On average how many cows contribute to a gallon of milk?

Answer 1

A cow produces about five gallons a day. But, the gallon of milk in the store contains some milk from every cow on the farm. All the milk is sent through the process together and gets mixed together in the tanks. Being you probably buy your milk in the grocery store and not from a farmer, there are thousands of cows milk processed together from not one farm, but from hundreds of farms at the creamery. So an average is fairly hard to come by as it depends upon many variables. Some large farms send nearly 80,000 lbs of milk or more per day while a small farm may send as little as 400 lbs.
