My name is Eric Danzeisen.  I breed cows everyday in the Central Valley of California.  I live in Tulare county the heart of the US dairy industry.  I’ve worked for a major A.I. stud for about 8 years until I realized I really needed to start a new A.I. company, Sierra Desert Breeders, Inc.  So I just did it one day with a little planning from my partner Wout Vander Goot.  We started with 6 bulls in 2007 and now have well over 50 bulls producing semen for customers all over the world!  I truly am living my dream with my wife and kids!  As you follow along my blog you will see many things.  Some which include: bull profiles, reproduction ideas and advancements, news from Sierra Desert Breeders, personal stories, personal genetic theories, and always trying to beat up on the big A.I. studs!
