When we vaccinate baby pigs, we run 4 syringes and vaccinate 1500-2000 baby pigs at a time. I ordered these syringes as replacements, however most of our employee's try not to use them as they are very stiff, and the repetition involved in vaccinating that many animals is very hard on your wrist/hand. We prefer to use these only when giving a few shots vs. many shots. They are a sturdy syringe, just not good for 100's of shots in a short time.
