Breeding Mink For Their Fur Classic Reprint PDF Download

Excerpt from The Breeding of Fur Animals The usefulness Of breeding data 111 this situation may be illustrated by the case of the marten (fig. At its experiment station near Saratoga Springs, N. Y., established in 1923, the Bureau has been studying the breeding and the gestation period of the marten. As a result it has found that a period Of 9% months elapses between the time of copulation and birth. With so long a period Of gestation, many pregnant females are bound to be destroyed under the prevailing system of open and close seasons. It is obvious that unless the trapping season for a fur animal corresponds accurately with its gestation-free period, the close season will not accomplish what it is intended to: the prospective generation will be destroyed along with the one trapped. Even this precaution, however, would be ineffective in the case of the marten or the fisher, for their gestation periods are too long. A 5 or 10-year closed period is necessary to prevent local or even general extermination Of these two fur animals.
