Abstract: A 6-week experiment was carried out to evaluate the performance and serum enzymes of broilers
fed graded levels of Parkia biglobosa fruit pulp with or without enzyme supplementation. A total
of 189 day old broiler chicks of Marshal strain were allotted to 7 treatments of 3 replicates each. A
replicate contained 9 chicks. Diet that did not contain Parkia biglobosa fruit pulp served as the control.
Diets containing 5, 10 and 15% Parkia biglobosa fruit pulp were in T1, T2 and T3, respectively.
These three diets were not supplemented with exogenous enzymes. Diets T4, T5 and T6 contained
5, 10 and 15% Parkia biglobosa fruit pulp, respectively. These latter diets were each supplemented
with 0.4 gram Polyzyme® per kg diet. The results showed that starter broilers fed control diet had the
best feed conversion ratio. Starters fed enzymes supplemented 5% Parkia biglobosa fruit pulp diet
had slightly improved feed conversion ratio than those fed unsupplemented 5% Parkia biglobosa fruit
pulp diet. Addition of enzymes to 15% Parkia biglobosa fruit pulp diet elicited improved (P = 0.0002)
final body weight and average daily gain (P = 0.005) of finishers relative to those fed unsupplemented
15% Parkia biglobosa fruit pulp. Exogenous enzymes enhanced crude fibre digestibility (P = 0.0005)
for broilers fed 10% and 15% Parkia biglobosa fruit pulp. Feeding dietary Parkia biglobosa fruit pulp
to broiler chickens significantly (P = 0.007) increased serum alkaline phosphatase except for those
fed 15% Parkia biglobosa fruit pulp. Conclusively, feeding 5% Parkia biglobosa fruit pulp to broilers
supported maximum final body weight. However, broilers fed 15% Parkia biglobosa fruit pulp diet
required enzyme supplementation for improved final body weight and crude fibre digestibility.
