    Very few empties and need to move on quiet a few.

    Anyone got views on the value or accuracy of the C.O.W. report on ICBF as a means of identifying cows to cull?

    We use it as guide, it's seems fairly accurate, really penalises high scc cows.

    From a yield pov, if you stop milk recording early, it would penalise a cow with a flat lactation curve.

    I'm struggling to make sense of the figures.

    The 1st lactation cow above giving 321 F&P kg has the same current lactation value as the cow on the next line giving 579 kg....same SCC etc...


    And the 4th lactation cow under that has really no future lactation values compared to the others..

    Might meet ICBF at Dairy Day tomorrow....hold the photo for that..
