I keep 'em at a storage facility as I don't have a shipper tank for when someone wants some shipped. They do the shipping as well as
storing them. Same with my semen - well, that is, my bull's semen! (lol)
I guess the question really is where will you or how will you use them - if you intend to put them in your cows at your place keeping them in your semen tank is a good idea. If you intend to ship them or take the cows to the ET facility then keeping them in their semen tank is a good idea....
I have one to sell: it's an MVE XC 20/20. I bought it new at Hawkeye West (Billings, I think they "turned into" Genex) when I lived out there. I don't need it any more. It hasn't been filled for several years. It holds about 650 straws - that's considered small. I think I paid about $650 for it. It's supposed to be a good one and is like new. I don't really know what it's worth. Anyone got any ideas?
