The question is often asked. “I have 10 lambs to vaccinate and the 50 dose bottle I am using has a label that says destroy contents if not immediately used.” I have a way that this isn’t a problem. Simply add 5cc of aqueous pen to the bottle, store in the refrigerator and use till gone. Obviously I am referring to bacterins such as CDT, CD, Vibrio and others, not live products.
