More heifers, more possibilities
Select Sires was the first major A.I. company to offer sexed semen and continues to lead the way with the industry’s largest production capacity. Nearing the production of the 1.5 millionth straw of sexed semen, Select Sires has the experience and expertise that guarantees the highest quality product for your breeding program.
- Most other companies marketing sexed semen today did little or no research. Knowledge from Select’s research, which took place both in the lab and on the farm, has been used to maximize the quality and fertility of each sire chosen to be sexed.
- At Select’s Ohio facility, a large battery of gender SELECTed sires allows highly trained sexing technicians the opportunity to pick and choose those with only the highest quality sperm cells for processing during each collection period. It’s this insurance policy that guarantees only the best possible product will be used on your heifers.
- Only Select Sires’ highest ranking bulls for fertility, based on conventional semen conception data, are even considered as candidates for the gender SELECTed program. Select realizes that not every bull can meet the stringent semen quality criteria necessary to provide the fertility results that you expect from a sexed product.

To maximize potential for success:
- Thaw straws in 95°F water bath for 45 seconds.
- Semen thawing and handling environments should be warm and draft free.
- Warm all semen handling equipment including guns, sheaths and paper towels prior to contacting straws.
- Only people highly skilled in A.I. should use this product.
- Use only in well-managed, virgin heifers that have achieved greater than 60 percent of their mature weight by 14 months and are in moderate or better body condition.
- Inseminate heifers eight to 12 hours after observed estrus (AM/PM Rule). Once-a-day A.I. programs are not conducive to optimum results.
- Use of estrus synchronization and breeding to observed estrus is encouraged, but use of timed-A.I. in the absence of observed estrus is discouraged.
Use of gender SELECTed semen will require a breeding gun designed to accommodate the ¼-cc straws. Straws are to be thawed and handled identical to their ½-cc counterparts. However, the smaller diameter and compromised semen quality will make them much more sensitive to cold shock and errors in semen handling.
