Animals occasionally require shots – maybe a routine vaccination, pain medicine, or antibiotics. Avoid shots if other methods are available (for example, using a pour-on dewormer vs. an injectable dewormer). The type of shot to give depends on what is being given.
Package instructions should always include the proper method(s) of administration and that method should be used:
Types of shots:
IM: Intramuscular injections are injections put into the muscle of the animal.
IV: Intravenous injections are into a vein, such as the jugular or milk vein. Acts almost immediately.
SubQ: Subcutaneous injections are under the skin. For slow release or irritating medicines.
Slow release behind ear: For long term medicine, performed by vets.
NEEDLES: Use only STERILE needles! Throw away after using once.
Gauge: The smaller the number, the larger around the needle.
- SubQ: Use 16 gauge for cow; 18 gauge for calf under 300 pounds or when giving thin liquids;
- IM: Use 16 gauge for cow; 18 gauge for calf under 300 pounds or when giving thin liquids; 20 gauge can be used for calves when injecting thin liquids.
- IV: Use 14 gauge for cattle over 700 pounds (some use 16 gauge, smaller and slower); 16 gauge for 300-700 pound animals; 16 or 18 gauge for calves under 300 pounds;
- IV Oxytocin into milk vein: Use 28 gauge 1/2 cc syringes
Length: In inches
- IM: Antibiotics: 1-1.5 inch for calf – 2 inch for cow
- Vaccines: 1 inch for calf – 1.5 inch for cow
- IV: 2 inch
- SubQ: 1/2 – 1 inch
Max amount per location:
IM: 15 cc adult – 5-10 cc calf
IV: Large doses may be given. For example, one bottle of Calcium is 500mL (500cc) and more than one bottle (perhaps Calcium, then Dextrose or Saline) can be given at that one injection site for a cow. Ratio for calf would depend on treatment needs.
SubQ: Adults 20-30cc – Calf 7-10 cc
If you need to give more than the above doses, you can separate the dose by location. For example, 20 cc of IM injectables could be split between each side of the neck: 10 cc on the cow’s right side and 10 cc on the cow’s left side of her neck.
WHERE to GIVE SHOTS:
Picture a triangle in the center of the neck. Do not give too close to the jugular/windpipe area or too close to the top in the neck ligaments. If given often, alternate sides or move to the thigh. (left picture)
In the hip buttocks area, within the circle area of his hand, basically between hook bone and pin bone is another alternate site for IM injections. (see below)
Before giving the shot, firmly thump the area to desensitize the animal. Give the shot, wait a second after the medicine is in, remove the needle, cap the needle, then rub the area for a few seconds to disperse the medicine well:
