Sulfadimethonxine (40% injectable) - Need water/oral dosage for a sick hen

[chickenflock01]

Hey guys, I was able to get the sulfadimethonxine 40% injectable (for cattle) online and I am having trouble determining the best non-injectable way to give this to my hen. She is drinking fine so water is an option. I am also able to give an oral dosage if someone can help me with the dosage amount. I'm having trouble understanding if I should mix with water and give orally, or mix the sulfadimethonxine into the water source daily.

Thank you guys in advance everyone is always amazing here.

Can you post a picture of the product you have and what are your chicken's symptoms?

Hey Texas Kiki, here is the pic of the product I was able to get on the internet. Hen has Coryza I'm pretty darn sure after my research here. Bad smell coming from head/face. Yellow stuff building up in lower eye lids. Scabby and crusty things on face, wattle, comb and areas above nostrils.

Most sulfa drugs are given in the water for chickens. Here is some dosages for adding sulfa to the water:

Here is an oral powder form with dosages:

I'm having a hard time converting the dosages to my 40% and into gallons. I believe the 40% is considerably stronger/more potent than most products since it's for cattle. Any help converting or helping me understand is appreciated

Dimethox is the liquid that is used in water and the chicken dose is 15 ml per gallon.
One ml of it = 125 mg, so 125 x 15 = 1875 mg per gallon.

Your 40% stuff
In water
One ml of the stuff you have is 400 ml
1875 / 400 = 4.7 ml per gallon

Orally
I'm not sure how well it works when put in water, so I might give it orally instead. I'm not positive, but I think the oral dose is 25 mg/kg or 50 mg/kg once a day.
25 mg/kg = ~0.03 ml per pound of bodyweight
50 mg/kg = ~0.06 ml per pound of bodyweight

Does that help?

Keep in mind that Coryza can easily spread to other birds. Survivors are carriers for life and will quickly infect other birds. Birds with Coryza can be infected with MG as well.
Sick birds will drink treated water very little or not at all. You'll have to administer the meds orally. For chickens, sulfadimethoxine treatment is 5 days in conjunction with baytril or tylan. Unfortunately it looks like tylan has disappeared off store shelves.

Yes thank you so much Casportpony. I am awful with math and this will help me. I think I should do the oral dosage. Since not sure if its 0.03 or 0.06 per lb of bodyweight, i suppose i should give the lesser? Is it a 5 day treatment, once per day? From what I researched, if it works it should start to work quickly.

Yes I know, she's not deathly sick, she's eating and drinking water and generally good demeanor overall, foraging and out playing. But she has the visual symptoms of Coryza, face, smell, yellow stuff in eyes.

Anyone can handle the math to figure out how to give an oral dosage of the 40% sulfadimethoxine for a 5lb hen. I'm not strong enough with math for something important like this.

I dont think water was effective enough as just simply not drinking enough and id like to give a 5 day oral dosage at this point.
