PCR Ranking - Select your bulls for crossbreeding

The exclusive ProCROSS index

ProCROSS, with 20 years’ experience in dairy crossbreeding, has created a unique index adapted to the selection objectives of modern dairy farmers: the PCR index.
The ProCROSS PCR index has been developed to make bull selection easier when it comes to the ProCROSS crossbreeding program. This modern index is focused on the specific selection criteria of dairy crossbreeding.

The PCR is a practical selection tool, which ranks bulls according to their native index, ISU for Montbéliarde Coopex & NTM for VikingRed. The PCR index will help dairy farmers around the world to select the most suitable bulls for their crossbreeding strategy.
1 index, 2 expressions

PCRs - Fat & Protein Production oriented 

PCRL - Milk Yield oriented
All other traits are equally weighed in both PCR options
PCR index objectives
With the PCR index, your herd will: 
  • Be medium-sized, Homogeneous
  • Be long-lasting and highly productive
Require less labour and lower veterinarian costs
To meet the expectations of dairy farmers practicing crossbreeding, the PCR favours bulls with superior skills on the following indexes: 

VikingRed breed:
Fat & Protein Production / Udder / A size avoiding small sizes / General health
Montbéliarde Coopex breed: 
Udder / A medium size avoiding tall sizes / A good temperament / Easy calving
VikingHolstein breed: 
Production / Easy calving / Hoof Health


How was the index created?

ProCROSS has conducted an international survey on dairy farmers who have been using ProCROSS for over 10 years. They described the type of cow they desired: medium size cows, with a good body condition, producing a high quantity of fat & protein and requiring the minimum labour and health treatments. This information is gathered in the PCR.

Why should I use the PCR index instead of ISU or NTM?

The PCR was specifically designed for the selection of VikingRed and Montbéliarde Coopex sires with qualities for dairy crossbreeding. The crossbreeding selection criteria are different from pure breeding selection criteria. This index is not intended to replace the pure breed index (VikingRed or Montbéliarde), but it makes it easier to identify the bulls recommended for crossbreeding.

How high is the PCR index of a bull well adapted to crossbreeding?

The expression of the PCR index is based on an average of 500 points, for the 2 index versions (PCRL and PCRs). The higher the PCR is, the more suitable the bull will be for crossbreeding.
