So is there a test developed then....since free cattle are listed? I think rcn canyon chief 092 120186 is an interesting pedigree to look at. Where oh where do we go?

 

[aj]

YES! My Lancer 442 appears to be clean. Also cherokee canyon....yippie ki ayee!

For those of us that don't see red only black or roan, what is marble bone?

 

[aj]

Genetic defect that crossed over from black angus to red angus through Stormalong. Hit DL's bue web deal for pictures.

Aj, Dr.B HAS NOT made a connection to the black angus breed at all. In theory it would make sense, but so far NO link.

The Red Ang Assoc has handled this defect with terrific professionalism and jumped right on top of it.... something that the black angus assoc hasn't not seemed to master yet.
Doesn't it suck when a younger sibling shows up big brother!!!!  Go Reds!

VJ - beware the blacks are not immune, in fact there are a number of documented MB carriers in the Angus breed.

MB is osteopetrosis - turns out there is a deletion in the gene that is involved in bone formation - calves are born 10 to 30 days early, have abnormally shaped heads, brittle bones and no bone marrow. There are pictures and a more detailed description on the RA web site. It is another autosomal recessive disorder, like TH, PHA, AM etc 

It is believed that Stormalong (a RA bull out of black parents) was the founder of MB in the RA breed - he is in almost every RA pedigree - all documented black MB carriers with full pedigrees can be traced to a 1900 black Angus bull, as can the 4 recently identified by progeny RA MB carriers (Romo, Romeo, Lonk Canyon 509R, BC Major R057)

But like Show Heifer said the current information and testing is for RA only - would make sense but not all things that make sense are reality

Good job RAAA - got my RA bull lined up for my heifers and you can believe that he is MB free  ;D

Dr. aj has formulated a geometric formula tied to moon revolutions around Saturn that tends to point to a well hypothethised jump to unanimous conclusions of cowboy logic that cannot be held in contempt an is above challenge from all amatuer archeologist or(and I repeat or) sunday school teachers.Do I stand corrected? It depends on your definition of "stand corrected". I didn't see Mulberry listed one way or another. Hummm? Could it be a Canadian conspiracy?

My black is club calves or Maines. Never owned an Angus except what's in the Maines and club calf genetics. I do have a red NFL out of a Windsor dam that is a spitting image of a Red Angus. She has the dark muzzle like many RA cattle Thanks for the info, DL

Agree cowboy logic cannot be outdone by sunday school teachor rhetoric

Much to the chagrin of many NONE of the bulls in the Brylor semen catalog except for the carrier UBAR GRAND PRIX 102 have apparently been tested - despite encouragement to send semen to Dr B from some down north

Is the testing facility on line to accept sample from anyone yet? Has it been approved or whatever? I assume Durham Reds could be tested although they might only be one half Red Angus? Is it a purple tube top situation? And what is the current price for gold per ounce?

Life with the gene gang is a purple tube top affair (in most instances) but the test  is not yet commercially available - should be in 30 to 45 day. Like with TH, PHA and AM the thought was to test the bulk of the AI sires before the breeding season....you can tell Dr B has cattle

Thanks for the update.DL

It is interesting to me the Bkt strm 751626 (8605) bull is listed as carrier. He was born in 1964. He was a grandson the old stormalong bull. It is fascinating to me that this deal didn't run any deeper in the breed than it did. Could the Becton(forbes) or who ever got a handle on the problem in the 60's or whenever and quit using a problem line? I have heard that Becton does random line breeding in herd of 1,000 cows or whatever it is. There must have been semen on 8605 and they did a test from that?cool! Those original 5 Red Angus breeders or what ever it was is a fasinating bunch to study.

aj - we did find semen on the Stormalong son as well as a necropsy report of a MB calf...it was a big help...goes to show the importance of reporting abnormalities to the stud..
