Abstract: An improved animal drinking valve is disclosed. The valve may be configured to penetrate a penetrable container containing a liquid for consumption by an animal. The valve also may include an internal actuator assembly including a spring member that biases an actuator member into liquid-tight interfacing with a sealing member situated within a bore of the valve. In this arrangement, the actuator assembly may provide the valve with two-way actuation; that is, the valve may be openable to allow liquid to flow therethrough when sufficient force is applied in directions perpendicular and/or parallel to a distal end of the actuator member. Also, the valve may be of dual-material construction, having a plastic body and a metal actuator member, improving resistance to chewing by animals and other physical degradation. Furthermore, the valve optionally may include one or more exterior fin-like projections that facilitate installation of the valve in a host platform.

Abstract: A high throughput process for delivering a semi-firm gel for supplying vaccines, nutritive substances and other similar material to animals, such as poultry chicks. The material is delivered in a non-absorbent semi-firm gel that is easily consumable which results in higher material uptake. The semi-firm gel is formed by interactions occurring between a solution containing an alginic acid crosslinking agent with a gel containing alginic acid.
