The study was conducted to investigate the effects of different designer diets on egg quality and fatty acid profile of kadaknath eggs. A total of one hundred eighty, 30 weeks age laying hens (Kadaknath birds) were selected. These layers were randomly distributed to 5 replicates having 6 birds each and were allotted to 6 dietary treatments. T₀ (basal diet), T₁ (basal diet having 10% Flaxseed replace), T₂(basal diet having 1.5% fish oil), T₃ (basal diet + Vitamin E 1000 mg/kg feed), T₄ (basal diet + multi-enzymes 2 g/kg feed) and T₅ (basal diet having 5% flaxseed, 0.75% fish oil, 500 mg Vitamin E/kg feed and 1 g multi-enzymes/kg feed). Experiment was conducted for 12 weeks period from 31^st to 42^nd weeks. Egg quality parameters and fatty acid profile of egg collected at 4 weeks intervals were determined.

The egg quality parameters like shape index, albumin index, yolk index, Haugh index and shell thickness were not affected by designer diet. PUFA content in egg yolk were significantly (p<0.05) increased in groups supplemented with 10% flaxseed, 1.5% fish oil and combination supplemented group while the MUFA and SFA content in egg yolk were decreased due to designer diets. Omega6: omega3 fatty acid ratio was also improved in T₂, T₁ and T₅ groups (1.5% fish oil, 10% flaxseed and combination supplemented groups).
