Terminal Sire Index (TSI) The AICA Terminal Sire Index (TSI) is a formal
method of combing Expected Progeny Differences (EPD) – BWT, WWT,
YWT, REA, HCW, MARB and FAT – into one single value on which to base
selection decisions. The TSI uses estimates of the genetic relationships
between traits with an economic default value based on three year rolling
USDA data.
The TSI represents a dollar index per terminal progeny produced for a bull
in the AICA database, ranking them for profit potential. This dollar index is
to be interpreted much like single trait EPD. For example, if Sire A’s index
is $191.66 and Sire B’s index is $200.00, then we would expect Sire B’s
offspring to average $8.34 more net return ($200.00 minus $191.66) than
Sire A’s offspring.
