About ruminant pregnancy

Establish a protocol for reproductive efficiency with Alertys Pregnancy Tests.

  • Work together. Reproductive efficiency improves when producers, veterinarians, and laboratories work together to identify open animals early.
  • Trust the science. Alertys pregnancy tests detect a highly specific marker of pregnancy: pregnancy-associated glycoproteins (PAGs). Unlike progesterone levels that fluctuate naturally during a cycle, PAGs are only produced in the presence of an embryo or foetus.
  • Depend on accurate results. Use Alertys pregnancy tests to help guide veterinary recommendations for animal health and productivity.
