Genetic Evaluations – August 2014
We are pleased to make available the latest genetic evaluation results. With this release of both Type and Production data, we are also introducing the new £PLI which has an increased emphasis on health and fitness. It will see the best Holstein bulls in the August proof run having PLIs in the region of £600.
Bulls have included genomic results since April 2012. Further information related to this release can be found below under ‘Proof Information Documents’
Female Genomic evaluations released by DairyCo and Holstein UK offer farmers new information on their animals to better target their future breeding needs.
The information is based on a combination of the traditional data recorded on each animal, combined with its ancestry information and now also its genomic results. This further improves the accuracy of the genetic indexes, and makes the information on young animals in particular much more informative.
This now means females will receive the full complement of linear type indexes calculated by Holstein UK, alongside all their production and fitness trait indexes calculated by DairyCo Breeding+.
The results of these evaluations are published in three separate lists;
Top Genomic PLI Cows
Cows in-milk which have production data contributing to their genetic indexes.
Top Genomic PLI Heifers
Females under 36 months of age, which do not yet have production data included in the indexes. (Note; some of these may have calved and already be classified, but are too fresh yet to have their production data contributing to the evaluations)
Top PLI Cows (Non Genomic)
The traditional list of milking cows which have both production and ancestry records, but have not been genotyped
