In a recent study, 11.59% of 768 pigs tested in February 2024 were found positive for Mycoplasma hyopneumoniae. As on ongoing and increasing issue this results in economic losses due to reduced growth rate, poorer feed conversion, increased medication use and a higher susceptibility to secondary pathogen.
Dr. Megan Bollin, a swine technical services veterinarian at Norbrook, outlines a comprehensive elimination process designed to ensure measurable returns on investment.
Dr. Bollin emphasizes the importance of exposing all animals on the farm within 80 days of age using intratracheal or aerosol fogging techniques. This step is critical for ensuring that all animals are uniformly exposed to the pathogen. To confirm successful exposure, rigorous diagnostics should be employed.
Following exposure, the herd must be closed for 240 days, a period during which strict biosecurity protocols must be maintained. During this time, treatment with an appropriate antimicrobial agent is essential. Norbrook offers two products for this purpose:
1. Tulieve: A clear, colorless to slightly yellow solution for injection, Tulieve contains 100 mg of tulathromycin, a macrolide antibiotic known for its effectiveness against mycoplasma.
2. Enrofox 100: A sterile, ready-to-use injectable solution, Enrofox 100 contains enrofloxacin, a broad-spectrum fluoroquinolone antimicrobial agent.
By adhering to these protocols and utilizing these treatments, the herd will no longer be shedding the organism after 240 days, paving the way for a healthier and more productive swine population
