ABSTRACT: One important organ that controls broiler development
performance is the stomach.

The stomach is a key organ that regulates the performance of broiler

development. The diets of hens have been supplemented with various feed
additives to improve intestinal health and growth. Butyrate glycerides (BG)
are produced by esterifying ProPhorceSR130, Glycerol, and Butyric Acid.
Glycerol forms ester bonds with up to three butyric acid molecules to
produce butyrin. This robust bond is present in all triglycerides regardless of
pH and can only be broken by the enzyme lipase. Pancreatic lipase
converts tricoryrin to butyric acid in the intestine, but it remains intact in the
stomach and colon. The current study will investigate the effects of varying
amounts of ProPhorceSR130 Butyrate Glyceride on the growth and
composition of broiler carcasses.
Introduction

The use of antibiotic growth promoters (AGPs) to improve the growth

performance of broiler chickens reared in challenging environments dates
back many years. By preventing the growth of dangerous bacteria and the
creation of toxins, they were administered to animals to aid in the
management of the gut microbiota. But the use of AGPs has made bacteria
like Salmonella, Campylobacter, Enterococcus, and Escherichia coli strains
more resistant to antibiotics, which is extremely dangerous for both human
and animal health. The European Commission outlawed the use of
antibiotics as growth promoters in animal feed on January 1 st, 2006. Using
substitute growth promoters was one way to maintain animal health and
improve performance. In animal husbandry, probiotics, prebiotics, enzymes,
phytobiotics, and organic acids are especially well-liked.
Organic acids such as acetic, butyric, propionic, fumaric, and lactic acids
improve avian intestinal health and growth performance. They can be added
to chicken diets as sodium, potassium, and calcium salts in free form,
protected/coated salts, or glycerides. Organic acids have an antimicrobial
effect on the gastrointestinal tract of birds by decreasing the pH of intestinal
digesta, reducing the abundance of pathogenic bacteria, promoting the
growth of Lactobacillus, improving nutrient digestibility, and increasing the
proliferation of intestinal epithelial cells.
Thus, butyric acid seems to have dual effects: it inhibits bacteria and
promotes the growth of Villi. Butyric acid has the strongest bactericidal
action when it is undissociated, much like any other short-chain fatty acid.
Less than 1% of the feed source was found in the upper small intestine,
while about 60% of it remained intact in the crop, according to Bolton and
Dewar’s (1965) observations that free butyrate swiftly vanished in the upper
digestive tract. It is possible that butyrate’s effectiveness will increase if it is
shielded from the upper tract’s rapid absorption. In order to determine
butyrate’s potential for maintaining broiler health and performance, we
evaluated it in this study as a blend of mono-di and triglycerides. Organic
acids include fumaric, lactic, propionic, butyric, and acetic acids
Acids, exert beneficial effects on the gut health and growth performance
of birds. They can be incorporated into poultry diets as sodium, potassium,
and calcium salts, in free form, as protected/coated salts, and as glycerides.
Due to their antimicrobial properties, organic acids affect the gastrointestinal
tract of birds by decreasing the pH of intestinal digestation , reducing the
abundance of pathogenic bacteria, promoting the growth of Lactobacillus ,
improving nutrient digestibility , and enhancing the proliferation of intestinal
epithelial cells.
 Improved Gut Health:
Butyric acid promotes the growth of beneficial bacteria in the gut, such
as Lactobacillus and Bifidobacterium, while inhibiting the growth of
harmful pathogens like Salmonella and Clostridium. This creates a
healthier gut environment for broilers, reducing the risk of digestive
disorders and improving nutrient absorption.
 Enhanced Immune Function:
A healthy gut microbiota is closely linked to immune function. By
supporting the growth of beneficial bacteria, butyric acid can help
strengthen the broilers’ immune systems, making them more resistant
to infections and diseases.
 Better Feed Conversion Ratio (FCR):
Studies have shown that adding butyric acid to broiler feed can
improve feed efficiency, resulting in a lower feed conversion ratio. This
means that broilers can convert feed into body weight more efficiently,
leading to faster growth and reduced feed costs.
 Stress Reduction:
Butyric acid supplementation has also been linked to reduced stress
levels in broilers, possibly due to its positive effects on gut health and
immune function.
 Antimicrobial Activity:
Butyric acid exhibits antimicrobial activity against pathogenic bacteria
such as Salmonella and E. coli, which are common causes of
 infections in broilers. By inhibiting the growth of these pathogens,
butyric acid supplementation can contribute to reducing the risk of
disease outbreaks and improving the safety of poultry products for
consumers.
 Overall:
Butyric acid can be added to broiler production to boost growth
performance, strengthen immune system, improve gastrointestinal
health, and lower microbial contamination. These benefits will
ultimately increase chicken producers’ productivity and profitability. The
goal of the current study was to determine how BA affected the
histological alterations in the intestine and the live performance of
broiler chickens.Because free BA is challenging to control in the feed
manufacturing process, treated feed has a low uptake rate. In this
study, a mixture of mono-, di-, and tri-glycerides of BA was used as the
additive. It smells strongly and is almost completely odorless.
Research Objectives:
1. To improve the growth of broiler without antibiotics.
2. To determine the effect of different levels of Lauric acids on gut health
of broiler.

