ACC-SS®
What is ACC-SS
ACC-SS is sexed semen, available from Accerated Genetics, that can help you get
more heifer calves.
ACC-SS should be used on virgin heifers and is not recommended for use on lactating cows. ACC-SS Sexed Semen is available for both dairy and beef cattle and is also available in TOP GENETIC SIRES!
How is ACC-SS made?
ACC-SS sexed semen is processed using flow cytometry to sort the female/X chromosome-bearing sperm cells from the male/Y chromosome-bearing sperm cells.

Why should I use ACC-SS sexed semen?
When used properly in well-managed herds, ACC-SS sexed semen can produce more heifer calves for your dairy or beef operation. This allows you to increase your herd size from within, avoiding the high cost of replacement heifers and the risk of disease when bringing in heifers from other operations.
What is the female gender ratio for ACC-SS sexed semen?
Research has shown that the conception rate of sexed semen in virgin heifers is 35 to 40 percent versus 55 to 60 percent using conventional semen. Because of the lower conception rates, ACC-SS is not recommended for use on lactating cows.
For best results, only inseminate heifers that are in standing heat. ACC-SS is not recommended for use with synchronization programs.
What is the proper way to handle ACC-SS sexed semen straws?
Working with sexed semen is similar to working with conventional semen. However, because 1/4-cc sexed semen straws contain fewer sperm cells than 1/2-cc straws of conventional semen and the vitality of the semen is somewhat compromised in the sorting process, extra precaution should be taken to ensure an optimum conception rate.

ACC-SS should only be used for a single-use artificial insemination of bovine heifers
who are not part of a timed A.I. or synchronization program or being flushed for
embryo transfer. For optimum results, use only by those highly experienced in A.I.
technique. ACC-SS is subject to availability. Accelerated Genetics, or its agents,
will not make any guarantee or warranty on conception rates and/or gender ratio.

Recommendations for a successful insemination:
ACC-SS sexed semen is only available in 1/4-cc straws and must be used with an insemination gun designed to accommodate the smaller straws.
Because of the smaller straw size, sexed semen straws are more sensitive to cold shock and errors in semen handling.
To help acheive the highest success rates possible:
- Use only in healthy, virgin heifers that have been observed in standing heat.
- Inseminate 8-12 hours after the first detected mounting.
- Use only an experienced A.I. technician, and never split straws.
- Always use tweezers, never use fingers, to handle straws.
- Remove the selected straw from the canister as quickly as possible. Minimize the container's time above the liquid nitrogen.
- Return the canister to the liquid nitrogen promptly, keeping it out no more than five (5) seconds.
- Ensure that semen is stored at the proper temperature.
- Thaw straws in 95°F water for at least 45 seconds.
- Pre-warm the A.I. gun and sheath to avoid cold shock, and thoroughly dry the straw before inserting it into the gun.
- Deposit semen in the uterine body just past the opening of the cervix, just like conventional semen.
