Forty, one-day-old male broiler chicks (Ross 308), were randomly distributed at one day of age to 2 experimental groups consisting of 10 birds with two replicates for 35 days.

Group 1 fed control diet with no Aflatoxin (AF) (negative control),while group 2 fed AF contaminated diet at a rate of 2.5ppm.

Scarifying birds done at the end of the experiment, bursa of Fabricius, liver and kidney were sectioned for microscopical examination .It was shown that AF affected Liver, kidney and the immune system organ (bursa of Fabricius), which are considered to be the target organs for AF and these are primarily affected in aflatoxicosis.
