Semen can be easily shipped through the use of a dry liquid nitrogen tank or dry shipper. Movement of frozen semen straws from one cane to another should be done under liquid nitrogen to ensure semen quality is not damaged due to changes in temperatures. These containers are filled with liquid nitrogen or charged. The liquid nitrogen is absorbed into the linear of the tank keeping it cold without having free liquid in the tank. These tanks are then transported typically via UPS or FedEx
