Buying corn bulk, I pay $280/ton ($7/50#). I was paying $175 last year!!!!
Basically, I feed them out for 6 months - fed 2x/day - clean up in 10-15 minutes, with full grass or hay. This is rough estimating, but if they averaged 10#/day for 3 months = 900#
20# for 3 months = 1800#. Total is 2700#/hd. That would be $378 for corn for 6 months. This does not include the protein pellets, grass/hay. But, at most I have $500 feed cost in them and sell them for about $2800. They were worth ? $900/hd after weaning, so that's about $1400 profit for 6 months of labor feeding them. I think that pencils out pretty good in my pocket. Granted, these are VERY loose figures, but I'm pretty sure it's not too far off.
