Abstract:

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, carcass and organ weights
