How many days can pregnancy be detected by palpation?

Pregnancy can typically be detected by palpation at around 28 to 30 days after breeding in dairy cattle. During this time, the uterus begins to change in size and shape as it accommodates the developing embryo. Experienced veterinarians or cattle handlers can utilize these changes to identify pregnancy.

At 28 to 30 days, early signs such as alterations in the tone of the uterus and the presence of a vesicle can be felt, making it a reliable timeframe for detecting pregnancy through rectal palpation. This method is crucial for managing breeding programs, ensuring efficient reproduction, and enhancing overall herd productivity.

In contrast, earlier detection at 10 to 14 days is generally not feasible, as the embryo is still very small and embedded, making it difficult to discern. Similarly, while pregnancy can be confirmed at later stages (like 35-40 days or 50-55 days), the 28 to 30-day window is considered the standard period for reliable detection through palpation.
