    Update of the limits for feeding control in the LKV daily report

    An optimal and balanced supply of energy and protein to the cows is an essential prerequisite for economical and environmentally friendly milk production. Current scientific work shows that the basic formula for milk ingredients currently used for feeding control is no longer up-to-date. The aim of this activity is to set new limit values ​​for assessing energy and protein supply based on the fat, protein and urea content of the milk.

    , rigid limits have been used in Austria to evaluate the protein content These limits are 3.2% to 3.8% . In Germany, a new method has already been developed, which is called the “Dummerstorf feeding recommendation” milk yield when evaluating the protein content (Method 2). This new German method is applied to Austrian LKV data and adapted to Austrian conditions if necessary (Method 3). For this purpose, LKV Austria will provide all test milking results from the control years 2017 to 2021. These are passed on anonymously to the HBLFA Raumberg-Gumpenstein.

    This project aims to find out which method can best be used to assess energy supply The three methods are tested using energy balances and metabolic parameters from previous Gumpenstein feeding trials. The goal is to ensure that the LKV feeding control corresponds as closely as possible to the results from previous feeding trials.

    The method that provides the highest level of agreement should be implemented LKV daily report In this step, the tables and graphics in the daily report should be revised and adapted to the new limit values. In order to provide farmers with additional information, the results of tank milk tests are also included in the tables and graphics.
