At North East genetics we have become industry leaders in the use of Fresh Sexed semen in large synchronised Artificial Insemination programs for heifers and cows. When fresh sexed semen is used, the results are better for farmers than frozen sexed semen. We have used it in heifers in a FTAI (fixed time artificial insemination) program and in cows, and it produces better results.
Fresh sexed semen gives consistently higher conception rates then frozen sexed because the semen is not damaged by the freeze/thaw process. Frozen sexed semen can be a compromised product that yields variable conception rate results.
Sexed semen insemination needs to be done correctly to increase chances of getting more animals pregnant. Due to the decrease in fertility of sexed semen, it is vitally important that animal selection and management, and semen handling and insemination are the best they can be.
Individual conception rates for fresh sexed semen in dairy heifers show that conception rates of up to 70 per cent are achievable, but 55 per cent was the overall average. This compares to a 40 per cent conception rate with frozen sexed semen.
