ICC$

What is the Ideal Commercial Cow Index (ICC$)?

Lifetime production is achieved faster with Ideal Commercial Cow (ICC$) index selection. Every farm strives for profitable levels of milk, fat and protein yield. Cows that are healthy have the ability to maintain consistent production levels and breed back regularly. ICC$ is a superior tool to select the best balance of healthy fertile cows with high production. ICC$ is a sire ranking tool that was first released in August 2014. Building on its reputation for innovation, Genex created the index after producers asked for a better way to rank sires that create cows which excel in commercial conditions. The ICC$ index for Holsteins was updated in December 2016 to include three cutting-edge proprietary traits: Subclinical Ketosis (SCK), Metritis (MTR) and Foot Health (FH). ICC$ incorporates science and data-driven genetic evaluations from multiple sources including the cooperative’s research arm, the CRI International Center for Biotechnology (ICB). The CRI ICB research database includes nearly 4 million cows and 26 million recorded health events. The ICC$ Index for Jerseys was first released in December  of 2017. This index use three subindexes to help Jersey producers improve their efficiency. With the release of this index two new proprietary traits were released: Calf Survivability (CSRV) and Age at First Calving (AAFC). 


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.

"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."

- Dr. George Shook, Professor Emeritus, Dairy Science Department, University of Wisconsin-Madison

When sourcing overall profitability for the next generation consider the Ideal Commercial Cow (ICC$) index. The index measures the net profit over the lifetime of the bull's average daughter. For producers seeking improvement in specific genetic or herd management areas, use one of the targeted indexes described below to fine-tune your sire choices. The top 25% of the lineup for each of these indexes is published in the GENEX investment guide.
