Peach Teats heavy duty 2 quart nursing bottle has a peach teat nipple that is screwed in the cap. The Peach Teat vented cap pulls air
through vent as the calf sucks, creating increased air flow. Peach Teats function
like a cow’s udder naturally would,
allowing the calf to suckle more intensely than conventional technology. The internal collapsing flap-valve holds the milk
in the teat, making it much more responsive to the calf’s needs. It is designed
to function like a real cow’s teat, moving all the time while the calf is
suckling, never closing in its relaxed state.
