From production to sorting, processing, shipment, insemination and reproduction performance in the field - we follow the performance closely and adjust whenever needed.

The production of sexed semen happens at the VikingGenetics bull station in Denmark. The lab is next door to the barn, which allows our staff to perform the highest quality control.

Our lab performs a wide range of semen quality analyses for each batch produced with the goal of providing you with the semen dose with optimal field performance. Some analyses that we perform:

  • progressive and total motility
  • concentration
  • vitality
  • morphology

For evaluations we use the newest technologies such as flow cytometers (concentration and viability) and CASA technology (progressive and total motility). Only the best doses fulfilling strict quality criteria are released for distribution.

Unique quality standards

Our quality standards were set as a result of one of the largest insemination trials in the world, where semen quality parameters were correlated to field fertility results obtained from nearly 200,000 inseminations.

With X-Vik sexed semen you ensure the best reproduction performance in your herd.

Solutions and tools to support you

Rearing too many replacement heifers can be costly. On the other hand, using too much beef semen can also cause problems, as you risk lacking replacement heifers to sustain the herd.
