An experiment was carried out to evaluate the effect of some antistress agents on the performance of broiler breeder hen during hot summer. The study revealed that groups fed with antistress agents laid more eggs compared to the control group. Difference between treatments were found to be significant for egg weight, shell thickness but not for shell weight. The group fed with Venlyte, recorded higher egg weight, higher shell thickness compared to other groups.
