Our research examined the time of conception of fallow deer in the DALERD South Plains Forestry Private Limited Company's Gyulai Forestry Area. We collected data from pregnant females who had been shot in the hunting season. At the time of evisceration the uterus was removed and dissected; and sex and body weight of embryos were recorded. We were able to collect and analyze 149 samples for our study. Based on the sex and body weight of embryos, we calculated the fertilization date for each animal within our sample group. There were no significant statistical differences found between mean fertilization dates of adult does and yearlings (t = -0.72, p = 0.47). The mean fertilization date of does (with a gestation period of 231.5 days) was October 25th (SD = 13.82, n = 120); whereas, for yearlings this date was October 24th (SD = 12.97; n = 29). Based on embryonic development, results showed that in the population we examined, 2 % of females were impregnated in December, 1.3 % in September (at the end of September), 24.2 % in November and the majority, 72.5 % were fertilized in October.
