A continuation of my previous stomach tubing videos, this method works well with gravity fed tubers, and allows you to visually assess how full the lamb is based on their belly size, not how much milk you are feeding them.
I should mention here as I regretfully forgot to comment in the video that when inserting the tube, you want it to go down the side of the mouth, keep gentle but firm pressure on it. Do not put it straight into the mouth as you risk going into the lungs instead of the stomach. If you meet a significant resistance, pull it out and try again.
