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 

body structure and body 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, body 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.
