STgenetics® at ADSA

Six scientists from STg® will give presentations on the company’s cutting-edge and research during ADSA® Annual Meeting June 23-26 in Cincinnati, Ohio

Six scientists from global livestock reproductive services leader and innovator STgenetics® (STg®) will give presentations on the company’s cutting-edge and revolutionary research during American Dairy Science Association® (ADSA®) Annual Meeting June 23-26 in Cincinnati, Ohio.

The ADSA characterizes the gathering as “the most comprehensive dairy science meeting in the world. As a global forum for professionals, educators, and students, the meeting will attract more than 1,700 dairy foods and production specialists from 51 countries with common but diverse interests in the future of dairy science.”

STg® scientists will share with colleagues their latest ground-breaking research into the semen sorting process and sex-sorted semen, dairy cattle feed efficiency, genomic selection and dairy cattle mating.

STg® has pioneered research on improving sex-sorted semen from dairy sires since the company was granted a license in 2003 to use the flow cytometric process developed by the federal government. Company management has invested significant financial and manpower resources into research and development aimed at continually improving semen sorting technology and providing customers with the best and most advanced product on the market. This dedication to technological innovation resulted in development of the revolutionary SexedULTRA® semen sorting process and SexedULTRA 4M® high-fertility sex-sorted semen, which achieves conception rates comparable to conventional semen.

As part of its business philosophy of challenging the livestock industry’s technological status quo through innovative science, the company has greatly expanded its research scope to embrace a more holistic approach to animal production, including genetics, reproduction, physiology, endocrinology and nutrition.

Last year’s ADSA® meeting attracted participants from 44 U.S. states and territories and 51 countries. These participants represented 839 universities, 612 companies, 72 government agencies, 19 associations and 133 other organizations.
