To help dairy farmers select the best fitting A.I. bulls for their ProCROSS rotation program, the ProCROSS team has developed a new and user-friendly tool: ProCROSS Ranking (called PCR).
PCR is a practical selection tool that re-ranks bulls from their original pure breeding goal, ISU from France and NTM from Denmark, Finland and Sweden. PCR will help ProCROSS dairy farmers around the globe to make bull selection easier for their crossbreeding program.
PCR Overall breeding goal:
Breed an average-sized, long-lasting and high producing cow requiring less labor and veterinarian support.
PCR Solids & PCR Liquid
Due to variations in local milk payment policies, ProCROSS offers two options to choose between:
Focusing on bulls transmitting higher quantity of protein and fat.
|Focusing on bulls transmitting higher volume of liquid milk.|
All other traits are equally weighed in both PCR options.
PCR: greater emphasis on crossbreeding goals - what specific traits? How is it different from pure breeding?
Since ProCROSS is recognized as the leading 3-breed rotation system bringing economic gains through heterosis and breed
complementarities for Health, Fertility, Production and Survival, some important traits have been emphasized in PCR for mating
What is the validity of PCR as a sire selection tool? Who made it?
ProCROSS Ranking has been developed by breeding departments within VikingGenetics, supplier of VikingRed and VikingHolstein, and Coopex Montbeliarde, supplier of Montbeliarde bulls. This ranking classifies bulls in order to help mating ProCROSS cows. Because of its specific crossbreeding application, it does not represent a long term selection index within any of the 3 breeds of ProCROSS.
What Is PCR’S means of expression? Are the three breed PCR lists comparable?
PCR means of expression is based on an average of 500 unit points for both PCR Liquid and Solids, with the lowest at 400 and the highest slightly over 600 points. All three breeds have their own unique PCR, and therefore cannot be compared across breeds.
Where can I find PCR lists?
After each index run, ProCROSS Rankings (both Liquid and Solids) of all available Montbeliarde, VikingRed and VikingHolstein bulls will be updated. Please contact your local distributor for information on local PCR lists. Global list available on: here.
Main changes for VikingRed from NTM to PCR
Weight on production and udder have been increased: Targeting high levels of production.
Weight on frame has been increased: Assuring homogeneous size at herd level.
Weight on other diseases has been increased: VikingRed asset - highly correlated to longevity.
Weight on calving traits has been decreased: VikingRed asset, all VikingRed bulls excel at it.
Main changes for Coopex Montbeliarde from ISU to PCR
Weight on udder conformation has been increased: Handling high levels of production.
Weight on stature has been increased: Favoring medium size - Penalizing tall or small.
Weight on positive temperament and easier calving. Making cow & calf management easier.
Weight on fertility and rump have been slightly decreased: Montbeliarde breed strengths.
Main changes for VikingHolstein from NTM to PCR
Weight on production has been increased – Targeting high levels of production.
Weight on calving traits has been decreased – Both other breeds excel in maternal calving.
Weight on hoof health has been increased – More correlation of hoof health with longevity.
Weight on udder conformation has been slightly decreased – Breed strength, weight used in
other parts of the PCR.
