Allocated microflora in different poultry farms and various technological trends and control of bacterial diseases of birds

Abstract

Industrial poultry tends to significantly change in recent years through the use of highly productive poultry crosses. Thus it is necessary to carry out all technological and veterinarian conditions for the maintenance and feeding of a bird. If the above conditions are not met, there are prerequisites for the activation of opportunistic microflora. Thus, the study of the spectrum of microorganisms isolated from poultry farms of different technological directions is an objective necessity. Escherichia coli occupies a dominant position among all types of isolated microorganisms. This fact makes it difficult to conduct timely diagnostic, health and therapeutic measures. The most effective way to combat diseases of infectious nature is a specific prevention - vaccination. Studies were carried out in conjunction with the Saratov scientific and research veterinary institute and created a preventive drug based on the isolated protein fractions from the thermolabile and thermostable strains of Escherichia - a live vaccine against colibacteriosis of birds. there are both inactivated and live vaccines, such as vaccine preparation from a strain strain of E. coli. “B-5” at the moment ". The use of the above-mentioned vaccine contributes to the effective implementation of the prevention of colibacteriosis of chickens, including early age (up to 10 days), which will ensure the well-being of the bird-head against colibacteriosis, and significantly reduce the economic losses from this disease.
