benefit of the current system is the easiness to separate the
information
source whether it is
genomic
marker
information
or
daughter
information
. the moment the first
daughter
proven
information
is available, the
genomic
information
disappears 100%. this will in most cases cause some jumps up and down, and mainly down, because the early
daughter
information
is strongly influenced by pedigree
information
, and all vg sires are positive mendelians which means they are better than their parent average. in a couple of index runs this effect will disappear first for the high heritable traits like production and conformation and later for low heritable traits like udder health, hoof health and female fertility ? the traits that have a high focus in vikinggenetics. this means we have to be patient in evaluating if a sire keeps what was promised based on
genomic
information
. a good example right now is vh miracle. today he has ntm +19, which is lower than expected from his
genomic
informa- tion. we hope and trust that he will increase his proof when more data is included. another good example is vh clark ? a d cole son at ntm +24. one year ago he got his first proof based on
daughter
information
and at that time he dropped from ntm +29 to +11. two index runs later (in may) he was up to +24 in ntm. and always keep in mind that the genetic progress is three ntm units per year, meaning a
genomic
sire will auto- matically drop 12 units (3 x 4 years) from his first release of indexes until the
daughter
s start milking.
genomic
sires are on average 12 ntm units higher than the older
daughter
proven - but the reliability is lower. therefore we recommend to use them as a group. r facet
