Abstract: This study was conducted to evaluate the nutritional status of Rhizopus oryzae fermented Mangifera indica seed kernels and its effect on the growth performance of broilers. Fermentation increased the crude protein value of unfermented mango seed kernel from 4.61 to 7.06% while a decreased was observed in ash, lipid and fiber content of fermented mango seed kernel. Fermentation also increased the bioavailability of phosphorous (2.67mg/kg), potassium (2433mg/kg) and calcium (0.4mg/kg). Fermentation caused a decrease in the anti-nutritional content of unfermented mango seed kernel with an initial value of 0.02mg/g for oxalate, phytate (15.27mg/mol), Tannin [0.53mg/mol], nitrate (2.62 mg/mol), cyanide (0.80 mg/mol) to 0.01mg/g for oxalate, phytate (5.24 mg/mol), tannin (0.31mg/mol), nitrate (0.05 mg/mol) and cyanide (0.07mg/mol). Broilers fed fermented mango seed kernel plus conventional feed ration had a lower final body weight (2.2kg) compared to the fermented mango kernel based diets chicks (2.6kg) and control (2.9kg). The study shows that Rhizopus oryzae caused an improvement in the protein, mineral and antinutritional values of raw mango seeds. It also shows that replacing maize at 50% level of inclusion with Rhizopus oryzae fermented mango seed kernel in broilers rations had no adverse effect on the growth performance of broilers thereby suggesting that it could be used in poultry feed formulation especially for small scale farmers.
