Very interesting topic. I thought about this subject when I looked at the White Angus cattle at the Iowa State Fair yesterday. They must not carry this defect, but I wonder how this breed has maintained itself over the years after decending from one white cow. Vert interesting genetics.
Are they Albino? Are they truly Angus? Tried to google them, to no avail.

I saw the white Angus cow, and calf at the fair too. Fascinated by them! White with blue eyes. They also had what looked like black eyeliner around their eyes. I would love to have one.

As the story goes, they were started in the 50s or 60s by a man who had a white cow that always had white calves when mated to Angus bulls. Her daughters did likewise, as have her decendants to this day. As you all know, black should be dominate, but in this case it isn't. It is said that they are not albino because they have blue eyes as opposed to the pink eyes of an albino. The herd has been passed on to the third owner since it was first started. There has always been just enough interest to keep the breed ( if it can be called that ) alive. The man who has the herd now is named Knutson. I find it very interesting.

For what it's worth, I have never had a white heifer that didn't breed.

I'm thinking this is a pretty rare condition.

I've never had a problem with a white shorty heifer breeding.

We have had many white heifers over the years and this has never been a problem but I do know of a couple of lines years ago that had the problem. According to vets I have talked to it is related to the white gene pased along in some cattle. I assume a genetic defect on the same chromosome. The problem is hymenal defects in these animals. We have several white females in our herd today and have used three different white bulls in the last ten years and have had no problems so I suggest if a perso was concerned have a look at the cow herd the heifer is from to make sure the white heifers are making productive cows.

this may be a dumb question, but why don't Charolais have problems with it?

As I understand it, Charolais cattle are not true white, they are black or red or whatever, with the presence of the diluter gene.

why don't they breed.....are they missing pieces, so to speak?  Or are the pieces that are there no functional?

British Whites are some of the most wound up linebred cattle on earth-like murry greys but they are about 150 years older as a breed and wound up from day one-they are Shorthorns and they dont have the White heifer deal-which I have only experienced twice-both out of White heifers that went back to AF Deerpark Dividend 932-Like the dwarfs I got and later saw out of a daughter of a KABA LEADERxFULL SIB TO KABA Rose. its like a computer virus-some of the Irish cattle were so inbred whaen they first got here-and then it got intensified -(most recently and similar with the Solution -Trump-on top-Trump-Kaba yata yatta on the bottom-THAT-there are genetic chinks in the armor -and wierd things start to happen, Im going to quote Edward Quane (DEERPARK) when I visited him at his home in Ireland in  1990- "Its come to an end -AND WE HAVE TO HAVE AN OUTCROSS" O0 O0

I bought and produce many whites on my short history as Shorthorn breeder.
Never had problems with whites.
Whites are my preferred color just with roans!
But, last month received a call from a friend that import with me some embryos from UK.
He got a good white heifer that is totally infertile!
She is free of american blood.
Also show some red ears and muzzle.
Possible a randomical character...some have lucky some not!
Look for a pic of heifer, but none in good position to show her marks.

Most are, but there are now some "pure" Angus that are white. The results of a single gene splice.

One strain used the leghorn chicken gene, but I guess that qualifies as "GMO". The next strain used the silver galloway gene. I'm not sure if either strain is still being developed for commercial use.

I had forgotten about them using the Short hair gene from Senepol cattle. It's crazy what a little gene editing in the lab can do these days.



So, in the end, we took the white coat from Silver Galloway and the short coat from Senepol cattle and we put both of those onto a champion Black Angus line.
