In order to measure the edible value and to discuss the influence on the different keeping ways for chicken quality, Analysis was conducted to measure the chickens on the same species of different genders and varieties respectively. fatty acids composition were determined in the muscles of Shanbei black-bone silky fowl and Ordinary Chicken which were bred under the same feeding and keeping conditions in order to provide a basis of the study of Shanbei black-bone silky fowl function of nutrition.The results showed that: (1)the comparison of the fatty acid composition of two types of chicken fat analysis used Gas chromatography. analysis of variance showed: the content of saturated fatty acid(SAF)and unsaturated fatty acid(UFA)in Shanbei black-bone silky fowl compared with Ordinary Chicken for 0.01<P<0.05,0.01<P<0.05, respectively, the difference was significant ; the content of polyunsaturated fatty acid(PUFA)and essential fatty acid(EFA)in Shanbei black-bone silky fowl compared with Ordinary Chicken for P<0.01,P<0.01,respectively, the difference was very significant; the comparison of different sex of Shanbei black-bone silky fowl is P>0.05,not significant; the difference was very significant; the comparison of different sex of Ordinary Chicken is P>0.05。(2)the differences of tenderness was obvious(P=4.89<0.01) ,and it can be responded from the water holding capacity that Shanbei silky fowls were worse than ordinary chickens and the difference was significan(tP=0.00674<0.01). The difference may be mainly due to the feeding environment, Shanbei silky fowls always live outside but ordinary chickens inside, so the more exercise the thicker their muscle fiber. Thus we can find clearly their microscopic differences of the meat texture, and the reason for the difference of taste, which Lay the theoretical foundation for the regional chickens.
