Executive Summary from the Interbull Steering Committee

An Interbull Steering Committee (SC) web and conference call occurred on April 22, 2013. Main discussion points and decisions are summarized below.GMACE ImplementationAs previously advertised, GMACE regular services will start being offered in conjunction with the August 2013 routine run and more details about this important implementation are given here:· Service calendar: a detailed proposal will be presented by the SC at the 2013 Interbull business meeting in Nantes, France (August 23-25, 2013), in order to consider the feedback from the Interbull community.· The August 2013 run will be considered as a routine run. In Nantes there will be a review of this first routine run. Since it is a completely new service the Interbull SC will decide on the feedback, from when on national genetic evaluation centers will be obliged to make all the results from MACE and GMACE routinely available. The current plan is to require this for the December 2013 routine run.· Distribution files in GMACE runs will include all bulls that have an official/publishable genomic evaluation in at least one country and be known to have semen available for A.I.· Interbull will start offering Truncated MACE services in 2014 to support national genomic programs.o Truncated MACE will use as input national EBVs obtained from the current national model but removing the 4 most recent years of phenotypic data, and its main purpose is to supply data for national genomic validations.o This is particularly important for groups of countries sharing the same reference population for genomic predictions.Publication Policy ProposalThe “Guidelines for minimum requirements for advertising genetic merit of dairy animals” was reviewed to include publication of GMACE results and it is available at https://wiki.interbull.org/public/CoPAppendixV?action=print&rev=7.'''Budget for GMACEAdding GMACE to the service portfolio significantly increases the workload at the Interbull Centre. Therefore, the Steering Committee approved a modification to the service fees in order to cover the associated costs. The adopted fees are expressed in Table 1. Table 1. Fee per service category expressed as a proportion of the fee for MACE - production traits.
