Sires for Cattle on 4B

We started our herd in 2006 with a single bull, 4U2 Sparky Generator and he sired many calves for us.  He was sold in 2009 and we started using artificial insemination (AI) to diversify the herd. 


The American Murray Grey Association (AMGA) has a world wide registry of Murray Grey cattle.  This registry assures that the bull semen we use is purebred Murray Grey.  AI allows us to choose bulls with excellent carcass traits, specifically, genes for marbling and tenderness.  Through the Murray Grey registry we can find bulls that give smaller calves for our heifers and good temperaments.

We have used championship bulls from Australia and the United States.  Diversifying the herd has been fun and exciting to watch.  Below we have listed the AI, breeding, and herd sires we have used the last 5 years (excluding 2017 because we sold our calves that year).
