FALL WEANED CALF PROGRAM

WHAT IS THE FALL WEANED CALF PROGRAM?

After implanting your embryos, recipient cows are preg-checked safe prior to getting turned out for the winter. We begin calving at RVS August 15th – October 31st annually. Calves are fully vaccinated and reared until six months of age or ready to be weaned.

How many days postpartum do I have to wait to flush my donor?

Donor should be a minimum of 60 days postpartum on flush day. Cows should have received all pre breeding vaccinations a minimum of 30 days prior to collection. All donor animals should be on a rising plane of nutrition in the postpartum period.
How often can my donor be flushed?

Donors can be flushed every 30-35 depending on their post flush heat, however if time is not a factor we will typically schedule donors every 45 days.
How many embryos on average do you get from conventional flushing?

In our facility we are averaging 6.4 grade 1 freezable quality embryos per beef donor. Results can vary depending on individual cows performance ability as some cows may give zero freezable embryos, and our current record is 42 Grade 1 freezable.
