The Harzer Rotvieh is a unicoloured red cattle breed from the Harz in Germany.
They serve the purposes of providing milk, beef and draught power.
Out of them a local cattle breed developed under the tough conditions of the Harz mountain range.
In the 1950s this cattle breed was crossed with Danish Red bulls to increase milk yields.
In the middle of the 1980s they took remaining animals of the old Harzer Rotvieh (that were already mixed) to synthesize a new population of "Red Cattle, breeding type upland cattle", the Rotes Höhenvieh.
