Genomics and Quality Control: The German Breeding Model as a Risk Management System

Genomics: Breeding Without Waiting for Generations

The key point of the presentation was the assertion that modern breeding no longer relies on the classical 'daughter assessment' model. Genomic evaluation allows decisions to be made before offspring appear.

This principle is based on comparing an animal's genetic profile (SNP analysis) with a vast array of accumulated data, enabling precise evaluation of bulls without their own productivity or daughters.

This radically changes the speed of breeding: from a multi-year cycle to operational management decisions.

Scale as a Condition for Accuracy

However, as the speaker emphasized, genomic evaluation requires a large database. Practice has shown that even developed countries cannot rely on just a few thousand tested bulls.

According to the data presented in the report:

• 1–5 thousand bulls do not provide reliable results
• only with a base of over 10 thousand animals is a high accuracy of evaluation achieved

This is why international cooperation becomes a key factor. In Europe, this function is performed by associations like EuroGenomics, which combines data from Germany, France, the Netherlands, and Scandinavian countries.

From Productivity to a Comprehensive Index

Alex Bauer paid special attention to the evolution of breeding indices. Previously, productivity was the key indicator, but today a comprehensive evaluation system is used.

The structure of modern indices includes:

• productivity;
• exterior;
• health (including somatic cells);
• longevity of use;
• fertility.

Genetic Risks: Management Instead of Ignoring

Alex Bauer specifically addressed the topic of genetic anomalies. In modern breeding programs, their consideration has become a mandatory element.

The practice includes:

• identifying carriers of genetic defects;
• excluding them from breeding programs;
• controlled crossbreeding with subsequent culling.

Semen Control: Standardization as the Market Basis

The quality of semen is a critical element of the entire breeding system, emphasized the speaker.

The German model involves strict standardization:

• 16–20 million sperm cells per dose;
• mobility control before and after freezing;
• regular laboratory tests;
• independent quality audits.

All stages—from bull quarantine to export—are under veterinary control.

Digitalization and AI: The Next Development Stage

The expert presented the AI STATION system, which uses artificial intelligence for semen analysis. It allows for automatic determination of mobility and concentration; detecting anomalies without staining; reducing human factor influence; standardizing analysis results.

In the future, such solutions may predict: semen fertility; embryo quality; herd reproductive performance.
