Rye Calculator

Calculate your saving potential with more rye within 3 steps:

Saved Feed Cost
Saved nutrients N and P
Fibre for more animal health

The SU Rye Calculator can compute your advantage in a matter of minutes. This does not replace an individual ratio needs assessment but gives hints for optimizing the feed management. This is based on the official DLG recommendations and the calculation according to the Löhr method (energy density and digestible lysine).

Info: DLG recommends

Farmers can save even more P- und N with free Amino acids.
Your Benefit with more Rye:
Saved feed cost	-5.8 %	You save 51,923 £
Lower N intake	-5.0 %	You save 624 kg N
Lower P intake	0.8 %	You save 34 kg
Fibre for animal welfare	+24.7 %	You increase 10 kg

For the same energy and pc-Lysin content a higher or lower feed amount could be possible.
