SUMMARY: Ecological research of roe deer population was conducted in
the forests of Baranja in the period between 1968 and 1972. One research project
from that time had the aim to determine fertility of the roe deer population
in the Haljevo forest. Usual mating season of roe deer started in the second
half of July and ended around the middle of August. Embryo of the impregnated
roe deer cannot be seen by the naked eye till the end of December because
of temporary standstill in the development of embryo diapause during the
period of inactivity, i.e. because of imperceptible cell division in embryo. Because
of that, gravidity of roe deer after mating season (July-August) till January
was determined by examination of the ovaries of shot roe deer, i.e. by identifying
corpora lutea on ovaries or its cross-section. Extraction of ovaries from
the uterus of shot roe deer was done during the process of regular kills, from
October till the end of January, and during the process of sanitary kills till the
beginning of April. Parts of the uterus with ovaries or embryos were extracted
on field from every shot female roe deer and put into glass containers with 4 %
formalin. The collected material underwent a detail laboratory analysis in the
following days and the number of corpora lutea from the left and right apex of
the uterus was recorded for every female roe deer.


Establishment of roe deer fertility after bringing forth a fawn was conducted
from the beginning of May till July 15, twice a week, and after July 15 once
