Sulfamethazine (CAS 57-68-1) plays a crucial role in maintaining the health of swine herds, particularly in managing common and often devastating bacterial infections like colibacillosis (bacterial scours) and bacterial pneumonia. As a trusted supplier of pharmaceutical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Sulfamethazine to support swine producers in their efforts to raise healthy, productive pigs.

Addressing Swine Bacterial Infections
* Porcine Colibacillosis (Bacterial Scours): Caused primarily by enterotoxigenic strains of *Escherichia coli*, this condition is a major cause of mortality in young piglets. It leads to severe diarrhea, dehydration, and rapid decline. Sulfamethazine is effective in controlling the *E. coli* infections that contribute to scours.
* Bacterial Pneumonia: *Pasteurella spp.*, particularly *Pasteurella multocida*, are common agents of bacterial pneumonia in pigs. This respiratory disease can lead to reduced growth rates, increased susceptibility to other infections, and significant economic losses. Sulfamethazine's efficacy against *Pasteurella* makes it a key treatment option.

Administration and Treatment Strategies
Sulfamethazine is typically administered to swine orally, most commonly mixed into their feed or drinking water. For treating specific outbreaks, a strategic approach is often employed. For instance, a common treatment regimen involves a higher dose for the first day of treatment, followed by a reduced dose for the subsequent two to four days. This approach aims to quickly establish therapeutic levels and then maintain them to ensure bacterial eradication. The exact dosage is dependent on the body weight of the pigs and the severity of the infection, with specific recommendations often provided on product labels. Ensuring that all affected pigs consume the medicated feed or water is crucial for treatment success. Regular monitoring of water and feed intake is recommended.

Withdrawal Periods and Producer Responsibility
Like all veterinary pharmaceuticals, Sulfamethazine has specific withdrawal periods that must be strictly observed before pigs can be sent to slaughter. These periods are established to ensure that residue levels in meat products remain below regulatory safety limits. For swine, a typical withdrawal period might be around 15 days. Producers have a responsibility to maintain accurate treatment records and adhere to these withdrawal times diligently. NINGBO INNO PHARMCHEM CO.,LTD. provides Sulfamethazine that meets high purity standards, supporting producers in their commitment to animal welfare and food safety. Consulting with a veterinarian is always advisable to tailor treatment plans and ensure compliance with all regulations.
