Keys to Success
Use of gender SELECTed semen will require a breeding gun designed to accommodate the smaller diameter .-cc straws. Straws are to be thawed and handled identical to their .-cc counterparts. However, the smaller diameter and compromised semen quality will make them much more sensitive to cold shock and errors in semen handling. To maximize potential for success:

 Thaw straws in 95 degree 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 highly experienced technicians 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.
