Common Questions

Question: Is Jared a veterinarian?
Answer: No, he is a Reproductive Physiologist

Jared obtained a BS in Animal Science and went on to get a MS in Animal Reproduction. An official term for him would be Reproductive Physiologist. His highly specific skill set has allowed him to help his clients capitalize on growing and implementing the highest and best genetics into their herds. He does enjoy a close relationship with local vets, and has even trained and done embryo work for some.

Question: How Many Embryos come out of a flush?
Answer: The average is about 6-8

Although the number of retrieved embryos varies greatly, on average you can expect about 6-8 embryos per cow per flush. The spectrum for retrieval is as great as it is for the expressed characteristics of an individual cow. There are times where there are no viable embryos retrieved, and there are other times that 40-50 have been retrieved. It all is all up to her and how she is managed. Retrieval varies on the animal's genetics, reproductive status, nutrition, response to fertility drugs and even the weather. Sometimes increasing or decreasing doses of the fertility drug can help with better retrieval, but there are many uncontrollable factors that affect the process.

Question: Is my heifer/ cow ins't getting pregnant, will flushing her fix it?
Answer: No, not typically

If you are experiencing reproductive problems, flushing probably won't fix them. Heifers or cows that do best are ones that are healthy and reproductively fit. Reproduction in a cow is among the first things to shut down when there are other problems with her.

Question: Does Flushing a cow cause her to run out of eggs sooner?
Answer: No, it doesn't

In fact, flushing a cow does not increase the number of eggs a cow will naturally release on each cycle. A finite number of eggs are available for each cycle of the cow. During the natural process of a cow coming into heat, the majority of the eggs are reabsorbed by the cow and usually one of these eggs survives the cycle and is ovulated. In the case of twins, two eggs survive the cycle. Embryo transfer allows all of the eggs that are released during the cycle to be harvested instead of just one. There will be a new number of possible eggs for the cow's next cycle. Embryo transfer simply utilizes the eggs that would have been discarded naturally.

Question: How often can I flush a cow?
Answer: Usually about once a month.

The answer to this question depends on the management strategy of the owner. Some cows are designated donors and are flushed monthly for several years while others are only flushed once or twice, bred back and returned to their herd. Cyclically, however, a cow can be flushed once a month.
