Move to the Provide amounts tab and give the kilos or grams of the different feeds you want to use. The screen is empty until you enter your amounts. You can give amounts directly in the table, or change allocations of individual feeds by using the arrow buttons.

PC-Horse shows a limited graphic representation of how well the nutrients in the ration will cover the requirements of the horde. You should adjust the allocation of feeds in order to achieve nearly 100% covereage on the requirements for energy and the indicated nutrients. If you have difficulties with formulating a balanced diet, you should go back to Select feed page, and select suitable feeds.

The panel at the bottom of the screen will keep you informed about the total amount of drymatter and roughage in the ration, and warn if the roughage allocation is outside the optimal.
