Effect of in Ovo Injection of MyoPro Gene on Growth Parameter in Fayoumi Chicken

Abstract

The current study aimed at evaluation the effects of in ovo injection of the myostatin inhibitor, myostatin pro-peptide (MyoPro) gene on growth performance of Fayoumi chicken. A total number of 200 Fayoumi fertilized pure breed eggs were obtained from EL-Tkamoly poultry project -EL-Azab -Fayoum. Eggs were divided into two equal groups. Group 1(control group, n=100) was injected with saline, and group 2 (treated group, n=100) injected with Myo-pro gene. Growth parameters were recorded (body weight, body weight gain, feed consumption per group was measured for calculating feed conversion ratio). The obtained results revealed that injection of myo-pro to Fayoumi eggs resulted in highly significant increase in body weight and weight gain during all experimental period when compared with control group. Feed conversion ratio of Myo-pro injected group was significantly lower than control group. However, food intake showed no significant change between the two groups. From the obtained results, injection of Myo-Pro gene causing marked increase in body weight gain and improvement in feed conversion ratio without change in food intake in fayoumi chicken.
