Abstract :The effect of AFB1 in feed on the liver and serum vitamin A and b-carotene levels and the ability of the liver to stor vitamin A in broiler chicks were investigated. Twenty day-old Ross broiler chicks were randomly allocated into 4 groups with 5 each in the control group, group I, group II, and group III. The chicks of the control group and group I were fed ad libitum on broiler chick growing feed. The chicks of group II and group III were fed ad libitum on feed with AFB1 insert ignore into journalissuearticles values(4 ppm/kg); feed. On the seventh day, vitamin A palmitate was administered subcutaneously at 500,000 IU to the chicks of group I and III. The experiment was continued for 21 days. On the twenty-first day, blood and liver samples were collected from the chicks. Serum and liver b-carotene and retinol levels were analysed spectrophotometrically using n-hexane extraction. The significant differences between the values obtained from the analyses were determined using Kruskal Wallis variance analysis. The differences between the groups were analysed using Duncan`s test. Serum b-carotene levels in the control group, group I, II and III were 230 ± 22.1 µg/dl, 169.7 ± 15.1 µg/dl, 124.7 ± 55.7 µg/dl, and 107.5 ± 62.0 µg/dl respectively. There were significant differences in the serum b-carotene levels between the groups insert ignore into journalissuearticles values(p
