Subcutaneous injection

Injections

There are several ways to inject animals with drugs and vaccines.

Intramuscular injections

Inject into the muscle of the hip, the upper back leg, the middle of the neck, the shoulder or chest muscles. Point the needle straight into the muscle. Before injecting the drug, pull back the plunger a little to make sure that the needle did not enter a blood vessel. If blood enters the barrel of the syringe pull the syringe out and try another place. If no blood enters the barrel inject the drug into the animal.

Intravenous injections

This injection is made into the big vein (jugular) in the neck. This vein collects blood from the head and carries it to the heart.

You will need someone to help you to control the animal and to find the vein. In order to make the vein show, block it at the base of the neck. Use your hand to do this in small animals and for large animals use a rope around the bottom of the neck. Blocking the vein will make the blood build up inside it and it will stand out like a cord or rope under the skin. Put the needle into the vein. Check that the needle is in the vein by pulling the plunger of the syringe, back a little when blood should show in the barrel. Remove your hand, or the rope, from the bottom of the neck and slowly inject the drug.

Subcutaneous injection

This means injecting under the skin. It is done by picking up a loose fold of skin from the neck or shoulder. Take care not to inject into your fingers or that you push the needle in so much that it comes out on the other side of the skin fold.

Intramammary injection

It is used to empty antibiotics in an intramammary tube into the udder or to put drugs into the udder using a teat catheter.

Remember that before you make any injection you should pick an area of skin free from faeces or mud, use a clean sterilized syringe and properly fitted needle, make sure your hands are clean

1. What are the ways to inject animals with drugs and vaccines?

2. Into which parts of the body should the intramuscular injections be done?

3. Into which veins should the intravenous injections be done?

4. How should we do the subcutaneous injections?

5. How should we do the intramammary injections?
