I recently received my semen order for fall breeding. I took the vapor shipper to the UPS store for return. They are always concerned about what is being shipped in regards to hazardous materials, biologicals, pathogens, blood, etc. The young girl asked "what is in there". I had to think about how to answer. There are some words that you don't use or they may refuse to take the shipment or require all kinds of labeling and paperwork. I knew to not mention liquid nitrogen. I told her it was a refrigerated container for shipping bull semen, but that it was empty and being returned to the shipper. She accepted the answer and gave me the printed receipt. Might have been a little uncomfortable for both of us.
I think it takes a very special person to ask for bull semen for Christmas.
