DOC, those calves just aren't shed off yet.
I know a lot about copper deficiency in cattle
and this red tinge throughout their body
is NOT the sign of copper deficiency.
Copper deficiency is characterized by a triangle shape up by their shoulders, kind of where
a wither would be on a horse. And in the picture of all the cows,
I didn't see one cow that had that characteristic. If you look
closely, I think you will agree it is merely hair that hasn't shed.
These calves could have a worm load, but they aren't copper
deficient. I'd bet my life on it.
Denny, I'd take a fecal and check them for worms...I can tell
you where to send it and it won't cost you a cent.
WARNING: don't take it to your local vet. Most of them don't have
the proper equipment to check for parasites in cattle. What they
have is for dogs. Ask your local vet if he has a Wisconsin Spinner.
If he does, then he can check the fecal accurately. (BTW, I only know of
ONE vet who has a Wisconsin spinner.)
Nice stout calves. Things look good in your country.
