Below is a brief overview of its application in chickens:

1. What is LA-200?

LA-200 is a long-acting, broad-spectrum antibiotic that belongs to the tetracycline class.

It is effective against gram-positive and gram-negative bacteria, rickettsiae, chlamydiae, and certain protozoa.

While it isn’t specifically labeled for poultry, some chicken keepers have found it beneficial for treating respiratory infections, certain bacterial infections, and chronic diseases like chronic respiratory disease (CRD).

3. Dosage and Administration:

Always consult a veterinarian before administering any medication to your poultry.

The dosage for chickens is not officially defined, so a veterinarian’s advice is crucial to avoid complications or resistance.

NOTE: Overuse or incorrect use of antibiotics in chickens can lead to antibiotic resistance, which makes infections harder to treat and can result in the spread of antibiotic-resistant bacteria.

4. Withdrawal Period:

After treating chickens with antibiotics, there’s a withdrawal period during which their eggs and meat should not be consumed.

This period allows time for the medication residues to leave the chicken’s system.

Since LA-200 is not officially labeled for poultry, there’s no defined withdrawal period for chickens. Consult with a veterinarian to establish an appropriate withdrawal time.

LA-200 is generally considered safe when used as directed. However, any medication can cause side effects. Possible side effects in chickens might include allergic reactions or digestive disturbances.

  • Monitor chickens for adverse reactions.
  • Avoid concurrent use with other medications unless advised by a vet.
  • Store the medication in a cool, dry place out of direct sunlight.

6. Alternative Medications:

There are many antibiotics available for treating poultry diseases. If you’re uncertain about using LA-200, discuss with your vet about alternatives such as Tylan, Duramycin, or others specifically formulated for poultry.


While LA-200 has its place in livestock medicine, it’s essential to use it judiciously in chickens. Always work with a qualified veterinarian when considering antibiotics for your flock to ensure the health and safety of both your birds and those consuming their products.
