Check the listing for details. Calf Oral Fluid Feeder 2 quart Esophageal Plastic Probe Magrath. Condition: New. Listed at 28.71 USD. The Springer Magrath Fluidfeeder provides a practical, easy-to-use tool for providing fluids and nourishment to calves that ca not or will not nurse. The 24in flexible esophageal probe is the correct size for calves, and if used properly, the probes size and shape do not allow it to be inserted into the trachea, reducing the danger of getting fluid into lungs and drowning the calf. The easy-to-handle 2-quart tube makes using the Fluidfeeder a simple, one-person operation. Crimp valve allows easy control of fluid; 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, and probe are easy to clean. 2 Quart size. Thanks for looking and have a fine day.
