ABSTRACT
Fifteen samples of three goat breeds; Baladi (n=5), Damascus
(n=5), and Hybrid breed (Baladi-Damascus) (n=5) were used in the
study. Amino Acid Analyzer ARACUS works according to the gold
standard of post-column derivatization with ninhydrin reagent. The
essential amino acids (EAA) Methionine, Lysine, Threonine, Leucine,
Isoleucine, Valine, Phenylalanine, Tryptophan, Cysteine, Arginine, and
Histidine were 14.1, 118.5, 99.2, 29.0, 11.6, 28.6, 130.0, 68.4, 29.8, 30.0
and 760 mmol/mol, with the total of 1319.2 mmol/mol, in Baladi goat
breed, respectively. Also, in Damascus goat breed were 12.6, 114.5, 98.6,
32.1, 10.3, 39.1, 73.5, 72.0, 27.0, 28.0 and 820 mmol/mol, with the total
of 1327.7, mmol/mol respectively. While, in Hybrid (Baladi and
Damascus) goat breed recorded of 13.1, 112, 87.0, 34.0, 9.4, 45.0, 122.0,
72.0, 26.0, 28.0 and 915 mmol/mol respectively, with the total of 1463.5
mmol/mol. On other hand, the values of Non-Essential amino acids
(Non-EAA) Alanine, Aspartate, Asparagine, Glutamine, Glutamate,
Cysteine, Tyrosine, Serine, Proline, and Glycine were 194.0, 13.9, 89.0,
340.0, 27.4, 36.0, 118.0, 240.0, 18.2 and 1320 mmol/mol respectively,
with a total of 2396.5 mmol/mol in Baladi goat breed. Also, the Non-
Essential amino acids quantitative in Damascus goat breed recorded that
180.0, 14.2, 88.0, 312.6, 21.0, 25.0, 110, 210, 16.5, and 1200 mmol/mol
with the total of 2093.8 mmol/mol respectively. Finally, in Hybrid
(Baladi and Damascus) goat breed were 230.0, 14.8, 88.0, 325.0, 21.0,
27.0, 120, 200, 13.0 and 1055 mmol/mol respectively, with the total of
2177.3 mmol/mol.
The three goat breeds revealed wide of differences between
