Thanks for the input. The main show we are trying to make is the state show in mid Febuary. They have to weigh 225 to make weight. One of the pigs will also be shown in our county show the second week in March---don't know which one yet, as we still have a few more weeks to decide before the tagging deadline, but probably the barrow as he is younger and lighter at this point. Minimum weight on the county show is also 225. The gilt is fairly hard and lean, but the barrow is somewhat softer.
I've noticed several people in our area keeping them on oats from the very beginning, so that's why I was wondering how much to put at this point. I think from what you've said, it may be best to wait and see how they are progressing on growth before adding any.
