The hens were distributed randomly into six treatment, each group comprises of 3 replicates with 10 layers in each replicate different levels of dietary dill (Anethum graveole (0.0, 0.20, 0.40, 0.60, 0.80 and 1.00%) were used as an additive to a basal diet. The results showed that dietary dill additives significantly improved the hen-day (H.D) % of egg production, egg mass, FCR, shell strength, yolk weight and Haugh unit. Meanwhile dill significantly increased vitamins A, D and E by 44.61 %, 14.67 % and 8.73 %, respectively. Additionally, significant increase in the ratio of folic acid and zinc by 14.01 %, and 7.04 %, were recorded respectively. Moreover, adding dillhad significantly decreased cholesterol levels in egg yolks and total lipids by 9.53% and21.90% respectively, In conclusion, supplementing layers’ dietary dillhad improved egg production ,So, such eggs can be used as functional eggs for different health conditions which exposed to cardiovascular diseases, hyperlipidemia, diabetes, etcKey Words: Cholesterol, Fat-soluble vitamins, Folic acid,ISA-Brown, Zinc.
