Abstract
A two part mastitis cannula cap includes an outer cap and an inner cap. The inner cap is not as long as the cannula so that a free end of the cannula protrudes beyond an end face of the inner cap. This cannula protrusion is covered by the outer cap which is securable about the free end of the inner cap. Controlled depth partial insertion of the cannula into the teat canal of a dairy cow can be accomplished by removal of only the outer cap. Alternatively, full depth cannula insertion is accomplishable upon removal of the two parts of the cap. In one embodiment, a snap-off outer cap is used. In a second embodiment, a twist-off or breakaway outer cap is utilized.
