Wisconsin has 21 digesters on dairy farms capable of producing over 75 million kilowatts of electricity per year.

ANother article notes ~1200 kwhr/year per cow for Biogas. This was in 2004.

This article notes some interesting facts about the various digestors in Wisconsin. It seems like the power potential is pretty impressive for large farms. (2000 cows)

Not sure what a good number is for per cow potential, but the latest numbers seem to be showing some impressive gains. Would other animal waste off better potential? Not sure. Seems like the US has a lot of options though. Dairy farmers who install the digesters directly on their property, allows the waste to be collected immediately, for prime quality. So perhaps the viability is better the closer to the source?
