ABSTRACT

A fish nutritional trial was conducted for 90 days to find the effects of inorganic chromium and organic chromium on feed digestibility and muscle composition of (Labeo rohita fish). Six treatment groups were prepared with one control group (each with two replicates), three groups supplemented with inorganic chromium chloride hexa hydrate (CrCl36H2O by 0.3, 0.5 and 0.6mg/kg) and three groups supplemented with organic chromium picolinate (Cr-Pic-0.3, 0.5 and 0.6mg/kg) were used. It was found that Labeo rohita fed on inorganic chromium (CrCl2 Hexahydrate) showed maximum digestibility coefficient for ash and dry matter nutrients. In case of body muscle composition, fish fed on organic chromium (picolinate) showed highest deposition for dry matter, crude protein and gross energy. While comparing organic and inorganic Cr efficiency in fish feed, it was concluded that organic chromium (picolinate) inclusion increased the nutrients digestibility and enhanced the nutrients deposition in body muscles of fish.
