If you're just wondering about breakevens for livestock if you by chance have access to a DTN they have a page that lists breakeven purchase prices for cattle and hogs with current feed and market prices.

Its not 100% accurate but it is close enough to give an idea whether or not you need to be nervous about the financial condition of who you're feeding for.

I think its in the livestock page but I'm not sure where to go after that. Like a lot of things I can find it when I'm looking but giving directions is far more difficult.
