Freeze a bull's semen and a champion sire can father calves for decades. VanDemark reports the science that made it possible: selecting semen, choosing extenders, dilution rates, the role of glycerol, and the freezing rate that keeps cells alive. A clear technical record from the dawn of artificial breeding. For the serious cattle breeder.

Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
