Özet

This study investigated the effects of the addition of different antioxidants to broiler diets on their live performance, liver antioxidant composition and concentrations, immune response, and meat and skin color. A total of 945 three-day-old Ross 308 broiler chicks of both genders were randomly allocated to one of nine dietary treatments (n=105), with three replicates 35 chicks per pen, as follows: T1: control (commercially available corn-and soybean-based broiler diet); T2: selenium (control+0.5 mg/kg Sel-PlexTMSe yeast); T3: vitamin E (control+200 mg/kg Kavimix-E-50 a-tocopherol acetate); T4: lutein (control+100 mg/kg 5% Lutein Beads XB); T5: lycopene (control+100 mg/kg 5% Lyco Beads XB); T6: canthaxanthin (control+25 mg/kg 10% Carophyll (R) Red); T7: apoester (control+25 mg/kg 10% Carophyll (R) Yellow); T8: lutein+zeaxanthin (control+25 mg/kg Xamacol (R)); and T9: beta-carotene (control+100 mg/kg 10% Rovimix (R)). Feed (starter, grower, developer and finisher phases) and water were provided ad libitum for 42 days. Body weights, feed intake, feed conversion values and plasma carotene concentrations were recorded weekly, and liver antioxidant concentrations were recorded at the end of the experiment. Newcastle disease (LaSota) vaccination was performed on day 22. HI titers were measured on days 14, 21, 35 and 42 to determine the effects of the antioxidants on the immune system.
