Abstract
Rabbit meat is considered as a healthy meat compared to other kinds of meat due to the low content of fat and high content of protein. The first objective of this study was to investigate the profile of 17 amino acids in 3 different breeds of male rabbits including the New Zealand White, California and Balady rabbits from local markets in Egypt. Lysine was the dominant essential amino acid in all tested rabbit breeds. Balady breed had significantly (P< 0.05) the highest concentration of lysine (13.57 ± 1.07 g /100 g protein), and decreased successively in New Zealand White breed and California rabbits 12.24 ± 0.56 g and 9.84 ± 0.18 g/ 100 g protein, respectively. Isoleucine came second as a dominant essential amino acid in the tested samples. Same to lysine breed had significantly (P< 0.05) the highest concentration of isoleucine was found in Balady breed (8.86 ± 0.90 g/ 100 g protein), and decreased successively in New Zealand White breed and California rabbits (8.06 ± 0.28 g and 4.77 ± 0.11 g /100 g protein), respectively. Unlikely, the highest concentration of leucine was found in California rabbits (8.19 ± 0.27 g /100 g protein), and decreased successively in Balady and New Zealand White breeds (1.78 ± 0.12 g and 1.62 ± 0.06 g /100 g protein), respectively. There was a clear differences among the examined breeds and the highest concentration of essential amino acids in the New Zealand White.
