Future table revisions

A feed composition table is of value only if it's relatively complete and contains feeds commonly fed, and the data are constantly updated. Suggestions and compositional data to keep this table useful to the cattle and sheep industry are welcomed.

When sending compositional data, adequately describe the feed, indicate the DM or moisture content and if the analytical values are on an as-fed or DM basis. If more than one sample was analyzed, indicate the number of samples analyzed.
