The egg shell percentage was 16.7; proximate levels were (g/100 g): protein 3.34, fat 1.50, ash 8.33, soluble carbohydrate 90.0 and gross energy 1489 (kJ/100 g) and the utilisable energy due to protein was 34.1 %. Sample was high in Na, K, Ca, Mg, Zn but low in Mn, Fe, P and Ca/Mg. Many essential acids were of high concentration: Lys, His, Arg (the most concentrated acids, 52.0 mg/g), Thr, Val, Leu, Ile and Phe. Limiting amino acid score showed that Ser shared the position with Tyr (0.14) in hen’s egg composition, it was Met+Cys (0.26) in the provisional score comparison and Leu (0.31) in the comparison with pre-school child requirement. https://www.biotech-asia.org/vol6no2/chemical-composition-of-guinea-fowl-numida-meleagris-egg-shells/ Guinea fowl; egg shells; chemical composition
