Effects of Solid-State Fermentation on the Standardized Ileal Digestibility of Amino Acids and Apparent Metabolizable Energy in Peanut Meal Fed to Broiler Chickens

Peanut meal (PNM) is a byproduct of the peanut oil extraction process, but its application seriously limited by presence anti-nutritional factors, imbalance in amino acid profiles, and susceptibility to mycotoxin contamination. This study was conducted investigate effects solid-state fermentation on nutritional quality PNM, as well PNM fermented (FPNM) ileal digestibility acids apparent metabolizable energy (AME) broiler chickens. The results indicated that improved increasing crude protein, TCA-soluble L-lactic concentration (p < 0.05), decreasing fiber, phytic acid, aflatoxin B1 0.05). Solid-state also increased free level balance hydrolyzed PNM. A nitrogen-free diet used determine loss endogenous birds, or FPNM only protein source formulate semi-purified diets. result showed feeding resulted higher (AID) standardized (SID) values essential methionine, lysine, leucine, phenylalanine Moreover, AID SID non-essential were both than those except for proline AME determined classic substitution method, had no effect value > In conclusion, potential ingredient an alternative broilers.
