quote:I never really understood the subzero limitation. We kept bull semen frozen in a liquid nitrogen tank out on the dairy farm 40 years ago. Literally just an aluminum tank that sat under the eave of the barn. No power or anything. The insemination company would come by and refill the tank with liquid nitrogen every few weeks while delivering their product, but it was a pretty low-key operation for keeping that stuff frozen.
Once unfrozen they are reportedly good for up to a month.
