Canine Birth and C-Section Timing

Predicting Ovulation is done by accurately detecting the initial rise in progesterone. Ovulation usually occurs 2 days after the initial rise in progesterone. The most fertile time to breed is 2 to 4 days after ovulation.

To time c-section or whelping, test progesterone starting 58 – 60 days after first breeding (average gestation 63 days). A drop in progesterone to < 2 ng/mL indicates whelping will occur within 24 – 36 hours.

Why C-Section Timing is Important

Determination of progesterone is very important in the Canine reproductive cycle in deciding when to breed or when to do a C-section.

Canine cycles are variable, progesterone can rise slowly or very quickly (weekends & holidays included). Progesterone often varies from one cycle to the next and physical signs can be misleading.

Because of the importance of knowing and planning action based on progesterone level information, the delay in getting laboratory results is best avoided. Also, doing some testing at home is less stressful to the animal and its owner.

How it Works

The concentration of progesterone in the fresh sample is related to the color intensity of the Test Line. All the reagents are immobilized on the cassette and only Sample is added to get the result.

Because progesterone concentration is very low (parts per billion) (ng/ml), an optical Reader is required to convert the line intensities to concentration numbers.

The Cube Reader digitizes the line intensities and accurately calculates the progesterone concentration based on a standard curve programmed for the Lot. For every production Lot of test cassettes, multiple samples are tested and a standard curve is determined and stored on a Memory card.
