Immunizations:
Injections &
Techniques
1
Objectives
• To learn why injections are essential for
healthy animals.
• To learn the different sizes of syringes
and needles.
• To explore injection sites on the animal.
• To become familiar with medicinal
applications.
2
Types of Syringes
• Disposable - mostly plastic, usually
thrown away after use
• Reusable - made of glass, plastic and
metal; must be sanitized between each
use
• Automatic - delivers larger doses
repeatedly; ideal for
vaccinating sows, steers
and cows
3
Syringes
• Consist of a barrel
and plunger
• Types of needle attachments
– plain tip - simply pushed on the tip of the
syringe
– lock tip - twists and locks onto the tip of the
syringe
– may be made of plastic or metal
4
Syringe & Needle Sizes
• Syringes and needles are sized by
gauge (diameter) and length
• Common syringe sizes: 1, 3, 6, 10,
12, 16, 18, 20, 30 and 50
• Common needle gauges: 16, 18
and 20
– the smaller the gauge number, the
larger the needle
• Common needle lengths (inches):
¼, ½, ¾, 1, 1¼, 1½ and 2

Types of Injections
• Cutaneous - material is applied to the skin
• Epidural - injected directly into the area
around the spinal cord
• Intracardial - injected directly into the heart
• Intradermal - injected into the skin
• Intramuscular - injected into the large
muscles, commonly the neck and thigh
7
Types of Injections
• Intraocular - injected under the eyelid or into
the cornea
• Intrapulmonary - injected directly into the
lungs
• Intrathoracic - injected into the thoracic area
• Intravenous - injected into the vein
• Subcutaneous - injected under the skin
(subcue)
8
Needles & Injections
• Intramuscular injections - 1” needle use
is common for young animals and 1.5”
needle for adults
• Subcutaneous injections - ½” to 1”
needle is favorable
* thicker medicines may require smaller
gauged needles in order to “push” the
medicine through the syringe and needle
9
Types of Medicines
• Wormers
– used to kill parasites
– usually given orally or subcutaneously
• Vitamins and minerals
– given when an animal is deficient
– usually given orally, intravenously or
intramuscularly
10
Types of Medicines
• Antibiotics
– a bacteria-killing substance produced by a
bacterium or mold given to cure bacterial diseases
– usually given orally, intravenously or
intramuscularly
• Vaccines
– substance containing live, modified or dead
organisms; injected to build immunity from a
disease caused by certain organisms
– usually given intramuscularly or subcutaneously
11
Types of Medicines
• Serum
– fluid portion of blood from animals having
immunity to the disease
– produces a passive immunity until the animal
produces its own
– usually given intramuscularly or with a vaccine
12
Precautions
• Precautions for biological products,
such as antibiotics and vaccines,
include the following:
1. protect from heat and light, keep in a
refrigerator at 35°F to 45°F. DO NOT
FREEZE!
2. only put sterilized needle into container
of medicine
3. only use recommended dosage
13
Regulations for Animal Drug Use
• Federal regulations require manufacturers to
label all containers to supply buyers with
information on proper handling, storage and
drug usage
• Some drugs can only be prescribed or sold
by veterinarians
• Most drugs have withdrawal periods and
buyers must be careful when giving drugs to
animals to be slaughtered
• Many drugs are only made for a specific
species
14
Oral Medicine Application
• Methods of giving medicines orally
include:
– drinking water
– feeding
– drenching with a drench gun
– bolus with a balling gun
– tubing with a stomach tube
