  • Dairy is one of the largest agricultural commodities in Arizona!
  • Arizona is home to around 45 family-owned commercial dairies.
  • Each dairy has anywhere from 850 head of cows to 10,000 head of cows!
  • There are two very common dairy cow breeds in Arizona dairies. Jerseys are the light brown cows, their milk has a higher milk fat content. Holstein cows are the typical black and white cows that we usually picture when we hear “Dairy cow.”
  • Cows are usually about 2 years of age when they first begin to produce milk.
  • Cows can produce approximately 10 gallons of milk per day and are milked for about 305 days out of the year. This equals about 465.6 gallons per month.
  • A good dairy cow produces about 15,000-18,000 gallons in their 5 to 7 year production timeframe.
  • To make all this milk, cows eat about 100 pounds of feed per day!
  • Despite the date printed on the jug, milk is actually good for about 5 days past that date.
  • 97% of all the milk in our grocery stores is produced right here in Arizona.
  • Local milk is transported from dairy to store within 48 hours!
  • A good way to know if your milk is Arizona milk is to look at the code! If it reads “#04” then it came from a local dairy!

The dairy industry is pretty cool, and there’s a lot more that you can learn about it! Keep an eye out for more posts about dairy throughout the month and take a look at some of our past articles!
