In MACE, relationships between animals are correctly accounted for. The Industry agreed MACE linears are more accurate than converted linears. This is the same procedure as is currently used to produce composites from converted proofs. Adopting this composite enables a new method of TM prediction. This composite will be calculated from the MACE linears.
Mammary composite is a subjective trait, composed differently in each country.
By calculating the composite from the MACE linears it allows the traits that are included in the composite to be determined by us, not each individual country. Type Merit Type Merit will be calculated by weighting the four composites. It will be easy to control Type Merit if the weights on the composites are altered. These weightings are applied before the composites are scaled. Effectively this information would not be used anywhere.
