Domestic Terminal Index ($)
Estimates the genetic differences between animals in net profitability per cow mated in an example crossbred commercial herd targeting the domestic market where all calves are sold for slaughter.

Steer (Self Replacing) Index ($)
Estimates the genetic differences between animals in net profitability per cow mated in an example purebred herd targeting the domestic and export markets where replacement females are selected from within the herd.

Steer (Terminal) Index ($)
Estimates the genetic differences between animals in net profitability per cow mated in an example crossbred herd producing steers and heifers for the domestic and export markets where all progeny are sold.

Note: Actual $Index values are sensitive to the assumptions made in the BREEDOBJECT analysis used to calculate the selection index. See Understanding $Index Values for a more detailed explanation.

NB. EBVs and $Index values are calculated using software developed by the Animal Genetics and Breeding Unit (AGBU), a joint institute of NSW Agriculture and the University of New England. Ongoing research and development at AGBU is supported by funding provided by Meat and Livestock Australia.

Accuracy % - Provides an indication of the reliability of an EBV. As more performance information becomes available on an animal (or it's progeny, or relatives) then the accuracy of it's EBVs for particular traits will increase.
