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.
The EXCAL Fast-flow tube-delivery teat was the fore-runner of all modern calfeteria teats for group feeding of large numbers of calves. The internal shape creates a pump-like effect as the calf bites it. The first biting action closes the base end of the teat, and further mouth closure forces milk out through the tip. Almost the same effects as when the calf is suckling naturally. The Fast-flow calf teat takes standard 11mm o.d. plastic tubing, and should be mounted at the most ideal suckling height for the calves being reared, with the delivery tubing descending into the milk container. EXCAL non-return valves should be used at the bottom of the milk tubes to prevent back-flow. The EXCAL Fast-flow teat is fitted into a 22mm diameter drilled hole, in any plastic or metal container or remote feeding panel.
Those of you who are old enough may remember feeding calves with an inflation on a beer bottle. Nowadays a beer bottle only feeds a piglet, so we found these nice new soft teats, for calves or lambs and kids, made to fit onto your standard soda bottle. Squeeze the bottle for speedy drinkers. Cut an X in teat end with razor or knife, or melt hole with hot nail (no hole supplied!)
The EXCAL teat intake elbow is supplied plain (white), or with stop valve (orange). The stop-valve model enhances suckling for newborn or weak calves (but it can be susceptible to blockage when used with some types of powder-mix milk. In these cases it is best to use the plain elbow). The intake elbow fits directly into the back of the teat and ensures suction from the very bottom of the bucket or feeder.
The Milkflow teat intake elbow is used to enable a 'gravity' teat to empty all the milk from the bottom of a feeding container. The elbow fits neatly and firmly into the back of the Big Softy teat. The internal dimension will take the tube-end of an EXCAL Stop Valve to further enhance its versatility. Dimensions are 10.25mm o.d., 7.35mm i.d., length 45mm o.a., enabling suction to a depth of 35mm from the centre of the teat. Sold in 10-packs only.
