I wondered if it might be cool to have a list of triple clean AI bulls listed here. It would just save a lot of research for everybody. TH,PHA, and DS clean.

Could you add Myostatin mutation to that list?
A list with TH, PHA, DS and Myostatin would be even more useful.

Myostatin.  Ive never even heard that term used outside of a small sect of shorthorn breeders in Canada.  As far as i know, the ASA doesn’t even recognize it in the their AI sire testing requirements.

Hot Commodity shows to be be th free and pha free. What is his ds situation. I'm not sure that the ds deal is a big deal anyway.

Hot Commodity is triple clean.

All active AI sires are required to have testing on file in the database. The list of triple clean bulls is very long with something for just about everyone to chose from.

I always wondered if there was a son of Gismo or JPJ....that sired like their sires......only they were triple clean. Really the ds deal is minor....minor......in the grand scheme of things. If it wasn't for the pha deal it wouldn't have even been analized.

The ds thing ins't a big deal.....unless you've had it.  2 of the first 3 calves sired by my Proud Jazz son were deformed, 1 seriously.  The bull was immediately hauled to the sale barn.  Talk about losing money on an investment!  The two "misfits" were out of my friend's cows and I don't know what their breeding was.  And I don't care.  The only thing that matters to me is that he had 2 throwaway calves.  I will not use a bull any more unless he's triple clean.  It's amazing to me that I can still look at recent sale catalogs and see a sale where only 1 heifer of the entire offering is even clean by pedigree.  All the rest of them are potential carriers of at least 1 defect.  None of them have been tested according to the ASA website. I don't want to start this debate, there's been more than enough on SP about it.  All I know is what I am doing.

I had a mildly ds affected calf. Was out of my only pha carrier cow. I'm just saying that I have heard that in order for a ds affected calf to show symptoms......is that they have to be out of a pha positive carrier cow. There are not a lot of pha carrier cows out in the nations commercial cowherds. But now that it has been exposed.......you kinda have to deal with it.

Myostatin is the enemy of IMF/marbling, and I would think it would be advantageous in a grading system to know which cattle carry the myostatin mutation. There are several different mutations, some of which produce more muscle than others. It is possible not to know a single myostatin mutation carrier animal as it could appear much the same as a normal animal with a little more muscle than normal. Going by the myostatin mutations appearing in the SH breed in the UK and Ireland I would say their ancestry would suggest there are myostatin mutation carriers in both the Canadian and USA population of SH.

There are.

People just aren't talking about it.

What companies test for it......I wonder out loud.

You can test for it just like the other three defects through the ASA. You just have to check the box on the far right and write in Myostatin on the form. I believe they charged me $27 on the last one I ran.

It’s commonly talked about and tested for in the Western Cananadian Shorthorn world. Other breeds don’t seem as keen on bringing it up. I think the jury is still out on the significance of it - as different mutations have broadly different effects. More research would certainly help. In the meantime, testing and informed choice don’t seem like a bad way to go imo.

In the '60's at a university herd there were double muscled cattle calves born to of one of those 2 breeds (the one that used to have no "known" defects....).  Double muscling is not functional or practical at all in its pure, homozygous form, but some have suggested using a double muscling breed as the terminal sire for improving yield grade and avoiding waste.  Having quality (marbling) is important in freezer beef, so myostatin gene is something we will avoid.

What about Angus and Herford cattle? Do they have a myostatin thing going on?

Angus does. Galloway as well. It seems most breeds have a myostatin defect of some variety. They’re relatively recent mutations (150-300 years) that have inadvertently been selected for by breeders (probably for increased muscling).

I think that the Angus variation......nt821.........is the same as the Belgium Blue deal. Interesting...............what is the Shorthorn variation....I wonder out loud.
