Abstract
The present study was carried out at the poultry research farm, Faculty of Agriculture, Cairo University and El Ahlia Poultry Company, Tanta city, Egypt.
The aim of this work was to investigate if the in-ovo injection of folic acid and glucose into eggs albumen of aged broiler breeders could be useful for improving hatchability and post-hatching productivity.
A total number of 900 hatching eggs were collected from Arbor Acres broiler parents at 55 weeks of age. The eggs were randomly divided into six treatments group four days before incubation; each group was divided into five replicates.
The treatments were as follows:
1. Negative Control: (eggs were not injected or pricked (NC)).
2. Dry Punch Control: (shell and shell membranes were pricked without injecting any solution (DPC)).
3. Positive Control :( eggs were injected with 0.5 ml normal saline (PC)).
4. Folic Acid group: (eggs were injected with 0.5 ml normal saline containing 0.2 mg folic acid (FA)).
5. Glucose group: (eggs were injected with 0.5 ml normal saline containing 125 mg glucose (Glu)).

6. Folic acid with Glucose group: (eggs were injected with
0.5 ml normal saline contain 0.2 mg folic acid and 125 mg glucose (FA + Glu).
The eggs were injected in the albumen under the air sac.
Two eggs from each replicate were selected to evaluate the albumen pH.
After hatching, all un-hatched eggs were examined to calculate the embryonic mortality, fertility percentage, hatchability of total eggs and hatchability of fertile eggs.
After hatching, 540 chicks were randomly taken (90 chicks per each group) then transported to the farm of the Faculty of Agriculture Cairo University. Each treatment was divided into ten replicates. Each replicate was housed separately in several cages in semi-closed system house .
Chick quality, chick weight, chick length and shank length were measured.
Also, body weight, feed intake, feed conversion ratio, growth rate, mortality rate, production number, carcass quality and biochemical analysis of blood.
The most important results obtained were as follows:
1- No significant differences in egg albumen pH between the groups were observed after two days post injection. Four days after the injection, only folic acid could cause a significant decrease in the albumen pH from 9.43 in the negative control group to 9.19.
