If im correct most genetic defects will trace back to inbreeding and possible linebreeding.
Robert- you're right. Inbreeding exposes the defects. I don't understand why semen distributors and/or breeders haven't been doing linebreeding tests, I hope now they will start. I've been digging up as much info as possible on this and have contacted the DVM studying this, Dr. Steffen. He said AM and this hydro is a genetic defect coming from 1680. Our operation has unfortunately become a statistic, the calf we had has been confirmed as a hydro calf. It was out of Dr. J Analyst, and the cow goes back to 1680.robert":y3plek0l said:Avalon":y3plek0l said:Nope its too much inbreeding and line breeding of these lines that created the problem. :cowboy:

You are incorrect, linebreeding / inbreeding didn't 'create' these defects, it exposed them, and none too soon! Imagine if, for example, that worthless sack of sh... 1680 had been bred to 35 of his own daughters, it would have EXPOSED the TWO defects that he was carrying, but that didn't happen, so that's the shape we're in today. Perhaps, in the future, a sire that has 1000 progeny registered to him has to be bred to 35 of his own daughters to determine whether the bull is carrying any deleterious recessive genes, before he goes on to sire 4, 8 or even 12,000 calves a YEAR!

Just because I used an AMC bull doesn't mean I'm chasing numbers. I breed for moderate sized, easy fleshing, maternal cows with stayability. Numbers do come into play though, especially when you're breeding bulls to sell.eric47847":2ld8uinp said:this is why i believe that we should just be breeding for functional, easy fleshing, phenotypical, milking, and easy going cattle. quit chasing these f-ing numbers and breed cattle for cattle. if you want to use a carrier bull, you should be able too, its just that you are going to be the person who suffers for doing so. this is my opinion
Jeanne - Simme Valley":3fesan9b said:No "true cattle BREEDER" (not a multiplier) should EVER even consider using a carrier bull. It's beyond me to even imaging people willing to propagate genetic defects. Sure, you can breed a carrier to a non-carrier and never have a problem.

I realize that you can use that carrier cow/bull and breed to a non-carrier and every calf can go into the feedlot. But, again, there will always be a slip here or there and they end up in someones herd.
Robert is soooo right. This should have been exposed MANY MANY years ago. Someone slipped up big time. Some of these big breeders HAD to have known there was a problem and just swept it away.
There is no way that "all of a sudden" these defective calves are NOW being reported left & right. There had to be many calves born in the PAST that were not getting reported.
It looks like AAA is finally stepping up to the plate. From what I have read, I think they are handling the curly calf syndrome properly - giving breeders time to "regroup". I haven't kept up on these other problems. Looks like a long road ahead of Angus (and Red Angus) breeders.
Here's a report I received from the American Simmental Assn.:
"The Red Angus Association working on controlling Osteopetrosis (OS): Often called Marble Bone Disease, OS has been known as a bovine genetic defect for decades. Recently, Red Angus has documented carriers among their popular sires. Dr. Jon Beever, at the University of IL and other scientists have helped them develop a DNA test for carriers.
SimGenetic pedigrees carry the influence of some of these Red Angus carrier sires, so please be sure to review the sires on their website (http://www.redangus.org, then Genetics, then defects, then review the carrier list). If you have one of these popular sires in your pedigrees, call Marilyn here at ASA Headquarters to get information on how to test your cattle for OS. AgriGenomics is the service provider (just like TH and PHA testing). This lab requires either semen or blood. "

