Medicines & vaccines
What each product treats, how it is given, and roughly how long it stays in the bird. Written for farmers who want to understand what their vet is prescribing.
No dosages, on purpose. This is reference material, not veterinary advice, and it contains no dosages on purpose. Dose, course length and withdrawal all depend on the specific product, the formulation and the bird — the label on the bottle and your veterinarian govern, not this page.
Vaccines
Prevention, not treatment. Timing is a judgement about maternal antibody, not a fixed calendar.
Newcastle disease vaccine
PAKISTANNewcastle disease (ranikhet) — endemic in Pakistan year-round

Fowl pox — skin lesions, and a diphtheritic form affecting the mouth and throat
WING WEB STABAnticoccidials
Coccidiosis damages the gut lining without producing obviously sick birds — it usually shows up as FCR drifting while mortality looks normal.
Antibacterials
Prescription territory. Every use selects for resistance, and every use starts a withdrawal clock.
Enrofloxacin
Bacterial infections including E. coli and Salmonella
DRINKING WATERDoxycycline
Respiratory and systemic bacterial infection, including mycoplasma
DRINKING WATERTylosin
Mycoplasma and some Gram-positive bacterial infections
DRINKING WATER, INJECTIONAmoxicillin
Susceptible bacterial infections
DRINKING WATERSupportive products
Not medicines. They help birds cope; they do not treat disease.
Biosecurity
The cheapest intervention on the farm, and the one most often skipped.
On withdrawal periods
Withdrawal periods shown here are indicative ranges drawn from published studies. They vary by formulation, dose, route, tissue and the residue limit being applied — the same molecule can differ by weeks between products. Never sell or slaughter birds on a figure from a website.
