Some observations on the dilution, cooling and freezing of canine semen

Abstract

ABSTRACT Canine semen was obtained by digital manipulation from two donor dogs and twelve stud dogs. The sperm‐rich fraction was diluted with either of two different diluents and the survival of spermatozoa before and after freezing was determined. It appeared that there was no difference in the post‐thaw survival rate in either of the diluents used.
