Online calculator illustrates advantages of N-/P-reduced feeding

Sustainable cattle management requires a close look at the nutrient cycles of phosphorus (P) and nitrogen (N). Adjusting feeding offers opportunities to reduce nutrient excretion. At the same time, operating costs can often be reduced with the same milk yield. With the help of the extended version of the RumiTop® N+P Efficiency Calculator from Deutsche Tiernahrung Cremer, dairy farmers can now calculate whether a change in feeding is also worthwhile for their farm and which feeds are suitable for this.

"The legal requirements for the reduction of nutrient and harmful gas emissions are becoming increasingly strict. Cattle farmers should therefore intensively consider the opportunities and possibilities of N+P-reduced feeding," explains Georg Riewenherm, Head of Product Management at Deutsche Tiernahrung Cremer. "With the extended version of the RumiTop® N+P Efficiency Calculator, cattle farmers can calculate a ration adjustment online. In doing so, they always have all the information on the ingredients of the ration, the expected milk yield and the lease and disposal costs incurred at a glance."
New functions enable even more precise calculation

With the "Extended Version", the setting options in the RumiTop® N+P Efficiency Calculator are extended by additional functions. In the new version, more feedstuffs, silages and concentrate variants can be selected. Farmers can now also display their own farm area in an even more differentiated way: It is possible to distinguish between grassland and arable land as well as between leased and owned land. Young cattle rearing can also be taken into account in the current version.

The RumiTop® N+P Efficiency Calculator automatically makes suggestions for the use of a N+P-reduced concentrate with the same content of energy and nXP (usable crude protein at the duodenum) as in the currently fed ration. In the results section, the extended version now also shows the savings potential for manure disposal in addition to the concrete savings in nitrogen and phosphorus accumulation. Farms that already lease land for the application of their nutrient surpluses now find out how much they can reduce their annual lease costs and in which constellation nitrogen or phosphate determines the required area.

Interested farmers can find the extended version of the RumiTop® N+P Efficiency Calculator in the Deutsche Tiernahrung Cremer ꞏ Partner Portal (DEUꞏPA). At www.deupa.deuka.de, farmers can also order feed from the brands deuka, Club, Nordkraft and all pet brands from Deutsche Tiernahrung Cremer. The basic version of the online calculator can still be found on the deuka website at: www.deuka.de/nutztiere/services/n-p-rechner/
