Oil Extracted Moringa peregrina Seed Cake as a Feed Ingredient in Poultry: A Chemical Composition and Nutritional Value Study

Simple Summary This research evaluates the nutritional values, protein quality, amino acid utilization, and metabolizable energy of oil-extracted Moringa peregrina seed meal as a new protein resource for poultry nutrition. The results reveal that oil-extracted Moringa peregrina seed meal is a good source of nutrients and antioxidants and has 131.4 mg/100 g dry-weight tannic acids. The oil-extracted Moringa peregrina seed meal has a considerable amount of neutral detergent fiber, acid detergent fiber, and hemicellulose. Most of the total fatty acids were unsaturated, amounting to 84.57%. In conclusion, oil-extracted Moringa peregrina seed meal has a considerable level of bioactive materials, amino acids, fatty acids, minerals, and metabolizable energy. Nonetheless, its protein quality was lower than soybean meal protein, which suggested further research. The chemical composition, antioxidant activity, tannic acid content, mineral, fatty acid, and amino acid profiles of oil-extracted Moringa peregrina seed meal (OEMPSM) were determined. Apparent (AME) and true (AMEn) metabolizable energy and apparent (AAAU) and true (TAAU) amino acid utilization were evaluated using a precision feeding trial. The protein (CP) quality was evaluated by a total efficiency analysis method. The antioxidant activity, gauged by 2,2-diphenyl-1-picrylhydrazyl (DPPH), was 237, 353, and 15.2 mg/mL for the water and ethanol extracts, and ascorbic acid, respectively. Tannic acids were 131.4 mg/100 g dry weight. The OEMPSM had 27.2% CP and 22.4, 15.1, and 15.8 MJ/kg of gross energy, AME and AMEn, respectively. The neutral detergent fiber, acid detergent fiber, and hemicellulose were 40.2, 29.7, and 10.5% DM, respectively. The 15.41% of total fatty acids were saturated and 84.57% unsaturated. The AAAU and TAAU of OEMPSM were 30.92% and 61.06%, respectively. From findings, OEMPSM comprises a valuable level of bioactive substances, amino acids, fatty acids, minerals, and energy; it can provide up to 1.12% of the requirements of total amino acids of chickens (1-21 days); however, the quality of its protein was found to be 44.6% less than that of protein of soybean meal.
