The better half had some friends at school who worked as dairy cattle inseminators one Summer. You really develop a dark sense of humor in that line of work. "Hi honey, just called to ask where you are?" "Oh, I'm shoulder deep in a cow." (I've had this discussion too). Also, I've heard when getting specimens for use in dog insemination, the collection is a rock paper scissors sort of deal among the staff at the vet office.I am doing it myself.
I saw it done once, did some reseearch and watched a youtube.
I am almost an expert.
Pig semen can be shipped fresh or frozen
I have contemplated getting a liquid nitrogen set up and doing semen distribution fpr goats pigs and cattle later on
