ICC$ Index for Jerseys

ICC$ Index for jerseys

Launched at the December 2017 sire summary, the ICC$ index for Jerseys is designed specifically for Jersey cattle. It puts emphasis on components, fertility, udder traits, health and productive life through its three sub-indexes: Cheese Maximizer (ChMAX$), Sustainability (SUST$) and Fertility (FERT$). Using the ICC$ index will help producers create a more efficient commercial Jersey cow. The inclusion of two proprietary traits will also differentiate the Jersey ICC$ index from other indexes. These two new traits, based on data from 1,800 unique sires are Age at First Calving (AAFC) and Calf Survivability (CSRV)

ICC$ Index for Jerseys Sub-Indexes

Cheese Maximizer (ChMAX$) focuses on pounds of protein and pounds of fat. This sub-index places more emphasis on production and bringing profitability to producers

Fertility (FERT$) contains five measures of cow and heifer fertility, including one proprietary trait Age at First Calving, to meet the needs of producers looking emphasize reproductive efficiency. Selection of bulls with high FERT$ rankings results in optimal age at first calving, reduced days open and shorter calving intervals.

Sustainability (SUST$) is made up of health traits for improved, sustainable health and longevity. Within this sub-index there is a proprietary trait, Calf Survivability. Within the SUST$ sub-index GENEX also created an udder index to include the traits that have an impact on culling rate.

Proprietary Health Traits

Calf Survivability (CSRV)

  • CSRV will bring awareness to the genetics that bring hardness and survivability to newborn calves which is a continual area of concern for the Jersey breed.

 Age At First Calving (AAFC)

  • AAFC highlights the importance of daughter fertility within the breed. Getting heifers calved in early equals bottom line profit.
