تحليل التمايز الوراثى بالميكروستالايت لسلالتين من الدجاج المحلى مقارنة بالسلالة الاجنبية هاى لاين

The
present study was conducted on two Egyptian native breeds (Dandarawi
and Fayoumi) and commercial laying hens (brown Hy-line) to estimate
genetic differentiation using microsatellites and their association
with egg production traits. Five microsatellite markers, four located
on Z chromosome and one located on chromosome 1 were used in this
study. The present results indicated that the Hy-line strain had
significantly better egg production parameters and feed conversion
ratio compared to two native breeds. Inversely, the two native breeds
had better eggshell quality measurements compared to Hy-line hens. The
five microsatellite genetic markers applied in the present study
success to reveal high degree of polymorphism among the three breeds
used here. Also, a clear discriminating power was achieved in
differentiation among studied chicken populations. The genetic distance
revealed that Fayoumi breed is mostly related to Hy-line strain more
than Dandrawi breed.
