Fumonisin mycotoxicosis in broilers: plasma proteins and coagulation modifications.
The effects of fumonisin B1 (FB1) intoxication in chickens were evaluated in three experiments. Two-day-old broiler chicks were fed a diet containing 10 mg pure FB1/kg feed for 6 days; some chicks were necropsied at this time, and others were allowed to recover for 5 wk before necropsy. In two other experiments, 2-day-old chicks were fed a broiler starter ration prepared with Fusarium moniliforme culture material containing FB1; one group received 30 mg/kg for 2 wk, and another received 300 mg FB1/kg for 8 days. Compared with controls, intoxicated chicks exhibited decreased prothrombin time, increased plasma fibrinogen (not included for the group receiving 30 mg/kg of culture material), and increased antithrombin III activity. Simultaneously decreased serum albumin concentration and increased serum globulins could be observed in groups intoxicated with F. moniliforme culture material containing FB1. The group allowed to recover for 5 wk did not exhibit modifications in hemostasis or serum proteins compared with controls. The results indicate that low doses of pure FB1 (10 mg/kg) and FB1 from F. moniliforme culture material (30 mg/kg) may alter hemostasis and serum proteins in young chicks.
