Because there are more cattle that go back to the source cattle for MD than MSUD? Not from my understanding but I could be wrong. The one good thing about MD is that they quickly and clearly ID'd the source of the mutation and advised testing accordingly. MSUD on the other hand hasn't had the original animal clearly ID'd (to my knowledge) and some people only know it's in their herd when they have an animal that comes back MSUDC. If you have an ancestor test as MSUDC the AHA will not notify owners of progeny that they should be testing their calves. The online report in MyHerd can search for potential carriers in the background of your herd if you are Whole Herd TPR but not if you are a pedigree member. Not really a debate, there are more Hometowns and Homegrowns than most anything else. The sources for MSUD (at least the most relevant sources) aren't hard to figure out, they just have significantly less progeny. |

It's something I've been working on for 18 months. If you wish to send it to me directly feel free. |

In MD we have two bulls that were HIGHLY used via AI throughout the breed. |

I can tell you the pedigrees I'm watching with MSUD are free from 3008. |

The source is not nearly as important as the main spreaders of the defect. In MD we have two bulls that were HIGHLY used via AI throughout the breed. The popular sire effect (AKA Popular Sire Syndrome) is very dangerous when these type of defects happen due to the wide spread impact they have. However, I am not a fan of limiting the use of any bull. Let the semen buyers make the selections that work for them in their program. en.wikipedia.org/wiki/Popular_sire_effect#:~:text=The%20popular%20sire%20effect%20(or,genes%20necessary%20to%20produce%20champions. |
