The Ideal Commercial Cow (ICC$) index is a Holstein sire ranking tool developed to meet the demands of GENEX members and customers. The ICC$ index addresses the needs of commercial dairy producers using real-time economic indicators, scientific principles and data-driven genetic evaluations from multiple sources.
ICC$ 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 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 42 million health events on over 8.5 million cows.
What traits are included?
The ICC$ index includes data points from multiple sources, including the Council on Dairy Cattle Breeding, the Canadian Dairy Network and the CRI International Center for Biotechnology. Traits are grouped into the sub-indexes. Traits like Subclinical Ketosis (SCK), Metritis (MTR) and Foot Health (FH) are exclusive to GENEX.
Where can I find ICC$ index rankings?
ICC$ rankings are published with each industry-wide sire summary. The ICC$ index rankings are available in the Holstein Investment Guide, Holstein Sire Catalog, within the MPGSM program and on the website sire catalog.
ICC$ index in the news:
"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."
