Abstract: The objective of this study was to assess the meat nutritional components between Jingyuan chickens with varied feather colors (white, linen and black) and to evaluate their differences. The core group of the fifth generation of the Jingyuan chickens with three different feather colors were used as experimental animals. The contents of initial moisture, fat, protein and amino acid of the chest muscles and leg muscles were determined by using direct drying method, Soxhlet extraction method, micro -Kjeldahl method and amino acid determination method recommended by national standard GB 5009.124 -2016. The results showed that the initial moisture content of the chest muscles and leg muscles of the three groups of Jingyuan chickens with different feather colors was 71.10%, 70.35%, 70.69% and 72.14%, 70.13%, 72.08%, respectively, and no significances were observed (P>0.05). The highest fat content in the chest muscles and leg muscles was observed in the black-feathered Jingyuan chickens, which was 2.19% and 3.12%, and the lowest was observed in the white-feathered ones. The highest protein content (24.30%) in the chest muscles was observed in the linen-feathered Jingyuan chickens, followed by the white-feathered ones and black-feathered ones. No significant difference in protein content of the leg muscles was found between the three groups (P> 0.05). There was no significant difference in meat amino acid content between the three groups (P >0.05). The content of glutamate in the chest muscles and leg muscles was the highest, followed by aspartic acid, lysine, leucine and arginine. The linen -feathered Jingyuan chickens had the highest contents of essential amino acid and total amino acid in chest muscles compared to the other two groups. While the highest content of essential amino acid in leg muscles was observed in the linen-feathered Jingyuan chickens, the highest content of total amino acid was found in the white-feathered ones. Our results may have referential value for consumers when purchasing Jingyuan chicken.
