Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal level. The online resource models how to make the calculations and provides feedback on participants' feed selection.
