    I purchased a dairy incalf heifer yesterday and when I looked her up on icbf last night it said she had no ebi value .
    How come ?
    I thought it would be either plus or minus ?
    Is it that the previous owner never recorded or didn't share information with icbf ?
    Can any help me .
    Thanks

    The calf' can only be given a proper ebi if it's parentage has been recorded properly at birth, and if both parents had a proper ebi.

    There could be a combination of reasons that lead to your situation, like the sire was unknown, or not entered on registration, and the dam' s line never had this done either. While for traceability purposes, it's known what cow your calf came from, ICBF would have no way of tracing the ancestry to give your calf an ebi.

    Where it gets strange is, when your heifer will eventually calve down, and you register that calf with a sire with an ebi, the calf will be given an ebi with an average of the sire and dam, but deem the dam to have an ebi of 0. It will take some generations to lift the ebi of the family line of this little heifer calf.

    What's even stranger is that it won't neccesarily be zero.

    I have two heifers with calves by the same AI bull, neither heifer has an EBI or a named sire (and their dams have no ebi)... and yet the EBI of the calves is different between the two.

    Riddle that one!
