HDT Index (heifer/dairy terminal)

New Zealand Angus Heifer/Dairy Terminal Index - Predicted Response

Expected Change in Individual Traits

CEd CEm GL BW 200W 400W 600W MCW Milk SS DC Cwt EMA Rib Rump RBY IMF
Above the 0 line (X axis) selects for more positive numbers and below
the line selects for more negative numbers. For some traits (e.g. growth),
a positive response is desirable and for others (e.g. days to calving), a
negative response is desirable.

This index is primarily driven by getting live calves on the ground,
and producing an early maturing prime animal with added
carcase traits for improved carcase yield and marbling with no
direct selection for maternal traits.

NB. It is important point to be aware that while no emphasis
has been placed on some traits, for example maternal traits
in the HDT, they still may be selected for indirectly through
positive or negative correlations with other traits, as is the
case with Days to Calving in the HDT.
