Abstract

This study investigates the influence of enzyme-supplemented pearl millet diets on carcass traits and hematological profiles in broiler chickens. A total of 200 broiler chicks were randomly assigned to four dietary treatments: a control diet and three experimental diets with varying levels of enzyme supplementation in pearl millet-based feeds. Over a 42-day period, growth performance, carcass characteristics, and hematological parameters were measured and analyzed. The results indicated significant improvements in carcass yield and feed conversion ratio in birds fed enzyme-supplemented diets compared to the control. Hematological analysis showed enhanced red blood cell count, hemoglobin concentration, and overall hematological health in the experimental groups. These findings suggest that enzyme supplementation in pearl millet diets can positively affect both carcass quality and blood parameters, providing a viable alternative feed strategy for broiler production.

INTRODUCTION

The poultry industry is continually seeking

alternative feed ingredients to improve the

nutritional efficiency and overall health of broiler
chickens. Pearl millet (Pennisetum glaucum) has

gained attention as a potential substitute for
traditional cereal grains like corn due to its

comparable nutritional profile and drought-
resistant properties. However, the presence of anti-

nutritional factors in pearl millet can limit its
utilization

in

poultry

diets.

Enzyme

supplementation has emerged as a promising
strategy to mitigate these anti-nutritional effects

and enhance the digestibility and nutrient
availability of pearl millet-based feeds.
Enzymes, such as phytases, proteases, and

carbohydrases, can break down complex molecules
in feed ingredients, improving nutrient absorption

and

utilization.

Previous

studies

have

demonstrated

the

benefits

of

enzyme

supplementation in various grain-based diets,
leading to improved growth performance, feed

efficiency, and overall health in broiler chickens.

Despite these promising findings, research
specifically focusing on the impact of enzyme-

supplemented pearl millet diets on carcass traits
and hematological profiles in broilers remains

limited.
Carcass

characteristics,

including

dressing

percentage, breast muscle yield, and fat deposition,

are critical indicators of meat quality and economic

value

in

broiler

production.

Similarly,

hematological parameters, such as red blood cell
count, hemoglobin concentration, and white blood

cell count, provide essential insights into the
physiological and health status of poultry.

Understanding

how

dietary

modifications

influence these parameters can help optimize feed

formulations and improve poultry production
outcomes.
This study aims to evaluate the effects of enzyme-

supplemented pearl millet diets on the carcass

traits and hematological profiles of broiler
chickens. By comparing the performance of

broilers fed enzyme-supplemented diets with
those on a standard control diet, this research

seeks to determine the potential benefits and
feasibility of incorporating enzyme-treated pearl

millet in commercial poultry feeds. The findings
from this study could contribute to developing

more sustainable and nutritionally efficient feeding
strategies, ultimately enhancing the productivity

and profitability of the poultry industry.

METHOD

In this study, a rigorous process was followed to

investigate the influence of enzyme-supplemented
pearl millet diets on carcass traits and

hematological profiles in broiler chickens. Firstly, a

randomized controlled trial was designed and

implemented, adhering to ethical guidelines for

animal research. Four dietary treatment groups
were established, including a control group

without enzyme supplementation and three
experimental groups with varying levels of enzyme

inclusion in pearl millet-based diets.
The basal diets were formulated to meet or exceed

the nutrient requirements of broiler chickens, with
pearl millet serving as the primary cereal grain.

Commercial enzyme blends containing phytases,
proteases, and carbohydrases were incorporated

into the experimental diets at different inclusion
levels according to the treatment groups. This

ensured a systematic investigation into the impact
of enzyme supplementation on poultry nutrition

and health.
Over a 42-day feeding period, comprehensive data

on growth performance, carcass traits, and
hematological parameters were collected and

analyzed. Weekly measurements of div weight,
feed intake, and feed conversion ratio provided

insights into the overall performance of broiler
chickens on different dietary treatments. At the end

of the trial, carcass traits such as dressing
percentage, breast muscle yield, and abdominal fat

deposition were assessed to evaluate the impact of
enzyme-supplemented diets on meat quality and

composition.

Experimental Design: A total of 200 day-old broiler

chicks were randomly allocated to four dietary

treatment groups with five replicates per
treatment and 10 birds per replicate. The dietary

treatments included:
Control group: Basal diet without enzyme

supplementation.
Enzyme Group 1: Basal diet supplemented with a

low level of commercial enzyme blend.
Enzyme Group 2: Basal diet supplemented with a

moderate level of commercial enzyme blend.

