Title:  Estrous cycles in captive whitetailed deer in South Carolina: a preliminary report
Author(s): Hamilton, R. J., M. L. Tobin, and W. G. Moore
Year: 1982
Abstract: Since the spring of 1979, 42 white-tailed deer (Odocoileus virginianus) were obtained as fawns and were hand-reared for use in reproductive and genetic studies at the Rembert C. Dennis Wildlife Center, Bonneau, South carolina. Bucks and does were maintained in separate pens, but were paired daily during the 1980-81 and 1981-82 breeding seasons. Estrus cycles were determined in 11 instances involving six yearling (1 1/2 year) does and one adult (2 1/2 year) doe. Intervals between breeding dates ranged from 23-32 days and averaged 24.7. Case histories of several abnormal situations were discussed. In one, a yearling doe conceived on January 4, 1981, during her fourth estrus cycle and bred 26 other times on 22 days from January 22 through April 16, 198 1. Other observations discussed included: average and extreme conception and parturition dates, duration of receptivity, litter size, sex ratios, and behavior associated with breeding activity.
