Genetic defects

[aj]

If I understand it right........there are 10 registered Angus dna tested as dwarf carriers. So there is apparently a test for that. I wondered about Herfords? Would the same test work on Herfords? Or do they do a different gene test or do they even test. I always thought that there would still be some dwarfism genes floating around. And then I always wondered if th or pha might show up in a Herford or Angus or Simmental on down the line because of unscrupulous breeding matings. Any thoughts?

And then I wondered about say the marbling gene or whatever. Would a test that works for the Angus breed.......work on a Shorthorn?

Thanks, A.J.  For which type of dwarfism is it?  Long nose dwarf? 

 

[aj]

I'm not sure....I'd have to check back. Seems like 8 out of ten animals listed on the AAA website had the same prefix and a lot of them were tested in 2011 maybe...

My understanding is the marbleing tests for the Wagyu breed, do not work with other breeds. I also doubt that marbleing in a one gene trait.

Thanks chev

As I understand it the Herford cattle have a few "diluter" gene carriers. When bred to Angus......you can get grey calves. I wonder if this is a bleed over.......from Simmental accidentally being introduced to the Herford breed?

There is apparently a hand full of curly calf carriers in the Simmental breed (probably brought in through the appendix program via Angus). Is the curly calf deal ever tested in say the Shorthorn breed? There has been a hand full of Angus used on Shorthorn cattle.

I guess BR New Design is a dd carrier. I think he was pretty popular.

tests make using carriers ok.


use the tests.


for instance, I have a few units of draft pick.


i'm going to use him on something i want more yield grade out of.


maybe sex select the semen since i have enough of it.

cool

i might do it on a sooner ali i have.


i had a draft pick son before. phenomenal calf.

I'd like to see a pic of that cow  (thumbsup)

Accidentally was the best world to explain!
Too many accidents on Herefords, Angus......on Shorthorn too, but are official accidents!

I googled around trying to find out if bison have genetic defects. I did hear one rumor of a condition malformed rear legs on bison thought to be genetic. Could it be that Deerpark Improver was used in a beefalo program........?? Naw.....it can't be.

everything has defects.  no need to bad mouth anything.

Interesting. I know years back I sent in a bull's sample for th. It came back clean but a little different. The bull sired a th calf. My bull.......was a twin......and I guess this somehow goofed up the th test somehow.

I have noticed in some of the dairy pedigrees that there are animals that show up as carriers even if both parents have been tested and are free.

It may be that for the most part the test may show that an animal is not a carrier, but as with anything if everything happens to align just right an animal can show up as a carrier.

Nothing is 100%
