A mouthpiece of elastic material for a drinkwater valve for cattle has an elastic wall which encloses a water discharge chamber and is provided with one or more water ducts. A valve member extends from the drinkwater valve into the water discharge chamber and is actuated in response to pressure exerted by the cattle on the mouthpiece to admit water into the discharge chamber. Continued pressure on the mouthpiece by the cattle forces the water from the discharge chamber through the water ducts into the mouth of the cattle.
