Flushing Solution?

Q. I worked at a breeding farm when I was in high school, and after we inseminated the mare we flushed the tube with some type of solution that either was skim milk or reminded me of skim milk. What was that solution and was it necessary?


A. The solution you are referring to is semen extender. It is used to increase the volume of fluid inseminated, and it contains nutrients, antibiotics, etc. It usually is mixed with the semen rather than used for flushing, and it is not necessary for flushing.
