A study was carried out to evaluate the toxicity and effects of aqueous Azadirachta indica leaf extract (ALE) on the performance, haematology and serum biochemistry parameters of broiler chicks. One hundred and forty four, seven-day old broiler chicks were randomly assigned to four treatments which contained 0, 20, 40 and 60ml ALE per litre of water representing T1, T2, T3 and T4 respectively in a Completely Randomized Design experiment. Each treatment was replicated three times with five birds in each replicate. Feed and water were provided ad libitum. There was no significant (P>0.05) difference in weight gain, feed and water intakes, feed conversion and protein efficiency ratios among the treatment groups. Also no significant (P>0.05) effect was observed in the survival of birds treated with ALE and the control. ALE did exert any significant influence (P>0.05) on the haematological and serum indices of the birds. In conclusion, results of this study indicate that aqueous ALE could therefore, be used in broiler chicks production without any deleterious effect on the performance and blood indices of the birds.
