Tri-Sulfa is a Belman Laboratories antibiotic combining penicillin with three sulfonamide compounds, marketed against a broad list of bacterial diseases.
What Is Actually In It
Belman Laboratories’s listing names four ingredients in Tri-Sulfa: Penicillin, Sulfamethazine, Sulfadiazine, and Sulfamerazine. The manufacturer’s page does not publish a per-ingredient amount for any of them. This combines one antibiotic class, penicillin, with three related sulfonamide compounds.
What the Label Says It Is For
Belman Laboratories describes Tri-Sulfa as an antibiotic “for recurring colds and diarrhea and various diseases including Fowl Cholera, Necrotic Enteritis, Bumblefoot, Colibacillosis,” adding that it is “formulated to help avoid antibiotic resistance.” That is the manufacturer’s own indication and marketing text, reproduced here rather than restated as this site’s own claim. The diseases named span respiratory, digestive, and skin-related conditions that require different confirmation methods, and cold or diarrhea symptoms alone do not indicate which one is present.
Forms It Comes In
Belman Laboratories’s page for Tri-Sulfa does not specify whether it is sold as a tablet, powder, liquid, or another physical form. That detail could not be confirmed from the manufacturer’s listing, so it is not stated in this page’s fact table. No dosage instructions for Tri-Sulfa could be confirmed either.
Withdrawal Period
Belman Laboratories does not publish a withdrawal period for Tri-Sulfa. An absent published figure is not the same as a zero-day withdrawal, and it is not treated as one here, which matters for an antibiotic product intended for birds that may later be eaten or produce eggs for consumption. Anyone weighing that timing should ask a veterinarian or agrivet.
What This Page Does Not Tell You
This page transcribes what Belman Laboratories publishes about Tri-Sulfa. It does not tell a reader how the product is physically administered, how much to give, or which of the several named diseases, if any, matches a bird’s actual symptoms. See /blog/antibiotics-for-chickens-philippines for general background on antibiotic use in poultry, and take a bird’s specific symptoms to a veterinarian, an agrivet, or the local agriculture office before deciding on treatment.
