The Springer Magrath Fluidfeeder provides a practical, easy-to-use tool for providing fluids and nourishment to calves that are unable to nurse from a cow. The nipple is designed to allow liquid to leave the bottle while keeping air out. The easy-to-handle 2-quart tube makes using the Fluidfeeder a simple, one-person operation. When used properly, the rate of flow is slow enough to cause the calf to form saliva freely, which is necessary for proper digestion. Durable plastic probe resists burs that can cut the throat and cause infection; heavy-duty tube resists punctures and tears and remains flexible down to 0 degree F. (-18 degrees C.). Bottle collapses without venting, and check valve keeps air out as liquid leaves the bottle. Bottle, tube, probe, and nipple are easy to clean.
