Third, once it was inserted, you could hold a moistened finger close to the back end of the tube. Or, you could blow into the tube. The instructions said that it IF the tube was in the stomach, you would see the lamb's abdomen inflate. IF it was in the lung, your breath would harmlessly blow back out through the lamb's mouth. I held the lamb, belly flat on the kitchen table, while Pam inserted the tube.
Memories are a little fuzzy on the specifics of the whole process.
Pam tentatively blew down the tube, but nothing happened. We decided to go for it. Pam hooked a large syringe onto the tube and poured in about half an ounce of colostrom. We watched as the the level of the colostrom in the syringe slowly dropped. Pam poured a total of a good two ounces down the tube.
