Teat Calf Excal Big Softy each 
The Big Softy makes all the other 'gravity' calf teats obsolete. With gravity feeders, (where the milk level is higher than the teat), two issues arise. First is preventing leakage through the teat, and second is whilst preventing leakage still enabling the calf to suckle freely. The Big Softy achieves both these ends. The tip design does not leak, even after substantial use, and yet the tip opens freely as soon as the calf begins suckling. The Big Softy will fit all feeders with standard 22mm (+/-1mm) teat holes. It is equally suitable for hand-held bottle feeding, or for top-teat tube delivery feeders. Big Softy is protected by New Zealand Design No 405207.
