Abstract:The experienment wanted to detect the main chemical components content（moisture，protein，fat）and meat quality evaluation indexes（flesh color，muscle pH，tenderness）of chicken from different months（5 and 7 months），different sexes and different carcass parts （pectoral muscles，leg muscles）of Yunnan Boai chicken and Henan broilers.The purpose was to compare and analyze the differences in the quality of two types of chicken meat.The results showed that：（1）The muscle moisture，protein and crude fat content of Yunnan Boai chicken from different ages were similar to those of Henan broiler.The L*and b*values of muscles were significantly higher than those of Henan broiler which at the same age （P＜0.05），but the result of tenderness values were opposite（P＜0.05）.（2）There was no significant difference in moisture and protein content and pH value between Yunnan Boai chicken and Henan broiler in different sexes（P＞0.05）.The crude fat content，L*and b*values of hen of Yunnan Boai chicken were higher than hen of Henan broiler（P＜0.05）.（3）There was no significant difference in muscle moisture content and pH value between Yunnan Boai chicken and Henan broiler in different carcass parts（P＞0.05）.The protein and crude fat content，a*and b*values of the pectoral muscle and leg muscle of Yunnan Boai chicken were higher than those of Henan broiler in the same carcass parts（P＜0.05），but the result of tenderness values were opposite（P＜0.05）.
