| I've seem a few barns legitimately test in the 70# TKN range with wet/dry feeders. However that is a very few barns. More than likely you got too many solids off the bottom of the pit in the sample. If I had to take a guess, I'd assume the sample was taken towards the end of pumping.
Also are these pigs yours or fed for someone else? The other thing to keep in mind is that manure test from most of the larger hog integrators are lower this year for TKN and P2O5. There was wide spread diet reformulation this spring and summer.. Essentially pig companies tried to lower protein costs and/or slow pig growth. These changes had a negative effect on manure nutrients.
I have not seen a single manure test above 70 this year. As such I would not put a lot of stock in the test results you have if I was fertilizing my own corn crop.
