What is the validity of ICC$ as a sire selection tool?
ICC$ has been thoroughly reviewed and validated by dairy geneticists with doctorates in animal breeding and previewed by commercial dairy producers for their grassroots input.
Where can I find ICC$ sire rankings?
ICC$ rankings are published and updated with each industry-wide sire summary. The ICC$ rankings are available in the Holstein investment guide. MPG and the website sire catalog include both the ICC$ and the sub-index values. MPG also includes ICC$ values on all bulls industry-wide that have a published genetic evaluation.
How is genetic progress achievable with ICC$?
The desired genetic progress of individual traits from the perspective of members and customers, along with industry trend research, aids in determining which traits are part of the ICC$ index and assigning the weighting of each trait. The combination of trait weightings, each individual trait's heritability, and correlations and trait relationships enables ICC$ to accomplish the goals established by members and customers.
What traits are included in ICC$?
ICC$ for Holstein is the combination of five sub-indexes - Production Efficiency (PREF$), Health (HLTH$), Fertility and Fitness (FYFT$), Milking Ability (MABL$) and Calving Ability (CABL$).

ICC$ Index for Jerseys is based on a combination of 3 sub-indexes--Cheese Maximizer (ChMAX$), Sustainability (SUST$), and Fertility (FERT$). The ICC$ Index for Jerseys includes two proprietary traits: Calf Survivability (C SRV) and Age At First Calving (AAFC).
How does ICC$ compare to other selection indexes?
ICC$ is a more productive way to rank Holstein and Jerseybulls. With ICC$, producers have the most effective tool to identify genetics that excel in progressive commercial conditions.
