In order to compare two feeds with different moisture contents in terms of their protein, fat, fibre and carbohydrate contents, it is necessary to convert the respective contents to dry matter.

This way you can also compare the energy content of different products, which is especially interesting for light products. The term "light" is not a protected term, so it may be that the light food from company X contains just as many calories as the normal food from company Y. "Light" simply means that it is the lowest calorie food from the corresponding manufacturer.

Instructions: Enter the contents of moisture, crude protein (Rp), crude fat (Rfe), crude fibre (Rfa) and crude ash (Ra) indicated on the packaging in the table. If no moisture content is indicated for dried fodder, enter 10%. The carbohydrate content (NfE) is calculated automatically.

Here you can enter the names of the feeds.
