THE EFFECT OF OXYGEN AND TYPE OF CONTAINER ON THE RETENTION OF THE FERTILIZING CAPACITY OF FOWL SPERMATOZOA STORED IN VITRO

Abstract

Summary. The fertilizing capacity of fowl spermatozoa, kept up to 17 hr at 10°C, was enhanced by storage in an atmosphere of oxygen. The effective degree of oxygenation of the semen with respect to the survival of spermatozoa in containers of different sizes has been considered and discussed. The fertilizing capacity of semen did not appear to be affected by a rapid fall in temperature during its collection.
