Apparent nutrient digestibility of carbohydrate (corn) in Cirrhinus mrigala under the influence of chromium chloride hexahydrate

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 Cirrhinus mrigala fingerlings for 90 days. Using various levels of chromium chloride hexahydrate six test diets designated as T1 (G/0.0 Cr2Cl3.6H2O mg Kg-1), T2 (NG/0.0 Cr2Cl3.6H2O mg Kg-1), T3 (G/0.2 Cr2Cl3.6H2O mg Kg-1), T4 (NG/0.2 Cr2Cl3.6H2O mg Kg-1), T5 (G/0.4 Cr2Cl3.6H2O mg Kg-1) and T6 (NG/0.4 Cr2Cl3.6H2O mg Kg-1) were prepared. Results showed highest apparent digestibility coefficient (ADC) of nutrients dry 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 T3 test diet (G/0.2 Cr2Cl3.6H2O mg/Kg). It was concluded that chromium supplementation with gelatinized corn in fish (Cirrhinus mrigala) diet can improve the nutrients digestibility more efficiently.

Chromium supplemented carbohydrate diets for Cirrhinus mrigala: effects on body composition, gut enzyme activity and hematological parameters

“…For growth and survival of fish species nutrition is most important. To reduce feed cost carbohydrates are utilized in fish feed formulation because carbohydrates are most economical, low cost than lipids and protein and a rich source of energy (Asad et al, 2020). Factors that affect the carbohydrate utilization efficiency in dietary regimes of cultured fish species are carbohydrate origin, dietary carbohydrate content in the diets, physical state, and molecular complexity.…”
