Indices for production for individual bulls
in each group of herd level have been calc-
ulated after which calculations of the corre-
lation between the indices were made. These
are then compared with expected correlation
based on figures for heritability which had
previously been evaluated using the same
material.
For bulls with 30 daughters or more in
each group of herd level there is a very good

report on the study group on standards in AI
agreement between the expected accuracy
and the accuracy found in the progeny-testing.
As regards the youngest bulls which have
their progeny tests based mainly on informa-
tion on three year old daughters the accuracy
of the progeny-tests was very low.
As regards this last item it is argued that
the results are biased by the fact that annual
production is an inaccurate criterion for the
production performance of heifers.
