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
