Sustainable, N-efficient and GMO-free feeding on dairy farms in Schleswig-Holstein
The feeding of Schleswig-Holstein dairy cows is constantly calculated and optimized by specialized advisors and experts of feed suppliers. A question that arises when implementing diets with reduced protein content but not yet answered and analyzed is: How much protein requires the dairy cow really or how can we make the feeding more N-efficient? The OG Milk - feed & feeding aims with the innovation project to contribute to the efficient use of protein feed for dairy cows. The reduction of protein content in the total ration leads to decreased nitrogen excretion via the liquid manure and therefore to a reduction of nitrate loads from animal excrement into the environment. Feed protein of this project should also increasingly come from native production to guarantee a GMO-free feeding for the consumers.
Comprehensive and constant feed monitoring is the cornerstone for efficient milk production. The following recommendations are derived from the project for the eight participating dairy farms:
The optimum protein content in the ration is determined by a ration calculation. The recommendation is an nXP content (nXP: usable crude protein) of greater than 15.0 % to 15.4 %; this achieved the best combination of good efficiency and maximum milk yield with 31 kg of energy-corrected milk (at approx. 200 mg/l urea).
The control indicator is the milk urea content, which should be between 160 and 220 mg/litre.
Following a ration adjustment on a project farm, the following result was calculated as an example: Reducing the nXP value by 1 % meant a cost saving of 0.08 euros per cow per day.
