The study determined the effect of the addition of 15% of camelina, flax, and sunflower seeds to iso-caloric and iso-nitrogenous diets for broiler chickens during 21&ndash:42 days of age on the nutrient digestibility, production traits, slaughter analysis parameters, hematological indices, blood mineral elements, and dietary value of breast and drumstick meat. Two hundred one-day-old broiler chickens were assigned to four groups (treatments) with five replicates (10 birds per cage, 5 females and 5 males). The experiment lasted 6 weeks. Broiler chickens receiving diets supplemented with camelina and flax seeds exhibited an increase (p <: 0.05) in average body weight and a decrease (p <: 0.05) in the ether extract content and energy digestibility of the diets. Moreover, the best carcass quality with a high proportion of muscles and low abdominal fat content (p <: 0.05) was noted in broilers fed flax- and sunflower-enriched diets. The treatments with the oil seeds reduced the ether extract content and the calorific value of breast and drumstick muscles. The flax seeds contributed to an increase in the Fe content in drumstick muscles. Additionally, some blood parameters were influenced by the flax seed supplementation, e.g., the level of hemoglobin declined (p <: 0.05) and the iron level in plasma increased (p <: 0.05). It can be concluded that the camelina, flax, and sunflower seeds can be regarded as good dietary components with positive effects on the dietary value of poultry meat.
