Determining the curve for daily feed amount
The control computer first determines the curve for the daily amount per feed place based on the feed curve, curve
day, animal weight and the number of animals at the feed place.

For example a feed curve has bending points on curve days 7, 14, 21, 28 etc.

The control computer takes the feed amounts on days 7 and 14 from the feed curve and calculates the feed
amounts for the days between. The feed amount increase in steps. For a feed place with 10 animals the daily
amount in the curve is * 10.
The description is based on a feed curve based on a portion size. However feed curves can also be set based on the
energy value (EV). If the latter method is used changing the feed composition will result in a different portion size.
