Abstract

Haematological parameters and serum metabolites were determined in 42 days old broilers fed
diets in which their maize content were replaced with iburu (Digitaria iburua) offal in a
completely randomized design. The study was conducted at the Poultry Unit of the Teaching and
Research Farm Federal University of Technology Akure, Ondo State, Nigeria. Six broiler diets
designated T 1 , T 2 , T 3 , T 4 , T 5 and T 6 were formulated such that T1 which served as
control contained 0% IO, while diets T 2 -T 6 had their maize content replaced with IO at 5.0%,
7.5%, 10.0%, 12.5% and 15.0%%, respectively. Only red blood cell count (RBC) of all
haematological variables measured was significantly (P<0.05) influenced by the dietary
treatments. Birds fed T4 had the highest RBC (4.51±0.32mmx10-6) counts; followed by those fed
T3, T5 and T6 (4.38±0.32mmx10-6, 4.47±0.32mmx10-6 and 4.49±0.32mmx10-6 respectively) while
those fed T1 and T2 had the least (3.15±0.32mmx10-6 and 3.25±0.32 mmx10-6, respectively).
Only cholesterol was significantly (P<0.05) influenced by the dietary treatments among the
serum metabolites measured. Birds fed T1 and T2 had higher cholesterol (135.21±0.1313mg/dl
and 135.12±0.1313mg/dl, respectively) levels than those fed T3, T4, T5 and T6
(127.74±0.1313mg/dl, 127.01±0.1313mg/dl, 125.56±0.1313mg/dl and 121.69±0.13mg/dl,
respectively) levels. It can be concluded that the replacement of maize with iburu offal up to
15.00% maize had no deleterious effects on the haematological and serum biochemical indices
viz a vis the health status of broiler broiler chickens.
