Five Freedoms of Animal Welfare :
Lets talk about needle gauge table. The size of a hypodermic syringe or needle is indicated by a number that has units of “G” or Gauge. Gauge comes from the Birmingham Wire Gauge which is a measure of the size of the wire. Since the 19th century the British medical world used the gauge as a needle size.
Before getting to know the various sizes of syringes, let’s first know what a syringe is and how the history of a syringe is. In the medical world, the use of syringes is not a new thing.
Syringe is a tool used to help insert materials or compounds into the bodies. Basically, needle is used at the same time as a syringe.
The syringe was first invented by a French surgeon, Charles Gabriel Pravaz (1791-1853) and a doctor from Scotland, Alexander Wood (1817-1884). The syringe was first used to insert or inject morphine as a painkiller.
Please note, that the syringe is used to give drugs to the patient via the parenteral route. Administration of drugs by the parenteral route has advantages, drugs through a faster absorption route directly.
However, the technique of administration of drugs by the parenteral route must be carried out with caution. Medication or dose errors can be fatal to the patient.
Drug administration by parenteral route is divided into subcutaneous, intradermal, intravenous, and intramuscular. Each technique is used according to the needs of medical personnel and the conditions experienced by the patient at that time.
In the world of veterinary medicine, patients treated do not come from only one species. But many species with different physical characteristics. Starting from pets such as dogs and cats, to farm animals such as poultry and ruminants (cows, goats, sheep).
That is makes the use of syringes in veterinary medicine to have different specifications for one animal to another. Especially in terms of the use the size of syringe. The use of the size of syringe in cats is different from the use of the size of syringe in cattle.
Here is a table of hypodermic needle gauge table :

It can be seen from the syringe size table above that the larger the number “G” or Gauge, the smaller the diameter of the needle. So it can be concluded that the number “G” is inversely proportional. Also read about types of uterus in animals.
Thank you for reading the article about needle gauge table. Hopefully this article can help. Look forward to the next article.
