The present study was aimed to assess the effect of black cumin (Nigella sativa) oil on egg-yolk lipid profile of adult layer birds. Twenty four 40-weeks-old Jabalpur color birds were fed on 4 dietary treatments. Birds were caged individually and diets were supplemented with 0 (control), 250, 500 and 750 mg black cumin oil/kg of feed in group T1, T2, T3 and T4 respectively for 56 days. Egg yolk lipid profile was estimated on 0, 14, 28, 42 and 56th day of feeding. The variation in egg-yolk total lipids, cholesterol and triglycerides between intervals within treatment were highly significant (P< 0.01). The study revealed that supplementation of black cumin oil @ 750 mg kg-1 feed is most effective in reducing the egg yolk lipid profile in Jabalpur color birds fed for a period of 56 days.
