The effects of feeding graded levels (0, 5, 10, 15 and 20%)
of Neem leaf meals (NM) to broiler chicks on live weights,
carcass and organ weights and blood constituents was
investigated. Two hundred and forty (240) 7 days-old unsex
broiler chicks (Arbor acres) were randomly allocated to five
treatments of 48 birds each, replicated four times with 12
birds each in a completely randomized design. Feed and water
were given ad-libitum till 56 days. The results of the live
weights and carcass and organ weights decreased with
increased NM inclusion in the diets. Haematological
constituents were not affected (P>0.05) except the packed
cell volume while the serum biochemical indices of birds fed
20 % NM diets were decreased (P<0.05) compared with those
fed control, 5 %, 10% and 15% NM diets. Inclusion of 15% NM
in broiler chicks’ diet had no adverse effects on live,
carcass and organ weights and immunity responses. NM needs
further treatment to improve inclusion levels beyond 15 % in
broilers’ diets.

Keywords: Azadirachta indica, broilers, immunity,
