Some producers already know that there is gold in byproduct rations for hogs. Granted it may seem futile to look into alternative feeds when corn prices are so low. But for some of you who aren't in the Corn Belt or who are located next to a byproduct market, alternative feed grains are worth considering. Your first step, however, should be to talk to a nutritionist.

Take stale bread for example, it can easily be substituted for grains in swine diets.

Here are some guidelines, provided by the Kansas State University Extension Service, specific to feeding bread products to hogs:

Bread is 75 percent to 80 percent as valuable as corn for hogs. So, if you can buy the byproduct for 75 percent to 80 percent of the price of corn, it can be an economical alternative.

You will need to boost dietary fiber levels, because bread is typically low in fiber (less than 1 percent).

The moisture content of bread (36 percent) is higher than corn (10 percent). It also has a lower fat content. Combine those two factors and the bread byproduct will contain less energy. Other bakery items such as doughnuts or cake are higher in fat than bread.

Rations containing bread will need a vitamin and mineral boost. An analysis of the byproduct and a consideration of other ration ingredients will target which and how much vitamins and minerals you need to supplement.
