The Action Of Myo-Pro gene On The Morphology Of Skeletal Muscle Of Fayoumi Chicken

Abstract

The aim of the present study was to evaluate the changes in skeletal muscle which may occur after in ovo injection of Myo-Pro gene . A total number of 200 Fayoumi fertilized pure breed eggs were obtained from EL-Tkamoly poultry project - EL-Azab – Fayoum and divided into two equal groups. Control group, n= 100 that was injected with saline, and treated group n = 100 was injected with MyoPro gene. To check both possibilities, we examined the gastrocnemius muscle fibers number and diameter (cross sectional area). The results revealed that Chicken hatched from Myo-Pro injected eggs showed a significant increased muscle masses. This increase in muscle mass and subsequently meat production is due to hypertrophy rather than hyperplasia. From the obtained results, using Myo-Pro gene causing improvement in skeletal muscle fiber (diameter and number) in Fayoumi chicken.
