Alertys OnFarm Pregnancy Test

Pregnancy testing run by farmers earlier, reliably and on your schedule!

When a cow becomes pregnant she produces pregnancy-associated glycoproteins (PAGs). These PAGs are only produced in the presence of a live embryo of fetus.

The Alertys OnFarm Pregnancy Test detects (PAGs) in whole blood (EDTA) as early as 28 days post-breeding and 60 days post-calving.

How the test works

The test detects highly specific markers of pregnancy in blood, serum and/or plasma: pregnancy-associated glycoproteins (PAGS). Unlike progesterone levels that fluctuate naturally during a cycle, PAGs are only produced in the presence of a live embryo or fetus.
