Abstract A haemagglutination inhibition assay for measuring eCG (Equine Chorionic Gonadotrophin) in pregnant mare serum has been standardized to detect pregnancy in mares at an early stage. A polyclonal antiserum against eCG was raised in rabbit. The eCG was detected in the serum at 45 days of gestation which rose sharply to reach maximum level around 82 days of gestation and declined afterwards. The results were found to be more accurate and precise than to those obtained by bioassay in immature female mice by injecting serum from pregnant mares and calculating ovarian weight gain. Top Key words haemagglutination inhibition, Equine Chorionic Gonadotrophin, pregnancy detection. Top |
