EBV emphases (%):
This red bar-graph shows the emphasis on individual EBVs that is aimed for in the New Zealand Simmental Terminal $Index. The signs indicate the directions of the emphasis. For example, greater 400-Day Weight EBVs are favoured.
The EBV emphases reflect the underlying profit drivers in the commercial Simmental terminal crossing to British breed cows where there is only a moderate concern about calving difficulty and all progeny are slaughtered. The emphases take account of the genetic relationships between the trait EBVs and the relevant profit drivers.
When $Index values are calculated, the weightings that are applied to each EBV are in actual units ($/kg, $/mm etc). In this graph these weightings have been converted to standardised percents (%) to illustrate the relative emphases.
