INTRODUCTION

According to the Decree of the President of the
Republic of Uzbekistan PD-100 dated January 24, 2022
on additional measures to support the poultry
industry, it is planned to provide the domestic
consumer market with poultry meat and double the
production of competitive poultry products in
domestic and foreign markets.

Poultry farming is a widespread and rapidly developing
area of livestock. According to statistics, by 2021 in
Uzbekistan will be raised about 90 million birds. 56% of
it is grown on dehkan farms and households, 31% on
specialized poultry enterprises in the system of the
Poultry Industry Association and 13% on farms.
Chickens make up 80 percent of the total number of
poultry in farms and households. Statistics show that

over the past 20 years, the total number of poultry has
increased 4.5 times, chickens 1.9 times, broilers 4.4
times, poultry 6.0 times and eggs 2.9 times.

Relevance and necessity of the topic

. As a result of the

influx of different breeds of birds into the country, it is
necessary to identify and scientifically substantiate the
phenotypic changes in the exterior and economic
usefulness of birds as a result of their own and
offspring

breeding

in

different

technologies,

adaptation to the conditions of Uzbekistan. The result
of this scientific development is the detection of
changes in the live weight and exterior of birds, which
in the future will allow to carry out selection work on
these indicators from the beginning of life of birds.

The aim of the study

: To determine the growth and

development of broiler chickens raised in different
categories of farms, as well as to increase the
production of chicken products.

OBJECTIVES OF THE STUDY

Experiments determine the productivity and
domestic conditions of meat chickens from 1 to 40
days on the basis of their useful economic
characteristics, indices and coefficients.

In this case, broiler chickens are fed and stored in
industrial and domestic conditions. In the
experimental groups, phenotypic changes in the
useful traits of chickens were detected from
incubation to slaughter.

Feeding of broiler chickens in

different

technologies, incubation differences by seasons
are studied.

The experiment will study the growth and
development of broiler chickens raised in industrial
enterprises and households.

Methods of storage and feeding conditions of
chickens, their phenotypic changes under the

influence of light and their effects on the external
div structure and div base bones are
determined.

Scientific novelty of the research:

Productivity of broiler poultry focused on meat
productivity in different feeding technologies,
phenotypic

indicators,

constitutional

types,

external-internal indicators, meat qualities are
determined;

Different technologies determine the dependence
of the external and productivity of poultry on
different technologies, capture-natural conditions,
types of production;

Changes in meat productivity and product quality,
exterior-interior, div composition of imported
broiler chickens in Uzbekistan are scientifically
based and indicators of their interdependence are
determined.

RESEARCH METHODS

The accepted scientific researches use the generally
accepted zootechnical, anatomical-morphological,
veterinary clinical, statistical and comparative
methods. Research includes observations and
measurements, biochemical analysis of poultry
products by veterinary and sanitary methods.

Productivity of birds and their offspring in different
feeding and feeding technologies, phenotypic
indicators, constitutional types, indicators of
changes in external and internal indicators, egg
and meat qualities are determined;

The work being done

: The special importance of bone

diameter as a factor determining its strength in the
early period of postembryonic development after the
ovulation period is mainly due to the slow progress of
the process of hard ossification of the soft diaphysis

during this period. The tubular bones are still very soft,
elastic, and plastic, especially at the junction of the
pineal gland and diaphysis (bone growth). An increase
in the diameter of a bone is almost a sufficient
response to maintain its strength, a reaction that must
be genetically inherited. Therefore, the lack of
differences in the growth rate of the live weight of the
chick and the bone strength that supports it can lead
to pathological changes such as bone fragility, leg
flexion, flexion of the hip and lower leg bones. [9,
20,26].

As we can see from the above, in the last 40-30 years
the conditions for feeding and keeping birds in an
industrial way or in homes have improved. The
application of genetic changes in the concentration

and selection of these factors significantly altered the
birds. As a result, their different genotypes began to
form many phenotypes of birds as environmental
characteristics changed.

The diversity of technological methods alters the
habitat of birds and serves as an important factor in
their phenotypic formation. This, in turn, leads to
different results and differences in the manifestation
of their genetic productivity potential. In recent years,
with the introduction of different breeds and
technologies of poultry in Uzbekistan for various
reasons, in the hot conditions of the country in
different farms and households there is a need to
conduct research on the reproduction of poultry
products by early selection of their phenotypes and
high-yielding birds.

All experiments are based on the recommendations of
“Methods of conducting zootechnical experiments in
animals and birds”.

*- feeding birds according to their age, live weight,
products;

**- according to the season, from late autumn to early
spring, it is illuminated on the basis of technology.

The duration of the experiments is planned to be based
on the technology of feeding broiler chickens. In
addition, during the experiments, the cost of feed for
each group is studied, and finally the economic
indicators are analyzed separately.

CONCLUSION

In short, depending on the appearance of broiler
chickens, it is possible to know that it is meaty, healthy.
The fact that he was blown up, his legs were covered
with flesh, and his eyes were shining was also a sign of
his health. Therefore, it is necessary to know the signs
of their phenotype.
