George, like you I find the hogs to be a reliable business. Down here the real market occurs in December. Venezuelans prepare a special dish during the Christmas-New Year's holiday and the main ingredient is pork. They go crazy in December looking for hogs.
Feed prices have gotten so high though that many of the smaller hog producers have all but given up.
I sort of modified my program. First off, I produce as much of my own feed as possible. Secondly, I enclosed a rough area on my place of about 50 acres with an electric fence and for half the year my feed costs drop to virtually zero. During our "winter" or wet season, there's plenty of natural forage for the animals and I've got a large pond there as well.
The largest of my animals will be released within a week or so into this pen and I'll pull them out in late November in anticipation of December sales.
Also cuts down dramatically on the smell.