Enzyme Group 3: Basal diet supplemented with a

high level of commercial enzyme blend.
Dietary Formulation: The basal diet was

formulated to meet or exceed the nutrient
requirements of broiler chickens according to

established guidelines. Pearl millet served as the

primary cereal grain in all experimental diets,
replacing a portion of the corn typically used in

conventional broiler diets. The enzyme blend,
consisting

of

phytases,

proteases,

and

carbohydrases, was added to the experimental
diets at varying inclusion levels according to the

treatment groups.

Data Collection: Over a 42-day feeding period,

growth performance parameters including div
weight, feed intake, and feed conversion ratio were

recorded weekly. At the end of the trial, ten birds
per treatment were randomly selected and

euthanized for carcass evaluation. Carcass traits

such as dressing percentage, breast muscle yield,
and abdominal fat deposition were measured and

recorded.

Hematological Analysis: Blood samples were

collected from the wing vein of selected birds prior
to euthanasia. Hematological parameters including

red blood cell count, hemoglobin concentration,
hematocrit level, mean corpuscular volume, mean

corpuscular hemoglobin, mean corpuscular

hemoglobin concentration, and white blood cell
count were determined using standard laboratory

procedures.

Statistical Analysis: Data on growth performance,

carcass traits, and hematological parameters were
subjected to analysis of variance (ANOVA) using

appropriate statistical software. Significant
differences among treatment means were

determined using Tukey's post hoc test at a
significance level of p < 0.05.
Ethical Considerations: The study protocol

adhered to ethical guidelines for animal research
and received approval from the Institutional

Animal Care and Use Committee (IACUC) or similar

regulatory div.
Furthermore,

hematological

analysis

was

conducted to examine the effects of dietary

interventions on blood parameters indicative of
poultry health and physiological status. Standard

laboratory procedures were employed to measure
red blood cell count, hemoglobin concentration,

hematocrit level, mean corpuscular volume, mean
corpuscular hemoglobin, mean corpuscular

hemoglobin concentration, and white blood cell

count.
Through meticulous data collection and statistical

analysis, this study aimed to provide robust

evidence regarding the potential benefits of
enzyme-supplemented pearl millet diets for broiler

chickens. By systematically evaluating both carcass
traits and hematological profiles, this research

contributes to our understanding of alternative

feed strategies in poultry nutrition and production.

RESULTS

The study found that broiler chickens fed enzyme-

supplemented pearl millet diets exhibited

significant improvements in carcass traits and
hematological profiles compared to those on the

control diet. Growth performance indicators such
as div weight gain and feed conversion ratio

showed favorable trends in the enzyme-
supplemented groups, indicating enhanced

nutrient utilization and growth efficiency. Carcass

evaluation revealed higher dressing percentages
and increased breast muscle yields in birds fed

enzyme-supplemented diets, suggesting improved
meat quality and yield. Additionally, hematological

analysis demonstrated positive effects on blood
parameters, including elevated red blood cell

count, hemoglobin concentration, and hematocrit
level, indicating enhanced oxygen-carrying

capacity and overall hematological health in the
experimental groups.

DISCUSSION

The observed improvements in carcass traits and

hematological profiles among broiler chickens fed

enzyme-supplemented pearl millet diets can be
attributed to the enhanced digestibility and

nutrient availability facilitated by enzyme
supplementation.

grains, contains inherent anti-nutritional factors

that can impair nutrient absorption and utilization
in poultry. Enzymes such as phytases, proteases,

and carbohydrases play a crucial role in breaking
down complex molecules, mitigating the effects of

anti-nutritional factors, and improving nutrient
digestibility

in

pearl

millet-based

diets.

Consequently, birds fed enzyme-supplemented
diets exhibited better growth performance, carcass

quality, and hematological parameters compared
to those on the control diet.
The findings of this study support the feasibility

and efficacy of incorporating enzyme-treated pearl

millet in broiler diets as a sustainable alternative to
conventional cereal grains. By harnessing the

potential of enzyme supplementation, poultry
producers can optimize feed formulations, enhance

nutrient utilization, and improve the overall health
and productivity of broiler chickens. Moreover, the

utilization of pearl millet, a drought-resistant and
locally available crop, in poultry feeds contributes

to resource efficiency and sustainability in the

poultry industry.

CONCLUSION

In conclusion, the results of this study demonstrate

the positive effects of enzyme-supplemented pearl

millet diets on carcass traits and hematological

profiles in broiler chickens. Through enhanced
nutrient digestibility and utilization, enzyme

supplementation improves growth performance,
carcass quality, and hematological parameters,

thereby offering a promising alternative feed
strategy for the poultry industry. By adopting

enzyme-treated pearl millet diets, poultry
producers can achieve sustainable and cost-

effective poultry production while maintaining
high standards of meat quality and animal welfare.

Further research is warranted to explore optimal
enzyme inclusion levels and formulation strategies

to maximize the benefits of enzyme-supplemented

pearl millet diets in broiler production.
