To help you with your breed selection process, this article about picking the right cattle breedshould help you get started in narrowing down the list and evaluating if Low Line Cattle suit your goals. It will prompt you to identify exactly what you expect from your cattle, which in turn will help you ask the right questions when you start approaching breed associations or individual breeders.
Best of luck with your project - it sounds like a beautiful place!
My name is Corrie. I currently live in NW Montana, but have been dreaming about re-locating to central coastal CA for a few years now (I want to grow avocados!). I visited Paso Robles (my preferred area) and looked at a few properties last year. I was ready to go after seeing some parcels at the top of the coastal range there between Cambria and Paso Robles. Unfortunately, my property here is not selling, and I'm stuck.
Anyway, the point is, I would love to connect with like-minded people in that area. I wrote to Joe Morris, of Morris Grass Fed, who has a ranch in that area, asking him lots of questions about how to raise animals on grass there. He was very generous with his time in responding to me. I'd be happy to forward that e-mail to you, if you'd like. Please contact me! Thanks!
