NF-One

NF-One is Excellence’s trimethoprim and sulfadiazine tablet, sold for bacterial infections in poultry.

What Is Actually In It

Excellence’s product page names two active ingredients: Trimethoprim and Sulfadiazine, a combination commonly paired for its broadened antibacterial range. The manufacturer’s page does not state a per-tablet or per-kilogram amount for either ingredient, so no strength figure appears here. Those are the only two active ingredients captured from the manufacturer for this product.

What the Label Says It Is For

Excellence’s label states NF-One is for the treatment of gastrointestinal tract infections and other bacterial infections in poultry caused by bacteria sensitive to the trimethoprim and sulfadiazine combination. That wording is the manufacturer’s own indication, not this page’s assessment of what the tablet treats. See our antibiotics for chickens guide for general background on how antibacterial products like this are used in poultry.

Forms It Comes In

Excellence sells NF-One as a tablet, in bottles of 100. Its own dosage instructions refer to the product as a “capsule” in the “1 capsule per day” and “1 capsule in the morning & afternoon” lines; that wording is reproduced verbatim from the manufacturer rather than corrected, since the product listing itself is titled “100 Tablets.”

Withdrawal Period

Excellence publishes a withdrawal period of 5 days for NF-One, meaning 5 days should pass between the last dose and slaughter. The manufacturer does not publish a separate egg withdrawal figure, and this page does not estimate one.

What This Page Does Not Tell You

This page transcribes what Excellence publishes about NF-One. It does not tell a reader whether a flock’s symptoms match a trimethoprim-sulfadiazine sensitive infection, and gastrointestinal disease in poultry has many causes that require different treatments. Bring your bird’s symptoms to a veterinarian, an agrivet, or the local agriculture office before deciding on treatment.
