comparison only of animals which have had like treatment is one of the most
important aspects of BREEDPLAN. These like-treated groups are called
management groups. If the groups are not reported correctly, EBVs will be
less accurate and possibly misleading. It is also important, to ensure that
weights from all animals in a group are submitted.
1. Assign animals to different management groups where they
have been treated differently. However, be careful not to create unnecessary management
groups as this conflicts with point 2.
2. Run animals in large groups. Larger groups provide
more information for EBV calculations.
3. Establish pedigree links. This can be achieved by
ensuring two or more sires are represented in each management group. The more, the more reliable the EBVs.
