Detailing proper semen handling procedures from the University of Missouri Extension. Taken at Foremost Dairy Center
Summary:
Inside the tank: A straw, labelled with the ID of the bull. Straws are contained on a goblet, which is attached to a cane, which go into canisters, which are lowered into liquid nitrogen.
Pull semen from nitrogen tank, and place it into the thaw bath. Wait 45 seconds, then remove and dry the unit. Load the AI gun, clip the end of the straw, and attach the sheath to the gun. Keep the gun warm on the way to breed the cow.
