Mineral Status of Rohu (Labeo rohita) Juveniles Fed an Acidified Phytase Pre-treated Soybean Meal Based Diet

Fish meal is the first choice for fish feed manufacturers due to its highly important protein profile. But, because of unforecasted and limited supply of fish meal, researchers are focusing to utilize plants like soybean meal in place of fish meal in fish diet. In this project soybean meal based diets were supplemented with phytase (0 and 1000 FTU/kg) and Citric acid (0 and 2%) with the purpose to enhance availability of nutrients. After the completion of trial, Labeo rohita from each replicate were taken for mineral analysis. The data was statistically analyzed by the two way analysis of variance. Acidification and phytase supplementation increased (p<0.05) the whole body minerals including Ca, Mg, Cu, Zn, Mn, Fe, P, Na and K by 10, 31, 14, 9, 19, 20, 24, 28 and 14%, respectively in the L. rohita juveniles. Which increases its nutritional value of fish in terms of minerals. © 2017 Friends Science Publishers
