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, myostatinpro-peptide (MyoPro) gene on growth performance of Fayoumi chicken. A total number of 200 Fayoumifertilized pure breed eggs were obtained from EL-Tkamoly poultry project - EL-Azab – Fayoum. Eggs weredivided into two equal groups. Group 1(control group, n=100) was injected with saline, and group 2 (treatedgroup, n=100) injected with Myo-pro gene. Growth parameters were recorded (body weight, body weightgain, feed consumption per group was measured for calculating feed conversion ratio). The obtained resultsrevealed that injection of myo-pro to Fayoumi eggs resulted in highly significant increase in body weight andweight gain during all experimental period when compared with control group. Feed conversion ratio ofMyo-pro injected group was significantly lower than control group. However, food intake showed nosignificant change between the two groups. From the obtained results, injection of Myo-Pro gene causingmarked increase in body weight gain and improvement in feed conversion ratio without change in foodintake in fayoumi chicken.
