Abstract:

Present research work was conducted to assess the effects of phytase supplementation on minerals digestibility in Cirrhinus mrigala  fingerlings fed on sunflower meal based diets supplemented with graded levels (0, 500, 1000, 1500 and 2000 FTU kg-1 ) of phytase. Six experimental diets were used including reference diet and five test diets. Reference diet was fed to the fingerlings to provide appropriate nutrients for normal growth.  Test diets were consisted of 70% reference diet and 30% test ingredient i.e. sunflower meal. Chromic oxide was added in the feed at 1% concentration as indigestible marker for determination of minerals digestibility. Highest digestibility values (%) of P, Mg, Na, K, Cu and Zn were observed at 1000 FTU kg-1 level of phytase supplementation and these values differed significantly (p<0.05) from the reference diet and other test diets. Hence, it is concluded that phytase supplementation in sunflower meal based diets at 1000 FTU kg-1 level is enough to release sufficient chelated minerals to improve overall performance of Cirrhinus mrigala fingerlings.