Material and method:

Experimental Site
The experiment will be conducted at the open farm of Department of Animal
Sciences, College of Agriculture, University of Sargodha.
Experimental Design
Seven hundred-day old broiler chicks will be purchased from a local
hatchery and will be raised at selected site. The chicks will be divided into
four groups, each group will have five replicates and each replicate will have
ten birds. Birds will be divided under the complete randomized design
(CRD)
SHED PREPARATIONS:

Sanitation

Sanitation is a way of life. The most effective sanitizer is hot water, detergent and
brush. Use shovel and scrapper to remove debris, litter and filth in the shed
before sanitizing the shed. Chemical are not substitute for a good cleaning
program. Many food grade chemical sanitizers are used to clean the surfaces.
Chlorine and lye are good germicides relatively inexpensive and must be used on
clean surfaces with no litter or debris. These must be used with care. Sunlight is a
cheap sanitizer and available to all. However the shed is closed, so there is no
sanitization with sunlight.
Pens

Pens are well cleaned and dry. Pens are placed equally. The area of each pen is
10ft2. The litter in pens are equally distributed and covered with sheets of
magazines and pages to avoid picking of bedding material like rice husk which is
indigestible.

Bedding material

Beddding material for broiler is rice husk for growth and welfare purpose.
Broiler performance and welfare were found to be improved when wood
shavings are used for bird rearing. The final ranking of alternatives shows that
the most appropriate broiler litter material under the studied scenario was wood
shavings, followed by rice husk.

Disinfection

It is the process of killing microorganism. Equipments used in poultry shed are

disinfected with disinfectant to kill all type of pathogens or microorganism to
secure birds from all type of pathogens to cause disease. All the feeders and
drinkers are disinfected with 4% formalin solution to antisepticise or kill the
microorganism on the equipments. Disinfection is very crucial factor if it is not
done so that may lead to illness of birds or susceptible of birds with disease.

Commonly used disinfectant materials

• Alcohol

• Chlorine

• Formaldehyde
• Hydrogen peroxide

• Iodophors

• Formalin

• Peracetic acid

Fumigation

Fumigation is a method of pest control or the removal of harmful microorganism

by completely filling an area with gaseous pesticides or fumigants to suffocate or
poison the pest within.

The chemicals used in fumigation are KMnO4 and formalin with 1:2. The 1x
dose of KMnO4 is 17.5 g and formalin 35 ml per cubic meter. This is the
suggested concentration for poultry houses. Because of violent chemical, it is
never use more than 1.2 liters.

Advantages of fumigation

• Quickly eradicate arthropod ore rodents in the structure.

• Penetrate cracks and crevices that may limit the effective sprays and dusts to
control pest.

• Leave no unsightly, odorous or hazardous residues if the site is aerated

properly.

Disadvantage of fumigation

• Highly toxic to most living things, including humans. Breathing even small
amounts of some fumigants can be fatal.
• Require special protective equipment

• Some products are corrosive or flammable.

