Colour Marking?

[creekdrive]

Had a calf born with an interesting colour marking... Shown it to a few people and they all said they'd seen something similar before, but does anyone have any idea what exactly causes it?

Red calf, the stripe is tan and just on one side...

Sire is mostly Red Angus, 1/16th Sim. Dam is over half Red Angus with I would guess a little Sim and possibly something else in the mix but don't know for sure.

Galloway/buelingo maybe?? I don't know how their markings would act as "hidden traits" and skip a generation though... ANAZAZI seems good with explaining colors and genetics, maybe he can tell us :???:

I'd call it a birthmark. We had a black wf calf a couple years ago with a similar marking. It was round though. Looked funny but that's all.

Clearly not Galloway or Buelingo... if it was a beltie cross, the mark should be white.

I believe its just a birthmark. I think 3waycross had a calf that has a birthmark.

It's a birth defect! You better hide it behind the barn! :lol:

Just joking, I would also call it a "birthmark." I occasionally see it on my black calves as a reddish color or even some white hairs. It kind of blends in or fades away over time on mine. Rarely see it still there as adults.

Bez. I deifinitely agree that cow doesn't look very good. I'm not trying to make excuses. It was a hard winter and about 20 of the second calvers got down in condition pretty bad. They were split off from the main herd for awhile but we noticed a little late. Should have been more on top of things i know. All of the cows were a little thinner than most winters but the majority are still in good weight. Just so people don't think that all are cows are that skinny here's a picture of a more typical one.

Posting from my phone so hope this works.

And I was leaning towards some kind of birthmark on the calf as well. Have seen other birthmarks but not quite like that. Will be interesting to see if it fades away or is there to stay
Thanks for the responses!

I have seen it live two times in my life, and 3way posted one on here a while ago. I figure there is a local mutation in that area of the hide, therefore not heritable. A fluke of nature, a birthmark if you will, even if I am used to call darker spots birthmarks.
A basic explanation would be that the red pigment is diluted in that area, possibly in the same way as some simmenthal cattle.
