It is almost time to start breeding for the 2021 calf crop. Last week I talked about proper semen handling so this week I thought it was worth providing some information on care and handling of the liquid nitrogen tanks. The nitrogen tanks on our farms are likely storing semen and embryos that are very expensive to replace or maybe can’t be replaced. We need to take care of these tanks to make sure we don’t lose the contents.
Many people may be heading to the Ohio Beef Expo to pick up straws of semen and there are some things you should keep in mind.
Ideally, you would have a dry shipper tank to pick up your straws. This is the small tanks they use to send semen to your farm. These are called “dry shippers” because they should not have liquid in them. They contain an absorbent material that soaks up the liquid nitrogen and can maintain a temperature close to the temperature of liquid nitrogen for 1 to 3 weeks. The problem is that these tanks will cost as much or more than your standard storage tank and you need to recharge them with liquid nitrogen before using them.
