Calculation tool helps with feed ration composition

The new Fertiliser Ordinance requires a new approach to feeding dairy cows. Nutrients must be reduced. The AGRAVIS Phokus ration calculation tool helps farmers to achieve their desired targets.

Specifications in the new Fertiliser Ordinance require optimised nutrient management on many farms with large cattle herds. A feed which is best adapted to the animals’ needs can reduce the quantity of nutrients significantly. Nutrient-optimised feed is easy to introduce and maintains both yield and health.

Optimisation of digestible phosphorus

The new AGRAVIS ration calculation tool Phokus helps to provide a needs-oriented, phosphorous-optimised dairy cow ration. It optimises the ration composition based on the phosphorus which dairy cows can digest in the intestine and takes into account the phosphorus requirement for rumen microbes. This provides a targeted reduction in the gross phosphorus content in the overall ration. The reduction in phosphorus secretion is not the only factor relevant for the amended ordinance. Protein-reduced or amino-acid-optimised dairy cow feed also needs to be taken into account.

Ration calculation saves on feed costs

Taking the farm-specific nutrient and mineral analyses of the silages used as a basis, the AGRAVIS production consultant can use Phokus to calculate needs-oriented, phosphorus-optimised dairy cattle production while taking into account potential phosphorus savings in rations. Appropriate Lakto or Laktaria balance feed and VitaMiral mineral feed are used in the ration composition for this purpose. This new type of ration calculation saves on feed costs and reduces excess phosphorous in rations on a lasting basis.

Reducing nitrogen content in manure

The Laktaria QFit and the VitaMiral ranges also help to minimise impact on the nutrient balance. They help to reduce nitrogen content in manure with amino-acid-balanced feeding. By observing the amino acids when calculating rations, the protein content in dairy cow rations can be deliberately reduced. This saves on protein-rich feedstuff in rations. Protein costs of concentrated feed are reduced while milk and protein production remains the same or higher. These protein savings can be found in the form of reduced nitrogen contents in manure. This reduces the impact of excess nitrogen.
