SiryX Sexed Semen

Product benefits

  • More heifers
  • Greater value replacements
  • Easier calving

With SiryX sexed semen you can increase the number of heifers generated through your yearly mating programme. SiryX sexed semen goes through a sorting process where more than 90% of the sperm cells in the straw carry the female ‘X’
chromosome and only less than 10% of the sperm carry the male ‘Y’ chromosome*. This ratio carries through to produce on average 90% heifers from the doses of sexed semen used on the farm.

Conception rates with SiryX are around 10-15% lower than non-sexed semen. Using the correct semen handling and the right selection of animals on heat will help you get the best possible results using the SiryX sexed semen product.

* As outlined in the quality control threshold as provided by Sexing Technologies in their sorting labs.
