August 2022 Evaluations: What’s New?
August 9, 2022
In addition to the Brown Swiss health traits, CDCB implemented three other changes in the August 9, 2022, triannual evaluations.
December 2021: Changes to Evaluation System
December 1, 2021
Genetic evaluations for Residual Feed Intake (RFI) were improved using variance adjustments and a higher estimated heritability. The RFI records are now adjusted to have equal variance across herds and across first versus later parities.
August 2021: Changes to Evaluation System
August 1, 2021
The new Lifetime Net Merit (NM$) including Feed Saved (FSAV), Heifer Livability (HLIV) and Early First Calving (EFC), along with a number of new parameters and assumptions, will be introduced in the August 2021 evaluation.
April 2021: Changes to Evaluation System
April 1, 2021
Several small adjustments to fertility traits editing will be introduced with the April 2021 evaluation to better account for late-term abortions. Fertility credits for traits Heifer Conception Rate (HCR) and Cow Conception Rate (CCR) now treat the last service as a failure instead of success if the next calving is coded as an abortion.
