Holstein Index April 2015

Upheavals in indexing, for reliability and international harmonization.

The indexing of April 2015 is a special output for more than one reason. As usual, this first release is the major of the year because it allows the selection of new bulls for the next insemination campaign. This output of April includes several key events:

  • the change in genomic evaluation method :
    • increase of the numbers of QTL per trait (the average, going from 500 to 3000)
    • consideration of the genomic relationship for an increase of the reliability resulting in higher CDs, this allows to approach foreign models that use a genomic ancestry in calculating their index.
  • The increase of the size of the reference population to reach 30 000 bulls, making the largest population in the world.
  • Integrate the change of base (less 4.5 points of ISU).
  • the integration of the individual performances of genotyped females in their index.

Unlike the previous model, the genomic index of a female will be amended during its lactations. This method called "blending" includes the performances (production and scrutiny) to be closer to the real qualities of the animal. These variations also contribute to changes in the index of genotyped females.

These changes in the genomic calculation, resulting in more or less important male and female index variations, that disadvantage the breeders and selection companies, now allow more accuracy and reliability.

We could not expect to get more details and a better correlation with foreign assessments, without accepting some changes in the rankings.

From our side, we find this output of April more coherent and especially better correlated with other indexing systems internationally. Genes Diffusion is satisfied to have always kept the same strategy in its breeding objectives. To know:

  • the balance between production type and fitness traits, in order to create profitable and sustainable animals.
  • to have maintained international opening for genetic sourcing.
  • to prioritize the best pedigrees and best cow families, not only to be blinded by the numbers.
  • to have developed strong partnerships with breeders sharing the same philosophy.

The following statistics illustrate the excellent performance of the Genes Diffusion program, following the latest French Genomics ranking:

  • Top 10 French ISU : 42% for Genes Diffusion (5 bulls out of 12) including IPNOS, n°3 ISU, n°2 INEL and n°3 for the French Milk index, available soon in sexed semen.
  • 35 French bulls over 190 points of ISU : 43% for Genes Diffusion
  • 43% for Genes Diffusion : 39% for Genes Diffusion
  • Top 10 Type : 80% for Genes Diffusion including the 5 best ones with FRIST PJP as the first of them (+4,6)
  • 7 French bulls over or equal to 3.5 in Udders : 100% for Genes Diffusion
  • 10 French bulls over +2 in Feet and Legs : 7 for Genes Diffusion including the 4 best French bulls
  • 39 French bulls over 2.5 in Udders : 16 for Genes Diffusion with, as the French leader, JULLIUS (DOORMAN x NIAGRA), French n°1 at 4.2
  • 51 French bulls over +2 in Fertility : 26 for Genes Diffusion with, as the French leader, ASTOR (LATIMER x DORCY), +3.1 in Fertility

About new bulls :

IPNOS, in 3rd position of the ranking

At the 3rd position of the ranking with ISU 205, IPNOS comes from a purchase in Germany. Son of SHOTGLASS x SCALONI (son of Shottle) x BILLION, he confirms his indexes and progresses despite the change of base.
It appears as one of the most dairy French bulls with a Milk index of +2040 without damaging the protein and extremely healthy improver. His daughters have very functional Type with teats suitable for robot milking.
They also have very good feet and legs with hoof health above the average.
IPNOS is a bull perfectly suitable for the industrial dairy farming. He started as a Sire of Sons in our scheme and will soon be available in our sexed range.

IBERIK EBA, top level and ease of use

Born in the farming partner of GAEC Brilland (72), IBERIK EBA is an attractive bull because of his pedigree that brings originality and makes his use very easy.
