Comparative Evaluation of the Amino Acid Profile of the Brain and Eyesof Guinea Fowl (Numida meleagris) Hen

摘要

The amino acid composition of the brain and eyes of the matured female guinea fowl (Numida meleagris) wasdetermined on a dry weight basis. The total essential amino acids ranged from 38.4-37.5g/100 g crude protein or from47.5–52.2 % of the total amino acid. The amino acid score showed that lysine ranged from 0.81 – 0.89 (on whole hen’segg comparison), 0.92–1.00 (on provisional essential amino acid scoring pattern) and 0.869 – 0.95 (on suggested requirementof the essential amino acid of a preschool child). The predicted protein efficiency ratio was 1.82 – 2.33, the essentialamino acid index range was 1.11 – 1.45 and the calculated isoelectric point range was 4.64 – 4.32. The correlation coefficient(rxy) was positive and significant at r0.05 for the total amino acids, amino acid scores (on all the comparisons made)and the isoelectric point in the two samples. Results have good comparison with whole hen’s egg protein
