1. Timing
Efficient utilization of a canine progesterone assay necessitates exact timing relative to the bitch’s estrous cycle. The temporal relationship between progesterone ranges and ovulation is essential; a basal progesterone stage usually precedes the luteinizing hormone (LH) surge, which in flip precedes ovulation by roughly 48 hours. Serial progesterone testing is usually required to precisely pinpoint the preovulatory rise. Initiating assessments too early within the cycle wastes sources and might yield deceptive info, whereas commencing too late dangers lacking the optimum breeding window.
For instance, a breeder aiming for transcervical insemination requires exceptionally correct timing. Semen lifespan following this process is comparatively quick, necessitating insemination as near ovulation as doable. Constant, sequential progesterone measurements, typically initiated when vulvar swelling and discharge are noticed, allow veterinarians to foretell ovulation with larger precision. An preliminary check displaying a progesterone stage beneath 2 ng/mL would possibly immediate every day testing, whereas a studying between 2 and 5 ng/mL typically signifies that ovulation will happen inside the subsequent 24-48 hours.
