Abstract: The amino acid composition and content of Black chicken, Pearl chicken （male and female）, Guifei chicken, Dabai chicken and Jute chicken were analyzed and evaluated by biochrom 30+automatic amino acid analyzer. The results showed that 17 kinds of amino acids, 18.88, 19.70, 18.80, 20.48, 18.98, 18.30 g/100 g, were detected in Black chicken, Pearl chicken （male and female）, Guifei chicken, Dabai chicken and Jute chicken. The EAA/TAA and EAA/NEAA of Black chicken were 40.89% and 69.18% respectively; that of Dabai chicken was 40.91% and 69.24% respectively; that of Guifei chicken was 41.17% and 69.98% respectively; that of pearl chicken （male） was 41.89% and 72.10% respectively; that of Pearl chicken （female） was 41.62% and 71.30% respectively; that of Jute chicken was 41.09% and 69.76% respectively. The proportion of amino acids of the five kinds of chicken was reasonable and the nutrition was comprehensive, which was the source of high-quality protein. （male and female） meat is better.
