One of the most common mistakes made on farm is using the same esophageal feeder to give fluids to a sick calf and then to deliver colostrum to a newborn calf.

It’s a very easy mistake to make, and when dealing with an infectious disease such as salmonella, it can be a very costly mistake, says John House, associate clinical professor of veterinary medicine at the Veterinary Teaching Hospital at the University of California-Davis. Esophageal feeders are cheap. Buy several and color code them so that their use is restricted to a single function.
