Guidelines for using sexed semen

†Restrict sexed semen use to 1st or 2nd services when usingon heifers and 1st service when using on lactating cows.


†Fertility window for sexed semen is narrower because thesperm are believed to be closer in their timing for optimalfertility. Therefore, it is recommended to breed at peak signsof heat. This may result in a delay in the time of breedingby 4-8 hours compared to best practices when usingconventional semen.


†Use on heifers with the appropriate weight, height and bodycondition.


†Use on heifers that are at the age (or younger) thattranslates to your targeted age at first calving.


†Try to breed heifers off natural heats (sync programs may beless reliable for heifers).


†When using sexed semen on lactating cows, select higherfertility cows that are healthy with good body condition.


†Sexed semen works well in combination with Semexai24â"/Heatime® or other activity monitoring system.


†Many Jersey breeders opt to use sexed semen on their cowsas a regular practice since Jerseys have high fertility and bullcalves have a low value.
