seleXYon (Accordion EN)
The optimum use of seleXYon is in the combination of “X” and “Y”, therefore in the use of both products. Today seleXYon forms part of the company strategy for many cattle breeding operations – and this has produced the corresponding financial success. This means seleXYon – female and male – is scheduled on the basis of the selected breeding strategy and consistently deployed.

Company strategy
Do not leave your decisions to chance
Whether the next generation is male or female can have significant financial implications. And female offspring can be worth their weight in gold for restocking. With seleXYon forming part of the company strategy the farm manager decides on the value of a calf and on the “gold” in the restocking process and no longer leaves anything to chance. With its broad offering, a high non-return rate and an attractive price offer, SeleXYon has 3 success factors.
Broad offering
- One will certainly be suitable: The broad offering of seleXYon bulls will do justice to every breeding objective and every animal in the shed.
- Market-aligned production: The sexing laboratory at the production station in Mülligen ensures short processes between semen extraction and sexing. This enables a production of seleXYon doses that is largely adapted to market dynamics.
High non-return rate
Good fertilisation capacity: The non-return rate of seleXYon doses is only a little below those of normal semen doses. This enables a broad application in the herd and even more company success. Even better thanks to progress: The continuous further developments in separation technologies are pointing to an even better fertilisation capacity. The future of seleXYon is therefore promising ever greater success.
Attractive price
Early price reduction: Through the production of seleXYon in its own laboratory, Swissgenetics has fulfilled two needs with one deed: A Swiss product and cost-effective production. Even before the start of production Swissgenetics had reduced the prices of seleXYon by up to 20%. A small gift to its loyal customer-base. Continued attractive prices: If the success of seleXYon continues in the same way, Swissgenetics will be able to keep prices stable, and in a best case scenario, even reduce them further. It is certain that the price for seleXYon will always be fair and attractive.
More success
The successful trio: Thanks to the success-promising trio of “broad offering”, “high NRR” and “attractive price” seleXYon is making a considerable contribution to the company’s success. And this becomes even more certain when seleXYon is used as part of company strategy. Keep control: Chance is a poor adviser for success. The best adviser is the farm manager by using seleXYon. He is the one who decides on the breeding success.

Semen sexing
How does semen sexing work?
Whether a cow calf or bull calf is created is decided in the fertilisation when an X-chromosome is added to a sperm (produces a cow calf) or a Y-chromosome is added (produces a bull calf). The objective is to enrich the sperms with the desired sex chromosomes (X or Y) and to remove the others, or at least to impede them.
The principle of semen sexing
A new generation sorter (of which there are 4 in Mülligen), can produce approximately 10 sexed semen doses per hour each with about 2 million sperm. To date it has not been possible to significantly increase the performance of the sorter. On the other hand, a reliable enrichment of X-sperm to over 90% has been achieved with this method.
Terms
Chromosome
Structure in the cell nucleus that contains the genetic substance (DNA). Chromosomes occur in pairs apart from in gametes and originate half from the father and half from the mother. In cattle there are a further 2 x 29 normal chromosomes in addition to the two sex chromosomes X and Y.
Female animals receive two X chromosomes and male animals receive one X and one Y chromosome in their cells.
DNA
Abbreviation of the term DesoxyriboNucleic Acid.
A thread-like molecule in the cell nucleus in the form of a double-strand.
DNA contains the genetic code.
Flow cytometry
Procedure for counting, examining and sorting cells and other microscopic particles in a liquid flow. The particles are marked here with a fluorescent dye.
Sex percentages
A promise is a promise
“Anyone inseminating with seleXYon will on average receive the desired sex at least nine times out of ten births.” This guarantee has applied since sexed semen doses have been used at Swissgenetics.
We verify this promise every year. All calves born from SeleXYon fertilisation are assessed via the calf notifications to the Swiss stock movement database (TVD)
The result from the previous year of 2019 shows that 91.3% of these calves had the desired sex. However, the residual risk of a calf being born with the “wrong” sex must continue to be expected.
In 2021 an average of 7.9% of calves were born with the wrong sex.
Birth notifications from the calendar year 2021
The figures once again show that the consistent utilisation of seleXYon as part of company strategy is worthwhile. Genetic progress through targeted progeny can be both increased and also accelerated in this manner.