• Often require warm temperature to be effective.

Completely Random Design

• Simplest design to use.

• Design can be used when experimental units are essentially homogenous.

• Because of the homogeneity requirement, it may be difficult to use this design

for field experiments.

• The CRD is best suited for experiments with a small number of treatments.

Randomization Procedure

• Treatments are assigned to experimental units completely at random.

Every experimental unit has the same probability of receiving any treatment.

Randomization is performed using a random number table, computer, program,

etc

Example of Randomization

You have 4 treatments ( A, B, C & D ) and replicates how many treatments group
we have.

Note that there is no blocking of experimental units into replicates.

Every experimental unit has same probability of receiving any treatment.

Advantages of CRD
 1. Very flexible design (i.e. number of treatments and replicates is only limited
by the available number of experimental units).

2. Statistical analysis is simple compared to other design due to the larger

number of degrees of freedom for the error source of variation.

3. Loss of information due to missing data is small compared to other design due
to the larger number of degrees of freedom for the error source of variation.

Disadvantages

1. If experimental units are not homogenous and you fail to minimize this
variation using blocking, there may be a loss of precision.

2. Usually the least efficient design unless experimental units are homogenous.

3. Not suited for large number of treatments.

Treatment Groups

In a clinical trial, the treatment group usually refers to the group of participants
that receives the treatment under investigation. The treatment group is also
known as the treatment arm.

Group therapy aims to bring about reduction in symptoms such as negative

symptoms, poor motivation, as well as improvent in social functioning, better
adjustment and improved interpersonal relationship skills.

Require special protective equipment.

Bird housing and flock management:

• Before arrival of chicks shed will be sealed for 15-day days

following cleaning, washing, disinfecting with formalin spray.
• Before arrival of chick, house should be fully operated by placing
drinkers and feeders containing water and feed respectively
• Before sealing bedding of about 3inch depth will be prepare by
rice husk

• All the equipment will be washed properly.

• For each replicate pen will prepare having 12.5 square feet area
(2.5*5).
• About 24 hours, before chick arrival brooding area will be
prepared by papers and temperature will maintained at 32 C. after
 arrival. Fresh water will be provided twice a day and feed will offer
properly

Production performance:
Bodyweight:
 Day old chick weight will be done on arrival of chicks at farm, after that
average weight will be taken for every week up to 35 days from each
pen.
 DAY OLD CHICK AVERAGE WEIGHT: 38gram

Feed conversion ratio (FCR):

 The FCR will by calculated by following formula:
 FCR=feed consumed/weight gain
Feed intake:
The feed offered will be 4.5gram per day for per bird. Feed intake will be
calculated after one week at the time of weight by subtracting the amount of
feed refused from the total quantity of feed offered. Feed intake will be
calculated using the following,
Feed intake = Feed offered (g) –( Remaining feed in feeder (g) + Refusal)
Feed conversion ratio (FCR):
The FCR will by calculated by following formula:
FCR=feed consumed/weight gain
FLUSHING:
The purpose of this is to dissolve the yolk of the chicks
There are 2 types of Flushing
1. Through kidney (use sodium benzoate)
2. Through intestine (use sugar)
 At this farm, Flushing is done by giving brown sugar through water.

DOSE
2 gram/liter water

VACCINATION:
Vaccination is the administration of a vaccine to help the immune
system develop immunity from a disease.
Types of vaccine
Live attenuated vaccines
Inactivated vaccines
Live attenuated vaccination
This weekend, immunity is produced by microorganisms. Early immunity
results in a shorter period of immunity in the bird. There is a potential for
virulence to revert. Destroyed the vaccination To create immunity, this
deceased microbe is utilized. Immunity develops later and over a longer
duration. Compared to live vaccines, these are less effective. The virus
cannot possibly revert to its original form.
• The live ND and IB vaccination is administered via water on the fifth day of
the first week.
• The live IBD vaccination is administered via water on the second week’s
twelfth day. The live ND Clone vaccination is administered via water at the
third week (18-day).
