Aurochs

Aurochs would be a new neutral mob replacing cows in worldgen, except for villages.

Being around 2 and a half blocks tall and 5 blocks long with very large horns, they would be found commonly in plains, savannas, windswept hills, and rarely in forests and drop more meat and leather than a normal cow, since they would attack the player back when provoked.

They would also come in two different colors: black and brown, both having a white stripe running down their spines.

To get cows you would tame two aurochs and give them wheat so they can breed, their offspring would be a cow or, alternatively, get cows from villages.
