The longevity of our cows is critically important to Hart Dairy, and it is another key aspect that sets us apart from the dairy industry in general.
The average number of lactations (periods of producing milk that can range from 300-400+ days) in the typical U.S Holstein cow in confinement is less than 2, with an average lifespan of less than 5 years.
In contrast, it is not uncommon in our herds to have significant numbers of cows that live more than 12 years, and still happily producing milk.
Part of this is due to their breeding (we have smaller, more efficient New Zealand Friesian-Jersey cross breeds), and part is because of Hart Dairy's 365-Day Pasture-Raised and Grass Fed farms, including being the first dairy cow milk sold in the U.S. to earn the Certified Humane designation. Our farmers work hard to ensure our cows receive the optimal conditions to live a long, happy, healthy life.
Our cows deserve to live their best lives, and you can taste the difference in our milk.
