Stgenetics Now Offers More Cells Per Straw
January 10, 2017

NAVASOTA, Texas — Livestock genetics innovator STgenetics™ has rolled out a new flagship A.I. product that packs twice the number of sex-sorted sperm cells per straw as its previous products,  leading to conception rates that are very close to those achieved using conventional semen.

Stgenetics Now Offers More Cells Per StrawHigh fertility SexedULTRA 4M™ sex sorted semen boasts 4 million cells per straw. Previous SexedULTRA™ semen straws contained 2.1 million cells per straw. During a field trial in Germany conducted by STgenetics in collaboration with German Genetics International, SexedULTRA 4M™ delivered conception rates comparable to  conventional semen packaged at a concentration of 15 million cells per straw over 7,500 inseminations.

“The increased conception rate of SexedULTRA 4M™ is due to improvements in sperm biotechnology, the media that nourishes and invigorates the sperm during the sorting process, and improved sorting machine technology,” said Dr. Vish Viswanath, leader of STgenetics’ Research and Development Team.

SexedULTRA 4M™ high fertility sex-sorted semen is even more effective when combined with genomic testing to ensure that producers get the most out of their mating plans. Genomic testing through a company like Genetic Visions-ST in Middleton, WI, allows producers to identify their highest genomic value animals and to evaluate in-depth their entire herds.

Creating a breeding plan around genomic testing and SexedULTRA 4M™ high fertility semen ensures that the best females in the herd deliver replacement heifers.
SexedULTRA 4M™ high fertility sex sorted semen is available on most of STgenetics’ elite dairy sires.
