Determining how long tulathromycin stays in goats after treatment

Concentration Determination of Tulathromycin Residues (CP-60,300) in Liver and Injection Site Tissues of Goats Receiving One Subcutaneous Injection of DRAXXIN 25 (25 mg/mL) at 2.5 mg/kg Bodyweight

NIH-funded research Iowa State University · NIH-11022650

This study is looking at how long the antibiotic Draxxin stays in goats after they get a single shot, so we can help farmers know when it's safe to eat the meat without any leftover medicine in it, making it easier to treat goats with pneumonia.

What this research studies

This research investigates the concentration of tulathromycin residues in the liver and injection sites of goats after they receive a single subcutaneous injection of the antibiotic Draxxin. The goal is to establish a scientifically-based withdrawal period for meat consumption, ensuring that the antibiotic is no longer present in the animal's system at the time of slaughter. By analyzing tissue samples, the study aims to provide veterinarians with reliable data to improve treatment protocols for bacterial pneumonia in goats. This research is particularly important as it addresses compliance issues with current treatment methods that require daily administration.

Who could benefit from this research

Good fit: Ideal candidates for this research are goat farmers and veterinarians involved in the treatment of respiratory diseases in goats.

Not a fit: Patients who do not own goats or are not involved in goat farming will not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options for bacterial pneumonia in goats, enhancing animal welfare and food safety.

How similar studies have performed: Similar research has shown success in establishing withdrawal periods for other veterinary drugs, indicating that this approach is both tested and valuable.
