$350-$400 !!! 8O Sheesh! I've been showing folks how to do it for years for nothing!!! I learned as part of my animal science degree and worked as a lab tech for a university. One of my jobs was to teach grad students how to AI..... That was many years ago, but I still teach folks that only have a cow or two.
I am teaching a goat AI class in a couple of weeks for a 4-H club in Norman, Ok. In all honesty, if you can read, you can learn to AI. There are several animal science reproduction textbooks that can tell you how. It is a bit "up close and personal" for people new to livestock tho.....

I'd have to go and look but I think that my tank hold 250 straws. I have it pretty full and I am considering getting another one before the year is out. One for goats and one for cows..... it is the pits to be trying to find goat semen and pulling up bull stuff.....
Most larger cattle operations have a tank and nearly all dairy farms. Some of them are pretty generous about letting you store semen in their tank in exchange for paying for some of the liquid nitrogen on occasion. I allow people to keep one cane/year in my tank in exchange for them paying for one nitrogen fill up which runs $20 every six weeks. One cane holds 10 straws. Usually, I am the one who will AI their animal anyway so I just haul the tank with me when I go. I end up paying for 2-3 fill ups out of my own pocket.
This is my second tank in 11 years. They really last if you don't set them on concrete. I bought this tank because I just needed more straw space and here I am in the same situation again. I traded the old one in on this one.

You mean like...... they always come into heat so that they have to be bred at midnight and it is below freezing, raining/sleet, the north wind is blowing at 35mph and the hussy has broken down the gate and gone to the back pasture???? You can't find a working flashlight, the truck won't crank, the horse crowhops for the first 30 minutes after you FINALLY catch him and will not do the gate opening thing he was specifically trained to do?
Meanwhile, Bossy is bellowing sweet nothings across a weak fence to the rank sale barn bull that your neighbor bought---- and you are begining to think that he reeeaaaally isn't THAT bad of a bull......

Most dairy barns (if they are grade A) have a concrete floor. These tanks are not terribly heavy but they are not featherweight either. I find that folks end up sliding them across the concrete floor and just wearing the bottoms very thin. All it takes is a small hole to break the insulating seal. These are really just big thermos jugs. It then " leaks"..... not really the nitrogen but just doesn't insulate well so that the nitrogen evaporates off quicky.
When the nitrogen is gone, theoretically in 90 seconds your semen is thawed out and very quickly dies.
I learned a sad lesson about tank upkeep.
Last fall, our dairy goat club sponsored a buck collection. One of the goat owners could not stay until it was all processed. So I told her that I would take her tank home and she could pick it up from there. She didn't do that. I checked on it and had it filled when the guy came around a few days after I brought it home. I then promptly forgot about it. The nitrogen guy comes around every 6 weeks. A month passes, my tank is still in the cardboard box I bought it in 5 years ago and well protected, but hers is an older used tank that looks like it has been kicked around a bit. One day, I pass by and see it and remember that she was supposed to have picked it up over 6 weeks ago...... I check it and------ totally dry. About $600 worth of semen dead. I am just sick, she is mad as all get out because I didn't check it regularly and I am looking like the bad guy. I did not pay to replace all that semen..... I am still not her favorite person and I only feel slightly guilty for offering to help out in the first place. :rolleyes: I did give her some semen from one of my bucks that she liked. Then I found out several weeks later that she had somebody else's semen in there, too.
So now, I handle only my tanks and I check the nitro level every two weeks.
