[QUOTE="inyati13, post: 981371, member: 17767"] Hi Bigfoot, good to see a neighbor's comment! No, but I would like to. When I first got started about 3 years ago, I had four cows. I decided to have them artificially bred. Well, Joe (guy in this area who does AI, not his real name) synchronized them and then bred them all at the same time. Only one took. After that, I would watch and when one was ready, I would call him. But one thing or the other always went wrong; mostly he was late. Sometimes a day late and no one has to be remotely familiar with the reproductive system of a mammal to know that isn’t going to work. It isn’t like they are amphibians that can store sperm for years in their seminal vesicles and use it when they need it. :lol2: I can't remember but there are some vertebrates that only mate once in their life and they store the sperm to be used for the rest of their life. I have thought about teaching myself and getting the equipment and giving it a try. (I am talking about doing AI not storing my sperm). It looks easy to me. I worked with mice in reproductive physiology. Although we let the male do the fertilization, we removed the zygotes. I have never seen a cow flushed, but I have flushed zygotes from the uterus of a mouse in which case the mouse is killed by cervical separation (broken neck) and the uterus is removed placed in a Petri dish and the zygotes are flushed out with a micropipette. All done under a dissecting microscope. I watched Joe, looks like the hardest part of what he does is keeping the feces off him. :lol: Actually, jokes aside, I am sure their are critical protocols like procedures to ensure the semen is viable and stays viable.
