Does in Ovo Injection of Two Chicken Strains with Royal Jelly Impact Hatchability Post-Hatch Growth Performance and Haematological and Immunological Parameters in Hatched Chicks?

摘要

Simple SummaryThe present investigation examined improvements in egg hatchability and the growth performance of hatched chicks of two strains upon injection with increasing concentrations of royal jelly (RJ). The results showed positive effects of RJ injection on all parameters. Limited impacts of the different chicken strains were observed on the tested parameters. The study revealed that varying the chicken strain could alter the response to the in ovo injection with RJ.
