Turkey-hen amino acid composition of brain and eyes

The amino acids composition of the brain and eyes of the mature turkey-hen {meleagris gallopavo l.),were determined on dry weight basis. total essential amino acids ranged from 35.1-36.0 g/100 g as 49.5-49.8% of the total amino acids. the amino acid score showed that lysine ranged from 0.76-0.91 (on whole hen's egg comparison),0.85-1.03 (on provisional essential amino acid scoring pattern),and 0.81-0.98 (on suggested requirement of the essential amino acid of a preschool child). the predicted protein efficiency ratio was 1.94-2.41,whilst essential amino acid index range was 1.06-1.08 and the calculated isoelectric point range was 3.97-4.18. the correlation coefficient (rxy) was positively high and significant at r = 0.01 for the total amino acids,amino acid scores (on the whole hen's egg comparisons made) and the isoelectric point. on the whole,the eyes were better in 12/18 or 66.7% parameters of the amino acids than the brain of turkey-hen.
