ICC$ Index for Holsteins

Ideal commercial cow index for holsteins

The Ideal Commercial Cow (ICC$) index for Holsteins is a Holstein sire ranking tool developed to meet the demands of GENEX  customers. The ICC$ index addresses the needs of commercial dairy producers using real-time economic indicators, scientific principles and data-driven genetic evaluations from multiple sources. The ICC$ Index for Holsteins is made up of five sub-indexes: Production Efficiency (PREF$), Health (HLTH$), Fertility and Fitness (FYFT$), Milking Ability (MABL$), and Calving Ability (CABL$). Within these sub-indexes there are three proprietary traits.

ICC$ Index for Holsteins Sub-indexes

The Production Efficiency (PREF$) sub-index pinpoints genetics resulting in high yielding cows with lower feed costs. Emphasis is placed on pounds of protein. Use of PREF$ and ICC$ reverses the trend for taller cows.

64% total yield, 36% feed efficiency indicators 2:1 Protein to Fat ratio Marginal feed costs includes production costs and body maintenance costs Selects for ideally sized commercial cows

The Health (HLTH$) sub-index breeds for improved, sustainable health and longevity. High-ranking HLTH$ bulls have daughters with proper body condition, low somatic cell scores and excellent locomotion. With inclusion of the proprietary health traits SCK, MTR and FH, this sub-index also selects for lower predicted blood BHBA and fewer cases of metritis and lameness.

  • Improves overall health and longevity
  • Incorporates Body Condition Score and locomotion breeding values
  • Includes proprietary SCK, MTR and FH breeding values

With nine measures of cow and heifer fertility, Fertility and Fitness (FYFT$) meets the needs of producers looking to emphasize reproductive efficiency. Selection of bulls with high FYFT$ rankings results in optimal age at first calving, reduced days open and shorter calving intervals.

  • Emphasizes fertility selection with nine measures of cow and heifer fertility
  • Assigns a slight economic advantage to the polled genotype

Milking Ability (MABL$) optimizes efficiency with trouble-free milking cows. MABL$ includesmastitis resistance, milking speed and temperament, and ideal commercial udder conformation and function. Ideal udders have strong attachments; are above the hock; and include proper teat placement and length. Choosing bulls using MABL$ enhances udder texture and manages the emerging trend of short teat length.

  • Optimizes milking efficiencies
  • Incorporates Mastitis Resistance breeding value
  • Udder selection emphasis includes udder depth, attachments, teat length and placement
  • Specifically manages rear teat length and placement

Calving Ability (CABL$) focuses on live calves born without difficulty. High-ranking CABL$ sires with high ICC$ values can maximize genetic progress in heifer pens while ensuring an easy transition into the milking string.

  • Selects for the ability to have live calves born without difficulty
  • Emphasis on Sire Calving Ease to minimize assistance needed in maternity pens

Proprietary Health Traits

  • Subclinical Ketosis (SCK)

    • Subclinical Ketosis (SCK) breeds for cows that transition better and have lower incidence of ketosis. SCK is set to a base of 100, meaning a value of 100 is average.
  • Metritis (MTR)

    • Metritis (MTR) selection leads to daughters that experience fewer cases of metritis. MTR values come from a database containing more than 42 million health records and over 8.5 million cows. MTR is set to a base of 100
  • Foot Health (FH)

    • Foot Health (FH) selection will lead to cows with fewer foot health issues. FH values come from a database containing more than 42 million health records and over 8.5 million cows. FH is set to a base of 100.
