Trisullak 3A Tablet is LDI’s antibacterial line, with a tablet built on Trimethoprim, Sulfadiazine and Tylosin and a separate powder built on Trimethoprim and Sulfadiazine.
What Is Actually In It
The tablet and the powder carry different combinations. Per tablet, LDI lists 80 mg of Trimethoprim, 400 mg of Sulfadiazine (as the sodium salt), and 50 mg of Tylosin (as the tartrate salt). Per gram of powder, LDI lists 200 mg of Sodium Sulfadiazine and 400 mg of Trimethoprim, with no Tylosin. All three named compounds are antibacterials: Tylosin is a macrolide, and Trimethoprim paired with a sulfonamide like Sulfadiazine is a classic potentiated-sulfa combination. These figures are transcribed exactly as LDI states them, with no conversion or rounding.
What the Label Says It Is For
LDI’s label indicates the tablet for treatment and control of systemic and respiratory infections including Chronic Respiratory Disease (CRD), Colibacillosis, Fowl Cholera, Salmonella Pullorum and Infectious Coryza. The powder is indicated separately for prevention and treatment of Fowl Cholera, Fowl Typhoid, Salmonellosis, Mastitis, Metritis, Agalactiae, Pneumonia and Dysentery. Both lists are the manufacturer’s own, reproduced above in the fact table.
Forms It Comes In
Trisullak 3A is sold as a tablet and as a water-soluble powder, each with its own dosing schedule, including separate powder figures for prevention and for treatment. LDI’s full instructions are quoted verbatim in the dosage box above; this body text does not repeat, convert, or adjust any of those figures.
Withdrawal Period
LDI does not publish a withdrawal period for Trisullak 3A. Absence of a published figure is not the same as a zero-day withdrawal, and it is not treated as one here.
What This Page Does Not Tell You
This page transcribes what LDI publishes about Trisullak 3A. It does not tell a reader whether a bird’s symptoms match CRD, Fowl Cholera, or any of the other conditions on the label; several of those diseases produce overlapping symptoms that even an experienced keeper cannot reliably tell apart by eye. Take the bird’s symptoms to a veterinarian, an agrivet, or the local agriculture office before deciding on treatment.
