ABSTRACT
This study was conducted in two experiments at the Al-Anwar Poultry Company hatchery from November 11, 2023, to December 2, 2023, to demonstrate the effect of Lysophospholipid (LPL) injection on hatching eggs on the quality of hatched chicks. A total of nine hundred eggs were used in this study. All the eggs were set in an automatic incubator at the same time. On the 12th day of embryonic age, half of the eggs (450 eggs) were divided into 6 groups (75 eggs per group). The first egg group was kept in the incubator without treatment and was a negative control (NC). The second egg group was injected with 0.3 ml of NACL solution and served as a positive control (PC).In contrast, the 3rd, 4th, 5th, and 6th egg groups were injected with phospholipids at a concentration of 1, 2, 3, and 4% (0.3 ml/egg), respectively. On the 18th day of embryonic age, the second half of the egg was divided and treated similarly to the first half of the egg. The results showed that injecting at 12 days of embryo age resulted in a significant superiority (P < 0.05) for groups G1, G4, and G5 regarding the hatching rate. The embryonic mortality rate was significantly reduced in groups G1 and G5. The percentage of pipped eggs and dead pipped chicks was significantly increased in the G2 and G3 groups, respectively. Chick activity increased significantly in all treatments compared to treatment T2. When injected at 18 days of age of the embryos, there was a significant (P < 0.01) improvement for G6 groups in the hatching rate and embryonic mortality rate. Additionally, all LPL injection groups showed significant improvements in the weight of hatched chicks, activity, and leg length compared with the control groups. In the chicks’ length, chick activity increased significantly (P < 0.01) in the G4, G5, and G6 groups. Wing length also increased significantly in the G4 and G5 groups, and tonic immobility improved significantly (P < 0.05) in the G3 and G6 groups.
