The number depends on the cow, but there are roughly 350 squirts in a gallon of milk. An experienced cow-milker can probably milk a couple of gallons out of a cow a day, but that’s beside the point. The average pail used when milking a cow will hold about a gallon before it fills up completely. That said, the average cow will produce about 350,000 cups, or about 43,750 gallons, of milk in their lifetime when fed properly and taken care of.
Research has shown, however, that when a cow is given a name and treated like an individual, their milk production increases. Sometimes, it can increase as much as 500 pints more than an unnamed cow that isn’t treated like an individual.
