Effects of in-ovo chrysin injection to quail eggs on hatchability, production parameters, and immunity
This study investigated the effects of in ovo Chrysin injection on hatchability, embryonic mortality, body weight, feed conversion ratio (FCR), and immune responses in quails. A total of 720 fertilized eggs were randomly assigned to four groups: Control (0.1 mL distilled water) and Chrysin-treated g...

| Summary: | This study investigated the effects of in ovo Chrysin injection on hatchability, embryonic
mortality, body weight, feed conversion ratio (FCR), and immune responses in quails.
A total of 720 fertilized eggs were randomly assigned to four groups: Control (0.1 mL
distilled water) and Chrysin-treated groups (0.1 mL containing 0.25 mg, 0.50 mg, or
0.75 mg Chrysin per egg). Hatchability and hatching efficiency were unaffected by
Chrysin treatment, although late embryonic mortality was significantly higher in the
0.75 mg group. Post-hatch evaluations showed significantly greater body weights on
days 14 and 42 in the 0.25 mg and 0.50 mg groups compared to the control. These
groups also exhibited improved FCR values, while feed intake remained unchanged
across groups. Immunological analysis revealed a significant increase in IgA levels
in the 0.75 mg group, with no significant effects on IgM or IgG levels. Overall, in ovo
Chrysin supplementation at 0.25 mg and 0.50 mg enhanced growth performance and
feed efficiency without adversely affecting hatchability, while the 0.75 mg increased
embryonic mortality, indicating a need for dose optimization. These findings suggest
that Chrysin holds potential as a biotechnological tool in poultry production, though
further studies are required to refine dosing strategies and investigate its long-term
impacts on performance and immunity. |
