Name of the project: Development of modern biotechnologies for assessment of expression of genes in connection with productivity and resistance to diseases poultry farming

Strategy for Scientific and Technological Development Priority Level: г

Goals and objectives
Research directions:

  • Creation of modern biotechnologies for assessment of expression of genes related to productivity and resistance of birds against unfavorable factors
  • Development of a system for monitoring pathogenic bacteria at various stages of the technological process of hen farming
  • Assessment of impact of fodder supplements of various types on bowel microflora and productivity of layer farming
  • Development of a system for preventing bacterial pathogens in layer hens based in usage of probiotics and phytobiotics
  • Testing of developed technologies in functioning paltry farms.

Project objective: Complex development of new molecular and genetic technologies for analysis of expression of genes playing the key role in ensuring productivity and resistance to diseases in hens as well as for assessment of bowel microflora and fodder, impact of fodder supplement

The practical value of the study

According to the main results obtained in the course of the performed studies for 2017–2020, a review of the methods and protocols for studying differential expression by full transcriptomic sequencing (RNASeq) of genes associated with traits of economic importance was carried out, and the corresponding technology was developed.

The resulting list of 34 selected genes involved in the formation of productivity traits and immunity of laying hens, and the developed method for determining the expression of genes associated with productive traits and resistance indicators in laying hens, using RT-PCR, made it possible to assess the effect of feed additives of various types on the microflora intestines, productivity and resistance in the egg type poultry.

Results of studying the development of gastrointestinal tract microbiocenosis in embryos of industrial crosses during embryonic development and at different periods of oviposition, as well as the results of T-RFLP analyzes of the contents of the intestines of chickens and the results of using the developed system for monitoring pathogenic bacteria at various stages of the technological process of growing laying hens allow for a targeted correction of the microbiocenosis of laying hens using feed factors to increase the productivity in the egg type poultry.

In the course of studying the effect of the phytobiotic Intebio® and the probiotic Liquipro® on the microflora of the digestive tract of poultry, the microbiocenoses of the digestive tract of chicks and adult chickens were tested. Protocols for studying the microflora of poultry intestinal contents by T-RFLP and NGS sequencing and protocols for testing the expression of genes associated with poultry productivity and immunity (two interleukin genes, three gallinacin genes, caspase gene, etc.) in response to salmonella infection were obtained.

The study of the relationship between the use of feed additives, gastrointestinal microflora, productivity and expression levels of productivity genes was carried out. The effects of the used feed additives (prebiotics and phytobiotics) on the productivity in hens of an egg layer cross and on the expression of genes associated with productivity and immunity have been described.

Mathematical models of the dependence of the productivity and expression of associated genes of poultry on the composition of the diet and intestinal microbiocenosis have been developed.

Based on the results of the development of a system for monitoring and preventing pathogenic bacteria by correcting the diet of laying hens with the help of antimicrobial additives (probiotics, phytobiotics), the appropriate guidelines were published with a description of the developed system.

In 2020-2021, the scientific research is aimed at conducting industrial experience to study the effect of a feed additive on gene expression (related to productivity and resistance) in laying hens and setting up a feeding experiment in industrial crosses of laying hens exposed to stress, when using an antimicrobial feed additive.

In the process of carrying out research within the framework of the mega-grant, scientific approaches and practical methods of managing the intestinal microbiota were developed. The developed technology was tested in the conditions of industrial egg production, and its adaptation to the conditions of modern egg poultry farms in Russia was conducted. At the same time, special attention is paid to the organic integration of the developed microbiota management technology into the already existing technological approaches and techniques of egg poultry farming. Particular attention is paid to the synergistic interaction of various feed additives and their effect on the intestinal microbiota in order to maximize the genetic potential of modern egg poultry crosses.
