ABSTRACT
Phytate, bound form of phosphorus and some other minerals, is present in plant products and it cannot be consumed by fish because there is no phytase activity in agestric fish. This study was performed to determine the impact on proximate composition of whole-body of Labeo rohita (fingerlings) fed distiller’s dried grains with solubles based diet, supplemented with phytase. Six different feeds were formulated by supplementing different concentrations of phytase. i.e. D1 without phytase supplementation, D2, D3, D4, D5 and D6 with 250, 500, 750, 1000 and 1250 FTU phytase per kilogram of diet, respectively. An experiment was conducted for 2 months. During this experiment, water quality parameters were also examined e.g pH, Dissolved oxygen and temprature. Results were examined by Tukey’s Honestly Significant Difference Test. Phytase supplementation decreased the moisture content and increased the crude ash, protein and fat significantly in proximate composition of whole-body of the fish and hence, improved the meat quality of Labeo rohita fingerlings.
