I gave LA-200 injections subcutaneously along with Tetracyclines in the drinking water when I treated my birds for Coryza. One of the three got swollen lumps at the injection sites, but they healed after a week or so. I think intramuscular injections carry risk of greater damage.
I've treated her since with LA-200, but tried to minimize since she has reactions. I gave half her dose by injection & half orally once (plus some more orally before next injection was due, since I don't think it stays in system as long orally); & recently injected half the dose near one of her legs & half near the other leg.
I think LA-200 can be pretty painful. Now that I've learned that Bio-Mycin (another brand of Oxytetracycline injectible) has an anti-sting ingredient added, I will buy it instead in the future.
Dose details:
Average chicken weighs roughly 5 lbs, which is 2.27 kg. (More specific breed weights are listed on the "Poultry Body Weights" page on my site).
In the links above, maximum Oxytetracycline dose listed in for chickens is 200 mg actual Oxytetracycline per each kg of chicken's bodyweight. Duramycin 72-200 (and LA-200) have 200 mg Oxytetracycline in each mL of liquid.
2.27 kg bodyweight X 1 mL (=200 mg dose for each kg) = 2.27 mL total dose (which is the same as 2.27 cc)
I think 2.27 cc is an awful lot to inject into a chicken, so I've always used a lower dose (The most I've injected has been 1.15 cc) & then also combined with either a Tetracycline powder in the drinking water, or a different med that synergistically boosts the effectiveness of Tetracyclines. Meds that work synergistically with Tetracyclines include Denagard and Neomycin, but those should be used just if birds' illness indicates they would be good to add in. I like that they make it so less Tetracycline is needed for more effectiveness.
I would also guess that the "72" in the name of Duramycin 72-200 would refer to its lasting 72 hours in the body system, so it only needs to be administered once every 3 days.
Vets make errors like all the rest of us, of course. I've had several who treated my animals make significant mistakes or omissions. I just try to confirm info they give me with what I can find on the internet & thoroughly discuss their ideas with them.
