UNIVERSAL MEDIUM AND METHOD FOR EXTENDING THE USEFUL LIFE OF SEMEN IN VITRO

摘要

A universal medium for extending the useful life of semen, in vitro, is provided comprising, in effective amounts, egg yolk, alpha -aminopropionic acid, and glycine. If the semen is to be stored for long periods of time at reduced temperature it is preferred that glycerol and an ionizable salt, such as sodium chloride, be utilized in the medium. The medium has general utility for extending the life of semen from all types of mammals and birds and is especially valuable for extending the useful life of sensitive types of semen, such as turkey semen. Such sensitive types of semen can now be kept viable until they can be frozen. The invention provides for storage by freezing of types of semen which have not before been successfully frozen.
