Gerold, How much pasture do you have them on and what do you do in winter? Is corn the only grain you give in addition to pasture?
20 acres pasture now. 5 ac. plots. Wheat and Rye in one pasture, oats wheat in another, Different grass etc. in another big pasture. Peas, milo in another pasture. Still have a lot of good pasture for them.
They have lots of grasses in the winter to forage on and 20 acres of woods with hazel nuts,hickory nuts and loads of acorns this year.
Corn plus molasses a mix of vitamins plus minerals. I haven't mixed soy bean in for awhile now. They are gaining very well on the diet i have them on.
I had to cut back on the sows corn diet as they were getting to fat and will have little ones in a few weeks.
Had a problem getting organic soy so cut it out of their diet.
I did try distillers dried grains on some of the pigs a few months back. Very high protein but for some reason they just didn't do well on it.
Corn is still king for me. Produces great solid meat with just enough fat to make good sausage. I had two big hams ground into sausage with the latest hog i butchered. Going to have some really nice bacon which will be finished coming wed.
I have two 20 acre fields that is over grown with a bit of brush and different wild grasses. I would like to use them next spring if the price of pork and the demand for breeders stay good. If the market drops i will not use them and just keep the pigs i have now.
P.S. A little off tropic . Deer season opens this coming sat. Two people will bring me a young deer and get a roaster pig in return. Plan on grinding up the whole deer with pork for some nice sausage.
