Abstract
ABSTRACT
The purpose of the study was to determine the effectiveness of dietary supplements of papaya leaf meal
(Carica papaya) and black cumin (Nigella sativa) seeds on the production index and hematological status
of commercial broiler chicken. T1 (Control), T2 (antibiotic), T3 (2% PLM: Papaya Leaf Meal), T4 (1%
BCS: Black Cumin Seed) and T5 (1% of each PLM & BCS) were the five treatment groups that the 150day-old
Cobb
500
straight
run
chicks
were
randomly
assigned.
Ten
chicks
were
used
in
each
of
the
three
replications
of
each
treatment.
The
findings
demonstrated
that
feeding
broilers
supplements
of
PLM
and
BCS
did not significantly (p>0.05) affect feed consumption (FC) (g), final live weight (g) and feed
conversion ratio (FCR) when compared to the control and antibiotic group. FC was found to be
numerically (p>0.05) higher in the control group than in the other groups. However, the T3 group of
birds given 2% PLM had superior ultimate live weight and an improved FCR value compared to
antibiotic, control, and the values of the other groups, which were statistically insignificant (p>0.05).
The relative weight of the spleen in various groups was unaffected (p>0.05) by dietary supplementation
with PLM and BCS. But the T3 (2% PLM) group had significantly (p<0.05) increased bursa weight (g).
The concentrations of glucose and cholesterol were similar across all groups (p>0.05), while the group
receiving 2% PLM supplements had relatively lower cholesterol levels (mg/dl). Moreover, the
supplemented groups with PLM and BCS revealed a significant (p<0.05) increase in the hematological
parameters red blood cell (RBC), white blood cell (WBC), lymphocyte, and packed cell volume (PCV)
as compared to the antibiotic and control groups. The final live weight, FCR, immune organ weight, and
blood indices were all improved in birds fed a meal supplemented with 2% PLM, leading to superior
results.
