Abstract

The present research work was conducted to evaluate the role of phytase supplementation in improving nutrient digestibility in Labeo rohita fingerlings fed cottonseed meal-based diets having 30% protein and 4.15 k cal g-1 gross energy. The experimental diet comprised 70% reference diet and 30% cottonseed meal as test ingredient. The experimental diet was top sprayed with graded levels of phytase viz., 0, 250, 500, 750, 1000, 1250 and 1500 FTU kg-1 resulting in the formulation of seven test diets. Chromic oxide was used as indigestible marker in the feed to estimate nutrient digestibility. Results showed improved crude protein, crude fat and gross energy digestibility in response to phytase supplementation. Maximally improved nutrient (crude protein and crude fat) and gross energy digestibility was observed in fingerlings fed 750 FTU kg-1 phytase containing diet followed by the diet having 1000 FTU kg-1 phytase level. It was concluded that phytase supplementation to cottonseed meal-based diet at 750 FTU kg-1 level is adequate to release chelated nutrients from phytate for fish.
