Presentation Transcript

  1. Colostrum timing is critical • Short-lived ability to absorb large molecules • Not after 24 hr • Digestive enzymes still low for first 12 hours • Potential for pathogenic bacterial colonization in the intestine • Unabsorbed antibodies line the calf’s intestinal tract

  2. Maximum absorption • 35% of ingested immunoglobulins absorbed when colostrum fed immediately after birth Average absorption Feed Colostrum within 1 hour after birth

  3. Source: Journal of Dairy Science (1979) 62:1766-1773. Calf’s ability to absorb antibodies declines rapidly over the first 24 hours

  4. Weak or sick calves • Some newborn calves are too weak to suckle or nurse from a pail or bottle. The esophageal feeder is an excellent aid for feeding colostrum to these calves.

  5. Consists of an esophageal probe, tube, clamp, and collapsible fluid-container. Rigid or semi-flexible tube Tear-shaped end to fit the esophagus Esophageal feeder design

  6. Clean thoroughly. Warm colostrum to body temperature. Calves should stand while feeding to prevent fluids from backing up in to the lungs although weak calves may be fed while lying down. Proper use

  7. Measure from the tip of the nose to the point of the elbow. Mark with tape In general, in young calves, pass only about 20 inches into the mouth and esophagus. Step 1:Insert how much tube?

  8. If the tube is cold, place it in warm water to make it more pliable. Lubricate the end with mineral oil, colostrum, or some other lubricant. Step 2:Before insertion

  9. Most calves will suck the end of the tube when it is offered Apply pressure to the corner of the mouth or over the bridge of the nose on the palate . Step 3:Opening the mouth…

  10. Step 4:Passing the tube • Slowly pass the tube along the tongue to the back of the mouth. • When the tube is over the back of the tongue, the calf will start chewing and swallowing.

  11. When properly positioned, you'll feel the rigid rings of the trachea and the enlarged smooth esophagus on the left side. Spurts of air in the exposed end of the tube indicate improper positioning in the trachea. Step 4 continued:Finding the esophagus

  12. Step 5:Delivering colostrum • Now, unclip the tube to drain the liquid. • Hold or suspend the bag and tube above the calf and allow several minutes to drain.

  13. Slowly remove the tube when you're done Clean, sanitize, and drain the feeder. Step 6:Removal and storage
