Unlocking the Secrets of Canine Reproduction with Progesterone Analysis

As a breeder, you're well aware of the unique intricacies of canine reproduction. Delving into the world of progesterone analysis can significantly enhance your breeding success. Here, we recap the essential insights and share the invaluable role of the Vet Chroma Progesterone Analyzer throughout this journey.

Understanding the Significance of Progesterone Progesterone, secreted before ovulation in dogs, holds the key to precise breeding timing. Timing is everything, and mistimed breeding remains a leading cause of infertility in bitches. Our journey begins with this fundamental understanding.

Commencing the Progesterone Journey The journey starts approximately six days into the heat cycle, as early detection is pivotal. Progesterone results can be expressed in two units: ng/mL and nmol/L. Accurate interpretation hinges on recognizing the unit used.

The Importance of Serial Testing Determining ovulation based on a single test is often impossible. Multiple tests, typically three or four, over several days are essential for accuracy. Unlike LH assays requiring daily monitoring, progesterone rises progressively during estrus.

The Basal Progesterone Phase Understanding basal progesterone levels (below 1ng/mL) helps establish appropriate retest intervals. The Vet Chroma aids in distinguishing this phase.

Crucial Milestones: LH Peak and Ovulation Timing ovulation revolves around the LH peak and ovulation. LH peaks when progesterone reaches 2-3ng/mL, followed by ovulation two to three days later.

Continuing Beyond LH Peak Continuous monitoring is essential even after the LH peak, as some bitches may experience anovulatory cycles—cycles without ovulation.

The Mystery of Anovulatory Cycles Anovulatory cycles, where follicles fail to release eggs, can occur. Progesterone may rise and then suddenly drop, leading to non-ovulation.

The Progesterone Threshold for Ovulation Ovulation typically occurs at progesterone levels of 5-6ng/mL, consistent across dog breeds and sizes. Vet Chroma's precision ensures accurate readings.

The Myth of an Ideal Progesterone Level There's no "ideal" progesterone level for breeding. Fertility can be optimal with progesterone values varying widely. Timing is essential, not a specific progesterone value.

Post-Ovulation Progesterone Monitoring Post-ovulation, progesterone levels rise quickly. Confirming this rise is crucial, as a plateau may indicate issues like ovarian cysts.

Vet Chroma and the World of Progesterone Testing Progesterone testing machines, including the Vet Chroma, are primarily developed for humans but effectively used for canines. The key lies in proper interpretation by experts familiar with the specific laboratory or machine.

In-House Progesterone Machines Veterinary clinics now have in-house machines like the Vet Chroma, making progesterone analysis more accessible. These machines provide results in just 18-20 minutes.

Cycle Variability Expect up to 40% variations between cycles. Timing of ovulation should be performed diligently with each cycle.

As we navigate the complexities of canine reproduction, the Vet Chroma Progesterone Analyzer stands as a trusted companion, providing accurate insights to enhance breeding success. With a deep understanding of progesterone analysis, breeders can make informed decisions, ensuring healthy litters and the continuation of their breeding legacy.
