On April 9, Dairy Herd Network told you that the cow had laid claim to the record, but it still wasn't official at that time.

“That’s the equivalent of more than one million glasses of milk,” notes her owner, Eric Patenaude, of Embrun, Ontario, Canada.

The previous record was set in 2006 by a Michigan cow, Tacoma Mark My-Word, which was credited with 471,900 pounds of milk.
