April indexrun: new additions to the NVI
Traits including production, longevity and fertility were already part of the NVI merit index. GES will be expanding this formula from April to incorporate hoof health and feed efficiency. In addition, a parallel version of the NVI will be published.
Alongside the NVI for dairy breeds, the GES will now publish NVI calculations for dual-purpose breeds. The breeding value for longevity has also been revised, resulting in more stable breeding values and greater reliability.
