I went back and read the article in the Shorthorn Country. It claimed they had only tested 11 head. I know how many I've tested, which means there can't be many breeders testing for it in the states or they're not using the ASA to do the testing.

I assume I have a couple carrier cows in my herd based on a calf each has thrown and one calf I know was carrying, so all future herd bulls will have to be tested clean here. It's not an option, and any breeder wanting to sell me a bull will need to show me some results or I'll move on. The defect won't get the chance to cost me any more money. I purchased these cows, which leads me back to that 11 head tested number being even more interesting. On the other side, I recently sold a bull and out of the blue mentioned he had tested clean and the breeder obviously knew what I was talking about.

You can track one of the sources of the gene back over 50 years. When you speak with the right circle of old breeders who knew the source, it doesn't seem to have been a secret even back then. If you mention having semen on a son the response is, "ya, don't line breed to him". Some of the bulls between then and now sired relatively very few calves, but obviously it managed to hang in there until today. It appears to me Shorthorn breeders went after muscling, and they found it.

The past really doesn't matter to me as we have a test to move forward with, but if you connect the dots and read between a line or two I can't help but wonder if the source I tracked to is the same source north of the border that was used under a different name.

Do the AI companies test for all of this? I have brought in numerous sires to South Africa from Semex over the last 15-20 years! None are listed for TH or PHA but one is a probable DS and they all have no tests listed for Myostatin. I am getting nervous here!
Are they obliged to have the bulls tested?

Is this all going to come down to validating MarkTs  G9 theory?  O0

I only have 3 straws on G-9-But a bunch of 2975-I dont know about Myostain-At least the BWS didnt get too crazy till the Mark 4s got mixed with Enticer-Along with growth patterns that sometines didnt make sense. However-Before TH was an issue or even known about- we used RFC Magnum-A CF Fortune out of  a picture Perfect going back to Mark 4. Lawrence had never seen nightmare trainwrecks like that. So I asked him what do the cows go back to?-Answer MARK 4. That leads me to believe with 20 plus years hindsight that  Mark 4 was TH  because the lethal  occurrences were so numerous. Id like to bust a straw of 2975-If I had the Mark 4 semen which I dont-Im wondering if 2975 would even have been Mark 4s sire in the first place-According to a number of people who would know-G-9 was thought to be a Cunia son or grandson.Which would be great with me. Im just not sure if other than maybe Hallmark how many direct sons or daughters of mark 4 or even G-9 were available in Canada O0

When there were 11 tested, 3 were mine and fortunately all clean.

Buster 14k was mentioned and so was Ramrod.  What is the suspected starting point in Canada?  Or at least in your heard?

I have heard Buster's sire, Eionmor Ideal 69F was a carrier. If so, it's likely further back than that. He does have a common sire on both sides of the pedigree, but it could have come from any ancestor.

Seems like when we go with an animal that is more extreme........or a tad bit different looking.......sometimes it's because of a mutation.

I have always been told that his maternal grand sire GAFA Mochican was the starting point. About 3-4 years ago I contacted the American Shorthorn Association about listing myostatin as a genetic defect. I still have the email, but basically the board stated that it WOULD NOT be listing it as a defect, but would provide testing for anyone that wanted it. I have had several tested over the past 3 years and I believe that you can tell by looking at the calf if they are carriers. They usually are more descript in their muscle shape, and are slightly finer boned.

We showed in Louisville the year G-9 was shown as a 2 year old.  We were told by the present owner that he was assured by the breeder that he was not a Maine cross.  The rumor that we heard at that time was that he was sired by Capone.  I have semen from Capone, Cunia, G-9, 2975 and Ransom 179.  I'll bet something could be figured out with present testing methods, as if it will make a difference today.  I seem to remember that in the old literature, Dollar II was mentioned as a possible carrier of double muscling.  I used him back when it first became legal and really liked the results.  He crossed really well on my Ultimate Type daughters.  There's the potential for so much outside breeding in the backgrounds of most every breed.  Finding a single culprit like Improver for TH could be an exercise in futility.  Ayatollah was widely used in Canada.  Maybe he's the bad guy for Myostatin.

So your contention is that it goes back to Ideal 69F's dam? Has anyone ever tested Gafa Mochican? I have to admit Mochican sure looks like a carrier..... I was told he was extremely heavily muscled and really orange in color. I have no idea and I'm not on a witch hunt.   I will say that I asked Dr. Bert Moore about this years ago and he thought I was on the right track.

I'm with X-bar on this one. I think its not much of an issue. They jumped the gun on DS and have decided to play a wait and see game on myo. I would be suprised if 5% of the current breeders in the states even knew what it was.

Mohican sure reminds me of Strathore Irish Magic-There is one common thread between these two and the bulls X Bar listed-The superflag blood-Hey Medium Rare do you think I might be on the right track-he did make them bigger and "variations there of" were used alot in that respect. O0
