Sexed semen
Every time a cow calves you’ll have to wait and see whether it is a heifer calf, or yet another bull calf. Usually there is a 50:50 chance of either a heifer or a bull. Sexed semen offers dairy farmers across the world the opportunity to breed offspring from cows and heifers that offer the highest genetic gain.
CRV has an extensive range of top bulls and options with sexed semen (SiryX). We also help you with your breeding strategy and we identify hidden returns from your herd. In this way we help you to get more profit from your herd.
What is SiryX?
SiryX is sexed semen produced in special laboratories in the Netherlands, Brazil and the USA. Inseminations with SiryX semen will result in 90%, or more, heifer calves.
CRV is using the most advanced and developed techniques available at the moment and the operators responsible for the production of SiryX have had specialist training in the USA.
SiryX has advantages for dairy farmers and has the capacity to maximize farm profit in several ways:
- Assured production of heifer calves for
replacement or expansion - Reducing the number of difficult births
- Higher turnover
- Faster genetic progress
