Quality control in accordance with the Milk Quality and Payment Regulation (MilchGüV)

The “regulation for quality control and payment of the delivered milk” regulates the testing frequency for

  • fat and protein content
  • somatic cell count
  • bacteriological quality
  • determination of freezing point
  • verification of the absence of inhibitors

Moreover, the regulation sets limit values for bacteriological quality and somatic cell count relevant for the payment.


Test criteria Analyses per farm an month                                                                        Averaging and accounting period
Fat/protein content 6 x Arithmetic mean of the current month
Somatic cell count 4 x Geometric mean over 3 months
Bacteriological quality/Bacterial count 2 x Geometric mean over 2 months
Determination of freezing point 4 x Arithmetic mean of the current month
Verification of absence of inhibitors 4 x Only single values of the current month are relevant


The tasks of the Milchprüfring Bayern e.V. also include the classification of the results with regard to payment of the delivered milk and also data communication for the billing of the milk to the dairies and its assigned data centers.


The basis of the milk price paid by the dairies are fat and protein content of the milk.

The standard amount has been determined since January 1, 2006 at 4.2 percent fat and 3.4 percent protein. For higher and lower milk ingredients the dairies accordingly apply a surcharge or a deduction. Furthermore, there apply regulations for the quality status of the milk. Thus the results of the activities of the Milchprüfring Bayern e.V. are a very important basis regarding the milk payment of the dairies to the farmers.


Six resp. eight samples which are randomly distributed over the month from each dairy farm are used in order to perform this task. Many dairies use this possibility to test even more samples. These samples are taken by automatic sampling devices in the milk collecting trucks and are analyzed under a strict quality management regime with no advance notice to the dairy farmers. These samples form the basis of the laboratory analyses for fat, protein, somatic cell count, total bacterial count, freezing point and inhibitors.

LIMIT VALUES WHICH APPLY to the quality payment are regulated by the mgvo as following:

S-quality grade

≤ 50.000 germs/ml

≤ 300.000 somatic cells/ml

Quality grade 1 ≤ 100.000 germs/ml
Quality grade 2 > 100 000 germs/ml
Somatic cell count limit < 400.000 cells/ml
Limit value freezing point -0,515 °C

No inhibitors verifiable
