ICC$ Index for Holsteins

Data-Driven Genetics for the Ideal Commercial Cow

The Ideal Commercial Cow (ICC$) index is a sire ranking tool developed to meet the demands of GENEX members and customers. The ICC$ index addresses the needs of commercial dairy producers using real-time economic indicators, scientific principles and data-driven genetic evaluations from multiple sources.


What traits are included in the ICC$ index?
The ICC$ index is the summation of five easy-to-use sub-indexes. The sub-indexes enable you to narrow genetic emphasis to specific areas of farm management. The sub-indexes and their weightings with the ICC$ index are: 46% Production Efficiency (PREF$), 24% Health (HLTH$), 15% Fertility and Fitness (FYFT$), 10% Milking Ability (MABL$) and 5% Calving Ability (CABL$).
How is genetic progress achievable with the ICC$ index?
The combination of trait weightings, each individual trait's heritability, and trait correlations and relationships enable ICC$ to accomplish the goals established by GENEX members and customers.

What is the validity of the ICC$ index as a sire selection tool?
The ICC$ index was thoroughly reviewed and validated by dairy geneticists with doctorates in animal breeding and previewed by commercial dairy producers for their grassroots input.

What data is included?
The ICC$ index includes data points from multiple sources, including the Council on Dairy Cattle Breeding, the Canadian Dairy Network and the CRI dairy research database. The CRI dairy research database is comprised of 54 million health records on nearly 12 million cows as well as AgSource Dairy records (milk testing and herd management information) with more than 720,000 cows tested monthly.

Where can I find ICC$ index rankings?
ICC$ index rankings are published with each industry-wide sire summary. The rankings are available online in our sire catalog and in the MPGSM program.