Jeanne - Simme Valley":31b19bma said:Frankie, I did not make any comment about Gardner. Don't know them or anything about them. What did I "rant" about that is not true?
The fact that: using a carrier "can" keep the genetic defect around? Sooner or later that carrier gets sold or her/his offspring gets sold. Even if they just get shipped to the market, there's always the chance another "breeder" will purchase them.
You should be pushing for everyone to destroy all carriers - in a timely manner.
I'm sure there are flush cows out there that produced defective calves in several differant herds. That's not inconceivalbe - right? If you purchased embryos & had a defective calf born, wouldn't you contact the owner of the donor? How many calls would it take for the owner of the donor to get suspicious that it really wasn't weed poison or other environmental issues????
I don't know any of the "big breeders" and I don't need to (well, I do know some). As a PB breeder, I understand how genes are spread out all over our nation if "you have a good one" and you have money to promote him or her, there are LOTS of offspring in many, many herds. Word gets around. I can't believe someone - anyone - wasn't "suspicious" long ago.
As far as my breed. The ASA has been testing the top 50 used bulls for genetic defects for a number of years now. Here is their latest ruling:
• ASA Board Sets Policy to identify Suspects for Genetic Abnormalities:
Note: ASA reserves the right to request DNA testing when necessary.
Effective June 1, 2009, the following policy will be set in place to describe a suspect animal for genetic defects and testing policies to identify carriers of genetic defects that have DNA tests available.
A. Identifiing Specific Animals
Any animal with a documented carrier in the pedigree, unless the intermediary ancestors are tested-free or designated pedigree-free.
Any sire or embryo donor dam with 1/8 blood or more of the defective- gene source (breed, line, herd), unless the intermediary ancestors are tested- free or pedigree-free.
B. Reccomendations for recurring testing:
50 most-used sires (managed and paid by ASA).
All suspect A.I. sires
All suspect natural sires
All progeny of suspect sires, if the suspect sire DNA is unavailable for
All suspect donor dams.
C. Managing these policies
Genetic abnormality designations will be real-time. Test completions (DNA determination of carrier or free) will affect animals in downstream pedigrees.
Progeny (of untested suspect sires or suspect donor dams) that has performance data submitted or request to be registered requires compliance (DNA testing) to satisfy B2, B3, B4, or B5.
I think our breed has acknowledged the possibility of defects getting into our breed through crossbreeding & upgrading, and has taken a very strong stand for many years now.
I would think a reputable breeder like yourself would be thrilled with AAA setting strict rules. As a breeder, I tried to put myself in your shoes and read their rules. I thought they were very "do-able".
I'm sure there are flush cows out there that produced defective calves in several differant herds.
I can't believe someone - anyone - wasn't "suspicious" long ago.
If Gardner had problems WITHIN their herd "for years" - they were having problems with customers' herds - common sense.Since the breeder of the most responsible bull has been working with their vet and KS State to find the problem for years

Jeanne - Simme Valley":2i2wba1y said:So, Frankie, are you related to the Gardners? You sure seem to be "guarding" their reputation. Again, I will say, I was not referring to the Gardners.
And, again, I will say "someone" "somewhere" knew there was a problem. I don't have to KNOW any details. Just common sense.

And, again, I will say - if someone was a top breeder - selling genetics all over the USA - it is hard for me to believe they did not get calls from CUSTOMERS having dead or deformed calves. And, again, I will say you can not blame them on poisonous plants or environment. If a vet was given the facts, it shouldn't be too difficult to put 2 and 2 together and decide there was a genetic defect.
I understand it is YOUR breed having these problems, and it is difficult for everyone. Hope you don't have any carriers.

Jeanne - Simme Valley":c1nii09n said:Frankie - well I'm dissappointed in YOU. If you would quit being so defensive about Gardner's and just listen. I am NOT complaining, pointing fingers or anything else about the the Gardner's. I don't know them & I don't care about them.
I think K-State is one of the BEST vet schools in the nation. My husband went there. We used to live in Kansas. :banana:
My comment is about ALL breeders that sell nation-wide. Just think about this. If you owned a bull and you were selling semen - or you owned a flush cow & were selling embryos, wouldn't you be getting concerned something was genetic if you received phone calls from multiple people that had your genetics and was reporting to you that they had a defective calf???? My point about the poisonous plants, is that you couldn't discount a possible genetic defect if calves were being born in different parts of the country. It is different if you personnally were having a few calves born over a number of years with a defect and your vet said it must be something environmentally wrong.
And by the way, yes, I had a few dead calves this year to an unknown problem - and yes, the vet put the 3rd one down and it went to Cornell for testing. It was Listeria. Ended up saving 5 that were affected.
eric47847":2cxoyjs7 said:Every animal in this world has a genetic defect that they are born with, its just nature.
Yes, I had SICK dieing calves with no symptoms - no diarhea, no respiratory, no nasal discharge, just got weak on hind quarters & ended up going down. Cornell had a "reasonable" answer, since they cultured Listeria in their brains. I didn't have deformed calves at birth - if I did, and they did have a parentage "link", I "think" I would be a bit suspicious. Seems reasonable that we are talking a different subject.You had dead calves? Why do you think Cornell was right? Perhaps they overlooked some sort of new disease? You know, like Kansas State did for Gardiners?
