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
