Abstract. The aim of the study was to determine whether a diet with an addition of black cumin seeds (BCS) can be used in functional egg production. At 8 weeks of age, a flock of 96 female quails was divided into 3 groups. The control group received their standard feed (0 BCS). The diet offered to the test groups was supplemented with BCS in the amount of 20 and 50 g · kg–1, respectively. Dietary BCS supplementation decreased feed intake and improved feed efficiency. Egg yolk of the quail groups treated with BCS in their diet had by a lower percentage of SFA and an increased level of UFA. A significantly increase was observed in the level of PUFA, especially in PUFA n-6. The health-promoting properties of the product were indicated by the fact of a considerable reduction in the yolk cholesterol level. Unfortunately, n-6/n-3 ratio increased in the groups offered the BCS-supplemented diet and under these circumstances eggs obtained from quails receiving BCS in the diet did not meet the requirements of functional food.
