Genetic Characterization and Identification of chicken breeds in Egypt


Introduction

The information gained from the Egyptian chicken breeds should serve decision making for both conservation and for improved use in different production environments. Monitoring and characterization will help for prioritization of breeds preservation. this should be standard and comparable for making it possible to classify breeds and strains on the basis of the emergency of their conservation, their genetic and phenotypic traits and according to their suitability to different production systems and environment.  In Egypt, comprehensive national or regional survey of chicken breeds used for potential use in agriculture is not yet carried out. It is highly expected that some Egyptian chicken populations are vulnerable or rare; some of them are even critical or endangered. Therefore, establishment of a mechanism to survey chicken breeds in Egypt is a must and of top priority at the national level. Characterization is the first step to improvement of chicken breeds. It is especially useful for the genetic diversity study, which is a very efficient economic trend in animal research stations and animal breeding programs.

Project objectives

  1. Conduction of biochemical and molecular genetic fingerprinting of Egyptian chicken breeds
  2. Calculation of genetic homogeneity within each breed
  3. Calculation of genetic similarities and genetic distances among these breeds 
  4. Construction of phylogenetic relationships between breeds
  5. Availability of data that support nucleus herds construction
  6. In Situ preservation containing a center for In Vivo preservation (embryos- semen- ova – pure genetic materials).

Project output

  1. Chicken breeds data base in Egypt
  2. Phylogenetic tree and genetic dendrograme of all chicken breeds
  3. specific biochemical and molecular genetic markers
  4. Establishment of marker assisted selection programs
  5. Establishment of nucleus herds carrying favorable traits
