The aim of this study was to investigate the concentrations of Docosahexaenoic acid (DHA) in DHA enriched hen egg yolk (H-DHA) in comparison with egg yolk from chicken, duck, quail, ostrich and crocodile in order to find a source of DHA for boar semen cryopreservation. A pool (10 eggs in each) of DHA enriched hen egg yolk and egg yolks from chicken, duck, quail, ostrich and crocodile were analyzed for fatty acids profile at the Nutrition Laboratory, Mahidol University. Comparing all egg yolks, the highest DHA concentration in egg yolk was found in H-DHA egg yolk (3.7% of total fatty acid) and the lowest was found in ostrich egg yolk (0.4% of total fatty acid). Comparing DHA concentration in all egg yolks (not including H-DHA egg yolk), the highest DHA concentrations were found in duck egg yolk (1.8% of total fatty acid) and quail egg yolk (1.5% of total fatty acid), respectively. In conclusion, H-DHA, duck and quail egg yolks can be an abundant source of DHA for boar semen cryopreservation.
