The routine laboratory of Qlip is commissioned by the recipients of farm fresh milk, to perform payment criteria analyses on tankmilk. These samples are analysed based on composition (e.g. fat-, protein-, lactose- and ureum concentrations) and quality (e.g. total cel count, total plate count, butyric acid, and cleanliness). Depending on the results, the recipients of farm fresh milk will issue deductions or bonuses to total payment rewarded to the supplier. General rules for the payment of farm fresh milk are recorded in the ‘Regelgeving Uitbetaling Boerderijmelk’ from the Dutch Dairy Board.
