At A Glance
Researchers at Colorado State University have developed a patented sensitive radioimmunoassay (RIA) for bovine and ovine interferon tau (IFNT) to determine pregnancy 14 days earlier than industry standard.
For more in-depth details, please contact our office.
Background
The current gold standard for determining pregnancy status in cattle is through rectal ultrasound on day 32 of predicted/possible pregnancy. By completing the patented RIA for IFNT on Day 18, accurately determining pregnancy status, it is possible to make re-breeding decisions for non-pregnant cows 14 days earlier – having great economic impact for dairy and beef cattle operations.
Benefits
- IFNT is only produced by the trophectoderm cells of the ruminant embryo
- Lack of detection of IFNT is key in managing ruminant reproductive cycles
