Below is info I've researched & used when dosing my birds. I've usually given a Tetracycline med concurrently also when I've given Denagard, in accordance with the manufacturer's recommendations on their site.
One of the more powerful meds for Mycoplasmas.
*Eggs are safe to eat.
Meat withdrawal: 2-5 days.
*Synergizes with Tetracylines, increasing effectives of meds, & also helping prevent E. Coli (which is possible problem after broad antibiotics).
*Don't combine with high doses of the anticoccidials monensin, narasin, or salinomycin.
*Not approved for poultry in US.
*Tastes bad. If giving in drinking water, add sweetener (preferably Xylitol or 100% juice; sugar is another option). If in food, mix in tasty mash. Check to make sure each bird still eats & drinks enough. Can divide dose into food & water to help ensure consumption.*Daily dose must be given gradually over time--NOT all at once nor in a single meal. Do NOT give undiluted or bird's system may react with extreme gagging or other symptoms.
Dose for CRD prevention: 1/2 the "treatment" dose; recommendations about # of days vary.
Reassuring note: Bacteria strains susceptible to Denegard are not able to build resistance very easily, even with underdosing or overly frequent dosing, (though over-use may imbalance bird's body other ways).
Denegard 12.5% Liquid dose:
For CRD treatment: 250 mg per litre drinking water [1/10 tsp (.55 cc) per average chicken] doses all ages at 25 mg/kg. Treat chicken for 3-5 days, or turkey for 5 days. Birds should show improvement in 1-2 days. Possibly continue treatment once/ month for a year.
