Running Pregnant Donors: What Livestock Producers Should Know

It’s a common misconception in the livestock industry: once a donor is bred, her work is done. But with the right management, pregnant donors can continue to play a powerful role in your IVF embryo program.

At Trans Ova Genetics, our team works with clients across the country to safely and effectively aspirate pregnant donors. Here’s what you should know about the benefits, timing, and considerations.

🧬 Why Consider Running a Pregnant Donor?

Maximize your genetic investment

Donors that are already confirmed bred can continue to produce embryos, helping you extend the value of elite females without waiting for a new breeding window.

Strategic breeding plans

Running a pregnant donor can allow you to plan for both current pregnancies and future matings—making your donor program more efficient and forward-focused.

Stay on schedule and get more embryos

For many breeders, maintaining a tight calving window is non-negotiable. Running pregnant donors allows you to stick to your ideal calving timeline while still creating more embryos than a traditional breeding cycle would allow.

By aspirating donors during safe stages of pregnancy, you don’t have to choose between advancing your genetics and staying on schedule—you can do both. It’s a powerful way to increase output without extending your calving season or overhauling your management plan.

🔍 How It Works

Our team assesses each donor individually to determine the safest stage of pregnancy for aspiration, usually focusing on early to mid-gestation. With careful management and expert oversight, the process is designed to protect both the pregnancy and the donor’s overall health and productivity.
