One of the many problems facing swine producers is in the feeding of their livestock—Are the rations used both efficient and economical? The problems are complicated further by the changing nature of the prices of the different feed ingredients used in the rations and the changing nature of the restrictions of the rations as new nutritional knowledge becomes available. The nutritionist may tend to report nutritional knowledge from a performance standpoint while a swine producer tends to look at the economic returns as his measuring criterion. The basic problem is to blend nutritional information with the economic goals of the swine producers.

To solve this issue, specific areas must be examined closely, including:

1) Feed rations which incorporate the latest nutritional knowledge.

2) Feed that is both nutritional and economical in cost.

3) The effect of ingredient price changes in ration composition.

4) The per unit cost of critical ration restrictions.
