News breeding value estimation December 2017


The national Dutch/Flemish breeding value estimation has been changed in the following way:

  • New breeding value for saved feed cost: Starting april 2016, GES has been publishing breeding values for feed intake. This breeding value displays how much extra feed an animal needs per day. The intake of feed is dependent on the production level of a cow, in which both kg milk as well as milk contents have an influence. Body weight, growth, activity and efficiency in digesting the feed, are also factors that influence the feed intake of an animal.
    GES introduces two new feed intake breeding values in December 2017; Saved Feed for Maintenance (SFM) and Saved Feed Cost for Maintenance (SFC). SFM is based on the breeding value for feed intake, from which the effect of milk production has been subtracted. This leaves the feed amount which is necessary for maintenance. The breeding value is expressed in kg dry matter per day. A positive breeding value means a reduction of feed, so the animal needs less food than an average animal.
    SFC is based on SFM, only this is expressed in the saved feed costs in euros for maintenance during the entire lactation. Because SFC displays the saved feed costs for maintenance in euros and Inet displays the merit of the milk production minus the feed costs for milk production, SFC can be added to the Inet. This results in the profit per lactation based on merit from milk and the total feed costs.
