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!
