Fertility Control in White-Tailed Deer by Steroid Implants
Matschke GH. 1977. Fertility Control in White-Tailed Deer by Steroid Implants. The Journal of Wildlife Management. 41(4):731-735
Estrogen (DES), progestin (DRC-6246), or placebo tube-type Silastic® implants were placed subcutaneously in female white-tailed deer (Odocoileus virginianus) before the breeding season. No treated deer were pregnant after the breeding season. The daily release rates averaged 193 μg (estrogen) and 93 μg (progestin). The progestin-treated ovaries were characterized by large cystic Graafian follicles; the estrogen-treated ovaries were small and externally smooth but small Graafian follicles were present internally. Graafian and growing follicle cell counts were not significantly different (P > 0.05) among the 2 treatments and control.
