Preservation of Bull Semen at Sub-Zero Temperatures

Preservation of Bull Semen at Sub-Zero Temperatures, written by N. L. VanDemark in the late 1950s, is a scientific publication focused on the techniques for freezing bull semen to maintain its viability for artificial insemination. The book details experiments on factors like semen selection, diluents, glycerol concentrations, and freezing rates that influence sperm survival post-thawing. It serves as a comprehensive guide for researchers and practitioners in animal science and veterinary medicine, outlining practical steps for the collection, dilution, freezing, and thawing of bull semen.
