These are often colour coded. For a viscous liquid to be given im to an adult sow with some speed, a 14 gauge (orange) is useful. Often a 16 gauge (grey) is sufficient. For quiet sows or gilts an 18 gauge (pink) is adequate, particularly if the liquid is free flowing. For weaner pigs a 19 gauge (yellow) should be used. For piglets if the fluid is viscous a 21 gauge (green) is required, but if the liquid is free flowing a 23 gauge (blue) will be fine. For blood testing sows a 19 gauge (pink) should be used into the jugular but a 21 gauge (green) should be used in the ear vein. For blood testing gilts or weaners into the vena cava a 19 gauge (yellow) should be used. A 23 gauge (blue) will be adequate into the ear vein.
