Well known lamb and kid feeding teat, which can be used in a calfeteria’ type feeder. The teat can be fitted through a 14mm hole and will take 11mm o.d. calfeteria-type delivery tubing in the back. Or it can be stretched over a ‘pop’ bottle as a bottle feeder (but needs an air-inlet in this configuration). Cross-cut or round-hole tip. Hole teat is softer.
