For adults and large pigs when injecting im a 4 cm needle is required. Weaners when injected im will require a 2.5 cm needle and piglets will require a 1 cm needle. For sub-cutaneous injection, e.g. when giving local anaesthetic above the mammary gland for a Caesarean section, a 5 cm needle will be useful so that it can be advanced slowly injecting local anaesthetic continuously up to its full length. This avoids repeated skin injections. For blood testing adults a 5 cm needle will be required for the jugular but a 2 cm needle will be more appropriate for an ear vein.
