ABSTRACT

A feeding trial was carried out to assess the effect of dietary chromium supplementation on apparent nutrient digestibility coefficient (%) of gelatinized and non-gelatinized corn in Cirrhinusmrigala fingerlings for 90 days. Using various levels of chromium chloride hexahydrate six test dietsdesignated as; T1(G/0.0, CrCl3.6H2O mg Kg-1), T2(NG/0.0, CrCl3.6H2O mg Kg-1), T3(G/0.2, CrCl3.6H2O mg Kg-1), T4(NG/0.2, CrCl3.6H2O mgKg-1), T5 (G/0.4, CrCl3.6H2O mg Kg-1) and T6(NG/0.4, CrCl3.6H2O mg Kg-1) were prepared. Results showed highest apparent digestibility coefficient (ADC) of nutrientsdry matter, crude lipid and gross energy in test diet T5 that was gelatinized and supplemented with chromium 0.4 mg/Kg while, for crude protein higher value of nutrient digestibility was recorded in test diet T3(G/0.2, CrCl3.6H2O mg/Kg).It was concluded that chromium supplementation with gelatinized corn in fish (Cirrhinusmrigala) diet can improve the nutrients digestibility more efficiently as compared to non gelatinized and Cr-free diet.
