Semen tank.... a tank with a vacuum layer, that hold liquid nitrogen, for the storage of semen that is used to breed animals with... The bull studs for cattle have different bulls that are collected and that semen is used for breeding the cattle artificially. It is the way to breed cattle to most any bull you can afford... to improve your animals.... without the hassle of having and maintaining a bull on your property and the multitude of problems that can create.
The semen is collected at these special farms that house only bulls.... they live in some pretty "posh" digs, and just have to contribute semen for use all over the country and the world... The semen is checked for quality, some is sorted for bulls or heifers (the semen carrying the x or y chromosome) then a carrier liquid is added ... and flash frozen in very small 1/4 or 1/2 cc straws... it has to be kept in the liquid nitrogen until someone wants to use it, then it is thawed and used to breed a cow..
There is also goat semen that is frozen, I believe @rachels.haven has bred some AI.... I assume that some sheep have been bred AI but I don't know of anyone that does... They also use breed pigs AI... but if I am not mistaken it is NOT frozen, just chilled very low temps and overnighted and has to be used in xx amount of hours...
The liquid nitrogen will evaporate slowly... and the tanks have to be refilled/recharged every 2-4 months... all according to what type tank you have... Most are 90 or 120 day tanks... The guy comes from Select Sires to do my tank every 3 months.... If the semen tank "goes dry" and the semen thaws, it cannot be refrozen and you are out hundreds or thousands of dollars... One straw is anywhere from a cheap $10 to as much as several hundred.... Most of what is in my tank is $25-75 straws....
