Factors Affecting the Number of Fetuses in a White-tailed Deer Herd
Data were taken on 1,103 pregnant white-tailed deer (Odocoileus virginianus) harvested from the Savannah River Plant in South Carolina from 1965-1985 to describe temporal, age specific, and habitat effects on fetal number. Time periods were thought to represent periods of high and low population density. Age was the most significant factor in altering fetal number both with and without the data from the fawns included. Low fetal numbers per doe in 0.5- and 1.5-year-old deer and a high incidence of twinning in the older deer was responsible for this effect. Mean number of fetuses per doe...
