Rodent Feeding Needle Selection Guide

Choosing the right gavage needle for safe oral dosing of rodents can be a challenge. While there are no definitive guides on the exact size to use for each size of animal, this list has been compiled based on published papers, references, employee experience and anecdotal reports. For easy access to this guide, you can download the pdf.

Remember that the tube must extend from the tip of the nose to the last rib to ensure it’s in the stomach and not the esophagus. Even with that rule, the right feeding needle is the one that works best for you, so we recommend that you try more than one size in order to get the best fit.
