Abstract. A study was performed to examine the outcome of utilizing hempseed, ginger, and turmeric in the diet of Hy-Line White Leghorn on the fatty acid profile of egg yolk. Four experimental rations were offered to 60 laying hens: control (standard diet); 25 % hempseed (T1); 25 % hempseed and 2 % turmeric (T2); 25 % hempseed and 2 % ginger (T3). Thirty eggs per group were analysed on day 0, 15, and 30 after storage at room temperature. Individual and total fatty acids decreased significantly (P < 0.05) in the experimental groups by day 0, 15, and 30 compared to the control. By day 0, 15, and 30, total monounsaturated fatty acids, palmitoleic acid, and oleic acid decreased significantly (P < 0.05) in T3. In fresh eggs, polyunsaturated fatty acids (PUFAs) increased significantly in T2 and T3 and were lower in the control and T1 by day 15 and 30. The same trend was also found in linoleic, eicosadienoic, and arachidonic acid. Linolenic acid increased significantly (P < 0.05) in T2 and T3 by day 15 and 30. However, eicosatrienoic acid, eicosapentaenoic acid, and docosahexaenoic acid increased significantly (P < 0.05) in all treated groups compared to the control by day 15 and 30. By day 15 and 30, total ω-3 increased significantly in treated groups. In contrast to ω-3, ω-6 increased significantly in T2 and T3 by day 15 and 30, while their ratio decreased significantly in treated groups. From the results of the present study, it was concluded that the addition of hempseed at the level of 25 % combined with 2 % turmeric and ginger in the diet of Hy-Line White Leghorn layers improved the fatty acid profile of n-3 PUFA, ω-3, and ω-6 in egg yolk.
