Chickens fed charcoal-
supplemented diets consumed on average around 2%
less feed per kilogram of body weight than control group
birds.
The mortality rate of birds was similar in both groups,
reaching 3.7% in the control group and 3.1% in the experimental
group. The addition of charcoal to diets had no
significant effect on carcass dressing percentage and the
proportion of muscles in body weight (Table 3).
