Eight groups and repetitions for each group were employed. Groups were homogenous in weights and were placed in 13 cages. Each group consists of 10 quail. In the first treatment (T₁), quails were fed on regular feed without supplementation. Quails were fed in the second treatment (T₂) by adding the alcoholic extract of propolis in an amount of 200 mg kg^-1. The third group (T₃) was the same as normal food after adding propolis alcoholic extract at a concentration of 400 mg kg^-1. The results of the histological study showed that T₃ (adding 400 mg kg^-1) led to a physiological reproductive activity and an increase in the ovulation rate (%) than the normal limit and an elevation in the fertility rate without the appearance of unpleasant side effects or pathological or macroscopic or histological changes. The alcoholic extract of propolis led to the growth and increase of the ciliated and ciliated epithelial layer cells in their numbers and shapes in the oviduct, despite the rapid growth and rapid ovulation, unless there was no change in the shape of the egg or a change in its components. https://cjes.guilan.ac.ir/article_6496_5c6ed85bc78e83d3e582f4259aad58fc.pdf
