Interesting, ther must be some big operations out there somewhere.
OK, found this bit on wiki. Works out to a 65 head average for PA.
United States
In the United States, the top six dairy states are, in order by total milk production; California,[42] Wisconsin, Idaho, New York, Michigan, and Pennsylvania.[43] Dairy farming is also an important industry in Florida, Minnesota, Ohio and Vermont.[44] There are 65,000 dairy farms in the United States.[45]
Pennsylvania has 8,500 farms with 555,000 dairy cows. Milk produced in Pennsylvania yields an annual revenue of about US$1.5 billion.[46]
Milk prices collapsed in 2009. Senator Bernie Sanders accused Dean Foods of controlling 40% of the country's milk market. He has requested the United States Department of Justice to pursue an anti-trust investigation.[47] Dean Foods says it buys 15% of the country's raw milk.[48] In 2011, a federal judge approved a settlement of $30 million to 9,000 farmers in the Northeast.[49]
Herd size in the US varies between 1,200 on the West Coast and Southwest, where large farms are commonplace, to roughly 50 in the Midwest and Northeast, where land-base is a significant limiting factor to herd size. The average herd size in the U.S. is about one hundred cows per farm.
