【 摘 要 】

Fatty acids omega--3 and omega--6 composition and specially DHA were determined in freeze-dried chicken embryo eggs with pre-determined incubation periods. Fertile and embryo eggs presented palmitic (23.18 + 0.54%), stearic (7.70 + 0.28%), palmitoleic (3.00 + 0.19%), oleic (36.28 + 0.58%), linoleic (22.18 + 0.34%), linolenic (1.08 + 0.04%), arachidonic (2.04 + 0.03%), docosahexaenoic (0.91 + 0.03%), total omega-3 acids (2.26 + 0.10%) and total omega-6 acids (24.62 + 0.33%). There were no significant differences in total contents of omega-3 fatty acids (p=0.1226) between freeze-dried chicken embryo eggs with different incubation periods (3, 5, 7, 9, and 11 days) and fertile freeze-dried chicken eggs (day 0). However, there were significant differences in total medium contents of omega-6 fatty acids (p=0.0001). There was also a strong statistical evidence that quadratic model was related with expected values of DHA content (p= 0.0013).
