The analysis behind that link suggests 70% of US cows live on factory farms.
They use a cut-off of >150 cows on a dairy farm or >225 cows on a beef/veal farm = factory farm. The supporting sheets indicate that they take a simple 75% of the Small farm (300 head or 200 head for beef or dairy) maximum size as their cutoff for a factory farm. It doesn't explain why they use such an unsophisticated metric to define many small farms, and all medium- and large-sized farms, as factory farms.
That lack of sophistication makes me skeptical of these numbers.
