The paper investigates the influence of dietary replacement of 3% sunflower oil (SO group) with 3% milk thistle oil (MTO group) in broiler diets on fattening characteristics and carcass quality. During 42 days of fattening, MTO group achieved insignificantly higher live weight(2.21 kg: 2.19 kg; P>0.05), significantly better feed conversion (1.80 kg: 1.83 kg; P = 0.034) and production number (292.33:285.33; P = 0.013) compared to the SO broiler group. Carcass weight and portion of main parts did not statistically significantly differ between the groups (P>0.05). Market value of carcass cuts and breast fillets was higher in MTO group than in SO group. Lipids of breast and thigh muscles in the SO group contained significantly higher concent.
