Biochemical characterization of solid-state fermented cassava roots (Manihot esculenta Crantz) and its application in broiler feed formulation

DATA AVAILABILTY : The availability of experimental data would be subject to reasonable request.The biochemical parameters of solid-state fermented peeled and unpeeled cassava roots (Manihot esculenta Crantz) and their application in broiler feed formulations were investigated. Fermentation occurred at room temperature for 72 h (pH 3—9). The samples utilized for five (5) broiler starter feeds were labeled: control, unfermented unpeeled cassava (UUC), unfermented peeled cassava (UPC), fermented unpeeled cassava (FUC), and fermented peeled cassava (FPC). Formulations were made by substituting fermented/non-fermented cassava roots at pH 7 for maize (w/w%). Fermentation-induced changes included increased soluble and total protein concentrations (69.3 and 334.5 mg/g) and (9.6 and 10.8%), respectively, in cultures prepared with peeled and unpeeled cassava at pH 7 compared to the control (p  0.05) for birds fed with fermented peeled and unpeeled cassava. Conversely, serum albumin and calcium levels were significantly lower (p < 0.05) for birds fed with the control feed compared to birds fed with fermented feeds. The results imply that fermented peeled and unpeeled cassava roots could be a safe and nutritionally beneficial replacement for maize in broiler diet.https://link.springer.com/journal/112742023-12-29hj2023Consumer ScienceFood Scienc
