Early diagnosis of pregnancy is of great importance in modern animal industry due to the high cost of feed and labor. Especially after artificial insemination is widely used, the earlier the pregnancy is determined, the earlier feeding plans will be performed. The general methodology to determine pig pregnancy is by observation or B-mode ultrasound scanners, either of which is not quite economic in small or middle size farms.
The current rapid test kit utilizes the high affinity of monoclonal antibody against an estrogen marker in pigs, which can easily identify the concentration and presence of it. If the concentration is above certain number, the pig will be pregnant and if not, the pig will not be pregnant. Further measurement such as mating or AI shall be performed.
This kit shall be used to test pig urine, which shall be collected within 23 to 32 days after mating or insemination.
