Early pregnancy detection in Sheep is an important part of the production process in the pasture. Using an accurate, fast and easy pregnancy diagnosis method is the key to improve breeding efficiency and milk yield. Sheep Pregnancy Test Kit is a blood pregnancy test for dairy cows based on double antibody sandwich technology. It can be used to detect pregnancy-associated glycoprotein in serum/plasm/whole (EDTA or heparin sodium) samples of cows after 28 days post-breeding.
