzyme, plant meal may cause water pollution and decrease the fish health that results in higher culture cost. Therefore, current study was designed to check improvement in overall performance of fingerlings fed Moringa by product-based diets supplemented with phytase (0, 300, 600, 900, 1200 and 1500, FTU/kg). All diets were integrated with non-digestible marker (Cr O ) at the rate of 1%. The fingerlings were fed couple of times a day (4% of live wet weight). Results showed significant (
