Feed skim milk, corn and molasses
Hold them in crates.
Low fat milk is the sugar concentrated part of the milk (Lactose). The fat has been removed.
Barley, wheat or corn can be used as feed, but corn is best.
The pigs will eat more if the corn is sweetened by molasses or sugar cane water. Lucky farmers who can get waste for a biscuit factor or a confectionary manufacturer, can get especially fattening waste products that are excellent for fattening pigs.
