The by-products of the dairy are more highly prized by hog-men than perhaps any other form of protein supplement. The value of skim milk and buttermilk is such as to make pork production a valuable adjunct to profitable dairying when either of these products are available for swine feeding.
...or in other words 4.18 pounds of milk had the equivalent of 1 pound of corn. (for weight gain-ed)
We don't feed our hogs much pure corn. However, an added incentive for feeding milk is the taste of the pork. The pork from hogs feed milk as a supplement has a sweet creamy taste not found elsewhere.
Oremus pro invicem!
