As the pastures green up and the days get longer, spring isn’t just a season of growth—it’s the prime window for advancing your herd’s genetic potential. At 605 Sires + Donors, we’re seeing a strong uptick in IVF demand, and for good reason. If you’re looking to hit fall and winter calving targets, now’s the time to get your donors on the schedule.
🕓 Spring Slots Fill Fast
From Colorado to Nebraska to right here in South Dakota, our partner satellite centers are booking out quickly. Whether you’re planning to work with Madison Genetics, Preferred Genetics, Nikkel Bros, or the Pratt Family, availability is limited—and our team is already seeing maxed-out weeks. Early booking means better options, more flexibility, and less stress.
🔬 IVF Efficiency at Its Peak
Spring conditions allow donors to thrive. With less stress from harsh weather, improved nutrition, and longer daylight hours, donor cows tend to respond better during this time of year. That translates to stronger oocyte yields, smoother aspirations, and more embryos per collection.
📈 Planning Ahead for Fall and Winter Calves
Embryos created this spring will directly impact your fall and winter calving schedules. For seedstock producers and competitive breeders, this is the time to build up a pipeline of elite calves that will hit the ground running when market attention peaks.
✅ Why 605?
With our on-site IVF lab in Marion, SD, reverse sorting capabilities, and streamlined scheduling through trusted satellite partners, we’re positioned to help you move quickly and confidently. Our team is ready to walk you through the process—whether it’s your first time or your fiftieth.
