Frequently Asked Questions (FAQ)
Can genomic breeding values be calculated for all breeds?
Currently in Switzerland genomic breeding values are only calculated for the Braunvieh (inc. Original Braunvieh), Simmental, Swiss Fleckvieh and Holstein (red and black) and these only for herd book animals. There are no genomic breeding values available in Switzerland for other dairy and beef breeds. However, Mutterkuh Schweiz is currently developing genomic selection for the Limousin breed.
When can I have my animal examined?
Examinations are offered by the three big Swiss cattle breeding associations (Braunvieh Schweiz, swissherdbook and Holstein Breeding Association). You can find the details including electronic order placement on their websites www.braunvieh.ch, www.swissherdbook.ch or www.holstein.ch.
How much does an examination cost?
The costs of an examination are comprised of the laboratory cost and the price for calculating the genomic breeding values. Genotyping with the cheaper LD-chip suffices for normal applications. Added to this are the costs for any potential extra tests. Please consult the website of the relevant breeding organisation for current prices. Breeding organisations sometimes also offer price reductions.
What is required for a laboratory examination?
Essentially blood, semen and also hair roots are suitable for determining SNP. Hair roots are now also particularly recommended for twins. In all cases you must follow the notification from your breeding association on how to proceed. A careful sample extraction is hugely important for success. For example, hair root samples are to be taken with the Geneseek hair card.
In what format will I receive the results?
From all breeding associations you will receive a genomic optimized breeding value (GOBV) for (virtually) all traits. These have been official since December 2010 and they replace the traditional breeding values.
How long will it take for me to receive the results?
The samples are shipped according to the instructions of the breeding organisations to Qualitas AG in Zug. From there they are forwarded twice a month – as a rule on the first and third Tuesday of the month – to the laboratory. Normally the genomic breeding values are available 30 - 50 days after sending in the sample. The results are delivered to you in writing by your association.
Are the genomic breeding values stated in official documents?
The genomic optimized breeding values (GOBV) have been official since December 2010 and they replace traditional breeding values. They are identified in Switzerland as follows:
- GA: Direct genomic breeding value (DGV) combined with the traditional lineage breeding value.
- G: DGV combined with the Swiss progeny testing result
- GI: DGV combined with the Interbull breeding value
Do direct genomic breeding values change?
Yes, they can change. Although laboratory values (SNP genotypes) are fixed, the estimated equations with which the genomic breeding values are calculated from the laboratory values are regularly updated.
Will there continue to be progeny testing?
For the moment progeny testing in Switzerland is not for discussion. There will also be a need in the future for a type of verification due to progeny yields.
