Total gonadotrophic potency of mule deer pituitaries.

Abstract

ACOOPERATIVE, study of reproductive phenomena in mule deer at the National Bison Range, Moiese, Montana was initiated in the fall, 1953 by the Department of Zoology, Montana State University and the Montana Wildlife Research Unit cooperating with the U. S. Fish and Wildlife Service and the Montana Fish and Game Department. A deer herd reduction program was to be instituted on the National Bison Range for management purposes. In order to take advantage of this material prompt action was necessary. It was agreed that part of the reduction program could be spread over a period of one year in order that autopsy material could be collected every month of the year by us. The principal objective of the present investigation is to report on the total gonadotrophic potency of entire pituitaries of female mule deer (Odocoileus hemionus hemionus) collected from three different age groups throughout the year. Reproductive tracts, endocrine glands, and other tissues were also collected. The analysis of material in the...
