AFLATOXICOSIS IN BROILERS IN KHARTOUM STATE

Abstract

The occurrence and concentration of aflatoxins in broilers feedstuff and
livers were investigated and their toxicopathological changes in the liver
were described.
100 samples of feed including (Finished Total ration, groundnut cake and
dura (sorghum)) and 100 liver samples were collected randomly from 10
poultry (broiler) farms in Khartoum state. After extraction, the aflatoxins
were detected using ELISA test.
Aflatoxins were detected in all feedstuff samples collected .The
concentrations in total finished ration samples (60) varied between 10 and
97 ppb with a mean of 45.5 ppb, groundnut cake samples (20) ranged
between 84 and 109 ppb with a mean of 91.4 ppb and in dura (sorghum)
samples (20) varied between 7 and 10 ppb with a mean of 9.3 ppb.
Seventeen out of one hundred liver samples examined were positive for
aflatoxins residues and the concentrations varied between 2 and 12 ppb
with a mean of 4.9 ppb.
The affected liver showed hepatomegaly, paleness, wide areas of
hemorrhages and necrosis. Histopathology revealed congestion of central
vein, hemorrhages, vacuolar degeneration, necrosis and nodular lymphoid
infiltration.
