Need help reading a bottle of Ronidazole

I see where the OP was treating for the same thing 2 years ago. Canker is contagious, and the whole flock should be considered as carriers since they are drinking from the same waterers. I would clean and disinfect all waterers and feeders, and you might want to treat your flock with some acidified copper sulfate 1/4 tsp per gallon of water for 3 days a month as a preventative to the other birds not showing any symptoms. Here is where to get it:

Hey thank you so much! I've heard about this treatment but i didnt know where to get the powder. I'll order it as soon as I can! :thumbsup

This is probably a late reply, but when it comes to medications, how long will it take for it to take its full effect? I've noticed there hasn't been much of a change in their flare ups. The last time i treated it was gone within a week. However i was also running thyme on it, a study showed that putting thyme on the canker "destroyed the parasites". So I'm like could've it had been the thyme and the metronidazole working together that knocked it out?


Here's the link to the study i found

You probably know a lot more about canker than I do. I haven’t ever seen it in my flock, only have read about it, and helped people with medication and dosages. It can be mistaken for the wet form of fowl pox sometimes. Some have reported having to remove some of the canker growths, but they do bleed a lot. I hope that you can control it in your flock.
 
Hi, One of my roosters was very sick and I took him to the vet. He had an overload of capillaria roundworms, and sores in his mouth, which the vet said were likely canker and prescribed doxycycline, and something for the roundworms.
I came home and treated my entire flock with ronidazole and fenbendazole. Later I read that there is a lifetime egg withdrawal from using ronidazole.
I told my vet and he said, “I’m sorry.” Then he said I could maybe withhold eggs for 14 days and eat them, as long as I don’t sell them.
What is y’all’s experience with egg withdrawal from ronidazole? Lifetime withdrawal seems excessive.
PS, a month later, my rooster is finally improving.
Thank you so much!
 
Ronidazole is known to have carcinogenic properties, it, and the whole class of drugs of it's type do not have a recommended withdrawl period and are banned in poultry for that reason, in the US (and the UK I believe). There are studies on other animals that found persistant traces of residue in some species. When using medications on laying hens that may cause residues in eggs the withdrawl period is usually about 2 weeks (many medications have not been studied in chickens at all) to allow for all eggs that are in the process of forming to be laid. Meat withdrawl periods (for birds to be eaten) are often different, and can cause a recommended withdrawl to be longer than the two weeks, or less. I've never used it, have not had to treat for canker, and have other medications that I've used for other things, so no personal experience. Many have used metronidazole, which is in the same class. I've attached a few links that may be helpful. Many vets prescribe medications for birds considered pets, that they might not prescribe for a bird intended for food production. Probably why your vet prescribed the doxycyline rather than ronidazole.
Canker is stubborn and birds are considered carriers, you often have to do repeat, monthly treatments to keep it controlled.

Thank you so much for your response. I tried to sift through the information you sent and can't really find out why there is a permanent egg withdrawal after using Ronidazole.

From what you wrote, I think you meant that it might be safe to eat the eggs after 2 weeks? My vet said something similar when I asked him. The bird that my vet saw was a rooster, so no problem there on egg withdrawal.

While searching I found an article about toltrazuril that said a study was done and there were still residues after 40 days of being treated.

I contacted the manufacturer of the Ronidazole and was told I should never eat the eggs again.

That seems extreme, and I want to believe that it will be OK to eat the eggs after 2 weeks, but am afraid to.

Thanks again.
 
Often a permanent withdrawl is recommended because there are not any studies done to actually tell if there are any residues. So out of an abundance of caution, they say never eat the eggs. This is unfortunately true a lot for chickens, no good studies. Most things are based on industrial farming, and those birds generally only live a short time, and are often isolated indoors and not exposed to all the things that back yard flocks are. Studies cost money, and if they can't justify the cost, they don't get done. So we have to research as best we can, and try to make the best decision for ourselves. I know that there are studies that show long term residual residues in meat for some species, but eggs are not studied.
