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.
High 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 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.
