  • Unit Activity

    The unit’s basic activities are the testing of milk which is carried out on two levels:
    a) quality control for purposes of payment, and control of the health suitability – this control is for group raw milk in pools.
    b) control of milk increase – this control is for cow’s milk (AT control)
    The good quality of milk achieved by Slovenian farmers today, has not changed significantly over the past five years. However, we believe that it is still possible to improve the quality of milk.
    Other Laboratory Activities
    a) for operators of activities the unit performs microbiological tests on foods of animal origin
    b) the unit performs some tests of clinical material (mastitis)

     

  • Education

    In collaboration with the Centre for Permanent Education at the Veterinary Faculty, the unit prepares courses for milk sampling.
    In collaboration with the Centre for Permanent Education at the Veterinary Faculty, the unit is involved in the education of beekeepers.

     

  • Professional Work

    Milk

    Basic investigations are: determining the total number of bacteria, which is carried out on a Bactoscan FC machine, and determining the number of somatic cells, which is carried out on an Fossomaticu FC.
    The investigation on chemical parameters of milk, the amount of fat, protein, lactose and non-fat solids is carried out on a Milkoscan FT6000 machine.

    Determining the amount of urea and the freezing point of milk using a Milkoscan.

    In 2009 the unit introduced into its work two chemical methods for determining the acid-grade of milk (for the needs of the client) and the assay of alkaline phosphatase, and in 2011 an investigation of the levels of aflatoxin M1 in milk.

     

     

    Food

    The unit performs tests in accordance with EU regulations, or according to customers’ requirements.

     

    Clinical Material

    Tests of milk from udders – investigating the causes of mastitis and analysing antibiograms.
    Tests of animal stools – searching for internal parasites.

     

     

    Scope of Accreditation – Slovene Accreditation Service (SA) Document No. LP021

    1. MILK – DETERMINING protein, fat and lactose in milk (IDF 141c: 2000)

    2. MILK – DETERMINING THE NUMBER OF SOMATIC CELLS IN MILK (ISO 13366-2: 2006)

    3. MILK – DETERMINING THE NUMBER OF MICROORGANISMS – instrumental methods (IDF 196: 2004)
