Relationship between Eimeria adenoeides infection and aflatoxicosis in turkey poults.

ABSTRACT

Three-week-old turkey poults receiving 250 micrograms/kg of dietary aflatoxin displayed prolonged prothrombin times due to decreased fibrinogen levels and depressed activity of factor II. Decreased body weights and increased mortality were also evident. Poults experiencing an Eimeria adenoeides infection had slightly increased prothrombin times that were not corrected by the addition of specific clotting factors. These birds exhibited significant reductions in total plasma protein levels. The combination of E. adenoeides and aflatoxicosis resulted in a significant depression in body weight, altered prothrombin time, and decreased levels of plasma calcium, protein, and fibrinogen. Increased mortality was also observed. E. adenoeides did not affect the hemostatic system of the turkey as severely as does aflatoxin. Turkeys were shown to be highly susceptible to aflatoxin when compared to chickens.
