Lambs and kids learn to nurse quicker and easier over the old style black rubber teat. Screws onto glass pop and soda bottles. Made of soft, pliable latex. Special flutter valve prevents air intake by the animal nursing. The flutter valve teat is one of the best nipples for feeding weak or newborn lambs. Cut off the tip just enough to allow adequate milk flow. These are Original Pritchard nipples, not copies. 

Note: These have been changed by the manufacturer, they no longer have the rubber O-ring inside. They claim this new design is better
