Effects of In-ovo Injection of Different Nutrients on the Hatchability and growth Performance in Broilers

The aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of Ross 308 broiler chicks. Fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), amino acids, albumin 20%, dextrose 20% and dextrose 10% . The injections were made on d 17.5 of the  incubation period, and the hatch rate of fertilized eggs were recorded. Post-hatch performance of was determined weekly up to day 42. On d 42 of age, the weight of carcasses, thighs, wings, breast muscle, back and neck were determined. The results showed that in ovo injection of albumin increased body weight (P
