CRD - Duramycin dosage for chickens?

[welovechickens]

I need dosage info for my 3 chickens - they are 12 weeks old today, and this morning I found my Japanese Bantam with a foamy eye and swollen nostrils. Her voice is croaky, and she sneezed a few times. Around her eyes is swollen and red too....she looks just like me when I have a cold! lol...poor thing!

I got Duramycin-10, but I need to figure the dosage for 400mg in 1/2gal water. The directions on the back of the package are for using the entire 6.4ozs of powder.....I am not going to mix 25gal of medicine water for 3 chickens!

I was hoping maybe there was a chart somewhere, or someone else figured this out first. I am horrible at math! LOL

The last post from ToniLee is exactly correct and some of the other posts had incorrect information. I'm a pharmacist and I just calculated it out, (after I measured the exact amount of powder in one package of Duramycin-10, 6.5oz, just to make sure.)

One package has 13 tbsp in it and you need roughly (rounding up for simplicity reasons) 1 tablespoon of Duramycin-10 per gallon of water. That breaks down to 3/4 teaspoon per quart of drinking water. The solution is stable for only 24 hours and new solution must be mixed up every day. Treatment is NOT for 3 days (as posted earlier in this thread) but rather for a minimum of 7 days or you will get resistance.

And trust me, you do NOT want to develop resistance to this antibiotic or you will have to move to Tylan, which is much more expensive and harder to obtain. It's all to easy to get resistance to CRD in large flocks (50+ birds), as they keep spreading it from one to another. So just as soon as you get done isolating and treating some of your chickens and think you have it erradicated, you lose another chicken to it. Pretty soon, the drug doesn't seem to be working and voila, you have a resistant strain of CRD to that antibiotic. (I just had that happen, and with Tylan of all things.) Don't let it happen to you or your losses could be very high.

So in summary...

1 package of Duramycin-10 (tetracycline HCl) = 6.5 oz

1 package = 13 tablespoons

800mg/gal dosage: 1 tbsp per gallon

800mg/gal dosage: 3/4 tsp per gallon

Hope that helps!

I missed this one.

Here's what I would do:

1. Run through a full course of Duramycin. Observe for health and run a course of Denagard, if well enough. Supplement with probiotics- I would use what TSC has and baby parrot formula.

2. Move chicks to a different coop outside, keep separate. Very separate. Wash hands well between flocks and never wear the same shoes around them.

3. If all of the adult flock seem well and asymptomatic- no sneezes, no wheezes, no symptoms at all for 2 weeks- introduce one sacrificial bird. Use a cage, as you'll likely get the bird beat up if you don't. You'll need to observe this bird for at least 2 weeks, but I'm not positive on the incubation period for this. If the sacrificial bird becomes symptomatic, you know you have a carrier. That's the only way to know.

Here's a bit more info: http://www.merckvetmanual.com/mvm/index.jsp?cfile=htm/bc/203402.htm

Here is the info altho you will in my opinion be best served (to ensure the proper dosage and concentration) by calling the number given at the bottom of the page and asking a service representative (you want the 800 mg concentration) ... they are usually very helpful and will ensure you get the correct info for the smaller amount you need.

excerpt (important):
"....Tetracycline Hydrochloride Soluble Powder
Duramycin 10 Caution
Prepare fresh solutions at least once a day; solutions are not stable for more than 24 hours. Use as sole source of tetracycline. Deliver the recommended dosage level in divided doses. Diagnosis should be reconsidered if improvement is not noticed within 3 days. The concentration of drug required in medicated water must be adequate to compensate for variations in the age and class of animals, feed consumption, and environmental temperature and humidity, each of which affects water consumption..."

I ended up figuring out the amount for 400mg in 1/2 gallon water. The package says chickens should have 400-800mg....so I started with 400. Is 800 the best for them? I can switch since today is only their first dose.

 

[dlhunicorn]

go with the 800 milligram

 

[welovechickens]

ok, thanks!

I have the same product, and only need a few gallons a day, so I was wondering the same thing. You said you figured it out, what did you come up with for 400 and 800 mg per gallon? I came up with 1 tsp per gal for 400 and of course 2 tsp for 800.

Hi, did you ever find the answer to the conversion? I'm in the same situation. I have three laying hens that I need to administer tetracycline to, and I can't find the proper conversion on the web. HELP!

Most of the time that type of meds do not work, as it is caused by a virus. Tylan 50 used as an injectable helps them get over it better, but it can be a carrier state if either CRD(MG/MS) or Coryza....
