Effects of some alcoholic extracts of propolis in ovulation and fertility rate of the ovary and oviduct in quail

This research was carried out in quail in a special place of the laboratory from 6/9/2018 through 23/11/2018 to detect effects of adding the alcoholic extract of propolis on the ovulation and fertility rate in the ovary and oviduct of quail. 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.
