Questions from the farm
How should I read an unknown field?
The source supplies no number for that component. If your feed label or laboratory result provides it, use that value in your own ration calculation.
What does a percentage describe?
It describes a component’s share on the stated basis. In feed, % DM uses the portion left after water is removed. Milk-fat percentage describes the share of fat in the milk sample.
How do these figures help in HerdMobile?
Use the tables when preparing your feed and animal-group details. In HerdMobile, select your own feeds and animal group to calculate the daily ration and feed cost per animal.
