The results of the study showed that: A significant increasing (p <0.05) in treatment with aqueous extract of neem seed in concentration 20 to 40 ml / liter of drinking water in body weight (g) and body weight gain , and recorded the better rate of feed conversation ratio at the age of 5 and 6 weeks compared to the control group. Significant statistical correlation (p<0.05) is seen for the relative heart weight in all the treated groups, while non-significant differences was noticed for the relative liver weight.
