Testing time: 
25 days later after swine gets breeded, users can use  Pregnancy Test Instrument to test. Clinical trial proves that testing is 99% accurate 30 days after breeding. At 65 to 70 days after breeding the litter displaces the fluid and the testing accuracy decreases. In order to get accurate test, you need to place the probe on the proper testing spot with suitable skin touch and proper direction at the right time.
