vessels and their skin is usually dark colored. In large adult pigs with proper restraint, a central dorsal ear vein can be used for IV injection and/or catheterization. An 18‐ or 20‐gauge, 1‐ to 1½‐in. hypodermic needle or butterfly catheter can be used for large adult pigs. A 21‐ or 23‐gauge butterfly catheter will be suitable for smaller‐sized pigs with small ears. This author prefers a butterfly catheter because it has a shorter needle and tends to stay in the vessel better than hypodermic needles, especially when the animal struggles during injection. Shorter needles are easier to hold in place and decrease the chance of perivascular injection. IM injection of anesthetics or anesthetic combinations to pigs has been shown to produce short‐term anesthesia effectively. Always keep in mind that pigs have a thick subcutaneous layer of fat, and thus, to ensure the drug is deposited into the muscle, a longer needle (≥1½ in. for large, mature pigs; 1 in. for piglets) should be used [23].
