Tube Feeding Colostrum to a Newborn Calf: First Aid Steps

Quick answer

Use a clean esophageal feeder like the Springer Magrath 2 Quart Fluid Feeder to deliver colostrum or a colostrum replacer such as Colostrx CR when a newborn calf cannot or will not nurse. Follow the steps below to reduce the risk of fluid entering the lungs and to give the calf the best chance at absorbing immunity.

Step-by-step tube feeding for newborn calves

1. Warm and restrain the calf: Move the calf to a dry, warm area and confirm it is breathing normally. If it is chilled, warm it first—tube feeding a cold calf can cause complications. Use a halter or a helper to keep the calf standing or resting upright. A calf that is shivering or has a temperature below normal should be warmed before any feeding.
2. Measure and mark the tube: Measure from the calf’s mouth to the point of the shoulder (or the last rib) and mark the tube with tape at that length. This helps you know when the probe is deep enough without guessing. If the mark reaches the mouth before the tube is fully inserted, stop and reassess.
3. Lubricate and insert gently: Apply a water-based lubricant to the probe tip. With the calf’s head held in a natural position, pass the tube slowly along the side of the mouth and into the esophagus. Never force it. A calf that coughs, struggles, or breathes rapidly during insertion may have the tube in the wrong place—withdraw and try again.
4. Confirm placement: Before feeding, check for signs of correct placement: the tube should pass easily, you may see it move under the skin on the left side of the neck, and the calf should not cough. If in doubt, do not feed. When placement is uncertain, remove the tube and start over—never feed ‘just in case’.
5. Administer colostrum slowly: Attach the feeder bag or bottle and allow the colostrum to flow by gravity. Keep the bag at a moderate height so the calf receives a steady but not rapid flow. The entire feeding should take several minutes. If the calf shows discomfort or fluid comes back up, pause and recheck the tube.
6. Remove the tube and clean equipment: When the bag is empty, pinch or clamp the tube before withdrawing it smoothly. Wash the feeder with warm soapy water, rinse thoroughly, and hang to dry. Clean equipment prevents bacterial growth that can cause scours. Never store a wet feeder sealed—allow it to air-dry completely.

Product facts

• Springer Magrath 2 Quart Fluid Feeder: The 24-inch flexible esophageal probe is sized for calves and, when used properly, its shape helps prevent insertion into the trachea. This design reduces the risk of delivering fluid into the lungs, but correct placement must still be confirmed before feeding.

  

• Colostrx CR Bovine IgG Colostrum Replacer 16 oz: Colostrx CR Bovine IgG Colostrum Replacer delivers 100g of whole bovine IgG per dose and aids in treating Failure of Passive Transfer. A concentrated IgG source gives a newborn calf a measurable amount of antibodies when maternal colostrum is unavailable or insufficient.
