White Angus

They are still moving along on this.

This is the first time I've noticed they used show ring genetics in this project.

If they could have collaborated with the West Texas Alpha x Gamma calf project they could have caught even more attention.

Maybe white Shorthorns will be in great demand someday to cross on White Angus.

Why wait to correct this heat difference when we have proven breeds that can take care of this very expensive problem right now ....Veterinary told me about a test in feedlot measuring the heat off  of black cattle , used some kind of ultra violet light to measure it .... He said they were measuring up to  15 degrees between dark cattle and light colored X cattle , said the red cattle had an advantage of half that ...The hot summer month's affect cattle whether in feedlot or in the pasture bulls trying to breed cow's ... With bull sale time approaching this is a factor to look at ...My opinion is this might be a reason for so many injured bulls during breeding season an the tremendous amount of credit given at the next year's sale for replacement ...I have raised bulls of the dark breed's and light colored breed's and replacement cost's are definitely higher in darker colored breed's ..!!

All this effort for a breed already in existence? They are basically recreating a Murray grey...

OK...so the new fashion will to be the white cattle!
Go Charolais, Chianinas, Romagnolas, Marchiggianas.....

Agree.....white Aberdeen means as a light Murray Grey.
By the way, Murray Grey now has not show your 100 years history with her Shorthorn blood percentage.
Market is the final word!
Aberdeen sells better than Shorthorn, so, will take the party's the poor cousin!

I never understood why its not mentioned that the diluter gene Murray Greys must have come from...what? Not Shorthorn.

Crazy.  There have been some articles in the last year or so about the UofFL 'white Angus' herd... which derived from predominantly Angus crossbred cattle with some Chianina, Brahman, and probably Charolais back behind them several generations back.

I sent librarian a photo of one of a couple of 'white Angus' cows in my herd... they're 7/8 to 15/16 Angus breeding... but white - and often give birth to white calves... courtesy of the Charolais color inhibitor gene brought into the herd in a little yellow lineback Charolais-cross cow I bought back in 1986... and/or the Simmental color dilution gene, courtesy of several yellow & white Simmental sires I used back in the late 1980s. 
These girls are phenotypically 'white' , but both are genotypically hetero black...both have produced both red and black calves when bred to red Shorthorn sires... and black or white calves when bred to Angus sires.

can someone post a pic of one?

Is a good question!

Aberdeen x Charolais will produce greyish dark/light, or black, or black white stripe on back, or reddish calves. To turn it white, you must to go again with Charolais. Re-using an Aberdeen bull, will produce always black calves.
This "white" Aberdeen Angus is a new surprise for Mendelian Laws!

Or, a Murray Grey nicknamed!

Confuse with this question. Something isn't on right place in this history.

For the record, I remain an old fashioned Luddite crossbreeder and think all this is hype. However, the hype affirms that interest in non black cattle is growing.
As I understand it, there are two, unrelated White Angus projects. One involves research and development by a Bio-Tech company and involves genetic engineering. I haven't seen a picture of their proposed animals. I think they are gestating right now.

AgFunder Announces AgGenetics Raising Capital to Create New White Angus Breed of Cattle
http://www.onenewspage.com/n/Press+Releases/759i5qfwg/AgFunder-Announces-AgGenetics-Raising-Capital-to-Create-New.htm

AgGenetics, a Nashville, TN-based animal health and biotechnology company, is launching a $5 million equity financing campaign on AgFunder, the leading agriculture-focused online investment platform. The company uses cutting edge biotechnology developed for human medicine to improve livestock health and productivity.
Demand for animal protein is estimated to grow by nearly 40% in the next 20 years[1]. Yet, there is no effective or economically viable model for addressing this demand using common technology, or even through clearing the world’s remaining wilderness.
AgGenetics is developing a suite of products to improve animal productivity that could alone meet the increased demand. Using modern biotechnology techniques initially developed for human medicine — gene discovery and editing — the company is focused on technologies to help farmers combat common ailments that impact livestock production and increase the productivity of cattle. The company’s defining feature has been its ability to identify the right genes in a timely fashion, using genomic and data analysis approaches rarely used in animal health.
AgGenetics currently has three products in late stages of development, including a low-cost test for brisket disease (also called Bovine high-mountain disease), a copper deficiency and toxicity test, and a new breed of heat tolerant cattle. The technology is protected by more than 20 patent applications in countries around the world, including the U.S., Europe, Australia, Asia and South America.


The other White Angus project is a University of Flrida Research Herd that does not involve genetic engineering.
They were going to sell the herd, but called off the sale in January. Posted are photos from the Ona herd. Sometimes these pictures are erroneously posted with press releases from the other endeavor.

Genetic accident produces White Angus
by Burt Rutherford
Sep 09, 2015 
It happened by dint of genetic accident, but a herd of White Angus cattle is contentedly grazing the pastures at the University of Florida Range Cattle and Research Center at Ona, Fla.
The cattle are not pure Angus, of course, but a composite that is genetically three-fourths black Angus but with a white hair coat and dark skin. The remaining fourth is a combination of black Angus, Charolais, Brahman and Simmental, according to John Arthington, Center director.

Here is an example of the Silver dun Galloway (Homozygous for the diluter gene).  This cow was pictured at 7 yrs of age. 

Also known as the original "White Galloway" before the Galloway breed was used crossed with white bred shorthorn to get the white park color pattern.

I also find it comical they are trying to re invent Murray Grey cattle.  Angus cattle genetics with the diluter gene.

 

[Lucky_P]

White cow in this photo is at least 7/8 Angus; making her Angus-sired calf at least 15/16 Angus breeding.
Ancestors of the cow include a presumed Charolais-crossbred cow 3-4 generations back and a diluted-red SimAngus bull 2-3 generations back.
This cow is hetero black...has produced red and black calves by Shorthorn sires, white calves by Angus sires.

Would a white angus have eye problems.......pink eye and whatnot?

 

[Lucky_P]

Pigmentation - or lack thereof - has nothing to do with pinkeye.  I see plenty of cases in solid black or solid red animals.

Personally, despite claims that many make, I'm not totally convinced that periocular pigmentation really has any effect on diminishing the incidence of 'cancer eye'... most of the cases I see arise on the conjunctiva of the eyeball itself or the 'third eyelid'... both of which are unpigmented or minimally pigmented, even on solid color or goggle-eyed animals.
