The Ideal Commercial Cow (ICC$) index is a Holstein sire ranking tool published exclusively by GENEX. The ICC$ index uses real-time economic indicators and scientific principles to address the needs of commercial dairy producers. The index includes science-based and data-driven genetic evaluations from multiple sources.
ICC$ is the summation of five easy-to-use sub-indexes. The sub-indexes enable producers to customize or narrow their genetic emphasis to specific areas of farm management. The sub-indexes include: Production Efficiency (PREF$), Health (HLTH$), Fertility and Fitness (FYFT$), Milking Ability (MABL$) and Calving Ability (CABL$). Learn more about each ICC$ sub-index.
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. The index incorporates genetic evaluations from multiple sources include the Cooperative Resources International dairy research database which contains more than 26 million health event on nearly 4 million cows.
Where can I find ICC$ index rankings for bulls?
ICC$ rankings are published and updated with each industry-wide sire summary. The ICC$ rankings are available in the printed GENEX Holstein Investment Guide and Holstein Sire Catalog. The Investment Guide also lists the top 25% of the lineup for each ICC$ sub-index. ICC$ numbers can also be found via the MPGSM program and the website sire catalog.
The ICC$ index in the news:
• Lifetime Production Achieved Faster with ICC$ Selection
• Proprietary Health Traits to be Included in ICC$ Formula Update
"If I were breeding cows, this is definitely the index I would be using. I like your objectives
of improving body condition, reducing stature, improving feed efficiency, reducing SCS,
improving reproductive and calving performance, etc. I agree 100% with all of the
innovations you have built into this index."
