Humans have turned the wild aurochs into “milk tanks on hooves” — just look at Yaroslavl and Kostroma cows. Some of these animals consume up to 220 pounds of feed a day and produce 15 gallons or more of milk.
Take, for instance, a relatively small Yaroslavl cow named “Vena,” who once produced an astonishing 82 liters of milk in a single day — that’s over six buckets. Then there’s the Simmental cow “Zozulya,” who yielded 59 kilograms of milk in one milking; that added up to as much as 28,200 pounds in a year. Meanwhile, a Kostroma cow named “Kamsa” managed to produce up to 29,900 pounds annually — equivalent to an entire tank!
