Simmentaler Fleckvieh

Ah thank you bayucca!

Genetically all domesticated cattle are called Bos primigenius taurus, independent from the race/breed. They are formerly also called Bos taurus.

Thank you very much for the help!

That's a specie of Simmentaler Fleckvieh from Switzerland, but they don't seem to have a scientific name and every region developed his own new breedings in Bavaria and Austria.
