    Myostatin gene

    I was mistaken about cattle normally having a majority of slow twitch muscle fibers. Only two mammalian species, thus far, have been found to have predominantly slow twitch muscle. Humans and the slow loris. https://www.inverse.com/article/33452-chimpanzee-super-strength-endurance-muscles-human

    Myostatin gene

    I have been reading a lot about Myostatin. When Myostatin is inhibited from regulating muscle growth, not only the number of muscle fibers continue to increase, but the type of muscle fibers that increase are the type II fast twitch fibers. Normally the muscle fibers in cattle are predominantly...

    1930 Iowa Exp. Station report on Shorthorn Galloway crosses

    Boreal, if you have pics, I'd love to see your results. Are you using a White bull? There was a very disappointing mess up down here this fall where a couple Blue Grey calves out of the Whitebred bull Taliesin and a good black Galloway cow went to the sale barn. If anybody in Wyoming bought...

    DMH Mr T is the Resource son. His calves looked good. Now that I see Resource, I may do a half sib mating from Mr T. Its neat that you saw the Weston herd for yourself.

    I confess the way this calf is gaining condition is blowing my mind. I'm so happy I was able to get ahold of him before he was put on a "development ration". Whatever he grows into will be breeding, not feeding.

    Thanks! I could not be more pleased  to find out what Weston Resource looked like and on pasture to boot!

    1930 Iowa Exp. Station report on Shorthorn Galloway crosses

    No... Mark posted them as a modern example. Looks like a picture from the UK by that stone wall in the background. I never got a real blue grey coloration with the white Shorthorn I had before. All my F1's were charcoal colored with white underlines.  I have an idea one might get farther with a...

    The white bull they were using in the 1930 research. Wish the 1930 Galloway cows and the 1 bulls were pictured

    1930 Iowa Exp. Station report on Shorthorn Galloway crosses

    These researchers were working on color inheritance. We think we understand the inheritance of roan much better almost 100 years later, but what about their information that Whitehall Sultan and two of his white sons threw red calves from red cows? The photo of the 3/4 Shorthorn steer is...

    The black cow with white underline is an Amos daughter out of a Galloway cow. She is a terrific F1 cow that raises better calves that my straight Galloway cows from the same cow family. As a calf, Amos was far more like the Felix calf than the Snowball calf. This is what I believe is the real...

    "Leader 6th son by a Maid of Promise 189th daughte" I'm supposed to say OUT OF about cows, not BY. Sorry about that.

    The white calf was born breech. I don't know about Felix, but I am very curious about the shape of the calves he will sire. This is a reservation I have and why I say he has a long way to go to prove himself. Try to remember that I am a producer of grass fed beef. I don't have great grass and...

    maybe. I'll remember you want him when the time comes. He still has a long way to go to prove himself.

    DMH Cattle Company. Scroll down to Minnesota on this Heritage Shorthorn Society Breeders page. Their program is essentially crossing old Heritage beef sires from the pool of semen Roy Lovaas assembled on Native Shorthorn cows. Then they use the sons and daughters from those matings in different...

    Heritage/Native Shorthorn Bull Listing

    These calves have been here a week. I'm sure the feed was much better at DMH. This is late cut prairie hay and the roan bull has definitely gained weight since coming here. They get all they want of this hay and mineral. The white bull has lost weight, or at least lost gut. Very fascinating how...
