ABSTRACT
Blood and liver carotenoids and A-vitamin and blood fatty acid modifications were observed in Eimeria tenella infested chicken. 125 chicken were alloted in 5 groups: 3 infested groups were given Amprol, Suldrazin and Clopindol respectively, in their diet. A control group was infested, a second one non-infested. Biochemical examinations were performed 10 days following treatment when chicken were slaughtered and samples collected. In control groups and in Amprol and Clopindol treated groups were seen significant decreases of liver and blood carotenoids; blood and liver A-vitamin levels were higher in Amprol treated chicken; in Suldrazin treated group no significant modifications could be shown as compared to the non-infested controls. Blood fatty acid levels were higher (43.5-47.8%) in the four infested groups and lower in the non-infested controls (39.4%). Non-saturated fatty acid levels varied within 51 and 56.4% in infested groups.
