Characterization of pregnancy rate and offspring counts in Wistar rats females after experimental treatment with propolis extract

The current study was carried out on Twenty (20) female white rats aged 105-110 days; sourced from the Animal House/College of Veterinary Medicine/University of Al-Qadisiyah. The animals used in the study were equally divided into two groups; the treatment group (T) which made up of 10 female white rats, the animals of this group were weighed and dosed daily with 40 milligrams/kg of the alcoholic extract bee propolis for a period of 30 days and, the control group (C) which made up of 10 female white rats which were also weighed, but leaved without any treatment. Female rat’s pregnancy rate and the number of newborns were investigated. The results recorded a superiority of the group treated with propolis in pregnancy rate of 80 % compared to the control group, which gave a pregnancy rate of only 60%. It was also demonstrated that the effect of alcoholic propolis extract is beneficial in increasing that of offspring compared to the number of offspring in the control group (55 vis 29) respectively.
