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 about 4-5 years.
In contrast, it is not uncommon in our herds to have significant numbers of cows that are 10, 12, or more years of age, 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 the healthy, free-range, Certified Humane environment they enjoy on Hart Farms, as they are free-range and grass-fed 365 days a year. Our farmers work hard to ensure our cows receive the optimal conditions to live a long, happy, healthy life.
We are the first - and only - pasteurized dairy farm in the United States to earn the Certified Humane designation. Our cows deserve to live their best lives, and you can taste the difference in our milk.
