The score of hepatic histopathology is presented in
Table 5, and the corresponding pictures from which
hepatic scores were based are shown in Figure 1.
The liver cells of birds fed control diets and diets of
36 mg FG/kg showed small amounts of lipid droplets in
the cytoplasm of hepatocytes, and all the liver samples
had a normal histological structure at 21, 28, and
35 d; thus, the total score was 0. The total scores for
ducks fed a diet of 153 mg FG/kg on days 21, 28, and 35
were the highest; ducks fed a 111 mg FG/kg diet were
intermedium, followed by the scores of ducks fed diets
of 75 mg FG/kg. The length of gossypol intake had no
clear effects on total scores of hepatic histopathology
among ducks fed diets of 75 mg FG/kg, 111 mg FG/kg,
and 153 mg FG/kg.
