Also, you may want to speak with Guy Gould, manager. Maurice is 93 and his memory is starting to fail him. Progress in a conversation is challenging at times. I really wish I could have spent a day visiting with him in his prime. His mentor, Dr. Jay Lush, was a top geneticist that taught Maurice how to build the foundation of a linebreeding program. He instructed him to "test" his herd sire prospects by breeding them to at least 14 of their daughters. If any one calf came out with a defect or was really sub-standard, they culled the bull and all females and tried another. You can imagine how long it took him to get 3 "Pure" sire lines to start his linebreeding with before he closed the herd.
The cattle are fed well, it's not like they are PCC genetics that live on pasture year round - oh wait, those can't either.
After my visits with Maurice and Guy, I bought Jay Lush's book through Amazon. I am using it as a guide, along with my conversations with Jim Lents and his book. Combined with my own observations of what cattle work here and which do not, I'm a few years into a linebred herd of Galloways. I am a few years away from closing the herd, as I am still looking for sires. I'm just sharing this to illustrate how much work goes into a program like the Irish Blacks. Regardless of rumors and claims, even if they come close to doing what he says they can, they are far better than most AI Alumni, Show Ring Sweeties or Test Station Tubs.
