Fecundity, losses and real gain in roe deer population

Abstract

The research on fecundity, losses of calves and real gain of roe deer was carried out in the hunting ground of "Barajevska reka". The losses were found in 60 calves, fecundity in 29 does, and real gain of roe deer was monitored during three years in three different hunting reserves. The losses of calves account for 24.59% of total roe deer losses and are the result of the activity of biotic and abiotic environmental factors, as well as the influence of anthropogenic factors. Average potential roe deer fecundity in this sample was 1.54 embryos per gravid doe. Real gain of roe deer varied depending on the year and hunting reserve and ranged from 0.65 to 1.11 calves per gravid doe. The greatest influence on the real gain had, apart from the year, type of management in the hunting reserve. Proceeding from the abovementioned, hunting of roe deer in one hunting ground must be performed within hunting reserves, in accordance with the real gain within them.

Istraživanja plodnosti, gubitaka lanadi i realnog prirasta srna sprovedena su u lovištu "Barajevska reka". Gubici lanadi čine 24,59% ukupnih gubitka srna, i nastaju usled dejstva biotičkih i abiotičkih faktora sredine, kao i pod uticajem antropogenog faktora. Prosečna potencijalna plodnost srna u ovom uzorku bila je 1,54 embriona po gravidnoj srni. Realni prirast srna varirao je u zavisnosti od godine i lovnog revira u rasponu od 0,65 do 1,11 lanadi po jednoj polno zreloj srni.
