Snap-on teat for feeding bottles with insert. Our inserts eliminate wasted milk while nursing. The embedded silicon membrane will only let milk pass while the calf is suckling, functioning naturally like a real cows teat. The implementation of an insert has allowed us to introduce a
round milk opening at the tip of the nipple. This 2 mm hole delivers consistent milk flow while the calf is suckling, increases longevity of the nipple and eliminates tearing. Narrowing the neck of the nipple in combination with our soft-touch synthetic rubber closely mimics a cows teat promoting nursing for adequate feeding.
