- More than 750,000 registered Fleckvieh and more than 130,000 registered Brown Swiss cows
- Largest Holstein breeding population worldwide
- Largest Red Holstein breeding population worldwide
- Largest Fleckvieh breeding population worldwide
- Largest Brown Swiss breeding population worldwide
- Proven cow families having deep pedigrees
- Lots of different bloodlines
- One of the oldest Holstein herd books in the world (1878) including overall data of more than 7,000,000 cattle
- National and international breeding programs
- The largest and most versatile reference samples in the world
- The reference sample for Holstein and Red Holstein alone is composed of more than 38,000 reliable daughter proven sires and 150,000 cows
- Worldwide accepted estimation formula for the calculation of genomic breeding values with successful practice validation
- Very strong selection intensity among a total of more than 10,000 genotyped young bulls per year
2. Balanced breeding goal for Holsteins
Milk production with excellent components
at least 10,000 kg milk; 4.0 % fat; 3.5 % protein
Optimum ranking of A.I. bulls according to the Total Merit Index (RZG)
The RZG considers milk production and functional traits corresponding to their economic importance.
3. Reliable data and breeding values
High accuracy of identification and herd test
All animals of a herd, with no exception, get a cattle ID right after birth and are registered centrally. Government-controlled and independent herd testing organizations as well as an independent data collection centre, guarantee the correct data collection and breeding values.
Ideal test conditions for daughter proofs
Test bull daughters are kept under various housing and management conditions on family farms as well as on large commercial operations with more than 1,000 dairy cows. This guarantees comparable and reliable data material.
Leading classical breeding values
The independent data centre (vit) set milestones in genetic evaluations. Germany has introduced the test-day-model, being the first country worldwide. Furthermore, Germany was first in evaluating all economically important functional traits based on complete data. The composition of the German total merit index (RZG) set international standards for modern dairy cattle breeding.
Reliable genomic breeding values
Germany is the leading country in genomics. German genomics are based on the largest available training set (reference population). Germany was the first to use trait different polygenic effects. Together with unbiased sire-pedigree information instead of full parent averages, German genomic enhanced breeding values are more realistic.
